House Washing

Bring your siding back without damaging it

Our damp, shaded climate is perfect for mildew, algae, and mold — especially on north-facing walls and under eaves that rarely see direct sun. Add road dust, pollen, cobwebs, and oxidation, and even a newer home starts to look tired and dingy.

High-pressure washing might seem faster, but on siding it’s risky: it can crack or dent panels, force water behind the cladding, and strip paint. Soft washing is the safe alternative — low pressure plus a cleaning solution that kills organic growth at the source, so your siding stays clean for months, not days.

We clean vinyl, fiber cement (Hardie), LP SmartSide, cedar and wood, stucco, and brick, adjusting our approach to each material.

A soft wash makes a bigger difference than paint

FAQ

House Washing questions, answered

What’s the difference between soft washing and pressure washing?

Pressure washing relies on high-force water and is appropriate for hard surfaces like concrete. Soft washing uses low pressure plus a cleaning solution and is the safe choice for siding, which can be damaged by high pressure.

Can you clean vinyl, Hardie, cedar, and stucco?

Yes. We adjust our solution strength and technique for each material, from vinyl and fiber cement to natural wood, stucco, and brick.

Will house washing damage my plants?

We pre-wet and rinse landscaping and use plant-safe solutions. When done correctly, house washing is safe for your yard, pets, and family.

How often should I have my house washed?

Most homes in Southwest Washington look best with a wash every 1–2 years. Heavily shaded or north-facing homes may benefit from annual cleaning.

Do I need to be home during the service?

Not necessarily, as long as we have access to water and the exterior. We’ll confirm details with you when we schedule.
