Clear Skies Gutter and Window Cleaning has serviced hundreds of homes, storefronts, office buildings, construction sites, and high-rises in the greater Seattle areas. - Clear Skies also offers roof treatments to remove moss and lichens from getting in and under your shingles. This can lengthen the life of your roof. After blowing the loose debris off we put a zinc treatment and clean the interior of the gutters. We hope to be you regular Window and Gutter cleaners.
