Auckland decks take a beating. Between humid summers, damp winters, and overhanging trees, your timber quickly collects moss, mould, dirt, and algae — creating slippery surfaces and a tired, greyed-out look.
Whether you’re hosting a BBQ in Howick, relaxing on a villa deck in Grey Lynn, or maintaining a rental in Papakura, a professional deck clean brings wood back to life and makes your outdoor area safe again.
At Metro Water Blasting, we provide specialised deck cleaning services across Auckland, using low-pressure techniques and safe treatments that won’t damage your timber.
Why Professional Deck Cleaning Matters in Auckland
Decks are exposed to everything the environment throws at them:
- 🌧️ Rain leads to moss, lichen, and mildew
- 🌿 Trees drop leaves and pollen that stain timber
- ☀️ UV exposure causes greying and drying
- 🪵 Moisture retention causes timber to rot prematurely
- ❗ Slippery decks become a serious fall hazard
Our cleaning process restores both appearance and safety, helping you enjoy your deck while extending its life.
