Pressure washing in Portland, OR
Portland's wet climate means moss, algae, and grime build up fast on driveways, patios, and walkways. Our professional pressure washing gets them looking clean again — fast.
Why Portland driveways need pressure washing
If you've lived in the Portland area for any length of time, you know what the PNW climate does to outdoor surfaces. Between October and May, your driveway, patio, and walkways barely dry out — and that constant moisture is exactly what moss and algae need to get established. Add in fallen leaves, tree sap, and the occasional oil drip from a parked car, and most Portland driveways look noticeably worse after just a year or two without cleaning.
Pressure washing isn't just about appearances. Moss-covered concrete is a genuine slip hazard, especially in wet weather. Organic buildup also accelerates surface degradation over time, meaning regular cleaning can actually extend the life of your driveway or patio. Think of it as low-cost maintenance that protects a much bigger investment.
We serve homeowners throughout Portland, Tigard, Lake Oswego, Beaverton, and the surrounding metro area. Whether you need a quick driveway refresh or a full exterior surface clean before putting your house on the market, we're happy to take a look and give you a straight quote.

Our pressure washing process
Surface Assessment
We inspect the surface to identify stain types, existing damage, and the right pressure and nozzle settings for your specific material.
Pre-Treatment
We apply a biodegradable cleaning solution to break down oil, moss, and organic buildup before any pressure is applied.
Pressure Washing
Using commercial-grade equipment, we work systematically across the surface — typically 2,000–3,500 PSI depending on the material.
Detail Edges & Joints
We hit expansion joints, edges, and corners by hand to make sure nothing gets missed.
Final Rinse & Inspection
A clean rinse removes all loosened debris. We walk the surface with you to confirm you're happy before we pack up.

Frequently asked questions
How often should I pressure wash my driveway in Portland?
Because of Portland's wet climate and the amount of organic growth (moss, algae, mildew), most driveways benefit from cleaning once a year — typically in spring to clear winter buildup, or fall before the rainy season. Heavily shaded driveways may need it twice a year.
Will pressure washing damage my concrete?
When done correctly, no. We match the pressure and nozzle to the surface. Older or cracked concrete is inspected first and we adjust accordingly. We never use excessive pressure that could etch or erode the surface.
Can you remove black moss stains from my driveway?
Yes — moss and the black staining it leaves are common in Portland. Our pre-treatment solution kills the moss at the root, and the pressure washing clears the surface. Some older, deeply penetrated stains may lighten but not fully disappear.
How long does driveway pressure washing take?
A standard single-car driveway takes 45–90 minutes. Larger driveways, patios, or surfaces with heavy staining take longer. We'll give you a time estimate when we quote the job.
