"Alamo Garage Doors went above and beyond when replacing my outdated garage door. They helped me choose a design that matched my house and handled the installation perfectly. The new door runs quietly and looks fantastic. The crew was professional, respectful, and left the area spotless. Excellent all-around service."

"We were very pleased with Duplouy! They were efficient, professional, and answered all our questions regarding the new door. We heard from them very quickly after posting the job and they came with samples and a quote on the job within a week. The door took a bit longer to come in ,then we expected, but once it arrived they installed it immediately during one afternoon. I would recommend them to anyone looking to replace a garage door!"

"Showed up on time, we had to wait for the doors (supply chain issue - not the installer). Professional, did all work neatly and efficiently. Highly recommend!!"

From sales to installation, the process was exceptionally smoothly and everything happened as was originally scheduled and promised. Communication was excellent, advice from the estimator was spot-on, the quality of the doors even better than what we expected and the installation was EXPERT. The doors look fabulous, work perfectly, and the installer did a much better job than what we could have done ourselves. We are so glad that we decided to outsource this service and we highly recommend this company.

"Great experience - installers Alex and John came out the same day I had contacted DSI for a quote - my existing door was installed pretty poorly by the previous owner and had huge gaps around the edges, but they leveled it out, fixed the door, installed the operator and all the accessories in a short amount of time and left no mess behind. All in all, a perfect experience and I would recommend DSI to anyone."

"it was a good installation they had a part missing so it took a couple of extra days I did find some nuts and bolts left on the floor from the old doors over all well done"

"Overall a good company. Had a few issues and I am still waiting to hear back on some of the issues that need to be resolved. When I put request in through home advisor and scheduled my first appointment I had to take time off work to be home for appointment window. The guy never showed. I called and he did call me back the next day and offered to come out a day later. He said he would offer a discount for the trouble. We originally called for a repair but after consulting with Patrick the rep, we ended up deciding to replace the both our garage doors. When the tech came to replace the garage doors he did a very good job although did not fix some of the wiring issues that I was having originally when I called. I have a call into the company and spoke with the office staff who said they would get back to me but have not heard from them yet. That was just a few days ago. I will update this review if they do resolve my issue."
