Led by Jaylen Ross, our team answers the phone live at (361) 314-2738, and you’ll get a written price before any work begins.

Garage Door Spring Replacement
Garage Door Spring Replacement means pulling out the old, exhausted coil that lifts your door and installing a fresh spring rated for your door’s exact weight and cycle count. In San Antonio, where doors open and close 1,500 times a year on average, springs typically last 7 to 9 years before metal fatigue wins. You’ll know it’s time when the door feels heavy, opens unevenly, or the spring shows a visible gap in its coil. Marlow Garage Door Repair San Antonio provides Garage Door Spring Repair in San Antonio, replacing both torsion and extension springs, and we stock the common sizes on our trucks so most jobs finish in one visit. Expect to pay $180 to $340 depending on spring type, door weight, and whether you need a single or double spring setup. You’ll see the exact number in writing before we touch a wrench.
When to Call Us
If your door is sagging on one side or the opener strains to lift it, the spring is likely past its working life. Waiting turns a $200 job into a $500 repair when the extra strain bends tracks or burns out your opener motor.
Call us the moment you notice resistance or noise. We’ll diagnose it over the phone, give you a realistic price range, and dispatch a tech who arrives with the right spring on the truck.
What Replacement Covers
We install springs rated for your door’s cycle count, which matters more than brand. A spring rated for 10,000 cycles might cost more upfront, but it outlasts cheaper alternatives that fail in three years.
Every replacement includes a full safety inspection of cables, rollers, and brackets, plus the written price agreed before we begin. The 365-Day Done Right Promise covers the entire job.
Styles & brands we work with
Garage Door Torsion Spring Replacement
Garage Door Torsion Spring Replacement addresses the horizontal spring mounted above your garage door opening, the one that stores mechanical energy by twisting rather than stretching. These springs do most of the lifting on modern doors and carry serious tension, which is why this job is never a DIY project. When a torsion spring fails in San Antonio homes, you’ll typically hear a sharp crack and the door will refuse to open more than a few inches. Marlow Garage Door Repair San Antonio handles torsion spring replacement for all major brands, including LiftMaster, Chamberlain, and Wayne Dalton doors. The work runs $180 to $340 and includes balancing the door afterward so the opener isn’t fighting uneven weight.
Why Torsion Springs Break
San Antonio heat accelerates metal fatigue. Springs in unconditioned garages on the west side of town bake in summer, cooling and reheating daily, which shortens their life compared to shaded installs in Terrell Hills or Windcrest.
Heavy double-car doors also wear torsion springs faster. A double spring system shares the load, so if one breaks, both typically get replaced at the same time to keep tension balanced.
Why You Need a Pro
Torsion springs hold stored kinetic energy, and the winding and unwinding process requires specialized winding bars and precise tension math. Attempting this with improvised tools causes serious injury every year.
Our background-checked technicians torque each spring to manufacturer spec and test the door through multiple open-close cycles before leaving. You get a written price first, and the price on the invoice matches it.
Broken Garage Door Spring
Broken Garage Door Spring means exactly what it sounds like: the coil that counterbalances your door’s weight has snapped, and the door now weighs its full 150 to 300 pounds with nothing to offset it. That’s why your opener motor groans and the door won’t move. In San Antonio neighborhoods like Kirby and Leon Valley, we see springs fail most often in the early morning, when the cold steel from overnight temperature drops meets the stress of that first open. Marlow Garage Door Repair San Antonio fixes broken springs the same day in most cases, and the repair typically costs $180 to $340. Do not attempt to open the door manually with a broken spring. The risk of the door slamming down is real, and the opener’s cable system is not designed to hold that dead weight alone.
What To Do First
Unplug the opener or use the manual release only if the door is fully down. A door that starts to lift with a broken spring can drop without warning.
Then call us. We’ll ask two questions: what you heard, and how old the door is. That tells us which spring type you need, and we’ll bring both sizes on the truck.
One Spring vs Two
Most modern double-wide doors use two torsion springs. If one snapped, the other has the same mileage and is days or weeks from failure. We recommend replacing both to restore even tension and avoid paying for a second service call.
The 365-Day Done Right Promise covers both springs, so you’re not gambling on the remaining one. Written price comes first, every time.
Garage Door Extension Spring
Garage Door Extension Spring refers to the pair of long springs that stretch along the horizontal tracks on either side of your door, common on older single-car garages throughout San Antonio’s established neighborhoods like Alamo Heights and Scenic Oaks. Unlike torsion systems, extension springs pull the door upward by stretching, and when one breaks, it can send a sharp piece of metal flying across the garage. That’s why safety cables running through the center of these springs are not optional. Marlow Garage Door Repair San Antonio replaces extension springs with safety cable included, typically for $180 to $340 depending on door size and spring length. We also convert older extension systems to torsion when the door supports it, which gives smoother operation and longer life.
Safety Cable Requirements
Extension springs without safety cables are a genuine hazard. When one snaps under load, the spring can become a projectile. Modern building practice requires a cable threaded through the spring on every extension system.
We won’t install an extension spring without routing the safety cable. It adds minutes and costs nothing extra.
Signs of Weak Extension Springs
A door that creeps up unevenly, or one side that sits higher than the other when closed, usually means one extension spring has stretched out while the other holds its length. This imbalance stresses the opener carriage and bends hinges.
We measure each spring’s relaxed length to confirm wear, then replace both sides together so the door rides straight.
Garage Door Spring Installation
Garage Door Spring Installation covers both new-build installs and upgrades where you’re replacing an existing spring system with a higher-quality unit rated for more cycles. In San Antonio’s newer developments around Cibolo and Selma, newer doors come with factory springs, but many homeowners upgrade to high-cycle torsion springs after the first failure, because our Garage Door Spring Repair in Cibolo shows the math makes sense. A standard spring lasts about 10,000 cycles, roughly 7 years of normal use, while a high-cycle spring rated for 20,000 cycles often costs only $40 to $60 more. Marlow Garage Door Repair San Antonio installs springs for every major brand, including Amarr and Raynor doors, and every installation runs $180 to $340 with the written price locked before work starts.
High-Cycle Spring Upgrade
If you plan to stay in your home for more than five years, the upgrade usually pays for itself. Fewer replacement visits, less opener wear, and the door balances correctly for a decade instead of half that.
We’ll quote both options on paper before you choose, so you can see the actual dollar difference instead of guessing.
What Sets a Good Install Apart
Proper installation means the spring is wound to the exact number of quarter-turns specified for your door’s height and weight. One turn too few or too many and the opener wastes energy fighting the balance.
We test with a spring tension gauge and confirm the door holds steady at the halfway point before we call the job done. The 365-Day Done Right Promise backs the whole installation.
Garage Door Spring Adjustment
Garage Door Spring Adjustment is the fix when a door opens halfway and stops, drifts closed on its own, or slams down harder than it should. Those symptoms don’t always mean a broken spring. Sometimes the spring has lost tension, the door has settled, or the original install never matched the door’s actual weight. In San Antonio’s older homes, like those around Terrell Hills, we frequently adjust springs installed years ago with doors that later gained weight from added insulation panels. Marlow Garage Door Repair San Antonio performs spring adjustments as part of a full tune-up, typically $120 to $240, and we’ll show you the before-and-after balance readings so you can see the difference.
Adjustment vs Replacement
If the spring is less than a few years old and the coil is intact, an adjustment usually corrects the problem. We inspect for wear first, and if the metal shows fatigue cracks, we recommend replacement instead of tightening a failing part.
We never adjust a spring that’s nearing failure. The spring gets replaced and the door gets balanced once, not twice.
Why Balance Matters
A door balanced properly should stay wherever you position it. If it drifts up or down, the spring is fighting the opener, which shortens the motor life and causes the opener’s chain or belt to stretch.
Our balance check uses a digital pressure gauge, not guesswork. You’ll see the numbers and know the adjustment was done right.
Brands We Service
Our techs train on eight major brands, including the two you’re most likely to find in San Antonio garages: LiftMaster and Chamberlain for openers, and Amarr and Wayne Dalton for doors. We stock OEM springs and hardware for these brands on our trucks, which means the tech arriving for Garage Door Spring Repair in Universal City or at your door in Lackland AFB already has the parts sized for your specific setup.
We also service Craftsman and Raynor systems regularly. Craftsman doors, common in homes built in the 1990s around Leon Valley, often use proprietary spring cones. Raynor doors, popular in newer builds near Cibolo, spec nylon-coated rollers and specific tension ratings. Whether you have one of these or something else entirely, we can diagnose and fix it same day. If you need a home service call for a different door issue, we handle cable repair and full door repair too.

- Your door banged loudly and won’t open. That sound is the spring snapping, and the door is now dead weight. Don’t hit the opener again. Call us, and we’ll send a tech with the replacement spring on the truck.
- The door opens a few inches and stops. Your opener thinks it’s lifting a balanced door, but a broken or weak spring means it’s lifting the full weight. Continuing to run it burns out the motor, turning a spring fix into an opener replacement.
- You see a gap in the spring’s coil. A visible separation in the coil means the spring has already snapped and is done. If it’s a torsion spring, the two halves sit with a gap. This door needs immediate replacement before any opening attempt.
- The door slams shut when you pull the release cord. A functioning spring counters the door’s weight and lets it close gently. If releasing the door sends it crashing down, the spring tension is gone, and the door is dangerous.
- Your door looks uneven on the tracks. One side higher than the other, or a door that binds when opening, points to a spring losing tension on one side. Have it checked before the track bends or the roller snaps off.

How Much Does Garage Door Spring Repair Cost in San Antonio?
Most spring repairs in San Antonio land between $180 and $340, and the spread comes down to three things: spring type, door weight, and whether you need one spring or two. A single torsion spring on a standard single-car door usually runs $180 to $240. A double torsion spring setup on a heavier double-wide door, which most newer San Antonio homes have, typically costs $280 to $340 because both springs get replaced at once. Extension spring jobs run on the lower end, $180 to $260, but if the door lacks safety cables, adding them adds a small parts cost.
What affects the price: spring cycle rating, door height and weight, and whether the spring is a standard size or an uncommon one that requires a trip to a supply house. We keep most common sizes on our trucks, which keeps labor costs predictable. If your spring replacement comes with a full tune-up or track realignment, that adds to the total, and we’ll show you those as separate line items on the written quote.
How to avoid overpaying: ask whether both springs are being replaced or just one, and ask the spring’s cycle rating. A contractor who quotes you $180 and replaces only one spring on a double-spring door is setting you up for a second failure within months. A high-cycle spring might add $40 to the parts cost but doubles the life. Everything, including the cycle rating of the spring going on your door, is listed in the written quote before we begin.
If you’re not sure whether you need a repair or a full replacement, our Garage Door Spring Repair in San Antonio page covers both scenarios. And if you’re outside the city, we also serve Garage Door Spring Repair in Selma and Garage Door Spring Repair in Cibolo with the same transparent pricing.

Frequently Asked Questions About Garage Door Spring Repair in San Antonio
Spring repair means replacing the torsion or extension coils that counterbalance your garage door’s weight, so the opener only does the lifting instead of hoisting dead weight. In San Antonio, most repairs involve installing a new spring rated for your door’s exact size and weight. The work takes 45 to 90 minutes and ends with a balance test to confirm the door opens and closes smoothly.
Most spring repairs are done in under two hours from the time our tech arrives. Our trucks carry common spring sizes for LiftMaster, Chamberlain, Amarr, Wayne Dalton, and Raynor doors, which means no waiting on a parts run. If you’re in San Antonio proper, you can often book morning and have the door working before lunch.
