Grime, mould and weather build-up don’t stay on the roof — they creep down the walls, decks and paths too, gradually dulling even a well-kept home’s appearance. Left alone, this build-up doesn’t just look tired; it holds moisture against cladding and painted surfaces, which over time can affect the material underneath in the same way untreated moss affects a roof.
Our residential house wash lifts years of dirt and organic growth from your exterior surfaces, restoring your home’s kerb appeal without the risk of damage that comes with amateur pressure washing. It’s the finishing touch that makes a treated roof and a clean home match — so the whole property looks cared for, not just the roofline.
Dirt and organic growth don’t need much encouragement to take hold on an exterior wall — and once they do, they only get harder to shift.
walls facing away from the sun stay damp, letting mould and algae take hold.
wind-driven dirt, pollen and organic debris settle on cladding and slowly build up over time.
the longer exterior grime is left, the more it bonds to the surface, making it harder to remove.
Left unchecked, this build-up doesn’t just dull your home’s appearance — it sets the stage for bigger, costlier problems down the line.
Rather than a single blanket wash, we treat your home’s exterior as a two-part process — matching the method to the surface, then finishing with care.
Every home is different, so we assess your cladding type — timber, brick, render, vinyl or Colorsteel — and select the right low-pressure approach for that surface, rather than using a one-size-fits-all wash.
We apply a gentle, low-pressure wash that lifts dirt, mould and algae without forcing water behind cladding or stripping paint and coatings, leaving your home’s exterior clean without the damage risk of amateur pressure washing.
our low-pressure method won’t strip paint, force water behind cladding, or damage timber, render or brick the way amateur pressure washing can.
a proper low-pressure wash lifts grime and organic growth at the root, so your home stays cleaner for longer, not just for a week.
