An extension spring stores its force by stretching, and a snapped one can whip hard enough to break a window or injure anyone near it. The safety cable through the spring limits that only while it stays intact.

Extension Spring Repair in Carrollton, TX
One of the long springs beside your garage door's horizontal track hangs slack, has stretched out of shape, or snapped and now dangles from its safety cable. Extension spring repair brings back the stretch that lifts each side of the door, and until both sides match, your door rises crooked or not at all. Keep the door still, keep people and cars clear, and call about the extension spring in your Carrollton garage.
What you are seeing
Trouble along the tracks
Extension springs stretch along each side of your garage ceiling, parallel to the horizontal tracks, and pull the door up through a set of pulleys. Faults show on one side first.
- Slack spring by the track
A spring that once sat taut hangs loose with your door closed.
- Open coils at rest
Coils that stay apart with the door down mark a spring stretched past its limit.
- One side lagging
The weak spring's side trails, so your door climbs at an angle.
- Spring hanging on its cable
A snapped spring dangles from the safety cable threaded through it.
Keep the door down and the bay clear, then call while one side spring still holds.
(972) 634-8789Safety protocol
Stay clear of the spring and the pulleys
Stop running your door, keep children, pets and cars out of the garage bay, and leave the springs, pulleys and cables alone. If a spring or the door has hurt someone, call 911 first.
Loss risk
What a weak side does to your door
With one extension spring short of its stretch, the strong side pulls ahead and your door racks in its tracks. Every cycle grinds rollers against the rail and loads the opener unevenly.
- Racked sections
The door twists between its sides and strains the hinges.
- Roller wear
Rollers on the lagging side drag in the track.
- Pulley damage
A worn sheave frays the cable that runs over it.
- Missing safety cable
Without one, the next spring break can throw metal across your garage.
Property type
Extension springs or a torsion spring
Extension springs run beside the horizontal tracks, one per side, and stretch as your door closes. A torsion spring sits on a single shaft above the opening and twists instead, so a spring that broke on the shaft overhead needs broken torsion spring repair rather than side-mounted work.
Repair scope
What extension spring repair covers
Extension spring repair treats both sides of your door as one system, because a door only rises straight when its springs match.
- Matched pair
Both springs change together, rated for your door's weight, so neither side lags.
- Safety cables
A cable runs through each spring and anchors at both ends to contain a future break.
- Pulleys and sheaves
Worn pulleys come out before they fray the lift cables.
- Track and rollers
The lagging side's rollers and rail show whether the uneven pull bent anything.
Local detail
A crooked door in a busy Carrollton garage
A door that climbs at an angle drags its rollers every time you leave or come home. Calling about the slack side before it snaps keeps your Carrollton repair to springs and pulleys.

Triage order
Why the side spring needs a call now
A door pulled up by one good spring runs crooked, and each crooked trip bends rollers and racks the sections. Extension spring repair stays a side-spring job only while your door still travels in its tracks.
Call from Carrollton or a Dallas County suburb next door while the door rests closed and the other spring still holds.

Common questions
Side-mounted springs in Carrollton: common concerns
What is the cable running through my extension spring?
A safety cable. It holds a snapped spring in place so the pieces can't fly across your garage, which is why a missing one adds to the risk.
Can one extension spring change without the other?
It can, but the new one pulls harder than the old one, so your door runs crooked. Matched pairs keep both sides level.
Why does my door rise at an angle?
One extension spring has lost stretch, so its side lifts less. Stop using the door and keep clear until both sides match again.
A door held by a broken spring is a door waiting to drop.
Call from Carrollton before a broken spring or cable strips the opener or bends the sections.
