When they installed my windows they partially filled the gap between the window frame and the house with one small bead of foam insulation. This was not enough to completely fill the gap which is the correct way to do the job. They said it would take to long to fill properly and that they needed to get to the next job. They also removed a large picture window and framed in a smaller window. Some of the frame work needed to be covered with three quarter plywood to match the wood on the side of my home which the siding is attached to. Instead they used half inch plywood and built it out with furring strips which left a gap. They covered the gap with metal. When I complained they sent out a quality control person. All he did was make excuses and said their jobs were over booked. Nothing was fixed the right way and the short cuts were left as is. This company doesn't allow enough time to do the jobs correctly so short cuts are taken and installation is done incorrectly. Avoid this company.
