The end of last year we had 3 windows and our sliding glass door replaced in our home with new energy efficient windows and door. We are very pleased with this remodel. It has made a big difference in noise reduction as well as heat and cold reduction. The installation was done well, quickly and neatly. We hardly knew that they had been there after it was all over. It was amazing how it all got done so fast. We have had no problems since it was done 5 months ago. We felt the total cost was very fair and my wife and I are very glad we did it. I am a perfectionist and I really like the quality of the products very much. I would definitely recommend the company to anyone and I believe I have already done so. If not, when anyone is looking to replace old windows or a sliding glass door, I will highly recommend they get in touch with the company. One tip I would give any customer is to ask a lot of questions, which I am known for, so there are NO surprises and you are totally satisfied when the job is completed. I appreciated the time given me to answer all my questions. We are now experiencing the joy of making a wise decision concerning having our 3 new windows and sliding glass door replaced in our home.
