A snapped garage door spring doesn't give you much warning. One day your door works fine. The next, it's dead weight, and you're staring at a repair bill. In our years serving Dexter, we've seen this problem again and again: homeowners ignore the early signs, then face emergency calls that cost far more than preventive maintenance would have.
The good news? Understanding how springs fail and what they cost to replace puts you in control of your budget instead of letting your garage door control it.
Your garage door springs carry tension that balances the door's weight. Most residential doors use either torsion springs (mounted above the door) or extension springs (along the sides). Both types are under constant stress, opening and closing 1,000 to 1,500 times per year.
Springs typically last 7 to 9 years in normal conditions. That's not a hard expiration date, but it's realistic. Rust, temperature swings, and heavy use can shorten that window. In Dexter's wet climate, moisture accelerates corrosion, so regular inspection is worth the effort.
A snapped spring usually happens without warning. The door either won't open at all, or it rises unevenly and gets stuck. If you hear a loud bang from the garage, that's often a spring giving way. Don't force the door upward manually. A broken spring means the door's full weight falls on the opener and cables, creating a safety hazard and compounding repair costs.
Extension springs fail more frequently than torsion springs. They're exposed to the elements and take more direct stress over time. Torsion springs are heavier-duty but still vulnerable to rust and wear.
If you're not sure which type you have, look above your door. A horizontal metal rod with a spring coiled around it is a torsion spring. Springs running parallel to the door tracks on each side are extension springs. Knowing this helps you understand what a technician will quote and compare estimates fairly.

Spring replacement costs depend on the type and quality. A single extension spring typically runs $150 to $300 installed. Torsion springs, which require specialized tools and expertise, usually cost $200 to $400 per spring. Many doors have two springs, so budget accordingly.
The price gap exists for good reason. Torsion spring installation demands precision and safety equipment. If a technician installs them incorrectly, the door becomes dangerous. It's not a task to hand to a handyman unless they've done it hundreds of times.
Quality matters more than you'd think. Cheap springs fail faster. Better-grade springs cost 20 to 40 percent more upfront but last longer and perform more reliably. Over the 7 to 9 year lifespan, the difference shrinks significantly.
To avoid sticker shock, get an estimate before your spring actually breaks. Dexter Garage Doors offers free assessments, so you know the real cost and can plan ahead. A same-day estimate takes the guesswork out of budgeting.
Replacing one spring costs less than replacing two. Replacing springs before emergency failure costs less than replacing springs plus a bent cable, damaged opener, or cracked door panel.
Simple steps reduce breakdown risk. Keep springs and hinges lubricated every six months with a silicone-based garage door lubricant (not WD-40, which attracts dust). Inspect the springs visually each month for rust, cracks, or visible gaps. If one side looks significantly more corroded than the other, call for service.
Weather also plays a role. Our guide on preparing your garage door for winter covers seasonal stress points, including how temperature swings affect spring tension. Springs contract in cold weather and expand in heat, so winter and spring are common failure periods in Oregon.
Never attempt to adjust, repair, or replace a garage door spring yourself. The tension stored in a spring can cause serious injury. Professionals use tools and techniques you won't have, and they carry insurance if something goes wrong.
If your door opens unevenly, moves slowly, or makes creaking sounds you haven't heard before, that's a signal to schedule service soon. Early intervention prevents emergencies. Schedule a free quote today and lock in a service time that works for you.
How long do garage door springs last? Typical residential springs last 7 to 9 years with normal use (about 1,000 to 1,500 cycles per year). Humidity, rust, and heavy use can shorten this lifespan. Regular lubrication and inspection help maximize durability.
Can I replace just one spring if only one breaks? It's wise to replace both springs at once, even if only one snapped. The unbroken spring is equally worn and likely to fail soon, leaving you with another emergency call and service fee within weeks or months.
What's the difference between torsion and extension springs? Torsion springs wrap around a horizontal rod above the door and are more durable but require specialized installation. Extension springs run along the door tracks and fail more often but cost slightly less to replace.
Is spring replacement covered by insurance? Most homeowner policies don't cover spring replacement as maintenance. However, if a spring fails and damages other components, partial coverage may apply. Contact your insurer directly to confirm your policy details.
How do I know if a spring is about to fail? Look for visible rust, a gap or separation in the coil, or uneven door movement. A creaking sound or the door opening and closing at different speeds on each side are also warning signs to call a technician.
