We had got two estimates - the second one also from a top-rated provider on Angie's List. We decided to go with Alert Door primarily because we already had a positive experience with this company. Three years back they had repaired our old garage door (replaced broken spring etc.) and the door had been functioning without any issues since. Dan, who had done the repairs then, had also given an estimate for a new door at my request at that time, so I called him recently to ask if I could have an updated estimate. He came over and left a revised estimate which was actually close to the one from 3 years ago. The estimate from the other provider was not only higher, it seemed like the technician/sales person who came by was not too interested in getting my business. Dan and his colleague Chris came by on the scheduled day to do the install (they were a bit late in arriving, but finished the whole job in just 3 hours or so. They also took the time to explain every aspect of the new door system and, looking at the finished work, we were glad we had hired them to do the job - our door looks and operates great! More importantly, we know that if we have any problems, we can always count on them to address it.
