Warm humid weather creates mouldy houses. It covers the walls slowly enough that you don’t quite notice it happening, and fast enough that you can’t quite believe that everything is mouldy again. Welcome to another Queensland summer. This house in Palmwoods is a classic example. The green mould is on all the walls, eaves and gutters. And black mould is growing on the metal roof. We tackled it with a full external house clean: roof, gutters, solar panels, walls, eaves – the lot. And they came up looking great. There’s nothing quite like the feeling you get from a just pressure cleaned house.
