Power Washing in Redmond, WA

Western Washington's wet climate creates some of the heaviest moss and algae growth conditions in the country, particularly on roofs and driveways in the Seattle and Tacoma areas. Late summer — July through September — is the ideal scheduling window in western Washington, when surfaces can be properly treated and allowed to dry. Moss treatment in Washington is considered preventive maintenance, not just cosmetic. Untreated moss holds moisture and can shorten asphalt shingle life by ten or more years.
