Most homeowners on Long Island should have their gutters cleaned at least twice a year, once in the spring after pollen and seed pods drop and once in the fall after the leaves come down. If you have large trees close to your roofline you may need service more often. Clogged gutters back up fast and when they do the water has nowhere to go except over the edge or back under your roofing, which leads to fascia rot, foundation issues, and costly repairs. Power Washing Pro keeps that from happening.
