Why Cotati homes need opener repair done right

On rentals the commonest call is not a fault at all: lost or unpaired remotes, and keypads nobody has the code for between tenancies. Modern Wi-Fi openers solve that properly, because access can be granted and revoked without hunting for handsets. The genuine faults here follow the housing — stripped drive gears on ageing units in the newer subdivisions, and damp-related sensor terminal corrosion on the older detached garages.

The opener is the motor and brain of the door — and California law (SB-969) now requires battery backup on newly installed openers. We diagnose and repair every major brand, from a slipped drive gear or bad logic board to misaligned safety sensors, and install modern Wi-Fi openers with myQ smartphone control and battery backup that keeps you covered during a power outage.

What to expect on your Cotati visit

1
Diagnose motor vs. door
Half of 'opener' problems are actually a spring, cable or sensor issue overworking the motor. We confirm the real cause before recommending a repair or replacement.
2
Repair or right-size a new unit
We repair boards, gears and sensors where it makes sense, or recommend the correct horsepower drive (chain, belt, or quiet wall-mount) for your door's weight.
3
Smart + battery-backup setup
New installs include Wi-Fi (myQ) pairing and a code-compliant battery backup, so the door still opens when the power is out.
4
Safety calibration
We set travel limits and closing force, align the photo-eyes, and test auto-reverse against an obstruction so the door meets safety standards.

Opener Repair in Cotati — FAQs

Can you sort out access between tenants?

Yes. A modern Wi-Fi opener lets an owner or manager grant and revoke access without chasing handsets, and we can clear existing paired remotes so an old one no longer opens the door.

Does a new opener need battery backup?

Yes — California requires it on newly installed residential openers, so a power cut cannot trap a car inside.

Is my opener worth repairing or should I replace it?

If the unit is under ~10 years old and the fault is a gear, board, or sensor, repair is usually the better value. Older openers without rolling-code security or battery backup are often worth replacing for safety and smart features.

Do new garage door openers need battery backup in California?

Yes. California SB-969 requires battery backup on residential garage door openers installed since mid-2019, so the door can be opened during a power outage. Every opener we install meets that requirement.

Can you make my existing opener work with my phone?

Often, yes — many openers accept a myQ or smart module retrofit. If yours doesn't, a modern Wi-Fi opener adds smartphone control, alerts, and remote open/close.

Why does my door reverse before it closes?

Usually a misaligned or dirty photo-eye sensor, or a closing-force setting that's too sensitive. Both are quick calibrations — but a binding door can cause it too, which is why we check the whole system.

“Our garage sits at a strange angle off the plaza and two firms had told us a new door would not fit. They measured it, said exactly what would work and why, and fitted it without any drama. First people who treated the odd shape as normal.”
