My husband and I always wanted nice looking, easily sliding patio doors. Our old ones were none of the above. We discovered The Door and Window Specialist at a Home Show where they gave us a quote on the spot. No hassles. We shopped around, came to the conclusion that they were the best deal for what they offered, so we hired them to install our patio doors. The crew was reliable. They cleaned up afterwards. We are happy with the doors. They are rather attractive- looking.They actually made our rooms look larger. They are definitley a nice upgrade in our home. We get compliments on them all the time. We would recommend The Door and Window Specialist to anyone.
