Extension Spring Replacement in Arlington, TX
Extension springs run horizontally along the upper tracks on each side of the door opening and stretch under tension as the door closes, then release that energy to help lift the door back up. They're common on lighter single-car doors and older residential installations. Unlike torsion springs, extension springs work as a pair — when one fails, the other is usually not far behind.

When to Call
When You Need Extension Spring Replacement
- One side of the door drops faster than the other when closing
- You see a spring hanging loose or stretched out along the side track
- The door opens unevenly and the opener strains audibly on the way up
- A safety cable inside the spring is the only thing holding a broken coil in place
- Your single-car garage door was built before 1995 and has never had spring work
- The door slams down faster than normal when you release it manually
How It Works
Our Process for Extension Spring Replacement
- 1
Initial call
We ask about door size and whether you can see both springs. Extension spring systems vary by door weight and track configuration, and we want the right parts before arriving.
- 2
Inspect both springs and safety cables
We look at both springs even if only one is visibly broken. We also check the safety cables threaded through each spring — a missing cable turns a broken spring into a projectile.
- 3
Release tension and remove old springs
We open the door fully to release spring tension before disconnecting anything. Extension springs are removed from their S-hooks and pulley attachments in a specific order to stay safe.
- 4
Install matched replacement springs
We install both springs as a matched pair, sized by door weight. Mixing old and new springs creates uneven tension and accelerates failure on the newer spring.
- 5
Check and replace safety cables if needed
Safety cables are inspected for fraying. If they're damaged or missing, we replace them. This is not optional — it's a basic safety requirement.
- 6
Test door travel and balance
We cycle the door several times manually and with the opener, watching for even travel, smooth pulleys, and proper speed throughout the opening arc.
What's included
- Replacement of both extension springs as a matched pair, not just the broken one
- Inspection and replacement of safety cables if frayed, missing, or undersized
- Pulley inspection and lubrication as part of the installation
- Door travel test to confirm even lift on both sides
- Opener cycle test with limit and force settings checked before completion
- Honest assessment of whether the door is a better candidate for a torsion conversion
What's not included
- Conversion from extension springs to a torsion system — that's a separate, larger job
- Track repairs if the uneven travel was caused by bent or misaligned track sections
- Opener motor repairs if the opener was damaged by extended operation under a failing spring
Real Situations
Common Scenarios in Arlington
A homeowner in an older Arlington neighborhood has a detached single-car garage built in the late 1980s with original hardware still in place.
Springs this age are well past their expected service life. We replace both springs and the safety cables, and we'll be direct about whether the pulley hardware is worth keeping or needs to go. Older systems sometimes have undersized cables that don't meet current safety expectations.
A tenant calls a landlord after the garage door suddenly fell fast and loud, and a broken spring is visible hanging off the track.
A fast-falling door with no spring resistance is a safety issue. We treat it as urgent. We replace both springs, verify the safety cables are intact and properly routed, and test that the door decelerates correctly through the full close cycle.
A homeowner replaced one extension spring themselves six months ago and now the other one has snapped.
Single-spring replacements create a mismatch in tension and load distribution, which shortens the life of the newer spring. We replace both again as a matched pair and explain why matching them matters. We don't charge extra for the repeat visit — it's a common situation.
Arlington Context
Why this matters in Arlington
A lot of Arlington's older neighborhoods — particularly areas developed in the 1970s through early 1990s around Districts 2 and 6 — have detached garages with single-car doors still running original extension spring hardware. These systems were built to much lower cycle ratings than what's available today. The heat in North Texas also dries out pulley bearings faster than in cooler climates, which puts more load on the springs themselves over time.
Straight Talk
About pricing & scope
Extension spring cost depends on the door's weight and the spring's stretch length and wire diameter. If the pulleys are worn or the safety cables are the old thin-gauge type, adding those parts changes the final number. We'll tell you what we see when we're on-site before we add anything to the work order.
