How to Keep Mould Off Your Home’s Exterior in Brisbane’s Humid Climate

Living near the coast means plenty of fresh air — and plenty of mould. Homes around Wynnum, Manly, and Lota are especially prone thanks to salty air and humidity. I’ve spent decades removing mould from painted walls, decks, and roofs, so here’s how you can keep it from coming back.

💧 Start with a Proper Soft Wash

A professional soft wash removes existing mould spores safely. High-pressure blasting only spreads them around. My cleaning solution neutralises the source and slows regrowth for months.

🌿 Trim Plants and Improve Airflow

Overhanging gardens trap moisture against walls. Give shrubs and vines some space to let your exterior dry quicker — especially on the shaded side of homes in Tingalpa and Carindale.

☀️ Regular Maintenance is Key

Once or twice a year, rinse down your walls or book a quick maintenance wash. It’s cheaper than a full repaint — see why washing beats repainting.
