A broken garage door spring is one of the most common, and most urgent, garage door failures in Chicago, especially during our brutal winters. When a spring goes, your door usually won't open at all, or it slams shut and traps your car inside.
The good news: spring replacement is a routine, same-day repair when it's done by a pro. Here's exactly what affects the price so you know what a fair quote looks like before you call.
What determines the cost of spring replacement
No honest contractor can quote an exact price sight unseen, because several real factors change the number. The biggest ones are the type of spring, the size and weight of your door, and whether one or both springs need replacing.
- Spring type: torsion springs (mounted above the door) cost more than extension springs (along the tracks) but last longer and operate more smoothly.
- Door size and weight: heavier insulated steel and solid wood doors need higher-cycle, heavier-gauge springs.
- Single vs. double spring system: most pros recommend replacing both springs at once, because if one has failed the other is usually close behind.
- Spring cycle rating: standard springs are rated around 10,000 cycles; high-cycle springs cost more upfront but last far longer.
- Access and condition: rusted hardware, an off-balance door, or a detached garage in tight Chicago alleys can add labor.
Torsion vs. extension springs
Torsion springs sit on a metal shaft above the door opening and use torque to lift the door. They're more durable, safer, and quieter, which is why most modern doors use them.
Extension springs run parallel to the horizontal tracks on each side and stretch as the door closes. They're common on older Chicago garages and tend to wear out faster. Whichever you have, replacing springs is genuinely dangerous DIY work: they store enormous tension and can cause serious injury. This is a job for a trained technician.
Why replacing both springs is usually the smart move
If your door uses two springs and one breaks, the second one has gone through the exact same number of cycles and is likely to fail within weeks. Replacing both during a single visit saves you a second service call and keeps the door balanced, which protects your opener from premature wear.
How to avoid overpaying
- Always get upfront, itemized pricing before any work starts: we never begin a repair without your approval.
- Be wary of suspiciously low "starting at" prices that balloon once the technician arrives.
- Ask about the spring's cycle rating; a slightly higher-cycle spring can double the lifespan for a small premium.
- Bundle in a quick tune-up: lubrication and a balance check while the tech is already there extends the life of the new springs.
