## Cleaning Whatcom Homes from the Bay to the Border

Whatcom County stretches from Bellingham Bay to the Canadian border, and each of its towns brings different washing work: Bellingham's craftsman neighborhoods under big trees, Lynden's famously well-kept homes and dairy farms, and the salt-exposed shoreline of Blaine, Birch Bay, and Semiahmoo.

The common enemy is the north-coast climate: long damp seasons that green up siding, mossy roofs under mature trees, and salt film wherever the sea reaches. Soft washing for the old and delicate, roof cleaning and moss and algae treatment county-wide, gutter cleaning that keeps pace with the trees, window cleaning for coastal glass, and pressure washing for concrete when hard surfaces need it.

Wherever you are in the county, quotes are free, written, and honest about what actually needs cleaning.
