"Alamo Garage Doors installed a new insulated garage door for our home. The installation team was punctual, professional, and meticulous about their work."

"Tomas and his coworker were awesome. What at first appeared to be a simple garage door opener installation turned out to be not-so-simple. They arrived right on time, and took me through what they were about to do with the install. They identified a couple of problems with the doors themselves and for a very reasonable price repaired that also. In addition, there was part needed for my installation that did not come with the garage door opener. They found the part closeby, went and picked it up and installed it perfectly. My doors now open quietly and smoothly. Will definitely recommend them again. THANK YOU!"

"My automatic garage door wouldn't open due to an obstruction inside the garage. They responded to my inquiry immediately (which was made late in the day) and came out the next day. The technician was a very polite and informative. Within a half an hour or so, he fixed the problem. I would definitely use them again."

"Great company !! Gary came out & did the initial evaluation & ordered the parts needed. Frank came out & did the install. I found both Gary & Frank to be very professional as well as friendly . They answered all my questions & gave me tips to keep the garage door working properly. I wouldnt hesitate to recommend them to anyone. Well done guys !!"

"Called for repair my Genie's garage door opener that could not close. They came by quick and determined that circuit board was gone bad and need to be replaced by a new opener. A new LiftMaster opener is replaced very quick and clean. All functions on the new system are better except only came with one remote control. I wish I could be told beforehand for anything less convenient (or has to pay extra to get back) comparing with old one. Anyway, they are a very trustful good company: Professional and providing a very quick and skillful service!"

"Fantastic service and value! Next Door Garage removed 2 old and broken garage doors and replaced them with new, beautiful doors, new motors, and a system easily operated remotely via cellphone app. They charged about half of the price we got in our first estimate. They used quality materials and did everything on time. Dan, the installation technician was great! He cleaned everything up, was meticulous in the installation, and took the time to make sure that we downloaded the garage door app, knew how to use it, and that we knew how to check and maintain the motor and door rollers. We couldn't recommend Next Door Garage more highly!"
