In our years serving Fairfax, we've seen this problem again and again: homeowners don't know which type of garage door spring they have until one snaps. That's where confusion starts. The two main types are torsion springs and extension springs, and they work differently. Knowing the difference helps you understand what your door needs, why repair costs vary, and when to call a professional. This guide breaks down both types so you can make informed decisions about your garage door.
Torsion springs sit horizontally above your garage door opening. They twist and rotate to lift the door's weight, storing energy as they wind up. Most modern homes in Fairfax use torsion springs because they're durable, smooth, and safer than older designs.
These springs typically last 7 to 9 years under normal use. When a torsion spring fails, you'll hear a loud bang, and your door won't open. The spring has essentially lost its ability to support the door's weight. Replacing a snapped spring requires professional tools and knowledge. We always recommend a licensed technician handle this job because the tension involved is genuinely dangerous. A properly installed torsion spring costs more upfront but lasts longer and operates more quietly than extension springs.
Extension springs run along both sides of your door opening, stretching and contracting as the door moves. They're typically found in older homes or spaces with limited headroom above the door. When working properly, they pull the door up as it opens.
Extension springs are generally cheaper to replace than torsion springs, but they don't last quite as long. Most wear out around 7 to 8 years. They also require safety cables running through them. If an extension spring snaps, the cable prevents it from whipping across your garage, which is a real safety hazard. If you suspect a snapped spring in your Fairfax garage door, don't attempt removal yourself.
Look above your garage door opening. A single horizontal rod with a spring wrapped around it means you have a torsion system. Two springs running vertically along the sides indicate extension springs. Torsion springs are mounted on a metal shaft held by bearings, while extension springs attach to pulleys and cables.
Torsion spring replacement typically costs more than extension spring work because installation requires specialized equipment and expertise. The repair or replacement cost depends on the spring's size, your door's weight, and your location within Fairfax and surrounding areas. Extension springs tend to run 20 to 40 percent less than torsion options. However, both types demand professional installation.

Trying to save money by replacing springs yourself isn't worth the risk. Springs operate under extreme tension. A mistake can cause serious injury or damage to your vehicle. Our team at Garage Door Company Fairfax can provide a free estimate for any spring repair or replacement. We'll assess your current system, discuss the cost difference between types, and explain your best options.
Regular maintenance extends spring life. Lubricate your springs every three months with a silicone-based garage door lubricant. Keep the tracks clean and aligned. Check for rust or corrosion, especially if you live near the coast where salt air accelerates deterioration. For a complete maintenance overview, see what homeowners miss until it's too late.
Springs work harder in cold weather because metal contracts and becomes stiffer. If you notice your door moving slower or struggling to open on chilly mornings, a spring may be weakening. Don't ignore these signs.
If one spring is damaged, you have two choices: replace just the broken one or replace both. We recommend replacing both torsion springs as a pair because they wear at the same rate. Replacing one means the other will likely fail within weeks or months, leaving you with another service call. This approach saves money and hassle in the long run.
For extension springs, the same logic applies. If one snaps, replace both. Your door operates best when springs are evenly matched in age and condition.

How long do garage door springs last? Torsion and extension springs typically last 7 to 9 years with normal use and proper maintenance. Springs are rated for about 10,000 cycles. Frequent opening and closing shortens lifespan.
Can I replace a garage door spring myself? No. Springs operate under extreme tension and require specialized tools. DIY attempts risk serious injury. Always hire a licensed professional to handle spring replacement and installation work.
What's the difference in cost between torsion and extension springs? Torsion springs usually cost 20 to 40 percent more than extension springs, including labor. However, they last slightly longer and operate more smoothly. Your door's design determines which type you need.
Why did my garage door spring snap without warning? Springs wear gradually over years of use. Rust, corrosion, and lack of lubrication accelerate failure. Cold weather also stresses springs. A sudden snap often means the spring was already weakened.
Should I replace both springs if only one broke? Yes. Both springs wear at the same rate, so replacing only one means the other fails soon after. Replacing both together ensures balanced operation and prevents immediate future repairs.
