Garage Door Spring Repair in Longmont
Broken torsion or extension spring? Licensed technicians replace it fast, with guaranteed repairs.
Heard a Bang and Now the Door Won't Open?
That loud bang from the garage was almost certainly a spring. Garage door springs do the heavy lifting. They're wound or stretched to balance the door's weight, so the opener, or your arms, only has to guide it. When a spring breaks, the door suddenly weighs its full 150 to 250 pounds or more, and it won't lift the way it should.
The safest thing you can do is leave it alone. Don't keep pressing the opener button, because it can strip the opener's gears or pull the door off its track. Don't try to lift the door by hand unless you have to, and never try to adjust or wind a spring yourself. Call (720) 698-9749 for a free estimate, and a licensed technician will replace the spring and rebalance the door.
Signs You Need Garage Door Spring Repair
A loud bang from the garage
Torsion springs often break with a sound like a gunshot. Call (720) 698-9749 if you heard one.
The door won't lift or feels very heavy
The opener strains, lifts a few inches and stops, or the door is too heavy to raise by hand.
A visible gap in the spring
Look above the door. A broken torsion spring shows a clear 2-inch gap between coils.
The door slams shut or sits crooked
A weak or broken spring lets the door drop fast or hang lower on one side.
Loose or frayed cables
When a spring fails, its cable often goes slack or jumps off the drum.
The door moves jerkily
Stretched or tired springs make a door shudder, stall or bounce on its way up.

Garage Door Spring Repair: What We Fix
Torsion spring replacement
Most Longmont doors use torsion springs on a bar above the door. We replace them in pairs when it makes sense, so both sides lift evenly.
Extension spring replacement
Older and lighter doors often use extension springs along the side tracks. We replace them with safety cables in place.
Lift cables, drums and bearings
Springs and cables work as a team. We check and replace frayed cables, worn drums and noisy center bearings at the same visit.
Door balance and tune-up
After a spring repair, the door is balanced so it stays put halfway open and lifts smoothly. That takes strain off your opener. Call (720) 698-9749.
High-cycle spring upgrades
Standard springs are built for around 10,000 cycles. If your family uses the garage as the front door, higher-cycle springs last longer. Ask about them when you call.

Why You Shouldn't Replace a Torsion Spring Yourself
A wound torsion spring holds a huge amount of stored energy. Winding bars slip, set screws let go, and cones crack, and when that happens the bar can spin hard enough to break a wrist or worse. Spring injuries send homeowners to the emergency room every year. It isn't worth the savings.
Extension springs carry their own risk. If one snaps without a safety cable running through it, it can fly across the garage. If your door has extension springs with no safety cable, ask about adding one when you call (720) 698-9749.

Spring Repair Questions
How long do garage door springs last?
Standard torsion springs are typically built for about 10,000 open-and-close cycles. Used two to four times a day, that's roughly seven to fourteen years. Higher-cycle springs last longer.
Should both springs be replaced at once?
On a two-spring door, usually yes. Springs wear at the same rate, so when one breaks, the other is often close behind. Replacing both keeps the door balanced.
What's the difference between torsion and extension springs?
Torsion springs sit on a bar above the door and twist to lift it. Extension springs run along the horizontal tracks and stretch. Most newer Longmont homes have torsion springs.
Why do springs break more in winter?
Cold makes spring steel less flexible and makes the opener work harder, so worn springs often give out on cold mornings. Call (720) 698-9749 if yours just did.
