I had my gutter guards installed in 2009. Recently they began to leak profusely. We called gutter guys and they came out and went up to look. Neil and Carlos started asking questions and it soon became apparent that the problem was that a new roof had been installed and the roofers left some of their garbage in the gutters. This is obviously a common problem. The roofers usually nail the shingles to the gutter guard. Fortunately these roofers did not nail the gutter guard down. Neil and Carlos were unbelievably nice and cleaned the gutter, run water through it and cleaned up. This was 4 years after the installation and they fixed a problem they had not even caused. Use this company – they are good people.
