Exterior Cleaning Services in Lake Oswego, OR

Lake Oswego homes sit at the intersection of natural beauty and significant investment — and the Pacific Northwest climate is relentless about degrading exterior surfaces. The hillside neighborhoods, particularly Mountain Park and the areas surrounding Oswego Lake, are shaded by mature Douglas firs and Oregon oaks year-round. North-facing siding on these homes can turn visibly green within a single wet season, and roofs accumulate moss that — left untreated — shortens shingle lifespan by years.

We specialize in the kind of careful, low-pressure cleaning that Lake Oswego homes require. Cedar shake siding, Hardie plank, and painted wood all demand a different touch than vinyl — too much pressure can split cedar, lift caulk, or leave streaks on painted surfaces. Our soft wash process uses biodegradable cleaning solutions at low pressure to remove algae, mildew, and organic buildup without touching the surface aggressively.

Roof cleaning is another frequent request in Lake Oswego, especially for the older homes in the Westlake and Hallinan neighborhoods. Black streaks (Gloeocapsa magma algae) and moss both shorten shingle lifespan. We use the soft wash method recommended by major roofing manufacturers — no power washing on shingles, ever.

We work carefully, clean up thoroughly, and guarantee our results. For Lake Oswego properties, we bring the attention to detail the neighborhood deserves.
