Rendered walls
Acrylic and cement render cleaned without etching the surface.
Gentle, low-pressure house washing that lifts mould, grime and pollution from your exterior walls, eaves and gutters — without blasting paint or damaging delicate surfaces.

House washing is the careful, low-pressure cleaning of a home's exterior — render, brickwork, weatherboards, eaves, fascia and gutters. Unlike flat surfaces, walls are usually cleaned with soft washing: a biodegradable detergent is applied, given time to break down mould and grime, then rinsed away at low pressure. This protects paint and delicate finishes while still removing the green and black staining that builds up in Sydney's humid, shaded conditions.
The benefit goes beyond appearance. Mould and algae on walls hold moisture against the surface, which can accelerate paint breakdown and staining. Regular house washing extends the life of your exterior finish and keeps the home looking maintained. We tailor the method to the surface — render and brick take a detergent soft wash, while tougher areas like concrete window sills can handle a little more pressure. Every job is owner-operated by Tommy, so the care and communication are consistent from quote to finish.

No. We use a soft-wash method — biodegradable detergent and low-pressure rinsing — specifically because high pressure can strip paint and damage render. We adjust the approach for each surface type.
Most Sydney homes benefit from a house wash every 12–18 months, though shaded, tree-lined properties may need it more often. If you can see green or black staining on the walls, it's time.
A standard house wash covers walls, eaves, fascia and gutters. Heavier brick cleaning and acid washing is a separate service — we're happy to combine both if you'd like, just mention it when you request your quote.
We use biodegradable cleaning solutions and rinse thoroughly. We'll also discuss any plants or areas you'd like us to be mindful of before we start.
