We recommend a service professional inspect your gutter system twice a year for possible damage or clogs. The moment you notice an overflowing section, avoid the common problems a faulty gutter system can cause, and call us for service.
If your gutters are sagging in most cases what we do is install 6" x 1/4" threaded lag bolts in ferrells with washers at the key locations in place of the spike and ferrells that continues to come loose and fall out. The threaded lag bolt pulls the gutter up nice and snug against the fascia board of your home. This is an excellent method of repair!
