Garage Door Spring Repair & Replacement in Union City, CA
A snapped torsion spring leaves the door a dead weight of 150 to 400 pounds that no opener will lift, usually with a car behind it. It is our most common emergency call here and the repair we most firmly advise leaving to a technician — a wound spring holds enough energy to injure badly.
Why Union City homes need spring repair done right
In the subdivisions the arithmetic is clean: about 10,000 cycles for a standard spring, roughly seven years at four uses a day, and failures cluster across matched homes. In the old cores it is messier — after decades of piecemeal repairs the springs frequently do not match the door hanging there, so they have been working outside their range for years. We weigh the door and specify from that rather than replacing like for like.
A garage door spring counterbalances a door that can weigh 150–400 lbs, and it stores enormous energy under tension. When it snaps you'll hear a loud bang and the door becomes a dead weight the opener can't lift. Because winding a spring is genuinely dangerous, this is the repair to leave to a certified technician — we carry a full range of torsion and extension springs and replace them safely, in pairs, the same day.
Signs you need spring repair
- A loud bang from the garage
- A ~2-inch gap in a coil spring above the door
- Door won't lift, or feels impossibly heavy by hand
- Opener strains, hums, then gives up
- Door drops fast or crooked when lowering
What we service in Union City
What to expect on your Union City visit
- 1
Identify the spring system
Torsion (shaft above the door) and extension (along the tracks) springs are sized to your door's exact weight, height and cycle needs — we measure wire size, length and inside diameter to match.
- 2
Replace in pairs
When one spring breaks its twin is near the end of the same cycle life. Replacing both prevents a second failure and repeat call-out, and keeps the door balanced.
- 3
Upgrade option
We offer high-cycle springs rated for roughly double the lifespan — worth it on heavy custom doors or homes that cycle the door many times a day.
- 4
Balance & safety test
We wind to the correct tension, confirm the door holds at mid-travel, re-check the safety cables, and verify smooth, quiet operation.
