I have used Abel & Son four times since 1995. One roof, one window, one door and one storm door. Only the door had a problem (Air leak on extremely windy days) (discovered problem six months after installation during a winter blizzard). Abel & Son corrected the problem in three days after I reported the problem. They stand behind their work. I intend to replace the cedar shacks on my gable ends. Abel & Sons will be the only vendor that i will ask for a quote.
