Questions, answered
How much does pressure washing cost in the Lake Stevens area?
Most residential projects land between $99 and $700 depending on size, surface and buildup. House washes are priced by square footage and stories; roofs by slope area and moss coverage; flatwork by area. You get an itemized, no-obligation quote before anything is booked.
Will you pressure wash my roof or soft wash it?
Our recommended method is a low-pressure soft wash — professional biocides that kill moss and algae at the root, then a full rinse. It is what ARMA and the shingle manufacturers call for; high pressure strips granules and voids most warranties. A lower-cost budget powder treatment is also available.
Are you licensed and insured?
Yes — Olson Landscaping Pro Wash LLC is licensed and carries general liability coverage. We provide a certificate of insurance for commercial, HOA and property-management work.
What areas do you serve?
We serve the Lake Stevens area and the wider Snohomish & North King County region — Lake Stevens, Everett, Marysville, Arlington, Granite Falls, Snohomish, Monroe, Mill Creek and nearby. Not sure if you're in range? Just ask.
Will the detergents hurt my plants or pets?
No. We pre-wet and rinse landscaping, use biodegradable products at safe dilutions, and follow a plant-protection protocol on every soft wash. Pets are fine once surfaces have dried.
