Our house was built in 1976, its original windows were single pane, wood framed windows. Poorly fitted storm windows had been added. Additionally, the three front windows on the second floor are built into dormers on our gambrel style roof and the wood on the dormers was in very bad shape. We contracted with Three Sons to replace all our windows and repair the dormers. As promised, a group of six hardworking, very polite young men arrived at our house and by the end of the first day, had replaced all 23 windows. A smaller crew came back the following day to complete the external trim work and reface the dormers. We are so pleased with our entire experience with Three Sons; from the timely, detailed quote, the quality of the windows and the workmanship, the efficiency and friendliness of the workers, to the spotless condition in which they left both the interior and exterior of the house.
