A garage door spring that lets go sounds like a gunshot in the garage, and it almost always happens when you’re already running late. The door won’t lift, the car is trapped, and the whole day stalls. Fernbrook Garage Doors San Antonio has repaired thousands of broken springs across Alamo Heights, Castle Hills, and Terrell Hills since opening our doors in 2002, and we answer the phone live, 24 hours a day. Jesse Calder leads our San Antonio team with a simple promise: a written price before any work starts, shoe covers on every floor we cross, and the spring done right the first time. Call (806) 602-8374 and a real person will pick up, not a voicemail tree.
Garage Door Spring Replacement
Garage Door Spring Replacement means removing the old, fatigued spring or pair of springs and installing new ones matched to your door’s exact weight, height, and track radius. You need it when a spring has snapped, stretched past its usable life, or lost enough tension that the opener strains to lift the door. In San Antonio, most residential spring replacements run between $180 and $340, and Fernbrook Garage Doors San Antonio writes that number down before we touch a single bolt. We carry springs for home doors from Amarr, Wayne Dalton, and Raynor on the truck, so there’s rarely a second trip.
Single and Double Spring Systems
A single-spring door fails completely when the spring breaks. A double-spring door might still open manually, but the remaining spring carries double the load it was designed for. We inspect both springs on every visit and replace them as a matched set when the second one shows visible wear, because a lone new spring on an old partner pulls the door unevenly.
What the Replacement Includes
The price covers the springs, the labor, and a full cycle test where we run the door up and down several times to verify balance. We also lubricate the rollers and hinges lightly, using a pet-safe lubricant, and check the cables for fraying while we’re there. You’ll know the exact total before we begin, and that number doesn’t move.
Styles & brands we work with
Garage Door Torsion Spring Replacement
Garage Door Spring Repair in San Antonio often starts with torsion spring replacement, the most common spring job on local homes with sectional overhead doors. Torsion springs sit on a steel shaft above the door, winding and unwinding under enormous tension to counterbalance the door’s weight. When one breaks, the door becomes dead weight, often 150 to 300 pounds, and no opener on the market is designed to lift it. Fernbrook Garage Doors San Antonio performs torsion spring replacement for $180 to $340, and we bring the correct wire gauge, inside diameter, and spring length for your specific door rather than guessing from a photo.
Why Two Springs Usually Get Replaced Together
Torsion springs are rated for roughly 10,000 cycles, and when one fails, its partner has lived the same life. Replacing only the broken one leaves a worn spring that will likely snap within months. We show you both springs before we quote, so the decision is yours, but the written estimate covers the pair.
The Winding Process
Winding a torsion spring means loading it with tension using calibrated winding bars, and getting the turn count wrong turns the door into a hazard. Our technicians wind to the manufacturer’s specification for your exact door weight, then fine-tune with a balance test at the halfway point. This is not a job we ever recommend as a DIY project, the stored energy in these springs can cause serious injury if released improperly.
Broken Garage Door Spring
A Broken Garage Door Spring means the coiled component that counterbalances your door has snapped, usually with a loud bang, and the door will not open without being forced. The failure often occurs at the weakest point, a fatigue crack that grew over years of daily cycles. Fernbrook Garage Doors San Antonio replaces broken springs across San Antonio for $180 to $340, and in most cases we arrive the same day you call from neighborhoods like Live Oak or Timberwood Park. We open the door manually first, secure it, and then show you the break before we begin.
What You’ll See at the Break Point
Most torsion springs snap into two roughly equal coils with a visible gap, or they show a clean diagonal shear at the end cone. Extension springs stretch out and dangle when they break, sometimes leaving a safety cable hanging loose. Either failure means the door’s full weight now rests on the opener, the cables, or the floor.
Don’t Run the Opener
The safe move after a spring breaks is to leave the opener alone. Pulling the emergency release cord lets you lift the door by hand, but a door with a snapped spring is heavy, and it can slam back down. Call us at (806) 602-8374, and we’ll walk you through securing the door until we arrive. A broken spring is dangerous, but it’s also one of the most routine repairs we handle.
Garage Door Extension Spring
Garage Door Extension Spring systems run perpendicular to the door along the horizontal tracks, stretching and contracting as the door moves. They’re common on older San Antonio homes, less common on new builds, and they fail differently than torsion springs. When an extension spring snaps, it can send a jagged end flying across the garage unless a safety cable is threaded through it. Fernbrook Garage Doors San Antonio replaces extension springs in pairs for $180 to $340, always installing or reusing the safety cable, and we check the pulleys and brackets while we work.
How We Match the Spring to the Door
Extension springs are color-coded by weight rating, but the paint can fade after a decade in a Texas garage. We weigh the door rather than trusting the color, then select a spring that pulls within the manufacturer’s tolerance. A spring that’s too strong makes the door feel like it wants to fly up. One that’s too weak leaves the opener doing the work, and that shortens the opener’s life.
Safety Cables Are Part of Every Job
We won’t install extension springs without safety cables running through them and anchored to the track. It’s a $10 part that prevents a spring from becoming a projectile. If your old system lacks them, we include them in the written estimate and show you exactly where they run.
Garage Door Spring Installation
Garage Door Spring Installation covers both new doors that need springs from the start and existing doors getting fresh springs after years of service. New construction in neighborhoods like Bulverde and Fair Oaks Ranch frequently involves a door with no springs yet, while an older home may simply need the originals replaced. Fernbrook Garage Doors San Antonio handles both, with spring installation priced at $180 to $340 for standard residential doors. We measure the door, calculate the spring constant needed, and install to manufacturer spec.
New Door or Replacement Springs
On a new door, the springs arrive sized from the factory, and our job is to mount, wind, and balance them correctly. On an older door, we account for years of wear on the tracks and rollers that can change how the door moves. The same written-price rule applies either way, you see the number before we start.
Pairing the Spring to the Door’s Cycle Life
Not all springs of the same size are equal. We can install standard 10,000-cycle springs or step up to high-cycle springs that add years of daily use before replacement. The price difference is modest, and we explain the trade-off in plain numbers, so you can decide based on how long you plan to stay in the house.
Garage Door Spring Adjustment
Garage Door Spring Adjustment means adding or releasing tension on an existing spring so the door balances properly. You may need it when your door feels heavy at the bottom, races up too quickly, or drifts closed after opening halfway. In San Antonio’s heat, springs settle and lose a small amount of tension over time, and an adjustment usually takes under an hour. Fernbrook Garage Doors San Antonio performs spring adjustments, and while the price typically falls below a full replacement, we quote it exactly after we see the door.
Signs the Tension Is Off
A balanced door stays put when you let go at the halfway point. If it creeps down, you need more tension. If it climbs on its own, the spring is overwound, and that strains the opener’s gears. We use the halfway test on every single visit because it catches imbalance before it becomes a broken cable or a burned-out motor.
Why Adjusting Isn’t Always Enough
Sometimes the spring has lost tension because it’s fatigued and nearing the end of its cycle life. Adding another quarter turn to a worn spring can buy a few weeks, but it may also accelerate the failure. We’ll tell you honestly if adjustment is a short-term fix or if replacement makes more sense, and the estimate covers either path.
Signs You Need a Pro Right Now
- You heard a loud bang from the garage. That sound is almost always a torsion spring snapping under tension. The door won’t open safely until the spring is replaced, and TECL-experienced technicians are the right call for this repair because of the stored energy involved.
- The door feels unusually heavy or won’t lift more than a foot. The spring is doing less work, which means the opener is doing more. That’s the fastest way to burn out a motor that would otherwise last another decade, and it’s a clear sign the spring is failing or broken.
- You see a gap in the spring above the door. A torsion spring separates into two distinct coils when it breaks, leaving a visible gap where the metal sheared. If you can see it from the floor, don’t stand directly under it, and don’t try to close the door by hand from a ladder.
- The door slams down when you try to close it by hand. A healthy spring controls the descent. A broken or under-tensioned one lets gravity win, and that’s how fingers get pinched and tracks get bent.
- The opener strains, hums, or reverses mid-cycle. Your opener is telling you the door is too heavy. Forcing it to keep working with a dead spring destroys the motor and the gear assembly, turning a $180 spring job into a full opener replacement.

- 1
We answer live and listen. When you call (806) 602-8374, a person answers. You tell us what happened, we ask a few questions about the door, and we schedule the visit. If it’s an emergency, that visit happens the same day.
- 2
We inspect before we estimate. The technician arrives, puts on shoe covers at the garage entry, and uses a digital door scale to weigh the door. That measurement, not a guess, determines the spring size. We also check the cables, rollers, and track alignment while we’re there.
- 3
You get a written price. Before any tool comes out, you see the total on paper. It includes the springs, the labor, the safety cable if applicable, and any small parts like bearing plates. The number does not change once you approve it.
- 4
We replace, adjust, and test. Our technicians install and wind the springs to manufacturer spec, then run the door through a full cycle test. We check balance at the halfway point, verify the opener’s force settings, and listen for any sounds that don’t belong.
- 5
We clean up and show you the photo. Drop cloths come up, the floor gets swept, and we take a photo of the clean work area before we leave. You’ll get that photo, and you’ll have our 365-Day Done Right Promise in writing: if it’s not done right, we make it right.
Brands We Service
Our technicians train on eight major brands, and in San Antonio, the doors we see most often are Amarr, Wayne Dalton, and Raynor. Amarr doors are common in newer subdivisions around Timberwood Park and Bulverde, and we keep OEM spring sizing charts for their current models. Their torsion systems are straightforward, but the cable drums differ by track radius, so we measure rather than assume.
Wayne Dalton doors show up regularly in older homes around Alamo Heights and Terrell Hills, and they sometimes use a TorqueMaster spring system tucked inside the tube rather than an exposed torsion spring on the shaft. Those require specific tools and a different winding method, and we carry both. Raynor doors appear in some mid-century garages and commercial adjacent setups. Whether you have one of those brands or any other make, we can help, and we’ll tell you upfront if a specific brand’s parts need to be ordered rather than pulled from the truck.
How Much Does Garage Door Spring Repair Cost in San Antonio?
A typical spring repair in San Antonio runs $180 to $340, and most jobs land near the middle of that range. A single torsion spring on a standard 16-foot residential door usually costs less than a double-spring system on a heavier wooden door, which is why we quote after weighing your specific door. Our written estimate covers the complete repair: both springs when needed, the winding, the cycle test, and the clean-up. We don’t add trip fees or surcharges for after-hours calls.
What moves the price is spring size and cycle rating, not your zip code. A high-cycle spring rated for 20,000 or 30,000 cycles costs a bit more up front and lasts years longer, which matters if you plan to stay in the house. The best way to avoid overpaying is to ask for a written price before the work starts, which happens at every Fernbrook visit by default. You can also ask what the estimate includes, our number covers labor, springs, and any required safety hardware. A free estimate means you’ll know the total before you approve it, and the price you approve is the price you pay.

Frequently Asked Questions About Garage Door Spring Repair in San Antonio
Garage door spring repair means replacing or re-tensioning the coiled springs that counterbalance your door so it opens and closes safely. In nearby communities like New Braunfels and San Antonio, it most often means replacing a snapped torsion spring above the door or a stretched extension spring along the track. The job includes a written price before work starts and a balance test when we finish.
Most residential spring replacements take between 45 minutes and two hours. That includes weighing the door, removing the old springs, installing and winding the new ones, and running the full cycle test. If we need to order a less common spring size for a specialty door, we’ll tell you the timeline before any work is scheduled.
