FAQ
Frequently asked questions
Why has my garage door opener stopped working?
The most common causes are a misaligned or blocked photo-eye safety sensor, a failed capacitor or logic board, stripped drive gears, or travel limits that have drifted out of adjustment. A blinking motor-unit light usually points at the safety sensors.
Is it worth repairing an opener or should I replace it?
If the unit is under roughly ten years old and the fault is a single component, repair is usually the better value. Our published guide puts opener repair around $200 to $350. Older units without rolling-code security or a battery backup are often worth replacing outright.
Which opener brands do you install?
We are an authorized LiftMaster dealer and fit the full range: chain drive, belt drive, wall-mount jackshaft, and models with battery backup, built-in camera and LED lighting.
Do new openers work with a phone?
Yes. We set up myQ on install, so you can open, close and monitor the door from your phone and get alerts if it is left open. Security+ 2.0 rolling code is standard.
Do I need a battery backup opener in Florida?
It is worth having. A battery backup keeps the door working through a power cut, which matters in storm season when a garage may be the only way in or out.
