I had to put in a service request after our last rainstorm. Couple of our gutters were overflowing. Leaffilter sent a service tech out without any hassle. We're very pleased with the work our service tech (Keil) did on our gutters. He adjusted a couple of our gutters to drain better towards the down spouts. Thoroughly cleaned the gutters. Caulked the gutters and re-installed the Leaffilter system. Cleaned up afterwards. Keil was very friendly and very knowledgeable. -Kendall M.
