House Washing for Coastal WA Homes
Coastal house washing that protects as well as cleans. Soft washing removes salt and kills mould and algae at the source, safely, without the damage high-pressure blasting does to render, paint and roofs. Part of our pressure washing & cleaning service.
Why coastal homes need regular washing
Inland, washing a house is mostly cosmetic. On the coast it's protective. Salt is constantly landing on every surface, and unlike ordinary dirt it's corrosive. It draws moisture, breaks down paint bonds, feeds metal corrosion and soaks into render. The catch is that salt is largely invisible; your house doesn't look dirty, so it's easy to leave. By the time you see the damage, peeling paint, tea-stained metal, bubbling render, the salt has been working for a while. Regular washing removes it before any of that starts.
How we wash coastal homes
Assess the surfaces
We identify which surfaces need soft washing, which can handle higher pressure, and any staining (salt, mould, bore water) that needs specific treatment.
Soft wash the house
Low pressure plus cleaning solutions that kill mould, algae and lichen at the source, safe on render, paint, roofs and timber, and the result lasts.
Hard surfaces
Driveways, paving and hard surfaces cleaned at appropriate pressure for the material.
Recommend a rhythm
We advise on the right washing frequency for your exposure, so salt never accumulates between visits.
How we work with you
Honest advice, not an upsell.
We tell you what your home actually needs, and what it doesn't. If something can wait, we'll say so. We'd rather build a long relationship than win one oversized job.
We treat the cause, not just the surface.
Most coastal problems come back because they were patched, not fixed. We work out what's actually driving the damage (salt, moisture, corrosion) and deal with that, so the repair lasts.
A proper look before any quote.
We assess your property in person before we put a number on anything. It's free, there's no obligation, and it's the only honest way to quote coastal work, because every home is exposed differently.
The coast is all we do.
We're not generalists who also do beach houses. Coastal salt, corrosion and weather are our entire focus, which is why we catch the things others miss.
Built for the coast.
Anyone can paint a wall or wash a house. The coast is different: salt gets into render, corrodes metal from the inside, and breaks down coatings from underneath, and it never stops. Treating coastal problems like inland ones is why so much work fails early.
Salt Coast exists for exactly this. We diagnose before we treat, use methods and materials suited to coastal exposure, and build ongoing maintenance relationships rather than one-off jobs. That's how a coastal home stays sound instead of lurching from one repair to the next.
Keep your home ahead of the coast, not chasing it.
You wait for paint to peel, render to bubble, metal to rust, then react to damage that's been spreading for months.
We catch it before it shows, while every fix is still small, cheap and quick, and you never lift a finger to manage it.
Fremantle based. Dawesville to Two Rocks.
We service the Western Australian coastal corridor from Dawesville in the south to Two Rocks in the north, from the beachfront to roughly 10km inland. House Washing is available across the full service area.

FAQs
How often should I wash my coastal home?
Generally two to four times a year, against about once a year inland, because salt lands constantly and damages paint, render and metal the longer it sits. The closer to open surf, the more often. It's preventive maintenance, not a response to a dirty-looking house, since the most damaging thing, salt, is largely invisible.
Is soft washing or pressure washing better for my house?
For most of a house, soft washing. It uses low pressure and cleaning solutions that kill mould and algae at the source, so it's safe on render, paint, roofs and timber and the result lasts. High pressure suits hard surfaces like driveways but can damage softer building materials.
Soft washing vs pressure washing: which is right for your home
Why wash my house if it doesn't look dirty?
Because the most damaging thing on coastal walls, salt, is largely invisible. It doesn't make a house look grubby, but it draws moisture, corrodes metal and breaks down paint. By the time visible problems appear, the salt has been doing damage for a while. Washing removes it before that starts.
Can you remove the orange bore water stains?
Yes. Orange staining from iron in bore water needs a dedicated rust-removing product matched to the surface. Ordinary washing won't shift it. We treat the staining and can advise on preventing it, usually by keeping reticulation spray off the walls and fences.

Will washing damage my roof or render?
Not the way we do it. We soft wash roofs and render at low pressure, which avoids the cracking, stripping and dislodged pointing that high-pressure blasting can cause. The method is matched to each surface so cleaning never damages the home.
