We looked into windows a year ago, but put it off until end of Feb when a sale convinced us to do 2 windows where condensation was causing issues. They arrived when expected, cleared snow off the roof to access the windows, layed down mats and got to work. The work took much longer than anticipated (areas surrounding the frame were rotten and needed replacing), they took care of it and cleaned up after themselves and replaced the window fixtures. The windows made a huge improvement, and the initial advice on picking the type/style was appreciated and turned out well. It was well worth the investment and we are very pleased.
