Local gutter brightening for Petworth, DC
Humid summers in District of Columbia grow green algae and black mildew on the shaded sides of homes, especially on vinyl and painted wood. A soft wash kills the growth rather than just knocking it off, so the siding stays clean longer.

Gutter Brightening: frequently asked questions
How much does gutter brightening cost in Petworth, DC?
Gutter Brightening typically costs $150-$400 for a typical home, and usually takes 1-3 hours. The exact price depends on the size and condition, and you get it before any work starts. Call (555) 010-0000 for a free quote.
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.
