I had new gutters and gutter helmet installed three years ago. I used a professional company, paid a decent price, and thought I could relax about one thing on my older home. With heavy rains this spring, I started to see water damage inside my home in my dining room (on an outside wall). I called a trusted roofer thinking it was the roof but only to find out it was the gutters/gutter helmet. He showed me by using a hose as we watched the water fly over the gutters. The gutter helmet didn't allow the water to go into the gutter but behind it and over it. It damaged the siding, wore away the mortar on the bricks, and damaged a large window outside. Inside I had to have my entire wall tore out. Base plate, insulation, paneling, flooring, all had to be replaced. I had to deal with mold and mildew as well. When I called them to come and look at it, they came, they argued with me until my carpenter showed up. At that point, they finally agreed to do as I asked and rehung the gutter, along with a spacer behind it (as I had requested in the beginning), fixed a bad corner that clearly wasn't coped in or sealed correctly, all while still stating their product worked. Doing a water test with the hose, when I got home, after they said it was fixed, the water still did not go into the gutter! They never checked! We ended up tearing off the gutter helmet and will probably have to rehang the gutter higher and put on new screening to keep the leaves out. I will have to tear off the gutter helmet other places on the house and rehang the gutter as well before more damage occurs. I thought they were experts. They were not. This is a cautionary tail for others. Do not think that just because they have an advertised company and can talk a big talk that they know what they are doing. They clearly did not. This was an expensive lesson to learn. Please be warned. read more
