## Controlling Growth in the Damp Upper Skagit

Hamilton sits low along the Skagit River on Highway 20, a small upriver town where the air stays damp and the shade runs deep. For an exterior cleaner, that combination means one thing: growth. Moss on roofs, algae on siding, slick green film on every walkway.

Upriver homes benefit from a regular cleaning rhythm more than almost anywhere we work. Soft washing clears algae-heavy siding. Roof cleaning and moss and algae treatment protect shingles before growth lifts them. Gutter cleaning keeps systems flowing ahead of the heavy rains. Pressure washing de-slicks the walks and steps that get genuinely dangerous by midwinter.

We're about fifteen minutes up the highway, so Hamilton is close-to-home territory, and we're honest about what needs cleaning now versus what can wait a season.
