BROKEN SPRING SERVICE
Garage Door Spring Repair
We’ll get the door moving safely again.
A broken spring can leave the door stuck, unusually heavy, or too much for the opener to lift. We replace torsion and extension springs with properly matched springs, then check the door’s balance and operation before we leave. Broken spring or unusually heavy door? We’ll install the properly matched spring, balance the door, and test its operation before we leave.

BROKEN SPRING WARNING SIGNS
A Broken Spring Changes How the Door Moves.
A broken garage door spring usually changes the door immediately. You may hear it break, see the coils separate, or notice the door has become far too heavy for the opener to lift normally.
02 SEE IT
A gap between the coils.
On a torsion system, a visible separation is one of the clearest signs.
03 FEEL IT
The door suddenly feels heavy.
Without spring counterbalance, much more of the door’s weight is noticeable.
04 WATCH IT
The opener strains or barely lifts.
The opener may be working—it may be trying to move an unbalanced door.
LOOK UP
The torsion spring is mounted above the door.
VISIBLE BREAK
SEEING ONE OF THESE SIGNS?
Let’s get the spring checked before the door is operated again.
HOW THE SPRING SYSTEM WORKS
The Spring Carries the Weight. The Opener Moves the Door.
The spring system counterbalances the weight of the garage door so it can move smoothly without forcing the opener to lift the full weight. When a spring breaks, that balance disappears. The door can become extremely heavy, and the opener may strain, stop, or lift it only a few inches—even when the opener itself is working.
SPRING
Counterbalances the door.
It offsets the door’s weight before movement begins.OPENER
Moves the balanced door.
It guides normal travel; it should not carry the door’s full weight.HOW THE RIGHT SPRING IS CHOSEN
The Right Spring Has to Match the Door.
Door weight and height, the lift setup, the spring arrangement, and exact spring dimensions all affect how the door balances. A replacement is chosen from the complete system—not from appearance alone.
HIGHER-CYCLE OPTIONS
Longer service life still has to balance the door correctly. A higher-cycle spring may use different dimensions, but the required counterbalance does not change.THE DOOR
Weight and height define the load.
They determine how much force the counterbalance system has to handle.

A Proper Spring Repair Restores the Entire System.
Replacing the broken spring is only part of the job. We check the connected lift hardware, install the properly matched spring system, and verify controlled travel before we leave.
INSPECT
Check the connected lift hardware.
Cables, drums, the torsion shaft, bearings, and door travel are checked for anything else affecting the repair.
MATCH
Select the spring for the actual door.
The replacement must match the door and counterbalance setup—not merely resemble what came off.
BALANCE + TEST
Confirm controlled movement.
We test balance and full travel so the opener is moving a properly counterbalanced door.
SPRING FACTS & SERVICE AREA
Broken Spring? Here’s What Matters.
Straight answers about two-spring systems, safe use, spring types, and where garage door spring repair is available.
TWO-SPRING SYSTEMS If one spring breaks, should both be replaced?
On a two-spring system, both springs should be replaced when one breaks. DASMA recommends replacing both. The replacement spring setup still needs to be properly engineered for that door rather than selected by appearance alone.
SPRING FACT Replace the pair, then match the new spring system to the actual door.
TORSION VS. EXTENSION What is the difference between the two spring systems?
Torsion springs are mounted on a shaft above the door and apply torque through the shaft, cable drums, and lifting cables. Extension springs typically run along the horizontal tracks and stretch and contract as the door moves. Both systems counterbalance the door, but their hardware and repair procedures are different.
SPRING FACT Different spring systems require different hardware, measurements, and repair procedures.
SAFETY Should I keep using the door if a spring is broken?
Stop operating the door and have the spring system inspected and repaired before normal use resumes. A broken spring can leave the door extremely heavy, and weak, broken, or unbalanced springs can allow an open door to fall rapidly or unexpectedly.
SPRING FACT Leave the door closed when possible and do not repeatedly run the opener against a broken spring.
