Your company replaced the old windows in my home. They were replaced with six regular double hung, three 2 lite sliders and one casement picture window. They both look wonderful and work great. Since we have had the windows replaced, the heat in our home has been nice and even, no cold spots. The help that we received from Dave was very much appreciated and very helpful. We have had a wonderful experience with your company and would recommend our friends and relatives to you also.
