How to Clean a Timber Deck in Wellington Without Ruining It

Timber decks in Wellington stay damp. North-facing boards grow algae; shaded courtyards go black and slippery. High-pressure blasting raises the grain and shortens the life of the board.

Soft wash: Low-pressure detergent, dwell time, then a thorough rinse. Gardens get covered first. Small decks start from around $180.

Composite and concrete patios: Same visit, different method. Tell us which surface you have.

How often: Shaded decks often need a wash every 12 months. Open, sunny decks can stretch to 18.

With a house wash: If the cladding is due too, book both. One crew, one visit, and the outdoor living area matches the rest of the exterior.
