5 Shops with the Best Deck Cleaning in Hamilton for a Party-Ready Deck
David Harris
| Last Updated: August 2025 Barbeque nights are all about good food, laughter, and catching up with friends and family. But nothing kills the vibe faster than worrying about someone slipping on a slippery deck or spotting mould while you’re enjoying your meat. Yikes, right?
That’s why, before you send out those invites, make sure your deck isn’t just clean, but safe too.
The good news? You don’t have to stress about finding the right people to do the job. We’ve already rounded up some of the best deck cleaning services in Hamilton that’ll take care of everything.
How much do deck cleaning services cost in Hamilton?
1. Wash Rite Hamilton
Address: 5/278 Kahikatea Drive, Frankton
Phone: +64 800 101 216
Business hours:
- Monday to Friday: 8 AM – 5 PM
- Saturday to Sunday: Closed
Wash Rite Hamilton uses their own special soap mix that’s made to kill mould and algae deep inside the wood without damaging it. This is actually important because we’ve heard some cases about cleaners ruining timber over time.
They let the soap sit for about 20 minutes so it can do its job properly before rinsing everything off. After that, they apply a wood treatment to make the deck look fresh and help protect it from future damage.
We especially like that they can clean tricky timbers like Kwila, which some companies refuse to touch. Their confidence in cleaning this type of wood just reinforces the fact that their soap is effective.
Customer feedback supports this. People say their decks went from dark and mouldy to looking almost brand new.
Quotes also seem to come through quickly. It’s great if you need the work done before an event or a change in the weather.
On the flip side, we did hear a few comments about staff being a bit unfriendly when asked questions during the job. It’s not a common complaint, but it’s something they could improve.
Brent got rid of all the problems and left everything like new
“I am so pleased with my recent Wash Rite service. Last year, Wash Rite cleaned my gutters and did a fantastic job. This year, I went all out and ordered a house wash, gutter clean and deck clean. Brent did an amazing job on the whole lot, got it done quickly and thoroughly. The deck had been full of black mould, the house had red mould in spots, and many plants were growing from the guttering. Brent got rid of all the problems and left everything like new. I have been very happy with Wash Rite and am now a loyal customer!”

2. Chemwash Exterior Cleaning Waikato
Address: 1/145 Ingram Road, Rukuhia
Phone: +64 7 854 9815
Business hours:
- Monday to Friday: 7 AM – 5 PM
- Saturday to Sunday: Closed
We can see why people in Hamilton, Cambridge, and the wider Waikato area often recommend Chemwash Exterior Cleaning.
Instead of blasting your deck with high-pressure water (which can cause splinters and damage), they use a special cleaning detergent that’s tough on dirt and mould but gentle on wood.
Your deck can keep its strength and be less slippery, which is safer for everyone.
It’s also great if you’re planning to paint or stain afterwards because the surface will be properly prepared to hold the finish longer.
They’ve also been in the business for over 30 years, and their team gets regular training. Customers say the crew is professional, works efficiently, communicates well, and takes care around plants and outdoor furniture.
However, there was one complaint we came across—not about a deck clean, but about washing a fence. A customer said the team didn’t stop when they tried to walk past on the footpath, and they ended up getting sprayed with water.
It seems to be a one-time thing, but it shows how important it is for them to be more aware of what’s happening around the work area.
Professional in every way
“I found Chemwash to be professional in every way, with excellent communication and a brilliant service. I had a high commercial building (and decking) cleaned, and they came up like brand new. I was impressed with the chap who did the wash, as he taped up all electronic keypads on the building to avoid water ingress, and he explained how he would deal with the green algae around the external heat pump machines. All debris from the building was washed away, so driveways were left clean, too. They are now spider-proofing, so cobwebs which accumulate dust do not return. Well worth getting done to keep a building well-maintained. Chemwash take pride in their work, and I would definitely use them again.”

3. Mr. Clean Exterior Washing
Phone: +64 22 407 8004
Business hours:
- Monday to Saturday: 9 AM – 6 PM
- Sunday: Closed
We appreciate that Mr. Clean Exterior Washing uses eco-friendly cleaning solutions that are safe for pets, kids, and plants. Even with that, it can still lift dirt, grime, and mould.
They use low-pressure washing and advanced water blasting to remove stains without damaging timber, composite, or other deck materials. It’s good news for those with decks with years of build-up.
Another strong point is that their service doesn’t just make your deck look better—it also protects it. The surface becomes slip-free and more resistant to future dirt.
We’ve also heard from clients that their team is very professional and leaves every job neat and tidy. They also seem to be the most affordable compared to the other decks we’ve researched.
Upon looking at other companies, we noticed that unlike the others, they’re open on weekends. You can even bundle multiple services in one visit, which makes everything convenient.
It’s safe to keep in mind, though, that most of the clients we’ve spoken with talk about availing their services on roofs or fences. So it’s hard to know how consistent their deck cleaning is.
Conner’s quote was far better than the others we received
“We needed my parents’ house and surroundings cleaned in preparation to sell, due to poor health, it hadn’t been done for many years, so it was a big job. Conner’s quote was far better than the others we received; he did an absolutely tremendous job. The results were far better than we had hoped. He’s a very diligent, hardworking young man. We would highly recommend his services.”

Very competitive rates, fabulous product, punctual and very particular
“From go to whoa, Mr Clean, aka Connor, has first-class customer service, great communication, a user-friendly website, very competitive rates, fabulous product, punctual and very particular. He even managed to clean a tricky high part of my house that other firms could not reach. My home looks incredible. I am so delighted that I’ve booked him to do my fence!! Would highly recommend this professional and friendly young man’s business!”

4. Grime Off Now
Phone: +64 21 605 864
Business hours:
- Monday to Friday: 8 AM – 5 PM
- Saturday to Sunday: Closed
Grime Off Now has over 34 years in the washing industry, which gives us the impression that they know how to do their job well.
A customer even complimented their service for cleaning their deck. He simply thought it was weathered paint, but it turned out to be years of grime, mould, and algae buildup. The transformation is hard to brush off.
One of the things that stood out in our assessment was how they communicate. Clients frequently mention that the team explain what they’re doing and the whys behind it.
We also noticed that they provide a fixed quote upfront, offer a range of options, and use safe cleaning detergents. Their quiet and gentle cleaning process also adds to the appeal.
Beyond deck cleaning, they also offer a wide range of services. One customer even used them for gutter cleaning and roof mould treatment. They’re very convenient for anyone who wants multiple exterior jobs handled by one company.
If we’re being picky, their prices can be a bit higher than the other companies we looked at. We think it’s worth it, though.
We’ve got a winner here
“Such a thorough clean. Never knew our deck was not actually painted till the waterblasting. Realised it was all mould and grime! Shorten the wait time, and we’ve got a winner here. Nonetheless, will be getting a regular service in the future.”
– Thomas Chin, Google review
All of these tasks were completed to a high standard
“Grime Off Now performed exterior house wash, gutter clearing, deck cleaning and roof mould treatment on my residence. All of these tasks were completed to a high standard, and the guy engaged to do the work made a point to talk through what he was going to do versus just working off the job sheet, ensuring all my expectations were met. I highly recommend Grime Off Now to others looking for similar work to be done on their properties.”

5. DryGutts
Address: 461 Whatawhata Road, Dinsdale
Phone: +64 22 462 9405
Business hours: Monday to Sunday: Open 24 hours
From what we’ve gathered, DryGutts’ standout pro is the quality of their deck cleaning itself.
Customers have mentioned that older decks (even 5-year-old wooden ones) look brand new after their treatment. They really use the right cleaning techniques and products that not only clean but also restore the wood’s appearance.
The team, led by Mitchell, was often praised for their consistency and attention to detail. Clients frequently mention that they’re courteous, helpful, and willing to go the extra mile. They make the whole process smooth and stress-free.
The Full House Package that they offer adds extra value beyond just the deck. It includes house washing, roof treatment, and gutter cleaning. It also comes with concrete surface cleaning, a free exterior window clean, and insect control treatment.
Their quoting process is also transparent, often including an aerial plan of the property and detailed explanations of what will be done.
We also noticed that their 24/7 contact is very useful, even if the actual cleaning doesn’t happen at night.
However, deck cleaning isn’t offered as a standalone service. It might be harder for people who only want their deck done without committing to a full house package.
Appreciate the great effort, Team
“Mitch did a wonderful job on the exterior of my place, including the gutters, roof and the deck. We had spiders living around the windows, and now they’re sparkly!! Appreciate the great effort, Team.”
