Alert Door Services Inc 925 North Amphlett Boulevard, San Mateo, CA 94401

"I love Alert Door - they are responsive, knowledgeable, practical and reasonable. In my first house 20 years ago, they kept our 60 year old door working until they helped me realize we could regain a lot of space e if we went with carriage doors. So they helped us design the new doors and install them - they worked flawlessly and were beautiful, all for a reasonable price. When the springs finally went, they were there within 24 hours getting us up and running. Figured out we were using our garage door as our front door so we replaced the springs with more powerful ones and never had to replace them again. In our most recent house we had an old opener and they helped me get a reasonable new one that works well with Amazon deliveries. Had an alignment issue after and they were back at the house in 4 hours. They do great work and they stand behind it. I wish everyone who services our house were as nice, as responsive and as helpful as Alert Door. They have my highest recommendation."

"Excellent service from start to finish. Technician Joe was professional and changed the spring that was broken. I recommend this company and should the need arise would call them again."

"Wonderful, efficient, quality, and friendly service from a family-run business which has been on the peninsula for many years. Dan helped repair a sectional door track which had become misaligned and loose. He also provided care tips for me and is the most pleasant service-man you will ever meet."

"amazing job. i called in the morning and after telling him the issue, he gave me an estimate of the work and time and was even able to come in 10 mins. danny came and put the two cables back and readjusted the spring tension. he even nailed back the side panel without me asking and also oiled up the wheels. he also swapped out the garage door seal since i mentioned that there was a small gap on one side and made sure there is no more gap by adjusting the door. overall, he did an amazing job and i would highly recommend them to anyone looking for a garage door repair."

"Alert Door Services is one of the best companies I have ever worked with. They recently installed new custom made garage doors on a duplex I own. Very professional, nice people to do business with and product is outstanding and a very good value. I highly recommend this company."
