Pressure WashingIn Gresham.

Gresham’s housing stock leans heavily post-war and mid-century, and driveways and siding that have gone years without cleaning tend to build up more grime than homeowners expect from just “a little dirt.”

Pricing depends mainly on square footage, surface type, and how much buildup there is to remove — a driveway with years of moss growth takes more time than a lightly dirty one. Oregon’s wet climate means moss and algae buildup is a bigger factor here than in drier parts of the country, which is part of why pressure washing tends to matter more for PNW homeowners than a one-time cosmetic fix.
