Exterior Cleaning Service Areas Thurston, Mason & Lewis Counties

Veteran-owned and based in Olympia, Dowers Power Wash LLC brings professional pressure washing, soft washing, roof cleaning, and moss removal to homes and businesses across the South Sound. Same-day response. Experience you can trust.

From our home base in Olympia, our team covers the communities of Thurston County and reaches into Mason and Lewis counties - the full stretch of the South Sound where Pacific Northwest rain, shade, and tree cover keep moss, algae, and grime working year-round on every roof, driveway, and siding panel. Wherever you are on this page, the service is the same: licensed and insured (License #DOWERPW784JG), eco-friendly biodegradable cleaning solutions, and low-pressure soft washing that protects your surfaces while restoring them.

  • Olympia, Washington

Our hometown. From the tree-heavy streets of South Capitol to the waterfront neighborhoods off the West Bay, Olympia roofs and driveways live under some of the densest evergreen canopy in the county — and we've cleaned under most of it.

Between the lake neighborhoods around Hicks, Pattison, and Long Lake and the newer developments of Hawks Prairie and Meridian Campus, Lacey homes fight shade-driven moss on one end of town and fast algae streaking on the other.

Tumwater's mix of established neighborhoods off Capitol Boulevard and newer construction toward the airport gives us a bit of everything — older roofs carrying years of moss, and newer surfaces where early treatment keeps them clean for good.

Centralia, WashingtonDown the I-5 corridor in Lewis County, Centralia's historic housing stock — including some of the oldest homes we work on — needs the gentle touch of soft washing rather than aggressive pressure. We serve Centralia with the full residential and commercial lineup, from roof and gutter cleaning to storefront and building washing downtown.

  • Shelton, Washington

Mason County's timber town sits deep in the trees, and Shelton roofs show it — fir needles in every valley and moss on every north slope. We make the trip regularly for roof cleaning, moss treatment, house washing, and gutter service throughout Shelton and the Oakland Bay area.
