Broken Spring Repair
A broken garage door spring is one of the most common — and most dangerous — garage door failures. Do not attempt to fix it yourself. Our trained technicians replace torsion and extension springs safely, often the same day you call.
Common Broken Spring Repair Issues We Fix
- Loud bang from the garage followed by the door not opening
- Door feels extremely heavy or won't lift more than a few inches
- Visible gap or separation in the torsion spring above the door
- Extension spring on the side is snapped or hanging loose
- Door opens unevenly or crooked because one spring has failed
- Opener strains or stalls trying to lift the door
What's Included
If you heard a loud bang from your garage and now your door won't open, there's a good chance a spring just broke. Garage door springs are under enormous tension — they're what counterbalances the weight of the door so your opener can lift it. When one breaks, the door becomes dangerously heavy and your opener can't handle the load on its own. This is not a DIY repair. Every year, homeowners are seriously injured attempting to replace garage door springs without proper tools and training.
At Flatirons Garage Doors, spring replacement is one of our most common service calls. We work with both torsion springs (mounted on a shaft above the door) and extension springs (mounted along the horizontal tracks on each side). We use high-cycle springs that are rated to outlast the standard springs that come on most residential doors, so you get more years of trouble-free operation. When your door has two springs and one breaks, we strongly recommend replacing both at the same time — the second spring has the same wear and is likely close behind.
We respond quickly to broken spring calls because we know your vehicle may be trapped in the garage and your daily routine is on hold. Our technicians carry the most common spring sizes on the truck, which means we can usually complete the replacement the same day you call. Reach us at (720) 810-1615 for fast, safe spring repair anywhere on the Colorado Front Range.

Our Process
Call Us Immediately
A broken spring is urgent. Call (720) 810-1615 and we'll prioritize your service call. Do not try to open or close the door — it's under extreme tension and can cause serious injury.
Safe Assessment
Our technician secures the door, identifies the spring type (torsion or extension), and measures your door to select the correct replacement spring for the weight and size.
Spring Replacement
We remove the broken spring, install the new one, and carefully wind it to the correct tension. If both springs are aging, we'll recommend replacing the pair to avoid another failure soon.
Balance and Test
We balance the door, test it manually and with the opener, and verify the safety reverse is functioning properly before wrapping up.
Broken Spring Repair FAQ
Can I open my garage door with a broken spring?
We strongly advise against it. Without the spring counterbalancing the door's weight, the door is extremely heavy and can come crashing down. Your opener is also not designed to lift the full weight alone and can burn out. Keep the door closed and call us.
Why did my garage door spring break?
Garage door springs have a finite lifespan measured in cycles — one cycle is one open and one close. Standard springs last around 10,000 cycles, which is roughly 7 to 10 years of normal use. Temperature swings here in Colorado also put extra stress on the metal, which can shorten spring life.
How long does it take to replace a garage door spring?
A trained technician can typically replace one or both springs in about 45 minutes to an hour. If there are additional issues with cables, drums, or bearings, it may take a bit longer. Most spring replacements are completed in a single visit.
Should I replace both springs even if only one is broken?
Yes, we recommend it. Both springs were installed at the same time and have the same wear. If one has broken, the other is likely very close to failing too. Replacing both now saves you from a second service call and a second day of disruption.
What's the difference between torsion springs and extension springs?
Torsion springs are mounted on a metal shaft directly above the door opening. They twist to store energy and are the more common type on modern doors. Extension springs run along the horizontal tracks on each side of the door and stretch to store energy. Both do the same job, but torsion springs are generally considered safer and more durable.
