We help you choose the drive that fits your garage, your door weight and how close the living space is.
Old opener removed

Safety sensors, remotes and wall control
Photo-eyes mounted and aligned, remotes and keypads programmed, travel limits and force set.
Situations we fix every week
- Need a quiet garage door opener for a room above the garage?A belt-drive opener is the usual answer, because a rubber-reinforced belt runs much quieter than a metal chain. A wall-mount opener helps too, since the motor is off the ceiling. A noisy door can still be loud with a good opener, so check that too.How we fix it
- Getting a new garage door: do you replace the opener too?Keep the opener if it is modern, has working safety sensors, and is strong enough for the new door. Replace it if it is old, loud, or the new door is heavier or taller. Installing both together is common, and the opener is set for the new door in the same visit.How we fix it
- Does your tall or 8-foot garage door need a different opener?A standard garage door opener comes with a rail for a 7-foot door. A taller door, an 8-foot door or a high-lift track needs a longer rail, or a rail extension, so the garage door opener can lift the door all the way.How we fix it
- Got stuck in the garage in a power outage? Get a battery backup opener.A garage door opener with battery backup keeps the garage door opener running when the power is out, so you can open and close the door normally. Many current openers offer it, and it can go in with a new opener.How we fix it
- Belt drive or chain drive opener?Choose belt if the garage shares a wall or ceiling with living space. Choose chain if you want a tough, simple drive and noise is not a worry. Either works well when it matches the door and is installed properly.How we fix it
