Most of us don’t think too much about dampness or mould until it becomes obvious. It’s easy to brush it off as “just part of living in New Zealand.” And to be fair, moisture is part of life here. Between our climate and older housing stock, a bit of dampness isn’t unusual. But it’s also not harmless.

That constant exposure to moisture can wreak havoc behind the scenes. Damp conditions don’t just impact air quality or comfort; they also slowly break down the surfaces in your home. And one of the first places that damage shows up? Your grout and tiles.

We have taken recent data from the Housing in Aotearoa New Zealand 2025 report (Stats NZ) to look at how widespread this issue is across Kiwi homes, what damage it’s actually causing to your home and how you can stop it.

Grout lines don’t usually get much attention. Most of us wipe the tiles, spray a bit of cleaner, and move on with our day. But the reality is, grout can quietly collect more than just a bit of soap scum.

So, are your grout lines a biohazard? Not by default. But over time, especially in bathrooms and kitchens, they can trap moisture, bacteria, mould, and allergens if they’re not properly cleaned and maintained.

Let’s break down what’s really going on between your tiles and how GroutPro can help you actually fix it.

Before you start knocking down walls or building that new deck, there’s one thing you need to know: Does this project require building consent? It’s not the most exciting part of a renovation, but it’s one of the most important!

The tricky part is that some projects clearly need consent, some clearly don’t, and others sit somewhere in between. In this guide, we’ll break down the rules and walk through the most common home upgrades, so you can move forward with clarity and confidence.

• The Building Consent Process

A building consent is approval from your local council confirming that your planned work complies with the New Zealand Building Code. While your local council manages the process, the rules themselves are set nationally under the Building Act 2004.

Building consent forms part of a national system designed to ensure homes across New Zealand are built safely and to a consistent standard. Under the Building Act 2004, the law sets out:

• What counts as building work
• When consent is required
• How applications are assessed
• What inspections must occur

The technical standards sit within the New Zealand Building Code. The Code doesn’t tell you exactly how to build; it sets the performance standards your project must achieve.

Whether building consent is required for kitchen and bathroom renos depends on whether the work is classified as “building work”. Under Section 40 of the Building Act, building work must not be carried out without building consent unless it is exempt under Schedule 1.

Schedule 1, Part 1 allows exemption for general maintenance and like-for-like replacements. This typically includes:

• Replacing sanitary fixtures in the same position
• Installing new cabinetry or benchtops
• Replacing tiles or wall linings
• Regrouting or resurfacing

If you are not altering plumbing, drainage, or structure, building consent is generally not required.

Consent is required where the renovation involves work that must demonstrate compliance with the New Zealand Building Code, including:

• Adding or relocating toilets, showers, or sinks (Clause G12 – Plumbing and Drainage)
• Modifying drainage systems (Clauses G12 and E1 – Surface Water)
• Removing or altering load-bearing walls (Clause B1 – Structure)
• Creating new wet areas or altering floor levels affecting moisture control (Clause E3 – Internal Moisture)
• Converting a non-wet area into a bathroom, which may trigger change-of-use considerations under Section 115

If your project changes the layout, plumbing location, drainage, or structure, a building consent will be required before work begins

You generally won’t need building consent if:

• The deck is 1.5 metres high or lower.
• It’s not part of a larger structural alteration.
• It’s built to comply with the New Zealand Building Code.

This exemption covers most standard ground-level and low-elevation decks.

You generally will require a building consent if:

• The deck is more than 1.5 metres above ground level (Clause B1 – Structure).
• The deck supports a roof or forms part of a covered outdoor area (Clauses B1 – Structure and B2 – Durability).
• It ties into the structural bracing of the house (Clause B1 – Structure).
• There is a fall of more than 1 metre requiring safety barriers (Clause F4 – Safety from Falling).

It’s also worth noting that safety barriers are required where there’s a fall of more than 1 metre, regardless of whether building consent is required.

As a simple rule: if your deck is low and standalone, you’re usually fine. If it’s higher, covered, or structurally integrated with your home, you’ll need consent before you start.

• The wall is 1.5 metres high or lower.
• It’s holding back the garden soil only.
• There’s no driveway, building, or vehicle load above it.

• The wall retains more than 1.5 metres of ground (Clause B1 – Structure).
• The wall supports a surcharge load, even if it is under 1.5 metres (Clause B1 – Structure).
• The design requires engineered structural support or specific durability performance (Clauses B1 – Structure and B2 – Durability).

Once a retaining wall starts holding back significant height or weight, it moves firmly into consent territory. It’s far easier to confirm the requirements upfront than to fix a non-compliant wall later.

In most cases, you won’t need building consent for a standard residential fence. The key factor is height, and once you know the threshold, the rule is straightforward.

• The fence is 2.5 metres high or lower.
• It’s a typical standalone boundary or privacy fence.
• It’s not supporting another structure.

That covers the vast majority of timber boundary fencing around Kiwi homes.

• The fence is higher than 2.5 metres.
• It forms part of a larger building structure.

Standard fencing is usually straightforward. Once you start pushing height limits, consent comes into play. It’s also worth checking your local district plan for height or boundary restrictions; those are planning rules rather than building consent rules, but they still matter.

Garages are where building consent rules can shift quickly, especially if you’re changing how the space is used. There’s a big difference between building a simple detached garage and converting an existing garage into a living space.

If you’re converting a garage into a bedroom, office, or any habitable room, building consent is required. Why? Because you’re changing how the space is used. Under Section 115 of the Building Act 2004, a change of use must ensure the building complies, as nearly as reasonably practicable, with the Building Code for its new purpose.

• Convert the garage into a bedroom or living space (Section 115 – Change of Use).
• Add insulation to meet current standards (Clause H1 – Energy Efficiency).
• Install plumbing for a bathroom or kitchenette (Clause G12 – Plumbing and Drainage).
• Modify structural elements (Clause B1 – Structure).
• Alter fire separation requirements (Clause C – Fire Safety).

Once a garage becomes a habitable room, it must meet the same performance standards as the rest of the home. If the space is being used for sleeping or living, consent needs to be in place before work begins.

For new garages, size and plumbing are the deciding factors.

A detached, single-storey garage may be exempt from consent if it:

• Is no larger than 30 square metres.
• Does not contain sanitary plumbing.
• Meets boundary and height limits.
• Complies with the Building Code.

If the garage exceeds 30m², is attached to the house, includes plumbing, or involves structural complexity, building consent will be required (Clauses B1 – Structure and B2 – Durability).

Once a garage moves beyond simple standalone storage, it shifts into consent territory, and it’s best to confirm the requirements before construction starts.

Louvre roofs and pergolas sit in a grey area. The deciding factor isn’t what you call it, it’s how it’s built, its overall size, and whether it becomes part of the house.

• The structure is an open pergola (not fully roofed or enclosed) and under 30sqm in size.
• It does not significantly affect the structural integrity of the house.
• It complies with the Building Code.

Simple, standalone garden pergolas will often fall into this category.

• The structure is over 30sqm in size.
• The louvre roof system is attached to the dwelling and transfers structural loads (Clause B1 – Structure).
• The structure is fully roofed and creates a covered outdoor area (Clauses B1 – Structure and B2 – Durability).
• The design requires specific engineering for wind or structural loading (Clause B1 – Structure).
• The structure forms part of the building envelope and must manage weather tightness (Clause E2 – External Moisture).

Once a pergola becomes roofed and structurally integrated with the home, it moves into consent territory. It’s far easier to confirm requirements upfront than to retrofit compliance later so talk to your local authorities.

Artificial grass and basic landscaping are usually straightforward. In most cases, laying synthetic turf isn’t considered building work, but the structures underneath it can be.

• Installing small areas of artificial grass
• Minor ground preparation
• Basic paving
• General garden landscaping

If you’re not building structural elements or changing drainage, consent is typically not required.

• Constructing a retaining wall beyond the 1.5 metre threshold (Clause B1 – Structure).
  Carrying out significant earthworks that affect stability or drainage (Clause B1 – Structure).
  Installing drainage connected to stormwater systems (Clause E1 – Surface Water).
  Building structural platforms or decks (Clauses B1 – Structure and B2 – Durability).
  Installing large areas of artificial grass if the council deem it a non-permeable covering.

Once landscaping moves beyond surface-level work and starts altering structure, load, or drainage, it shifts into consent territory. It’s worth confirming the requirements before the ground is broken.
Similarly, some councils have differing views on artificial grass. Check with your local authority first.

If work is done without building consent when consent was required, it can cause issues later, often when you least expect it. Councils can issue a Notice to Fix, requiring the work to be inspected, altered, or formally approved through a Certificate of Acceptance. That process is usually more time-consuming and more expensive than getting consent sorted properly from the start.

Unconsented work can also complicate selling your home. Buyers and their lawyers often ask for consent documents and a Code Compliance Certificate (CCC). If they’re missing, it can delay settlement or affect the sale price.

If your project requires building consent, here’s what the process typically looks like from start to finish:

1. Confirm consent requirements: Before you begin, confirm whether your project requires building consent or falls under a Schedule 1 exemption. If there’s any uncertainty, it’s worth checking with your local council or getting professional advice early.
2. Prepare plans and supporting documentation: You’ll need drawings and specifications that show how the proposed work will comply with the New Zealand Building Code. For structural or more complex projects, this may include engineering calculations or documentation from a Licensed Building Practitioner (LBP).
3. Submit your application to the council: Your local council acts as the Building Consent Authority (BCA). Once your application is lodged and accepted as complete, it enters the formal assessment process.
4. Council assessment (up to 20 working days): By law, councils have 20 working days to process a complete application. If they request further information (often called an RFI), the processing clock pauses until that information is supplied.
5. Consent is issued: Once approved, you’ll receive your building consent documentation outlining approved plans and required inspections. Work can then begin.
6. Inspections during construction: Council inspections must be booked at key stages of the build, for example, foundations, framing, drainage, waterproofing, or final completion. Work must not proceed past certain stages without an inspection sign-off.
7. Code Compliance Certificate (CCC): After the final inspection is passed and all documentation is complete, the council issues a Code Compliance Certificate (CCC) confirming the work complies with the approved consent and the Building Code.

Handled properly, it’s a structured process designed to protect homeowners, not slow projects down.

Building consent doesn’t need to be complicated, but it does need to be handled properly. The key is understanding when consent is required, what the rules say, and getting clarity before work begins. If you’re planning an upgrade and aren’t completely sure where your project sits, it’s far easier to check early than to fix compliance issues later.

At The ProGroup, we work with these rules every day. We understand when consent applies and how to navigate the process properly when it does. If you’re unsure about your next project, get in touch. We’re happy to point you in the right direction before you (or we) pick up the tools.

Bathroom mould is one of those problems that feels impossible to beat. You scrub it away, everything looks clean for a while, and then a few weeks later it’s back. The good news? Mould isn’t inevitable. With the right habits and a few smart fixes, you can keep your bathroom tiles mould-free long term.

In this guide, we’ll explain why mould keeps coming back, what everyday habits make it worse, and how GroutPro can help.

Kiwis love a bit of DIY. Whether it’s painting the spare room, laying a new deck, or finally tackling that kitchen that’s been “on the list” since 2018. We’ve got a proud tradition of rolling up our sleeves and giving it a go.

But not every job is a weekend project, and not every myth about DIY holds up. In fact, believing a few of these “she’ll be right” assumptions can end up costing you more in time, money, or even safety.

So, before you grab the power tools or start ripping up floorboards, let’s bust some of New Zealand’s biggest DIY myths and find out when it really pays to call in the pros.

It’s easy to think DIY means instant savings, no labour costs, no invoices, just you, a Bunnings receipt, and a dream. But that “cheap” project can quickly snowball. A 2024 Clever Real Estate survey found 61% of homeowners blew their renovation budgets, with nearly half admitting it was due to underestimating DIY costs or fixing their own mistakes. Add in tool purchase or hire, material waste, and weekends lost to rework, and those savings start to fade fast.

Professionals buy materials in bulk, work faster, and don’t have to redo their own work. The ProGroup teams, for example, have systems honed over thousands of projects, saving homeowners both money and headaches.

Verdict: DIY can save you a few bucks upfront, but pros save you from expensive redos later.

YouTube makes it look easy: a five-minute video, a few tools, and suddenly you’re a DIY expert. But what those videos don’t show are the mishaps, the compliance headaches, the hours spent fixing uneven cuts and crooked finishes, or often even giving the correct advice (anyone can post a YouTube video right!).

In 2024, ACC accepted around 19,500 DIY-related injury claims, many caused by power tool misuse and ladder falls; two of the most common mistakes made by “first-time” renovators. What looks straightforward online can quickly turn dangerous in real life, especially when you’re juggling unfamiliar tools or materials.

Professional tradies spend years mastering the techniques, safety habits, and product knowledge that YouTube can’t teach. They know which materials suit New Zealand’s climate, which shortcuts actually work, and which ones will cause leaks, cracks, or worse.

Verdict: Watching a video is easy. Doing it safely and to a professional standard is something else entirely.

We all love a bargain, but when it comes to home improvement, the cheapest quote isn’t always the smartest one. Low prices often come with hidden costs: rushed prep work, low-grade materials, or a finish that looks great… for about a month.

What looks fine on day one can start cracking, peeling, or fading months later, and by then the “savings” are long gone. Many homeowners end up paying twice, once for the cheap job and again to have it done properly.

Professional tradespeople price their work based on getting it right the first time, using quality products, proven methods, and warranties that back it all up. That’s what real value looks like: lasting results that don’t need fixing next season.

Verdict: Cheap jobs fade fast. Quality work from the pros saves money, time, and headaches in the long run.

“Surely I don’t need consent to add a wall here or change the plumbing a bit?” Famous last words.

The Ministry of Business, Innovation and Employment (MBIE) makes it clear: many small jobs still require building consent or must be carried out by a licensed professional. Electrical, plumbing, structural, or load-bearing work is a big no-no for DIY.

Unconsented work can also void your insurance or delay a property sale; a costly mistake that many homeowners only discover when it’s too late.

Verdict: When in doubt, check before you start, or hire a pro who already knows the rules.

It’s easy to assume your insurance will cover anything that goes wrong at home, but not all claims are created equal. Most insurers make it crystal clear: if damage is caused by unconsented or unqualified work, you could be on your own.

AA Insurance, for example, warns that policies may not cover losses resulting from faulty DIY electrical and plumbing work. And according to Consumer NZ, insurers routinely deny claims linked to unlicensed building, wiring, or gasfitting, even if the damage appears unrelated.

Always read your policy wording carefully; many require that work be carried out by a qualified or licensed professional. Or else those “small jobs” can turn into expensive lessons fast.

Verdict: DIY might feel thrifty, but voided cover is about as costly as it gets.

A slick new kitchen or bathroom can absolutely boost your home’s appeal,  but that doesn’t mean every renovation will add value. Some upgrades simply don’t return what you put in, especially if they’re poorly planned or low quality.

Data from OneRoof shows that adding an extra bedroom to a typical 1980s house in West Auckland added only around NZ$12,600 in value, hardly a windfall once you factor in construction costs. Financial advisors in New Zealand also warn about over-capitalising: spending more on a renovation than the market will reward can actually leave you worse off.

Poor workmanship, non-compliant work, or finishes that don’t suit the home’s value bracket can also reduce buyer interest. Professional work, on the other hand, adds confidence, longevity, and genuine resale appeal.

Verdict: Not all renovations are created equal; value comes from smart design, solid workmanship, and getting it done right the first time.

DIY has its place; fixing a fence panel, repainting a bedroom, or hanging shelves can be rewarding. But for anything bigger, riskier, or more permanent, the myth of “saving money” rarely holds true. Professional work means safety, compliance, and long-lasting quality. It means fewer surprises when you sell, and no awkward conversations with your insurer.

So before you grab the toolbox this weekend, ask yourself one thing: Is it worth the risk?

If not, give The ProGroup a call. Our expert teams across New Zealand handle everything from painting and fencing to landscaping and garage makeovers. Done once, done right, and built to last.

Kiwis love a good home project, but when it comes to cost, things can get murky fast. Ask three tradies and you’ll probably get three different numbers. That’s why the team at The ProGroup has pulled together the 2025 Home Improvement Cost Index. We’ve broken down the average prices Kiwis are paying for the most common home improvement projects.

These figures are based on up-to-date averages from across New Zealand. They’re not fixed quotes, but they’ll give you a realistic ballpark before you start calling around.

A perfect lawn without mowing, mud, or maintenance, that’s the beauty of artificial grass. In New Zealand, artificial lawn installation can cost between $180 and $450 per square metre, depending on the turf quality, base preparation, and site access.

The groundwork is what drives the price. Old grass and soil often need removing, and a solid crushed rock base must be laid to keep the surface smooth and well-drained. Premium turf with UV protection and realistic thatch adds to the cost but lasts far longer than budget options.

While artificial lawns are an investment upfront, they quickly pay off in time saved and lower upkeep. No watering, mowing, or muddy footprints, just a perfect patch of green every day of the year. Talk to our GrassPro team for a tailored quote.

Nothing dates a home faster than grimy grout or dull tiles, but restoring tiles doesn’t have to mean a full renovation. In New Zealand, most homeowners pay around $20 per m² for deep cleaning and $35+ per m² for grout sealing, with a minimum service cost of roughly $180. Regrouting is difficult to give a price indication without viewing the area.

The cost depends on tile size, surface condition, and how much grime or mould needs removing. Deep extraction cleaning removes years of buildup, while recolouring and sealing protect the grout from future staining. Small repairs to cracked grout or loose tiles can be handled at the same time, saving on future maintenance.

Outdoor timber furniture weathers quickly under New Zealand’s harsh sun and rain. Fading, cracking, and greying wood are common signs that it’s due for a refresh, but a full replacement isn’t always necessary. Professional timber furniture restoration can bring tired pieces back to life for a fraction of the cost.

In New Zealand, wooden furniture restoration prices typically range from $300–$1,000+ for full restoration, depending on size, number of items, wood type, and finish. The process often includes deep cleaning, sanding, and refinishing with protective oils or stains that restore natural warmth while shielding the timber from UV and moisture.

If you love spending time outdoors, a bit of shelter and privacy can make all the difference. Outdoor roller blinds and louvred shutters are a simple way to turn your deck or pergola into a space you can enjoy year-round.

In New Zealand, blinds can cost between $1000 and $2000 for a motorised 3.5 metre wide setup, while aluminium folding shutters of the same size range from $3000 to $5000 depending on the features.

The difference comes down to size, automation, and finish. Motorised blinds add the push-button convenience Kiwis love, while solid shutters give you sturdy protection from wind, rain, and nosey neighbours. Both options help you make the most of your outdoor area; whether it’s sunny, breezy, or somewhere in between.

For such a small room, bathrooms carry a hefty price tag. A full makeover in New Zealand typically lands between $22,000 and $25,000, and it’s easy to see why.

Renovating a bathoom means cramming almost every trade into one tight space; builders, plumbers, electricians, tilers, and painters all need to be involved. Labour adds up quickly, especially if pipes or wiring need moving. Waterproofing is another non-negotiable cost; done right, it protects your home from leaks, but it requires skilled work and specialist materials.

Then there are the fittings. A new shower, vanity, and toilet alone can eat through much of the budget, and premium finishes like tiled walk-in showers or custom glass push things even higher. Bathrooms are pricey because they demand precision. But when done properly, they add comfort, style, and serious resale value to your home.

Of course there is an alternative if the main fixtures and surfaces are in salvageable. GroutPro can make your existing bathroom like new by replacing stained grout, mouldy silicone, and bringing the clarity back to to waterstained glass showers. This can be done for a few thousand dollars.

If your garage is cold, dusty, or just a bit of a dumping ground, a new layer of garage carpet can make a world of difference. It’s one of those upgrades that once you’ve got it, you wonder how you ever lived without it. In New Zealand, you’re usually looking at around $500 to $800 for a single garage, or about $1000 to $1600 for a double, that’s supply and install sorted. Quality of the carpet and preparation of the floor will determine the actual cost. Correct floor preparation is extremely important so make sue it is included in the quotes you receive.

Garage carpet isn’t just about looks. It keeps the place warmer, quieter, and cleaner, and it’s tough enough to handle cars, tools, or the kids’ bikes. Suddenly, that forgotten space becomes somewhere you actually want to spend time, maybe a home gym, hobby zone, or just a tidier spot to park the car.

For many Kiwis, the dream home includes a deck, pergola, or louvre system that makes outdoor living easy year-round. But creating that space isn’t pocket change. A solid outdoor addition typically runs between $15,000 and $50,000.

The costs come from both structure and finish. Timber pergolas are generally cheaper, but aluminium or steel frames last longer and bump up the price. Add in a roof, clear panels, or automation, and you’re quickly into premium territory. The size of the build also matters; a modest patio cover might be straightforward, while a full entertainer’s space with decking, roofing, and lighting is a bigger project with more labour.

Outdoor living additions are pricey because they’re essentially an extension of your house. Done right, though, they create a seamless indoor-outdoor flow and add real lifestyle value you’ll use every day.

Nothing says Kiwi living like a deck out the back for BBQs and summer evenings. But building one comes at a cost. In New Zealand, you’re generally looking at upwards of $500 per square metre, with basic pine decks sitting lower and hardwood or composite options pushing much higher.

The materials are a big driver; treated pine is the affordable standard, while hardwoods and composites bring durability and style, but at double the price. Size and height matter too. A ground-level deck is straightforward, while an elevated build with stairs, balustrades, or council consents quickly adds labour hours and compliance costs.

It’s not just timber and nails either, you’re paying for proper piles, framing, fixings, and finishing that ensure the deck lasts through years of weather and wear. Done right, a deck isn’t just an outdoor platform; it’s an extension of your living space and a real value booster.

The right fence can make or break your street appeal. It’s the frame around your property, and like any good frame, it can either enhance or cheapen the picture inside. In New Zealand, the average cost sits upwards of $200 per metre, though the final price depends on the materials, height, and terrain.

Timber paling fences are the classic choice and the most affordable, but even here, the costs vary with timber grade and post spacing. Go for Coloursteel, PVC, or decorative panel systems, and the price quickly jumps into the $250+ per metre range. Site conditions also make a difference; sloping ground, tricky soil, or difficult access all add labour time.

It’s tempting to cut corners with a fence, but the structure is only as good as its posts and foundations. Talk to Deck&FencePro about the best option for your property.

Running out of space? You’re not alone. Most Kiwi garages end up cluttered with gear, tools, and things we “might need one day.” That’s where smart storage and loft ladders come in, giving you extra room without needing a bigger house. In New Zealand, professional installation usually costs around $900–$1,200 for supply and install.

A solid storage setup can completely change how your garage works. Wall-mounted shelves, cabinets, and workbenches keep everything tidy and off the floor, while a loft ladder opens up the roof space for all those bulky items you don’t use every day. It’s a simple, affordable way to get organised and make the most of the space you’ve already got and can start from as little as a few hundred dollars.

Home improvements don’t come cheap, but they also don’t need to be a mystery. Knowing the average costs of common home improvement projects helps you budget realistically and avoid nasty surprises. Every home and section is different, so your numbers may sit a little higher or lower. The key is to plan ahead, get a couple of quotes, and invest in the jobs that deliver the most value for your lifestyle and property.

And if you’d rather skip the stress of juggling multiple tradies, The ProGroup has you covered. From tiles, lawns, decks, fences, and beyond, our specialists get it done right the first time.

Is your kitchen looking a bit worse for wear? Faded grout lines and stained tiles can make even the nicest space feel dull and dated. The good news is, you don’t need a full renovation to bring back that fresh, clean look. Regrouting is a simple, cost-effective way to make your tiles look brand new again.

This guide walks you through everything you need to know about how to regrout kitchen tiles, from the tools you’ll need to the steps that’ll make your kitchen shine again.

• Regrouting is an easy, cost-effective way to make your kitchen tiles look brand new.
• The process includes removing old grout, cleaning, applying new grout, and sealing it for protection.
• Choosing the right grout type, sanded, unsanded, or epoxy, ensures a durable and lasting finish.
• Having the proper tools and taking your time helps achieve that smooth, professional look.
• Regular cleaning and resealing will keep your grout fresh and your kitchen looking its best.

Grout doesn’t last forever, and in high-traffic areas like the kitchen, it can start showing its age faster than you’d think. Every day cooking, spills, and steam slowly break it down, leaving your grout looking tired and uneven.

Here are some clear signs it’s time to regrout:

• Cracked, discoloured, or missing grout between tiles.
• Stains that won’t budge, no matter how much you scrub.
• Persistent mould or a damp, musty smell.

If you’ve noticed any of these, a fresh application of grout can make your kitchen look new again, without the cost of a full renovation.

Before you start regrouting, make sure you’ve got the right gear on hand. Here’s what you’ll need:

• Grout saw or oscillating tool: to carefully remove the old grout without damaging your tiles.
• Vacuum or brush: for cleaning out the joints and getting rid of any leftover dust or debris.
• Grout float and sponge: to apply the new grout smoothly and clean up any excess.
• Bucket and mixing paddle: for mixing your grout to the right consistency.
• New grout: choose between sanded, unsanded, or epoxy, depending on your tile type and joint size.
• Sealant and applicator: to protect your new grout from moisture and stains once it’s dry.
• Safety gear: gloves, goggles, and painter’s tape to keep things tidy and protect yourself while you work.

Having the right tools not only makes the process smoother but also helps you get that crisp, professional-looking finish.

Choosing the right grout makes all the difference in both look and longevity. Sanded grout suits kitchen floors and wider joints, offering strength and durability. For walls and splashbacks, unsanded grout gives a smoother, cleaner finish. If you want the toughest option, epoxy grout is waterproof, stain-resistant, and perfect for busy kitchens. When it comes to colour, go light for a seamless look or darker for contrast and easier maintenance.

Regrouting your kitchen might sound like a big job, but with the right tools, a bit of patience, and some careful technique, it’s totally doable. Here’s a step-by-step guide to help you get great results without the stress.

Before you start, take a close look at your tiles. Check for any loose or cracked ones that might need to be repaired or replaced first. You don’t want to grout over existing damage. Make sure the area is dry and clean, especially around benchtops or splashbacks.

Use a grout saw or oscillating tool to carefully scrape out the old grout between the tiles. Take your time to avoid chipping the edges. If you’re working near delicate surfaces like splashbacks, painter’s tape can help protect the tile edges.

Extreme care must be taken to not chip the edges of the tiles, or cut too deep which could damage waterproofing membranes or under-floor heating elements. If you are not confident call your local GroutPro specialist.

Once all the old grout is gone, vacuum or brush out the joints to remove any leftover dust and debris, and give the tiles a good clean to remove grease and dirt. A clean tile surface ensures the new grout adheres properly.

Follow the grout manufacturer’s instructions for mixing; consistency is key here. You’re aiming for something smooth and lump-free, similar to thick peanut butter. If you’re working on a large area, only mix what you can apply in about 30 minutes to avoid it drying out too fast.

Use a the correct float to spread the grout across the tiles at a 45° angle. Work diagonally across the joints so the float presses the grout deep into the gaps. Apply firm, even pressure, and make sure every joint is filled. Work in small sections so you can smooth and clean excess away as you go.

After about 10–15 minutes, the grout will start to set slightly. Use a damp (not soaking wet) sponge to gently wipe away any excess from the tile surface. Rinse the sponge regularly and keep the strokes light; too much water can weaken the grout before it cures. Once it starts to dry, you might see a light haze on the tiles. That’s normal; it can be buffed off later with a dry cloth.

Leave the grout to dry for at least 24 hours, or up to 48 hours for larger areas or humid environments like kitchens. Avoid walking on the area or splashing water until it’s fully cured.

Once the grout is fully dry, apply a quality sealant to protect it. Use a small applicator brush or roller and run it evenly along the grout lines. Allow it to dry completely before using the area again. Sealing not only makes your grout last longer but also makes cleaning easier down the track.

Once you’ve finished regrouting your kitchen, maintenance is key to ensure you don’t have to circle back and do it again any time soon. Here are a few good habits that will have a huge effect on your new grout:

• Clean regularly using a mild, pH-neutral cleaner. Avoid bleach or acidic products that can damage grout.
• Reseal every 12–18 months to protect against moisture, stains, and everyday wear.
• Wipe up spills straight away to prevent discolouration or grime build-up.
• Use soft brushes or cloths instead of abrasive scrubbers to keep tiles and grout looking smooth and fresh.

With a little regular care, your kitchen will keep that just-regrouted look for years to come.

A kitchen regrout can completely transform your space. No renovation required. It’s one of those small upgrades that makes a big difference to how your home feels every day.

If you’d rather skip the mess and get a perfect finish, talk to your local GroutPro team. Our specialists can restore your kitchen tiles quickly and professionally, leaving your space looking good as new.

Summer is the home-selling season across New Zealand. With the warmer weather, longer days, and more motivated buyers, now’s the perfect time to list your property. But when competition heats up, presentation becomes everything.

Most sellers focus on curb appeal and staging, but there’s one simple detail that often gets overlooked: your tiles and grout. Fresh, spotless tiles can instantly lift a room, making kitchens, bathrooms, and entryways feel cleaner, newer, and better cared for. A professional tile and grout refresh from GroutPro can be the quick pre-sale boost your home needs to stand out this summer

Ask any real estate agent, and they will tell you kitchens and bathrooms are what sell houses. They’re the first places buyers check, and the smallest details can leave a lasting impression. Dull tiles, mouldy grout, or discoloured silicone can make even a modern space look neglected, while clean, polished surfaces create an instant “wow” factor.

In competitive markets like Auckland and Wellington, where buyers have plenty of options, presentation counts. A home that looks well-maintained feels more valuable, and that perception often translates into stronger offers.

If your tiles have lost their shine, and no amount if scrubbing will get your grout clean, a deep professional clean can bring them back to life. GroutPro’s expert teams use specialised equipment and eco-friendly products to remove grime, soap scum, and years of built-up residue that standard cleaning can’t touch.

This cleaning makes a big difference at open homes where bright, fresh interiors can really make your home stand out. With tile and grout cleaning, kitchen splashbacks, bathroom floors, and tiled hallways can all look like new, helping your home feel brighter and more inviting.

Bathrooms can make or break a sale, so it’s worth giving yours a quick facelift. Fresh grout makes tiles look new again, while resealing protects against mould and moisture, two red flags for buyers.

GroutPro’s grout colour sealing service is a smart upgrade before selling. It not only restores grout but adds a protective layer that repels stains and keeps your bathroom looking spotless for years. The result is a cleaner, more modern space that tells buyers your home’s been cared for down to the last detail.

First impressions matter, and that includes the front door, patio, and pool area. Outdoor tiles take a beating from weather and foot traffic, so giving them a good clean can instantly boost curb appeal.

A professional refresh can remove moss, grime, and oil stains, while non-slip sealing adds safety and polish. Whether it’s the entryway, deck, or courtyard, clean tiles make your home feel well-loved before potential buyers even step inside.

It’s amazing how often buyers notice a single chipped tile. Small imperfections can give the impression that a home hasn’t been maintained, even when the rest looks great.

Our damaged tile and grout repair specialists can often fix or replace individual tiles seamlessly, saving you the cost of a full refit. They also use durable epoxy grout that’s waterproof and resistant to staining, perfect for showers, bathrooms, and outdoor areas that need to look their best before the first open home.

This kind of quick, professional repair not only improves aesthetics but also shows buyers your property has been cared for properly, helping eliminate reasons for them to negotiate the price down.

Even spotless tiles can look tired if the silicone around them is mouldy or discoloured. It’s one of those small details buyers always notice, especially in showers and around sinks.

GroutPro’s silicone removal and replacement service gives these areas a crisp, new look that brightens up the whole space. Fresh silicone not only improves appearance but also helps prevent leaks and mould, an easy, inexpensive update that can make your bathroom feel brand new.

When selling, small improvements can make a surprisingly big impact on value and buyer perception. A full renovation might not be necessary; often, all it takes is a professional clean and a few minor repairs to bring tiles back to life.

Clean, well-sealed tiles signal to buyers that the home is move-in ready, with less work to do post-purchase. And because presentation influences emotion, these details can help your home feel more desirable, a major advantage in competitive summer markets.

Even if you’re not selling right away, a GroutPro refresh helps preserve your tiles and makes everyday cleaning easier, so you can enjoy the results now and benefit later when you do decide to list.
