Toowoomba City & suburbs

Exactly the climate mould, algae and lichen want. $20 million public liability, Working at Heights certified, police-checked crew and a documented SWMS, signed by every worker and reviewed annually.
Why us here
We work Middle Ridge regularly, so a quote rarely means a long wait. What matters most is method: concrete, pavers and brickwork take pressure cleaning; render, paint, weatherboard and Colorbond take soft washing, where the treatment kills mould and lichen at the root rather than blasting the surface off. Roofs get a soft wash by default, or a controlled high-pressure surface clean where the roof suits it. Firm price before we start, photos when it is done.

Red Ferrosol (Ruthven–Middle Ridge)
Red Ferrosol here: fine iron-rich clay that soaks into bare concrete instead of sitting on top, which is why hosing a stained driveway does nothing. Lifting it needs a surface cleaner; sealing afterwards stops it going back in.
This is the high southern end of the city — coldest, dampest, longest dew. Exactly the climate mould, algae and lichen want.
Middle Ridge is older than most people realise — it ran its own shire council from 1880 to 1917 — and the Great Dividing Range itself passes through the suburb, which is why the western side sits up around 660m while the eastern side falls away toward 420m. That drop matters for us: the high western streets hold dew longest and green up fastest, while the eastern fall gets more sun and dries earlier.
Through the year
What the walls and concrete are telling you
Green or black film on the south and east walls is mould, not dirt — it needs a treatment, not a blast. Grey-green crust on the roof is lichen, bonded into the tile. Water spilling over a gutter edge is going into the fascia. A driveway that has changed colour is this ground at work. Streaky glass is mineral film. A solar array quietly making less than it used to is usually just soiled.
Most often in Middle Ridge: roof cleaning, exterior house washing, soft washing. Also gutter cleaning, driveway and path cleaning, window cleaning. Book several in one visit — cheaper, and the order matters: roof, gutters, walls, then windows.
