There's a reason garage door spring replacement is one of the most searched repair topics for homeowners in the San Antonio metro area. it's also one of the most common reasons a door completely stops working. Out here in Adkins, where summer heat and year-round humidity put extra stress on metal components, springs tend to wear out faster than the national average. If your door suddenly won't open, or you heard a loud bang from the garage overnight, there's a good chance a spring just let go.
Here's a plain-English breakdown of how garage door springs work, what failure looks like, what it costs to fix, and why this particular repair is one you really should leave to a professional.
Your garage door can weigh anywhere from 150 to 400 pounds depending on its size and material. The spring system is what makes it possible for a relatively small opener motor. or even your own arm. to lift that weight without straining. Springs store mechanical energy when the door closes and release it to assist the lift when the door opens.
There are two main types:
Torsion springs are mounted horizontally on a steel shaft directly above the garage door opening. They work by twisting along the shaft, storing torque that helps lift the door evenly from both sides. Torsion springs are more durable, provide smoother and quieter operation, and typically last 10,000,20,000 cycles depending on the quality you choose. Most newer homes in Adkins and nearby Schertz are built with torsion spring systems as standard.
Extension springs run along the horizontal tracks on either side of the door. They stretch and contract with every cycle. They're less expensive upfront, but they wear out faster and carry a higher safety risk when they break. a snapped extension spring can go flying if safety cables aren't installed alongside them. Older homes and lighter doors are more likely to use this system.
Don't wait for a complete failure before taking action. These are the warning signs that a spring is near the end of its life:
- The door feels unusually heavy when you disconnect the opener and try to lift it manually. A properly balanced door should stay open at about waist height on its own. - The door doesn't stay open or drifts back down after you let go. this points to lost spring tension. - Visible gaps in the spring coil. A torsion spring that has snapped will have a visible separation in the coil. You can see this just by looking above the door opening. - Grinding or squeaking when the door operates, especially if you've already lubricated the rollers and hinges. This can indicate a spring under uneven tension. - The door opens crookedly. tilting to one side. which often means one spring has failed while the other is still intact.
If your door is making any of these signs, stop using it and reach out to schedule an inspection. Running an opener motor against a broken spring will burn it out quickly.
In Texas, professional garage door spring replacement typically runs $250 to $450 for most standard residential jobs, covering parts, labor, and the service call. The final number depends on the type of spring (torsion costs more than extension), the size and weight of your door, and whether both springs need to be replaced.
On that last point: if one spring has broken, the other one is almost certainly close behind. Both springs are the same age and have seen the same wear cycles. Replacing both at the same time saves you a second service call fee in a few months. most technicians will recommend this and it's the right call. You can explore the full range of repair and replacement services available to understand what a complete job includes.
For a heavy double-car door or a door with high-cycle springs designed for long-term performance, costs can run higher. Emergency service calls outside normal business hours typically add $50,$100 to the bill.
Adkins sits in a humid subtropical climate where summers regularly push past 95°F with a heat index that can feel like 115°F or more. That kind of environment accelerates spring wear in two specific ways. First, repeated thermal expansion and contraction from daily temperature swings. sometimes 30,40 degrees between a summer morning and afternoon. stresses the metal over time. Second, humidity promotes rust and corrosion on the spring coils themselves, weakening the metal from the outside in. Homeowners in Adkins and neighboring Floresville should expect to replace springs somewhat sooner than the theoretical lifespan suggests, particularly if the springs haven't been kept lubricated.

This isn't the usual disclaimer boilerplate. it's a genuine safety concern. Garage door springs are under enormous tension. A torsion spring stores enough energy to cause serious injury or death if it releases suddenly during installation. A spring release can send metal components flying across a garage at high speed. The tools required to wind and tension a torsion spring correctly. winding bars, a torque-calibrated system. are not standard homeowner equipment, and online tutorials rarely account for the exact spring specs your door actually needs.
Professional technicians match spring size precisely to your door's weight and usage, ensure cables and drums are in good condition, and perform a full balance check before leaving. That's what you're paying for. not just the part.
Q: How long do garage door springs last in the Adkins area? A: Standard springs are rated for about 10,000 cycles. If you use your door four times a day, that's roughly seven years. but South Texas heat and humidity can reduce that lifespan. High-cycle springs rated for 25,000+ cycles are worth the extra upfront cost if you use your garage frequently.
Q: Can I still use my garage door if a spring is broken? A: You should not. Operating the opener against a broken spring puts extreme strain on the opener motor and cables, which can cause additional costly damage. You can manually lift the door in an emergency, but it will be very heavy. Disconnect the opener and contact a technician before using the door again.
Q: Do both springs always need to be replaced at the same time? A: In most cases, yes. Both springs age together, so when one breaks, the other is typically close behind. Replacing both in a single visit saves you a second service call fee and keeps your door operating with balanced tension on both sides.
