In May 2000 I purchased a Englert LeafGuard gutter system from the LeafGuard Dealer here in Chattanooga, TN. The cost was $1418.00.
The gutters worked as advertised up until the leaves began to come down in the fall. The gutters worked OK on the front of the house where there were no trees. However, the gutters became totally cloged on the back of the house where there are several oak trees. The LeafGuard people came out and unclogged the gutters.
This had to be repeated in the springtime when the oak trees began to shed..the backside of house gutters became completely clogged. This is where the trouble began. I could not get the LeafGuard people to come back out in later years to unclog the back of the house gutters which continued to clog twice a year. The Chattanooga LeafGuard Rep became very argumentative and spoke in a threating manner.
I eventually hired an independent contractor to clean the gutters..they were very difficult to clean as the opening was only about 1/4 inch which prohibited getting the hand in to clean them. I eventually had the gutters removed and replaced with regular open top gutters with a removable cover on top. No problems since. The LeafGuard Gutters do not perform as LeafGuard claims.
They will clog and the LeafGuard people may or may not honor the warranty. The gutters are way overpriced.
