Garage Door Springs in Bradbury: Torsion vs. Extension Explained
2026-06-09 7 min read
Your garage door rises and falls hundreds of times each year thanks to two small but mighty components: springs. In Bradbury, most residential doors use either torsion or extension springs, and knowing the difference can save you money and headaches. A snapped spring means your door won't open, your car is trapped, and you're facing an emergency call. Let's cut through the confusion and explain what you actually need to know.
How Garage Door Springs Work
Springs counterbalance your door's weight so the opener can lift it with minimal effort. Without them, your garage door opener would burn out in months, or worse, fail suddenly while the door is open.
Torsion springs sit above the door on a horizontal shaft and twist as they wind and unwind. Extension springs run along the sides of the door and stretch like rubber bands. Most modern homes in Bradbury use torsion springs because they're more durable, safer, and last longer. Extension springs are cheaper upfront but require safety cables to contain them if they snap.
Both types fail eventually. Springs last 7 to 9 years with normal use, sometimes longer if you maintain your door well. When one snaps, the other takes the full load and typically fails within weeks.
Torsion Springs: The Better Choice for Bradbury Homes
Torsion springs are the gold standard. They handle the stress more evenly, last longer, and protect your opener from overwork.
A torsion system uses two springs (one on each side of the shaft) that share the load equally. If one fails, the other keeps supporting the door long enough for you to get help. They're engineered to precise specifications based on your door's weight and size, which is why replacement isn't a DIY job.
The cost varies depending on your door's weight and the spring's quality. Most Bradbury homeowners pay between $200 and $400 per spring plus labor. Cheaper springs ($100 to $150) fail faster. Better-made springs ($300 to $500) last the full 7 to 9 years and often come with longer warranties.
Extension Springs: Budget Option with Trade-offs
Extension springs cost less initially, typically $100 to $200 per spring. They're common on older homes and lighter doors, but they wear out faster and require safety cables to contain them if they snap.
Safety cables run through the center of each spring. Without them, a snapped extension spring can whip across your garage with enough force to cause serious injury. If your door uses extension springs, inspect those cables annually. They fray and weaken over time.
Replacing extension springs is somewhat simpler than torsion work, but it's still best left to professionals. You're working around high-tension components, and mistakes can injure you or damage your door frame.

Signs Your Springs Are Failing
A snapped spring is obvious: your door won't open, or it opens unevenly and sags on one side. But earlier warning signs matter too.
Listen for loud bangs or pops from above the door. That's a spring under extreme stress, nearing failure. If your door feels heavier than usual or creaks and groans during opening, springs are wearing. Some doors open partway then stop, a sign the opener's sensor detected uneven weight distribution.
Never attempt to open a door with a broken spring manually. The door's full weight, often 300 to 500 pounds, will drop on you. Call a professional immediately. Garage Door Bradbury offers same-day emergency service for this exact situation.
What to Expect: Cost and Timeline
A spring replacement typically takes 1 to 2 hours. The technician will remove the old springs, install new ones calibrated to your door's weight, and test the opener to ensure it's not working too hard.
For an estimate in Bradbury, we'll need your door's height, width, and material. Heavier doors (steel, insulated panels) need stronger springs and cost more. You can schedule a free quote online or call us for a quick phone estimate.
Labor runs $150 to $300 depending on complexity. Total cost for a pair of torsion springs with installation usually falls between $500 and $800. Extension spring replacement is cheaper, around $300 to $500 total.
Why Professional Installation Matters
Springs are under tremendous tension. An improperly wound torsion spring or a cable routed wrong can fail catastrophically. Professional technicians use calibrated equipment, follow safety protocols, and warranty their work.
If your door uses an older opener, we'll also check that it's not straining. Read about choosing the right garage door opener to see if an upgrade makes sense alongside spring replacement.
Your garage door system is only as strong as its weakest link. Springs are that link. Ignoring wear signals or delaying replacement puts your family at risk and costs more in the long run.

Frequently Asked Questions
How often do garage door springs need replacement? Springs typically last 7 to 9 years with standard use (opening and closing 4 to 8 times daily). Frequent use shortens lifespan. Proper maintenance and lubrication extend it. Many springs fail suddenly without warning.
Can I replace a garage door spring myself? No. Springs are under extreme tension (up to 400 pounds per spring) and require specialized tools and knowledge. Improper installation or tensioning can cause injury or equipment damage. Always hire a licensed professional.
What's the difference between a snapped spring and a stretched spring? A snapped spring breaks completely, preventing the door from opening. A stretched spring has lost tension gradually, making the door feel heavier and causing uneven opening. Both require replacement, not repair.
Why do both springs fail even though only one snapped? Springs are matched pairs sharing the load equally. When one fails, the other immediately bears double stress. It typically fails within weeks. Replace both springs at once to avoid a second emergency call.
Is spring replacement covered by homeowners insurance? Rarely. Springs are considered normal wear and tear. Some warranties cover manufacturing defects within the first year. Check your door or opener warranty, or ask us about protection plans during your estimate.
