→ How much does house washing cost in Bellingham, WA?

Pacific Northwest siding does not really get dirty so much as it grows things. Mildew, algae and a green film take hold on the north and shaded elevations first, and by the time you notice it from the driveway it has usually been there a season or two.

We soft wash rather than pressure wash. That means low pressure and a cleaning solution that kills the growth at the root, instead of high pressure that strips the surface film off and leaves the organism behind to return within months. It is also the only safe method on vinyl, painted wood, cedar shingle, fiber cement and stucco – pressure forces water behind the siding and into the wall cavity, and that kind of damage does not show up until much later.

Every wash includes pre-wetting the plants and beds around the working area, tarping where it is needed, and a neutralising rinse when we are finished.

House washing starts at $399.

Our House Washing Services

Vinyl Siding
Cleaning

Vinyl is where pressure does the most hidden damage – it forces water up behind the laps and into the wall cavity. We soft wash it instead: low pressure, a solution that kills the algae at the root, then a clean rinse. The green film and streaking come off, and stay off longer.

Brick House
Washing

Brick and mortar hold moss and black spotting down in the joints, and aggressive pressure erodes the mortar itself. We clean masonry at low pressure with a treatment matched to the growth, so the brick comes back without the joints being chewed out.

Hardie Board
Cleaning

Hardie board and fiber cement are painted surfaces, and high pressure lifts the finish and shortens the life of the paint. Soft washing takes off the mildew and chalky film without touching the coating – which is what the manufacturer recommends in any case.

Frequently Asked House Washing Questions

Yes, and it is the safer option. Soft washing uses low pressure and a cleaning solution, so nothing is being forced behind vinyl laps, under cedar shingle or into a wall cavity. It is the method recommended for vinyl, painted wood, fiber cement and stucco. High-pressure washing on those surfaces can lift paint, drive water into the structure and leave damage that only shows up later.

Because soft washing kills the algae and mildew at the root rather than just rinsing the surface film off, most homes in Whatcom and Skagit County go a good deal longer between washes than they would after a straight pressure rinse. How long depends mostly on shade and exposure – a north elevation under trees will always come back sooner than a south wall in the open.

We pre-wet the plants and beds around the working area before we start, tarp where it is needed, and give everything a neutralising rinse when we are finished. Keep pets inside while we are working and they are fine to come back out once we have rinsed down.

Yes, and it is usually the sensible way to do it. We are already set up with ladders and water on site, so combining the siding with roof cleaning, gutter clearing or window cleaning in one visit saves you booking separate trips. Mention it when you ask for the quote and we will price it together.
