Choosing a New Opener
01
Belt drive
Quiet and smooth. The best choice when there is a bedroom over or next to the garage.
02
Chain drive
Strong, simple and budget-friendly. Ideal for detached garages and heavy doors.
03
Wall-mount (jackshaft)
Mounts beside the door and frees up the ceiling. Great for high ceilings and storage racks.
California law requires a battery backup on new openers, so the door still works when the power is out.
Repair or Replace?
If your opener is under ten years old, a new gear, logic board, sensor or remote usually brings it back. Older units without rolling-code security or battery backup are often worth replacing, especially when the repair would cost close to a new one.
We give you both prices so you can decide, and we never install an opener on a door that is out of balance; we fix the door first so the new opener lasts.

LiftMaster and Chamberlain most often, plus Genie and Linear. We can match what you have so existing remotes keep working.
Many recent openers have Wi-Fi built in. For older ones we can add a compatible smart hub, or install a new Wi-Fi model.
