The answer to 'gutter mildew' is that it is a common problem caused by the buildup of organic matter, such as leaves, twigs, and debris, in gutters. This creates a damp, dark environment that allows mold and mildew to thrive. Symptoms of gutter mildew include a slimy, discolored appearance and a musty odor. To address this issue, it's important to regularly clean and maintain your gutters.
Homeowners can often handle light gutter cleaning and mildew removal as a DIY project, but more extensive or recurring problems may require the expertise of a professional gutter cleaning service. Regular gutter cleaning, using a gutter brush or high-pressure water, can help prevent mildew buildup. For severe cases, a professional may need to use specialized cleaning solutions or replace damaged gutters.
