Pressure and Soft Washing

We match the technique to the material: soft washing for delicate surfaces like roofing and siding, pressure washing for concrete and masonry.

Dirt, mold, mildew and algae build up fast on exterior surfaces in the mountains, where shade, humidity and tree cover keep things damp. Washing them away is simple in theory, but the wrong pressure on the wrong surface does real damage.

That is why we use two methods. Soft washing relies on low pressure and a cleaning solution that breaks down growth at the source, which makes it the right choice for roofing, siding and other delicate surfaces. Pressure washing uses water pressure to lift dirt from hard, durable surfaces like concrete and masonry. Each job gets the method that suits its material.

What we wash

Siding with green, black or gray buildup
Roofs with algae, moss or dark streaking
Decks and exterior wood that look dingy or slick
Concrete driveways, patios and walkways
Pavers, stone and masonry before sealing

How we approach it

Identify the surface
What the surface is made of decides how much pressure it can take, so we start there.
Choose the method
Soft washing for roofing and siding, pressure washing for concrete and masonry.
Clean and rinse
We remove dirt, mold and mildew buildup and rinse the surface thoroughly.

Washing is often the first step before sealing or staining. If your surface also needs protection, see concrete sealing, paver sealing or wood deck staining.

Common questions

What is the difference between pressure washing and soft washing?

Pressure washing uses higher water pressure to blast dirt off durable surfaces. Soft washing uses low pressure with a cleaning solution that breaks down mold, mildew and algae, so it is gentler on roofing, siding and other surfaces that high pressure can damage.

Will pressure washing damage my siding?

It can. High pressure can force water behind siding and mark softer surfaces. That is why we soft wash siding and roofing and save pressure washing for hard surfaces.
