Garage Door Repair
in San Diego, Open 24/7

Most calls begin with a symptom, not a part name. Match what you see or hear to the repair it usually points to:

• A loud bang, then the door will not lift or the opener strains: a broken spring. See garage door spring repair.
• The door hangs crooked, a cable is loose, or a roller has left the track: see cable repair and off-track doors.
• Grinding, shaking or a rumble as the door moves: worn rollers. See roller replacement.
• A dented, cracked or split section after a bump from a car: see panel replacement and repair.
• The opener hums, reverses, blinks or ignores the remote: see opener repair and installation.
• An old, damaged or uninsulated door you want to retire: see new garage door installation.
• A door that still works but sounds or feels different: see tune-up and maintenance.
• A door stuck open at night, or a car trapped inside: see emergency garage door repair.

Doorup holds CA Contractor License #1156970 (C-61/D-28). The C-61 class is the Contractors State License Board's limited specialty license, and D-28 is its category for doors, gates and activating devices, which covers garage doors and their openers. California requires a contractor's license number in its advertising, which is why it appears on every page of this site.

You can check any contractor before you hire them. Search the license number or business name on the CSLB website, and confirm that the license is current and active, that the classification fits the work, and that the name matches the company at your door. A company that cannot give you a license number for door and opener work is a reason to keep looking.

Garage doors tend to fail at the worst moment: early on a workday with the car inside, or late at night with the door stuck open. Doorup answers (619) 666-6054 at any hour, every day, so an urgent problem does not have to wait for business hours. A door that still runs safely, such as one that is just noisy, can be booked for a time that suits you.

Doorup is a mobile, service-area business: the work happens at your garage, and there is no walk-in shop. The service area covers 31 communities in five regions of San Diego County: Central San Diego, North County Coastal, North County Inland, East County and South Bay. Each community has its own page with the local housing details that shape garage door work there, listed under service areas.

• If the door is open and you heard a bang, leave it open and keep everyone out from under it. A broken spring can let the door drop.
• Unplug the opener if the door is crooked, off track or straining, so it is not run again by habit.
• Never loosen the bolts at the bottom corners of the door, adjust a spring, or try to rewind a cable. Those parts hold the door's full weight.
• If the power is out and the door is closed with intact springs, the red emergency release lets you lift it by hand.

A door that will not open might have a broken spring, an opener fault, or both, since a failing spring wears out the opener as it goes. That is why a repair visit looks at the whole door: springs, cables, rollers, tracks, sections and the opener. Fixing the part that failed without the part that caused it brings the same call back a few weeks later.

A garage door is a system of springs, cables, rollers, sections and an opener, and most failures are one worn part. Replacing that part, then balancing and testing the door, returns it to service. A new door is the better answer when several sections are damaged, the model can no longer be matched, or the door has never been insulated and the garage has become hard to use. A newer opener matters too: California's SB 969 rule requires a battery backup on any opener installed from July 1, 2019, and bars hanging a new door on an older opener that has none.
