Why San Lorenzo homes need opener repair done right

Headroom is the local constraint. A 1944 garage often has too little clearance above the door for a conventional rail-and-trolley opener to sit properly, and where that is the case a wall-mounted jackshaft unit driving the torsion shaft from the side is the right answer rather than a compromise. The other common finding is damp-corroded sensor terminals near the floor of an unheated garage, which cause intermittent reversals that read as a dying board.

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 San Lorenzo 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 San Lorenzo — FAQs

There is no room above my door for an opener. What are the options?

A wall-mounted jackshaft opener drives the torsion shaft from the side and needs no ceiling clearance at all. In garages of this era it is often the only sensible fit, and it is quieter than a chain into the bargain.

My door reverses at random. Opener or sensors?

In an unheated, damp garage it is usually corroded sensor terminals rather than the opener. We clean and re-terminate those connections before recommending a replacement.

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.

“Third house on our street to lose a spring in six months. They came out, replaced both, and then told me plainly which parts on our door had life left and which did not. No upsell, and they were right about the rollers.”
