Two years ago I had all the windows replaced in my home for $10,000 by Cambridge. It took 2 days and the installers damaged my walls, window trim and never even cleaned the windows. I had to make a poor review & complaint for them to come back. Once they did they cleaned the windows and used dap to try to fix the trim, which came off a week later. Whatever they used to to seal the windows leaked out about 2 months later and ran down my walls, which has wrecked my paint. If you use inexperienced installers for your company, this is what you get for service. Since I had to call many times to get them to the house the first time with shotty work, I haven't called them a second time as I feel they will be more trouble than it's worth.
