Extension Spring Replacement in Garland, TX
Extension springs run along the horizontal tracks on each side of the door and stretch to store energy as the door closes. They're common on older Garland homes with lower garage ceilings where torsion spring hardware won't fit. Because they work under full stretch tension, a broken extension spring releases fast and the safety cable running through the spring is what keeps the pieces contained.

When to Call
When You Need Extension Spring Replacement
- Spring on one side of the door is visibly snapped or dangling loose
- Door rises unevenly — one side higher than the other when opening
- You have a single-car door built in the 1970s or 1980s with springs on the sides
- The door slams down instead of closing smoothly and the spring looks thin or stretched
- Pulley at the end of the track is bent or the cable has come off on one side
- You're replacing an older door and need to match the spring setup for the existing tracks
How It Works
Our Process for Extension Spring Replacement
- 1
System Identification
We confirm whether the door uses an extension spring system and check for safety cables inside the springs. Missing safety cables are a hazard we flag before anything else.
- 2
Tension Assessment
We open the door fully to release spring tension before removal. Extension springs are safest to work on when the door is in the open position and the spring is at rest.
- 3
Spring and Hardware Inspection
We check the pulleys, S-hooks, and the connecting cables on both sides. A broken extension spring often damages the pulley it runs through or pulls the S-hook loose.
- 4
Spring Sizing
Extension springs are sized by door weight and height. We measure or weigh the door to confirm the right spring stretch length and weight rating before installing.
- 5
Replacement and Cable Check
We replace the spring on the failed side and inspect the opposite spring. We also verify or install safety cables through both springs — that's non-negotiable on this type of system.
- 6
Balance and Cycle Test
We test door balance with the opener disconnected and run multiple powered cycles to check that both sides travel evenly and the door doesn't pull to one side.
What's included
- Identification of correct spring size and weight rating for your door
- Removal of the failed spring with door in safe open position
- Installation of replacement spring on the affected side
- Inspection of pulleys, S-hooks, and lift cables on both sides
- Safety cable installation through both springs if not already present
What's not included
- Replacement of the opposite spring unless it's also failed or visibly compromised
- Pulley or cable replacement if those are damaged — quoted separately after inspection
- Conversion from extension springs to torsion springs — that's a separate service and scope
Real Situations
Common Scenarios in Garland
A homeowner near downtown Garland has a 1970s single-car garage with the original extension springs — one snapped and put a hole in the drywall.
Extension springs without safety cables can do real damage when they let go. We replace the broken spring, install safety cables through both springs, and inspect the pulleys since hardware that age is often worn. We're honest if the system is at the point where parts are hard to source.
A homeowner in East Garland notices his door opens higher on the left than the right and the opener is pulling hard.
Uneven opening usually means one spring has stretched beyond its working range or has partial coil failure. We compare tension on both sides, replace the weaker spring, and adjust until the door travels level. We also check whether the cable lengths are equal on both sides.
A homeowner is buying an older home in South Garland and the inspection report says both extension springs are original and should be replaced.
We replace both springs since they've had the same wear history. We also assess whether the ceiling height would allow a torsion conversion, which we explain as an option — not a sales pitch. Extension springs work fine when they're properly maintained and safety cabled.
Garland Context
Why this matters in Garland
Extension spring systems are more common in Garland's older stock — particularly the single-car garages attached to ranch-style homes built before 1985. Ceiling height in those garages is often too low for standard torsion hardware, so extension springs are what made sense at the time and what's still in place. The heat and humidity here accelerate corrosion on the S-hooks and pulley hardware, which is often the first thing to fail even when the spring itself looks okay.
Straight Talk
About pricing & scope
Extension spring pricing depends on spring size, how many need replacement, and whether pulleys or cables need work at the same time. If safety cables aren't present, we include them — that's not optional given the risk of a loose spring under tension. We explain what we find before we add anything to the scope.
