Your garage door is heavy, really heavy.
Most garage doors weigh somewhere between 150 and 250 pounds. The spring system is what keeps that weight from being a problem. When a spring breaks or wears out, the door either stops moving entirely or becomes too heavy to operate safely.
For homeowners across San Antonio and the surrounding communities, garage door spring replacement is one of the most common calls we get. This page explains how the system works, what the signs of failure look like, and what the replacement process involves. If your door stopped working and you need help now, call us at (210) 864-9594 or visit our garage door repair page.
Some springs break suddenly with a loud snap. Others wear down gradually and give you warning signs along the way. Here is what to watch for:
Tip If you noticed a loud bang overnight and your door will not open in the morning, a broken torsion spring is the most likely cause. Do not try to force the door open with the opener. Call a technician first. |
Continuing to operate the door after the spring has failed puts the full weight of the door on the opener motor. That can burn out the motor or strip the gears, which turns a spring replacement into a more expensive combined repair.

Most standard springs are rated for around 10,000 cycles. One cycle is one full open and one full close. A household that uses the garage door four times a day reaches that limit in roughly seven years.
A few things shorten that lifespan in San Antonio specifically. The heat cycles here are hard on metal. Springs expand and contract through the summer highs and the occasional winter freeze, and that repeated movement adds up over time. Doors that are used frequently, or that are heavier than average, will wear springs out faster regardless of the cycle rating.
Tip Higher-cycle springs rated for 15,000 to 20,000 cycles cost a bit more upfront and last significantly longer. If your door gets heavy daily use, the upgrade is usually worth it. |
A broken spring is not just an inconvenience. Running the opener with a failed spring puts the full weight of the door on a motor that was designed to assist, not carry. We have seen this burn out openers in Timberwood Park and Leon Valley within minutes of the spring going. The sooner the spring is replaced, the less likely you are to need additional repairs.
Most homes in San Antonio use torsion springs, but older properties in neighborhoods like Hollywood Park and parts of Castle Hills may still have extension springs. The type your door uses affects how the replacement is done and what to expect from the repair.
| Torsion Springs | Extension Springs |
|---|---|
| Mounted on a rod above the door opening | Run along the tracks on each side of the door |
| Twist to store energy when the door closes | Stretch under load to store energy |
| Standard in most modern San Antonio homes | More common in older or low-clearance garages |
| Lifespan: 15,000 to 20,000 cycles | Lifespan: typically around 10,000 cycles |
| Stay on the rod if they break | Can snap and fly loose without a safety cable |
| More balanced, stable operation | More prone to sudden failure |
Not sure which type your home has? Our garage door repair team in San Antonio identifies the spring system during any inspection and recommends the right replacement approach.
A standard single-door spring replacement takes about an hour. Here is what the process looks like from start to finish:
1 | Secure the door and disconnect the opener The door gets clamped before any spring work begins. Nothing moves while we work. The opener is disconnected so it cannot accidentally engage. |
2 | Remove the broken spring safely This step requires specific winding bars and trained technique. A spring under tension cannot be removed without the proper tools. This is the part of the repair that makes DIY genuinely dangerous. |
3 | Measure the door and match the replacement spring We weigh the door and check the dimensions to confirm the right spring specifications. Installing the wrong spring creates an imbalanced door that wears out other components faster. |
4 | Install and wind the new spring The replacement spring is mounted and wound to the exact tension the door requires. Too tight and the door moves too fast. Too loose and the opener has to compensate, which shortens its lifespan. |
5 | Balance test and full system check Once the spring is set, we test the door at multiple points. A properly balanced door holds its position when stopped midway and moves smoothly without straining the opener. We also check cables, rollers, and drums while the hardware is accessible. |
yes. Spring replacements are one of our priority calls. We carry parts for the most common torsion and extension spring sizes, so we can usually handle the repair the same day you call. Availability depends on your location and the time of day, but we will always give you an honest estimate of when we can get there.
Technically the information is out there, but we would not recommend it for most homeowners. Torsion springs operate under several hundred pounds of stored tension. If a spring slips during winding, that energy releases instantly. The repair requires specific winding bars and a precise number of turns based on your door’s exact weight and height. If you want to understand what the process involves before calling, our spring repair page explains the different failure types in more detail.
The cost depends on the spring type, door size, and whether one or both springs need replacing. Torsion springs generally cost more than extension springs, and higher-cycle options cost a bit more upfront but last significantly longer. We give you a clear price before any work starts. No fees added after the job is done.
Most standard springs are rated for around 10,000 cycles. One cycle is one full open and one full close. A household using the garage door four times a day hits that limit in roughly seven years. San Antonio’s heat cycles can shorten that lifespan. Higher-cycle springs rated for 15,000 to 20,000 cycles are available and worth considering if your door sees heavy daily use.
We are available seven days a week, including Sundays and holidays. If your spring breaks at an inconvenient time, call (210) 864-9594 and we will let you know what is available for your area. Do not try to operate the door with the opener while the spring is broken. The full weight of the door goes straight to the motor, and that can cause opener damage that turns a simple repair into a more expensive one.
Yes. We serve homeowners across the northwest San Antonio area, including Timberwood Park, Stone Oak, Shavano Park, Castle Hills, Hollywood Park, and Leon Valley. If you are further out, call us and we will confirm whether we can reach you.
Yes. We work with both types across all standard residential door sizes. If you are not sure which system your home has, we identify it during the inspection. Older homes in neighborhoods like Hollywood Park and parts of Castle Hills often still have extension springs. If your garage has enough headroom, we can also convert from extension to torsion during the same visit, which gives you a longer-lasting and safer setup.
