A quick clean from Wash NZ made the whole space feel brighter and more cared for.
Is your deck slippery, grimy, or just looking tired?
We wash timber decks to remove mould, dirt, and buildup without damage. You’ll get a safer, more inviting outdoor area you can enjoy without worry. A clean deck transforms how your outdoor space feels — it’s one of the best ways to bring life back to your backyard.
Services We Offer
Soft Wash for Timber Decks
We remove dirt and mildew gently, preserving your timber while bringing out its natural colour. The results are always satisfying.
Slippery Surface Treatment
We clear away algae and grime that make decks dangerous. It’s great knowing you can walk barefoot without worrying.
Spa Area Deck Cleaning
We take extra care around spa areas to remove buildup and ensure the space is clean, safe, and ready to enjoy.
