About 2 years ago this customer had new 6 inch gutters and 3 x 4 in. downspouts installed on their home in Reston, VA. Several corners were cut during the installation process and the gutter constantly were overflowing. So much so, that they turned black and had several other signs of damage.
We flushed the gutter system out, wiped the gutters down with a Simple Green product, and installed MasterShield. Now, the homeowner will now never have to clean his gutters, underground drains, or downspouts again. The water will no longer cascade over the gutter system and create waterfalls so the home will overall be a more comfortable and dry place.
