Found these guys at the Wilson County Fair, and looked over their product. They offered a free estimate and consultation, so we took advantage. They came out, spent a little time looking over our existing gutters, and making recommendations. What we liked was not only did they install product to help our constantly clogging gutters(we have several HUGE oak and maple trees in our backyard, and are backed up to a wooded lot), but they also did routine gutter maintenance and repairs where some had gotten a little banged up when branches fell on them, all BEFORE they installed the new filter screens. Water now pours out of the gutters clean and in DROVES, and we haven’t seemed to have any further clogging issues at this time. Updates will be forth-coming in the next few months as we see how this product works long term.
