Garage door jammed and I called Monday morning. They told me they couldn't come out until Tuesday, which was fine since I had appointments Monday. But Monday afternoon, the technician called and said he finished his calls early and could come right out if it was okay. He was there in 15 minutes and got the door working properly quickly and efficiently--a whole day early.
He was extremely professional and courteous and took the time to show me how to lubricate the rollers and springs to avoid future problems. No charge, since the door was still under warranty.
These are the kind of people you like doing business with. Would recommend them anytime.
