We all know that cleaning the inside of your gutters and downspouts is very important, but what about the stains on the outside? Many times, a home owner gets their house washed and the gutters remain stained because this type of staining is often impervious to typical house wash solutions. We often recommend our gutter whitening service to those who have stubborn black streaks on their gutters.
