A garage door spring works harder than any other part of the system, cycling every time the door moves to carry the full weight of the panels. When that spring fails, the door stops cold and so does everything that depends on it.
At Select Garage Doors, we provide fast garage door spring repair for homes across Thornton, CO. Our technicians replace torsion and extension springs on sectional and rolling steel doors, rebalance the system, and test it fully so your door is back in safe working order with as little disruption as possible.

Don't Take Our Word For It — Hear From 1,900+ Five-Star Reviews
Had a garage door put in in February it broke down in August. But they came and fixed it up all nice now it works great and they didn’t charge me for the repair service. So I think they did great on the fixer upper. And I would recommend them for garage door services they were nice and super professional about the whole thing. They let me know they stand by there products which is always a good motto to have and fixed me up nicely

I scheduled an appointment for an estimate. They were able to install right then. It didn’t take long and they cleaned everything up after themselves. The install went very well and they were meticulous about where the wires were placed coming out of the ceiling and kept it organized. The door opener is very quiet which is really nice.

I am so glad I called Select Garage doors. My spring broke on my garage door and locked me out of access to my house. They responded same day and were fast and efficient making sure we were aware of all things needed to keep the garage working. Technician was super informative and friendly as well. 100% recommend.

I called on a Saturday because my garage opener stopped working. Shaun came out the same day. Provided an estimate and he was back Sunday morning to replace it. Highly recommend!
Eric Peck
I had a very noisy garage door repair issue that was waking up my kids every morning. The technician replaced the rollers and checked the Genie opener repair needs. It’s now whisper-quiet! I am so happy with the price and the same-day garage door service.
Elliott Denisse
I’m absolutely thrilled with the service I received from Select Garage Doors! They installed a new garage door opener for me and were fantastic. On time, efficient, and explained everything thoroughly. Great price too, highly recommend!

Why a Broken Spring Is a Bigger Problem Than It Looks for Thornton Homeowners
A garage door spring carries the entire load on every cycle. When it weakens or snaps, the opener is forced to drag a door it was never designed to lift on its own, which quickly strains the motor, cables, and tracks and can take the whole system out of service.
For a Thornton homeowner, that failure goes beyond a repair bill. A door stuck open leaves your vehicles, tools, and belongings exposed. A door stuck closed means no way in or out until the problem is fixed. Getting a professional on-site quickly restores safe operation and protects the surrounding hardware from a far more expensive round of damage.
Thornton sits on the northern edge of the Denver metro where dry conditions, steady winds, and sharp seasonal temperature swings put consistent stress on spring steel. Cold winter mornings make the metal brittle and far more prone to snapping, which is why so many local spring failures happen when temperatures drop hardest.

The most obvious sign is a door that will not open at all or feels extremely heavy when lifted manually. You may also hear a loud bang from the garage when the spring snaps, see a visible gap in the torsion spring above the door, or notice the door hanging unevenly on one side. Any of these signs warrants a call to our team before the door is used again.
No. A door with a broken spring puts the full weight of the panels on the opener motor, which it was never designed to carry. The door can drop suddenly without warning and the cables and hardware left under uneven tension are dangerous to handle without proper tools and training. Stop using the door and call us right away.
It is strongly not recommended. Torsion springs store an enormous amount of mechanical energy and can cause serious injury if released incorrectly. Our technicians use specialized tools and calibrate each spring precisely to the door’s weight to handle the replacement safely and correctly the first time.
Yes. Most residential garage doors use two springs installed at the same time that have accumulated the same amount of wear. When one breaks, the other is typically near the end of its service life as well. Replacing both during the same visit saves on a second service call and keeps the door properly balanced.
We replace both torsion springs and extension springs on all major residential garage door makes and models. Our technicians carry both types and can match the correct spring to your specific door and weight requirements during the same visit.
Most standard torsion springs are rated for roughly 10,000 cycles which translates to approximately 7 to 14 years of regular use. Thornton’s dry conditions, steady winds, and sharp seasonal temperature swings can accelerate metal fatigue and shorten spring life, making regular maintenance especially important for local homeowners.
Torsion springs are mounted horizontally above the door opening and work by twisting to store and release energy. They are more common on modern doors and generally offer smoother and quieter operation with a longer lifespan. Extension springs run along the horizontal tracks on either side of the door and stretch to provide counterbalance. They are more common on older door systems.
