Gutter Brightening in Seattle, WA
Green algae on siding is very common in Washington, especially on north walls and under trees. A soft wash kills it, and keeping plants trimmed back helps the walls dry between rains.
Near the coast, salt air leaves a film on siding, windows, screens and railings that dulls finishes and speeds up corrosion on metal. Regular rinsing and washing help protect them.

Gutter Brightening: frequently asked questions
How much does gutter brightening cost in Seattle, WA?

Do you use high pressure for gutter brightening?
Gutter Brightening is done with hand cleaning with a gutter cleaner. Low pressure and the right solution remove growth and dirt without damaging the surface, and the growth takes longer to come back.
Is gutter brightening safe for my plants and pets?
We pre-wet plants and lawns, keep cleaning solutions diluted to what the surface needs, and rinse landscaping again when we finish. Keep pets and children inside until surfaces are rinsed and dry.
How often should I schedule gutter brightening?
Every 1-2 years, often with a house wash. Shade, nearby trees, humidity and heavy traffic mean more frequent cleaning; sunny, dry spots can go longer. Our free cleaning frequency tool gives a recommendation for your climate.
What if it rains on the day?
Light rain doesn't stop most washing, but heavy rain, high wind, lightning and freezing temperatures do. If the weather isn't right, we reschedule at no charge. Our work is backed by a satisfaction guarantee.
