A broken garage door spring is one of the most common — and most urgent — garage door failures. When a spring snaps, the door becomes far too heavy to lift safely and your car can be trapped inside. One Stop Garage Doors & Gates provides fast, licensed garage door spring replacement in Foster City for homes and businesses, including Marlin Cove, Sea Colony, Isle Cove, Harbor Side, and Bay Vista. As a local Santa Clara County company at 1850 Warburton Ave #203 in Santa Clara, we reach Foster City fast, and same-day spring appointments are usually available. Call 650-910-6090.
Signs Your Foster City Garage Door Spring Has Failed
- You Heard a Loud Bang from the Garage – A snapped torsion spring releases its tension all at once and makes a loud bang, often mistaken for something falling. If the door won’t open afterward, a broken spring is the most likely cause.
- The Door Won’t Open or Feels Extremely Heavy – Springs counterbalance the door’s weight. With a broken spring the opener can’t lift the door, or a manual door feels like dead weight and slams back down.
- There’s a Visible Gap in the Torsion Spring – Look at the spring on the bar above the door. A two-to-three-inch gap in the coil is a clear sign the spring has broken and needs replacement.
- The Door Opens Crooked or Jerky – One weak or broken spring on a two-spring door makes the door rise unevenly, bind in the tracks, or move in jerks — a sign the springs are worn and due for replacement.
- The Opener Runs but the Door Barely Moves – If the motor hums and the top of the door lifts an inch then stops, the opener is straining against a failed spring — keep trying and you can burn out the opener too.
- The Cables Have Come Loose or Off the Drum – When a spring fails suddenly the cables often go slack and jump off the drums. Cables and springs are replaced and re-set together for a safe, balanced door.
Torsion & Extension Spring Replacement
We replace both torsion springs (on the bar above the door) and extension springs (along the tracks) on all door sizes and brands in Foster City. Springs are always replaced in matched pairs, cables and drums are checked, and the door is re-balanced and safety-tested before we leave.
24/7 Emergency Spring Replacement
Spring failure doesn’t wait for business hours. If your car is trapped inside or the door won’t close and your home is exposed, we’re on call around the clock. Our Foster City emergency spring replacement covers every neighborhood — fast response, day or night.
Garage Door Spring Services in Foster City
One Stop Garage Doors & Gates provides complete garage door spring replacement in Foster City and across Santa Clara County. Broken torsion spring, snapped extension spring, or a door that suddenly feels impossibly heavy — we replace the spring safely, check the cables and drums, and re-balance the garage door so it opens smoothly again.
Torsion Spring Replacement
Torsion springs mount on the steel shaft above your Foster City garage door and carry the whole weight of the door. When one snaps you hear a loud bang and the door won’t lift. We replace single and double torsion springs in matched pairs and re-balance the door.
Extension Spring Replacement
Extension springs run along the horizontal tracks on lighter Foster City doors. We replace worn or broken extension springs, add or check the safety cables that keep a broken spring from flying loose, and test the full lift.
Broken Spring Emergency Repair
A broken garage door spring can trap your car inside and leave your home exposed. Our Foster City technicians carry common torsion and extension springs on the truck, so most broken-spring calls are fixed same day, 24/7.
Cable & Drum Service
Springs, cables, and drums work as one system. When we replace a spring in Foster City we inspect the lift cables and drums, re-seat or replace frayed cables, and make sure everything winds evenly so the new spring lasts.
Spring Tension & Balance Tune-Up
An unbalanced door burns out springs and openers early. We set the correct spring tension, balance the Foster City door so it holds halfway open, and lubricate the moving parts for quiet, safe operation.
Opener & Safety Check
A door that fought a weak spring can leave the opener strained. After every Foster City spring replacement we test the opener force, reverse safety, and photo-eye sensors so the whole system is safe before we leave.
Garage door springs are under extreme tension and are dangerous to replace without the right tools and training. Our licensed Foster City technicians replace springs the safe way, use correctly-rated springs for your door weight, and back the work with upfront pricing and a workmanship warranty — no surprise fees.

Frequently Asked Questions
Most single torsion spring replacements in Foster City run about $180 to $290, and a matched pair costs more. Extension springs are usually less. We give you an upfront price before any work begins — no surprise fees. Call 650-910-6090.
Yes. A broken spring is urgent, so we prioritize spring calls and same-day service is usually available across Foster City and Santa Clara County, including nights and weekends.
On a two-spring door we recommend replacing both. Springs wear at the same rate, so if one has broken the other is close behind. Replacing the pair saves a second service call and keeps the door balanced.
No. Garage door springs are under extreme tension and cause serious injuries every year. The tools, torsion bars, and technique needed to do it safely are why this is a job for a licensed technician.
