Exterior Cleaning in Blaine, WA

Spotless Heights Exterior Cleaning provides gutter cleaning, roof soft-washing & moss removal, pressure washing, window cleaning, solar panel cleaning, and exterior soft washing across Blaine, WA and all of Whatcom County — owner-operated, eco-friendly, licensed and insured.

Blaine sits at the US–Canada border on Semiahmoo Bay, where salt air and steady marine humidity keep moss, algae, and lichen aggressive on roofs and siding all year. Coastal homes here need exterior cleaning more often than inland ones — the marine layer never really lets a north slope dry out.

What Blaine Homes Deal With

• Salt-laden marine air accelerates algae and “black streak” growth on roofs — a soft wash kills it at the root instead of just rinsing it off.
• Waterfront and bluff homes catch wind-driven grit and salt film on windows and siding; our organic wash leaves them streak-free.
• Semiahmoo’s larger homes and steep rooflines are exactly where safe, insured, low-pressure roof work pays off.

We regularly serve Semiahmoo, Birch Point, Blaine Harbor, and downtown Blaine. Blaine and Birch Bay are a regular part of our north-county route — call for a free quote.
