House washing that doesn't strip the paint
Soft-wash for render, weatherboard and painted brick across the Gold Coast to Byron Bay corridor. Mould and mildew off, your paint job left alone.
Rendered double-storey home with one wall freshly soft-washed showing bright white render next to the dirty grey side — placeholder until real photos loadThe mould you see on the south side of a coastal house isn’t a paint problem. It’s biological growth on top of the paint, fed by humidity, shade and salt air. Soft-wash detergent breaks it down to the root and a low-pressure rinse takes it off. The paint stays where it was.
The mistake people make is putting a turbo nozzle on a render wall and chipping off little flakes of paint, render and undercoat all at once. That makes the wall look better for two months and then exposes the substrate to weather. We’d rather take a bit longer and leave you with a wall that’s clean AND intact.
Most one-storey houses in the Tweed and Murwillumbah take half a day. Larger two-storey homes are a full day. We work top-down: roof clean first if you’ve booked one, then the upper-storey walls, then everything underneath. The gutters and eaves get a wash at the same time, from the outside; if you want the inside of the gutters cleared out, that’s our gutter-cleaning service and best done in the same visit.
We don’t pressure-clean Colorbond cladding with a turbo nozzle; the wrong detergent and the wrong pressure will chalk the coating. The same goes for old hand-stencilled render and any heritage finishes. If we’re not sure, we test a small panel first.

A recent job
"Will high pressure crack my render or blow my window seals?"
Surfers Paradise, QLD · Exterior soft-wash, Surfers Paradise canal townhouse
The brief
Three-storey canal-front townhouse with render and rendered-block walls. The waterline-facing elevation had gone grey-green with salt and mould, and the body corporate wanted it presentable before a unit went to market. Owner was nervous about pressure cleaning near the large windows and the rendered parapet.
What we found
Mould and salt film were surface only — the render coating underneath was sound, no blistering or hollow spots. A little efflorescence at the base of the canal-side wall from constant moisture, which a wash won't permanently fix but does clean back. Window seals were intact.
What we did
Masked nothing we didn't need to, closed all openings, and worked off a platform for the upper level. Soft-wash detergent matched to the render, dwelled to kill the mould at the root, then a low-pressure top-down rinse — no high-pressure anywhere near the glass or the render. Hand-detailed the entry and the balustrades.
Result
Walls came back to their original off-white in a day. We flagged the efflorescence in writing so the owner understood it's a moisture symptom that'll return, not something the wash failed to remove. Unit photographed the following week.
FAQ
House Washing questions, answered
Will the wash take my paint off?
Not when it's done as a soft-wash with the right detergent at low pressure. The mistake is putting a turbo nozzle on a render wall — that chips off paint, undercoat and a flake of the substrate with it. The wall looks clean for two months then exposes the substrate to weather. We use the right detergent to break the mould at the root and a low-pressure rinse to take it away. Paint stays where it was.
What about the windows and the deck — do those get cleaned too?
Window frames yes; window glass no (that's a separate trade with the right gear for streak-free glass). Decks we can soft-wash at the same time if the timber's in good condition — usually a slight pressure reduction for hardwoods and a much gentler approach for softwoods. Most decks want an oil or stain refresh afterwards, which we don't apply but can recommend.
How long does a soft-wash last on this coast?
Roughly eighteen months to two years on the coastal strip, two to three years inland. Salt air, shade and tree cover all speed up regrowth. A quick yearly maintenance wash is much cheaper than letting it go five years and needing a full job — and it keeps the paint protected for longer.
