What Your Neighbors Are Saying
Mike explained the process and showed me the pricing. It was half what I had been told by another company. My windows arrived before the earliest expected date. I was thrilled at that as the installation was in December, when the temperatures here in Castle Rock were not hot and not too cold for the work. All went perfectly. I love the new windows! I couldn’t have asked for better people to deal with!
I was looking to replace 2 sliding glass doors. Mike did an outstanding job showing how the door was made. He went over the exact cost for every item and was professional and friendly. I had 2 other bids and both were much higher and did not go into detail on how they got at that price. If you are looking for sliding glass doors, I would highly recommend these guys. Solid pricing and very professional.
Our salesman and the installer were professional and detailed. Our replacement sliding door with internal shades exceeds our expectations. The installation was completed in a timely manner and Daniel and his team ensured that the work area was perfectly clean when they were finished.
