Extension Spring Replacement Dallas
Contact us to discuss your service needs. Same-day appointments may be available, subject to scheduling.
Extension springs run along the horizontal tracks on either side of your door. As the door closes they stretch, and as it opens they contract to help lift it. They are common in older Dallas homes, especially in Oak Cliff and East Dallas.
When an extension spring breaks, the door often hangs crooked, feels extremely heavy on one side, or will not stay open. Because these springs stretch under tension, a broken one without a safety cable can be dangerous — which is why we always fit safety cables with new extension springs.
Our Dallas extension spring service includes matched spring pairs, new safety cables, pulley and cable checks, and a full balance test. We also lubricate the tracks and rollers so the door runs quietly.

The Tools We Use — And Why They Matter
Garage door springs store an enormous amount of tension. A DIY job with the wrong tool is how people get hurt. Our technicians carry professional, job-specific tools on every van, so the repair is safe, precise and built to last.
| Tool | What it does | Why it matters for your door |
|---|---|---|
| Winding bars (solid steel) | Wind and unwind torsion springs in controlled quarter-turns | Prevents the spring slipping and causing injury; gives exact tension |
| Vise grips / locking pliers | Lock the torsion shaft so it cannot spin during work | Keeps the door and technician safe while springs are under load |
| Socket & wrench set | Remove and refit brackets, drums, bearings and centre plates | Avoids rounded bolts and loose fittings that cause future failure |
| Spring size gauge & calipers | Measure wire size, inside diameter and spring length | Ensures the replacement spring matches your door weight exactly |
| Cable puller & drum tool | Seat lift cables correctly on the drums | Stops cables jumping off and the door hanging unevenly |
| Step ladder & safety glasses / gloves | Safe access to the header and protection from metal parts | Professional safety on every job, no shortcuts |
| Silicone-based garage lubricant | Lubricate springs, rollers, hinges and tracks | Quieter operation and longer spring life |
We never use screwdrivers as winding bars, and we never re-use a visibly cracked or rusted spring. If a part is worn, we tell you before we replace it.
Before & After: Real Spring Repair Work
Most Dallas doors we see have one broken spring, a door that hangs crooked, or an opener straining to lift a door it was never meant to lift alone. Here is the difference a correct spring makes.

Frequently Asked Questions
Are extension springs dangerous?
They can be if they break without a safety cable. That is why safety cables are now standard on our replacements.
How long do extension springs last?
Typically 7–10 years or around 10,000 cycles, depending on use and maintenance. Rust and lack of lubrication shorten life.
Can I replace just one extension spring?
We recommend pairs — uneven tension makes the door run crooked and wears the opener.
Door stuck? Spring snapped? Don't force it.
A broken spring makes your door dangerously heavy. Leave it closed, unplug the opener, and call us — same-day appointments may be available, subject to scheduling.
