Clean rain gutters are an integral part of a home’s exterior. Old, damaged or defective rain gutters can cause a lot of damage. When a gutter clogs, the water is not diverted properly and overflows into either the house or foundation. This can cause wood rot, foundation problems and landscaping erosion. In addition to damage to your home, a rain gutter clogged with soggy leaves and debris is the perfect breeding ground for mold and mildew, as well as mosquitoes and other pests.
