A customer called last Tuesday asking why her garage door wouldn't open. She'd heard a loud bang the night before but thought nothing of it. Turns out, one of her torsion springs had snapped. This is the most common garage door emergency I handle in Windsor, and it's almost always avoidable with basic knowledge. Garage door springs in Windsor typically last 7 to 9 years, not 10. Most homeowners don't realize they're under constant tension until they fail.
Your garage door weighs between 300 and 500 pounds. Two springs counterbalance that weight so your opener doesn't burn out in six months. Torsion springs sit above the door and twist to lift it. Extension springs hang on either side and stretch. Both types carry enormous tension. When one snaps, the other takes the full load and usually follows within weeks.
Springs aren't cheap to replace, but they're cheaper than an emergency call at 11 p.m. or a damaged opener. A single torsion spring replacement runs $200 to $400 including labor. Extension springs cost $150 to $300 per pair. Many folks are shocked by this until I explain that springs are engineered components made to precise specifications, and installation requires specialized tools and safety training.
Before a spring snaps completely, it usually shows signs. Listen for creaking or squeaking when the door opens. Watch for uneven movement or the door sagging on one side. If the door feels heavier than normal or your opener struggles more than usual, that's a red flag. A partially weakened spring means the other spring is working overtime and will fail soon.
Never ignore a snapped spring. Attempting a DIY repair is dangerous and typically voids your warranty. I've seen people try to prop open a door with a spring out, only to have it slam down on a car or person. It's not worth the risk. Our team at Garage Door Windsor can schedule a free quote and often handle same-day service for urgent situations.

The cost of replacement depends on spring type, door size, and whether one or both springs need replacing. A standard residential torsion spring job takes about an hour. If both springs are bad, plan on 1.5 to 2 hours. We always inspect the opener and tracks while we're there because a failed spring often stresses other components.
For homeowners in Windsor and nearby Healdsburg, budget should account for both springs even if only one is visibly broken. Replacing just one leaves the other overworked and destined to fail within weeks. It's a false economy. Some companies will upsell you on unnecessary parts, but I've always recommended replacing both springs at once. It saves you a second service call and keeps your door balanced.
Check our emergency garage door service guide if you're dealing with a stuck or non-responsive door right now. That post covers what to do while waiting for help.
Regular lubrication extends spring life. Use a garage door lubricant spray on the springs and tracks every six months. Don't use WD-40 (it attracts dust) or heavy grease (it collects debris). A light silicone spray works best.
Also inspect your garage door safety features regularly. A malfunctioning safety sensor can mask spring problems or cause the door to reverse unexpectedly. If you haven't had a professional inspection in two years, now's the time. We offer complete maintenance services that catch worn springs before they snap.
Springs are metal under stress. They will eventually fail. The question isn't if, but when. Planning ahead and knowing the warning signs means you won't be stranded with a door that won't open.
If your door is showing signs of spring trouble, don't wait. Call us at 510-902-1438 or get a same-day estimate. We'll tell you exactly what needs replacing and give you an honest price with no surprises.
How do I know if my garage door spring is broken? A snapped spring produces a loud bang. Afterward, the door won't open or feels extremely heavy. You may see the door sitting unevenly in the frame or moving slowly and jerking upward.
Can I replace a garage door spring myself? Springs are under 200+ pounds of tension. DIY replacement risks serious injury or death. Always hire a licensed technician with proper tools and safety training for this job.
How much does a garage door spring cost to replace? A single torsion spring runs $200 to $400 installed. Extension springs cost $150 to $300 per pair. Most doors need both springs replaced together for safety and balance.
How long do garage door springs last? Most residential springs last 7 to 9 years with normal use. Cycles, weather, and maintenance affect lifespan. Springs are rated by cycle count, typically 10,000 to 15,000 cycles.
Should I replace both springs at the same time? Yes. If one spring fails, the other is nearly at the end of its life. Replacing both avoids a second service call within weeks and keeps your door properly balanced.
