I wish to congratulate Mathieu Dery for the excellent job he did installing my new garage door opener. He called 30 minutes prior, was there on time and installed in less time than expected. He adjusted my door to ensure smooth operation. Workmanship was excellent. He noticed that bracket holding opener was loose on one side and he took the trouble to find strong support and screwed bolt into solid wood. I like a man who pays attention to the little things. Thank you Door Doctor I will definitely use your services again and reference you to my friends.
