Cheapest in San Francisco and Excellent Service Huy is a very experienced guy who works for another well known SF garage door repair company but does this on his own. I called around all of SF and this is by far the cheapest price by $100. He does both Genie and Liftmaster/Chamberlain. He said it would take 1.5 hours and he did. He was fun to talk to, very knowledgeable about the best kind of motor for my old single-piece door, took credit card, and I would totally use him again. If you don't see many reviews it's only because he doesn't ask for them or advertise much.
