Gutters were sagging, which we noticed recently when they failed to drain properly during a heavy rain and we had overflow and some water in our basement. Asked D & B, who installed the gutters, to come take a look and repair. They removed nails holding gutters up in affected areas and replaced them with screws.
I was incredibly pleased. Two very friendly workers showed up late in the afternoon and did a quick inspection. They quoted us $100 to do the repair then and there. They intended to focus on the front of the house where the problem was, but ended up making repairs all around the house. They took the time to make repairs and straighten gutter screens that were out of whack. They also pointed out that if we have any problems with sagging this winter, they would come out.
