Safer footing, better looking timber
Deck Cleaning in Auckland
Shaded decks in Auckland hold moisture and grow moss faster than almost any other outdoor surface. We clean timber and composite decking at a pressure that lifts grime without splintering boards or stripping stain.

Our process
What happens on the day
Timber condition check
We check board condition and any soft or splintering spots before deciding on pressure and technique.
Moss and mould treatment
A cleaning solution breaks down moss and mould growth between boards, where a blast alone can't fully reach.
Low-to-medium pressure wash
We wash with the grain at a pressure suited to your timber, avoiding the fuzzing or splintering that comes from over-blasting.
Drying check
We confirm the deck is drying evenly before we finish, flagging any boards that may need attention or resealing.
Why it's worth it
The benefits of professional deck cleaning
Safer underfoot
Removing moss and algae buildup between boards significantly reduces slip risk for family and guests.
Extends deck life
Clearing trapped moisture and organic growth reduces rot risk in untreated or ageing timber.
Deck ready for staining
A properly cleaned deck is the right starting point before any re-stain or reseal, so the coating adheres properly.
FAQ
Deck Cleaning questions
Used carelessly, yes — over-blasting timber is a common cause of splintered, 'fuzzy' decking. We match pressure to your timber's condition and always test an inconspicuous area first.
Yes, composite decking is cleaned at a lower pressure with a suitable detergent, since it responds differently to moss and grime than timber.
We recommend letting the deck dry out fully — usually a few dry days — before applying any stain or sealant, so it bonds properly to the timber.
