How It Works
What Is Gutter Brightening?
Gutter brightening is a specialized chemical treatment applied to the exterior face of your gutters to remove black tiger stripes caused by oxidation and roof runoff. This is completely different from gutter cleaning, which removes interior clogs.
Tiger stripes form when roof runoff bonds to the aluminum oxidation layer. Standard pressure washing can't break that bond - only the right chemical solution can. We apply our professional brightener, agitate, and rinse. Results are immediate.
