Called for service one day and GDSR was here the next day by noon to replace garage door opener. Fast, efficient professional service. I received quotes from two other companies. Both quotes were $600 and only included opener, 2 sensors and remotes. GDSR quote included opener, sensors, remotes, a push button and keypad for garage door for less money than others quoted. The installer, Nic was cordial and explained entire system to us. Plus helped us download and app on our cell phones that serve as additional remote. Highly recommend this Father & Son business.
