What a Garage Door Opener Installation Involves
A garage door opener installation is one visit, and the typical visit runs about 90 minutes on site. Here is what happens in that time, step by step, with numbers from 732 installs in our own records.
What this service covers
Real work by background-checked local technicians, quoted at a flat rate you approve before anything begins.
The door check
The technician checks springs, rollers and balance first, because a new opener on a worn door fails early.
Mounting and wiring
Rail, motor head, wall control and power are installed and wired.
Sensors, limits and force
Photo-eyes are mounted and aligned, then travel limits and force are set and the auto-reverse is tested.
Remotes and keypad
Remotes and an outside keypad are programmed before the technician leaves.
