Seattle homeowners are increasingly seeking professional exterior cleaning services as the region’s notorious damp climate takes a toll on residential properties. According to recent data from the National Weather Service, Seattle averages 152 rainy days annually, creating ideal conditions for moss, algae, and mildew growth on home exteriors. This persistent moisture, combined with limited sunshine during winter months, has led to a 37% increase in exterior cleaning service requests over the past two years, according to local industry reports.
“What many Seattle homeowners don’t realize is that our climate accelerates exterior deterioration if left unchecked,” explains John Martino, a local home maintenance specialist. “Regular professional cleaning isn’t just about aesthetics—it’s preventative maintenance that can save thousands in potential repairs.”
The Evolution of Exterior Cleaning Services
Exterior maintenance in Seattle has evolved well beyond traditional pressure washing. Today’s comprehensive services include:
-
Soft roof washing to prevent shingle damage
-
Deionized water window cleaning to eliminate streaks without chemicals
-
Siding and driveway treatments to remove mold, algae, and grime
Roof cleaning, window washing, siding restoration, and driveway maintenance have emerged as the most requested services as spring approaches.

Seasonal Strategy for Maximum Impact
Experts recommend scheduling professional exterior cleanings in early spring, when winter’s toll is most evident, but before summer’s dry heat sets in.
