Top 5 Picks for the Best Deck Cleaning in Christchurch When Your Deck Needs Help
The other day, I walked out to enjoy my morning coffee on the deck and nearly slipped. Turns out, it was covered in moss and grime I hadn’t even noticed building up. That’s when I realised our deck had seen better days.
If you’ve had a similar moment, you know it’s probably time for a proper clean. And while scrubbing it yourself sounds like a nice idea, it’s way easier and safer to call in the pros.
That’s why we’ve put together a list of trusted deck cleaning services in Christchurch, so just like us, you can skip the scrubbing and get back to enjoying your outdoor space.
How much do deck cleaning services cost in Christchurch?
1. Pure Services Christchurch

Pure Services uses a soft wash system instead of high-pressure washing. If you’ve ever seen pressure washing peel wood or leave marks, you’ll get why this matters.
Their approach uses low-pressure water with eco-friendly cleaners. This helps them get rid of mould, grime, and algae without damaging the wood. If you have an older deck or one that’s made of softer wood, they are a great choice.
They also use an ozone-based cleaning system, which doesn’t use harsh chemicals. That means it’s safer for your family, pets, and garden.
However, the ozone can leave a bit of a chlorine scent right after treatment. It’s not bad, but just noticeable for a little while.
We also loved that they offer more than just deck cleaning. They also do house washing, gutter cleaning, and even spider deterrent treatments. It’s convenient if you want to get everything done at once.
Amazing job!
“These guys did an amazing job cleaning my house/deck. I would recommend it.”

Prompt, thorough, and extremely professional
“I recently hired Pure Services for mould treatment, and I couldn’t be happier with the results. They were prompt, thorough, and extremely professional in addressing the mould issue in my home. The team’s attention to detail was impressive, ensuring that every nook and cranny was mould-free. I strongly recommend their services to anyone dealing with mould problems; they certainly exceeded my expectations.”

2. Wash Rite

What made Wash Rite stand out to our team was their special soap. It’s not your usual cleaner. They made the soap themselves, and it digs deep into the wood to get rid of mould and algae.
Instead of blasting the deck with high-pressure water, they use this soap and let it sit for about 20 minutes. This helps break down the grime gently without messing up the timber fibres. It’s nice if you have a deck made from delicate wood.
One thing to keep in mind is that after cleaning, you’ll want to wait 3 to 5 days before staining or oiling the deck. That drying time might be a bit annoying if you’re in a rush.
We also liked that they don’t just stop at cleaning. They also offer to stain or oil your deck afterwards to protect it and make it look fresh.
From our conversations with past customers, their service seems excellent. One person said their slimy, slippery deck looked brand new after they’d cleaned it.
On the downside, their cleaning process might take longer than quick, aggressive washes. So if you want a fast fix, this might not be it. But if you care about keeping your deck in good shape long term, their approach makes a lot of sense.
Highly recommend this team
“Excellent service, great job done with exceptional care of a fragile Oamaru stone seat. Our previous slimy slippery deck is no longer. It looks brand new, along with our outdoor table and chairs. Highly recommend this team. Thanks”

3. Amarco Exterior Cleaning

Amarco Exterior Cleaning uses a special water blasting method that’s strong enough to remove built-up dirt, but still gentle enough not to wreck your deck. It also gets the deck ready for sealing or staining later, which helps it last longer.
One thing we liked was that deck cleaning isn’t just a quick surface for them. It’s part of a bigger exterior clean, so they also tackle things like moss that can make decks slippery and unsafe.
That full-package approach means your outdoor space stays cleaner for longer, not just for a weekend.
We also noticed people love how easy they are to work with. Customers say they’re on time and flexible with schedule, even offering appointments outside normal hours if needed.
That said, they’re not the cheapest option out there. It seems you’re paying for quality and peace of mind, which is actually worth it, but something to think about if you’re trying to stick to a tight budget.
Great communication and took care in their work
“Completed work as agreed and to an exceptional standard. Great communication and took care in their work. I would recommend and will request their service again for future maintenance.”

They have been so friendly, thorough and reliable
“We had a very positive experience with Amarco cleaning our house, driveway and windows prior to selling our house. It looks fantastic and they have been so friendly, thorough and reliable. They carried out the work in a timely fashion, for when we needed it done. Would 100% recommend.”

4. Top Notch Pressure Washing

If you’re someone who’s had a deck ruined by aggressive water blasting in the past, Top Notch’s softwash method is good news for you. It uses low-pressure water combined with eco-friendly cleaners, so it’s a safer option for old or delicate decks.
Their versatility also impressed us. They adapt their cleaning process depending on your deck, if it’s natural timber, composite, or even PVC.
That’s important because using the wrong technique on certain materials can leave etching or strip away protective coats, which is expensive to fix.
We also appreciate how they make things easy for their customers. You don’t even need to be home during the cleaning, as long as any pre-clean prep is done.
They also offer digital communication and payments. It’s a small detail, but it really helps, especially for those who juggle busy workdays or family commitments.
After your deck’s cleaned, you can go a step further by having it sealed. Their premium resealing service not only makes the deck look better but also protects it from rain, UV, and general wear and tear. It’s a smart way to extend the life of your deck.
However, since softwashing is gentle, it might take a bit longer than regular pressure washing. So if you’re hoping for a super quick turnaround, you might need to factor in a bit more time.
I’m very pleased with his responsiveness and reliability
“Josh did an amazing job this week, water-blasting the pavement around our house, carport and driveway. I’m very pleased with his responsiveness and reliability in responding to my enquiry and getting the job done on time. I enquired on Wednesday evening; he visited the site midday on Thursday and did the job on Friday morning. By Friday afternoon, we were walking around admiring the cleanliness and freshness! I would highly recommend Top Notch Pressure Washing and would certainly engage their services in future.”
Emma Sale, Google review
One of the best companies I have ever dealt with
“Josh is an absolute professional, from quick response to my first enquiry to quote and explanation to start day and completion, not to mention the quality job by him and Jordan. One of the best companies I have ever dealt with.”

5. Jetmaxx

The best thing about Jetmaxx is their free on-site quotation. They don’t just give you a price. They come and check out your deck in person.
For us, this will give them a better idea of what actually needs to be done. They can also tell you the results you can expect right away. Some companies might try to upsell you on stuff you don’t need, so this kind of honesty is a plus.
Their cleaning method is hydro-blasting. It uses a strong water jet that blasts away dirt, moss, and algae without harsh chemicals or scrubbing that can damage the wood.
And if your deck is made of more delicate materials, don’t worry. They have a softer pressure option to make sure it gets cleaned gently but effectively.
We also got a few good reviews from past customers. One person said the team got rid of stubborn black stains on their decks that other companies couldn’t touch.
That said, their prices are a bit higher than the others we checked into. We think it’s fair, though, considering the quality of their service.
They are excellent communicators
“Jetmaxx are an awesome company to deal with. They are excellent communicators, and they did a thorough job of cleaning my windows and spraying the roof for moss. They are very friendly and went above and beyond what they had to do. I will definitely be using them again.”
Bev Bell, Google review
I’m thrilled with the results
“Vik has carried out a roof solar panel clean and treatment, and a fence waterblast today, and I’m thrilled with the results. Vik is respectful, professional, and takes his work very seriously – I will definitely have him back to do more work when it’s ready. His pricing is very reasonable, too! Thank you, Vik for your amazing work.”
