Deck and fence cleaning that restores tired timber
Decks and fences take a beating from the weather. Rather than just blasting them, we treat the timber with our own bleach-free cleaning solution that lifts out the grey, green and grime and genuinely restores the wood — ready to enjoy, or perfectly prepped for oil or stain.
Deck & fence cleaning
Restored, not just blasted
High pressure on its own can bruise and furr up timber. We use our own bleach-free cleaning solution that draws mould, algae and weather-grey out of the wood and brings its natural colour back — properly restoring the timber rather than just washing over it.
Why bleach-free matters
Bleach can dry out and damage timber, harm the plants around it, and only mask growth for a while. Our own solution does the job properly and safely, so the result lasts and your garden stays happy.
Prepped for coating
Planning to re-oil or stain? A clean, sound surface is essential for a good finish, so we clean the timber back properly and your coating goes on evenly and lasts.
What's included

What we clean
Decks, fences and outdoor timber
If it's timber and it's gone grey, green or grubby, we can bring it back.
Timber turns silvery-grey and grows mould and algae as it weathers — especially on the shaded, south-facing side. Our bleach-free solution lifts that out of the grain and brings the natural warmth of the wood back, without the bruising and furring a high-pressure blast can leave behind.
It works on most outdoor timber, from pine to hardwoods like kwila and vitex. If you're planning to re-oil or stain, a proper clean is the best prep there is — the coating goes on evenly and lasts far longer on sound, clean wood. For keeping it looking good between cleans, see our guide to spray-and-leave deck maintenance.
What we clean
- Timber and composite decking
- Fences, gates and screens
- Pergolas, balustrades and handrails
- Outdoor furniture and steps
- Prep before oiling or staining
Safer underfoot
Less slip, more enjoyment
That green film on a shaded deck isn't just unsightly — it's slippery, and it gets dangerous in the wet. Clearing the mould and algae out makes the surface safer to walk on and far nicer to use, right through the cooler months when decks usually get neglected.
How we price it
Deck and fence cleaning is priced by the square metre, so you pay for the size of the actual job. The condition of the timber and access play a part too. The easiest way to get a figure is a quick free quote — just send a few photos and measurements.

Deck & fence cleaning FAQs
Can you bring back grey, weathered timber?
Usually, yes. Most of the grey is weathered surface fibre and ingrained mould and algae. Our bleach-free solution draws that out and brings the natural colour of the wood back — short of timber that's actually rotten or badly damaged, the difference is often dramatic.
Do you use bleach on decks and fences?
No. Bleach can dry out and damage timber, harm the plants around it, and only masks the growth for a while. We use our own bleach-free cleaning solution that does the job properly and lasts, and is kinder to your garden.
Can I oil or stain the deck afterwards?
Yes — and a proper clean is the best prep you can give it. We clean the timber back to a sound, even surface so your oil or stain soaks in evenly and lasts. Just let the timber dry out fully first; we'll tell you how long to leave it.
Will cleaning make my deck less slippery?
Yes. Most of the slip on a deck comes from the mould and algae growing on the surface. Lifting that off makes it much safer underfoot, especially through the damp, cooler months.
How often should I clean my deck or fence?
Most Auckland decks benefit from a clean once a year, and shaded or bush-surrounded ones a little more often. A spray-and-leave treatment between cleans keeps the growth from coming back — see our deck maintenance guide.
