If you've ever heard a loud bang from your garage. like a firecracker going off. and then found your door wouldn't budge, you've experienced a broken torsion spring firsthand. It's one of the most common service calls we handle here in Schertz, and it almost always happens at the worst possible time: early morning before work, or mid-afternoon when the Texas sun has been hammering your garage for hours.
Schertz's climate plays a real role in this. With humid subtropical summers that push mid-90s temperatures for months on end and humidity that never fully lets up, the metal in your garage door springs faces a relentless cycle of expansion, contraction, and corrosion. Neighborhoods like The Crossvine, Northcliffe, and Belmont Park. most of which feature homes built from the 1990s onward. are filled with doors that are approaching or already past their spring life expectancy. If your home was built around that era, it's worth paying attention.
Your garage door weighs anywhere from 150 to 400 pounds depending on the material and insulation level. Springs are what make that weight manageable. they counterbalance the door so your opener (and your arms) don't have to do all the lifting. Without functioning springs, the opener is essentially trying to drag a car hood off the floor by itself.
There are two types you'll encounter in Schertz homes:
- Torsion springs. mounted on a steel shaft directly above the door opening. These are standard on most homes built after 2000 and are the more durable, safer option. - Extension springs. run along the sides of the tracks and stretch like large rubber bands. More common in older homes and generally less expensive to replace, but they carry more safety risk if they snap.
Most modern Schertz homes use torsion spring systems, which are better suited to handle the weight of insulated steel doors common in newer subdivisions.
Springs don't always fail dramatically. In fact, the early warning signs are easy to miss if you're not paying attention:
- The door feels unusually heavy when lifted manually. Disconnect the opener and try lifting the door by hand to mid-height. a properly balanced door should stay in place. If it drops, your spring tension is off. - The opener strains or reverses without completing the full cycle. When springs weaken, the opener has to compensate, and most modern openers will detect the resistance and reverse as a safety measure. - Jerky, uneven movement. the door shudders or one side rises faster than the other. - A visible gap in the torsion spring coil. look above the door when it's closed. A break in the coil is a dead giveaway. - A sudden loud bang from the garage, usually while the door is in motion or at rest, followed by a door that won't open.
In Schertz's heat and humidity, these signs can escalate quickly. High temperatures reduce metal resilience over time, and without adequate lubrication. which evaporates faster in hot garages. friction between coils accelerates wear. If your springs are already aging, the stress of a South Texas summer can push them past their limit.

Here's a realistic breakdown for homeowners in the San Antonio metro:
- Extension spring replacement: $150,$250 professionally installed - Torsion spring replacement (single): $200,$350 - Torsion spring replacement (pair): $300,$500, all-in with labor and service call
For Texas homeowners broadly, professional torsion spring replacement typically runs $250,$450, covering parts, certified labor, and the service call. Schertz sits in a favorable position here. labor costs tend to be slightly lower than in San Antonio proper, and parts availability is good given the area's growth and proximity to major supply hubs.
One thing worth understanding: always replace springs in pairs, even if only one has broken. The remaining spring is under the same wear and is likely to fail within weeks or months. Replacing both at the same visit saves you another service call fee and keeps your door balanced.
Also ask about high-cycle springs if you're a busy household. Standard springs are rated for roughly 10,000 cycles. about 7 years of average use. High-cycle springs are engineered for 25,000 cycles or more, which is a significantly better long-term investment for families who use the garage as a primary entrance multiple times a day.
We'll be straight with you: garage door spring replacement is genuinely dangerous. Springs operate under extreme tension, and a sudden release can send metal components flying with enough force to cause serious injury or damage your vehicle and door system. Online tutorials rarely account for the exact spring sizing, winding techniques, and safety steps your specific door requires.
For context, the International Door Association reports thousands of garage door-related injuries annually, many tied to improper spring handling. This isn't a "careful person can figure it out" situation. it requires specialized tools and training.
If your door is fully stuck and you need to get your car out before help arrives, use the emergency release cord (usually a red rope hanging from the trolley), but only attempt manual operation if the door is in the closed position and you have someone to help support the weight.
Reach out to schedule a service call and Garage Door Schertz can typically get to most Schertz neighborhoods. including areas near Cibolo and Universal City. same day or next morning.
Most standard torsion springs are rated for about 10,000 cycles. For a household that opens and closes the door four or five times daily, that's roughly 5,7 years. Schertz's heat and humidity can shorten that lifespan by accelerating metal fatigue and corrosion, especially without regular lubrication. High-cycle springs rated for 25,000 cycles are worth the upcharge for busy homes.
No. and it's not just an inconvenience issue. A weakening spring puts excess strain on your opener motor, cables, and drums. Continuing to operate the door can turn a $300 spring replacement into a $600+ repair involving the opener and cables. Stop using the door and call for service.
Generally, no. Standard homeowners policies treat spring failure as normal wear and tear, which is excluded from coverage. However, if a spring breaks and causes damage to another part of your home or property, that resulting damage may be covered depending on your policy. It's worth a quick call to your insurer to clarify your specific coverage.
