Garage Door Extension Spring Replacement in Glendale, CA
Extension springs run along the horizontal tracks on either side of your garage door and stretch under tension as the door closes. They're common on older single-car doors and lower-headroom garages. When one snaps, the door drops on that side and becomes crooked or completely stuck. Unlike torsion springs, extension springs also require intact safety cables running through them — if those cables are missing or frayed, a snapped spring becomes a projectile.

When to Call
When You Need Garage Door Extension Spring Replacement
- One side of your garage door dropped lower than the other side suddenly.

- The door moves but wobbles unevenly and scrapes the side of the frame.
How It Works
Our Process for Garage Door Extension Spring Replacement
- 1
Assess Both Springs and Safety Cables
We inspect both springs even if only one failed, and check that safety containment cables are intact and correctly routed.
- 2
Release Tension Safely
We disconnect the opener and relieve tension before touching the spring hardware to prevent uncontrolled snap-back.
- 3
Match and Install Replacement Springs
Springs are matched by length, wire diameter, and extension to your specific door weight — not swapped with whatever's on the truck.
- 4
Test Balance and Travel
We run the door through several full open-and-close cycles and check that both sides lift evenly without binding.
Glendale Context
Why this matters in Glendale
Older Glendale homes built before 1980 frequently have low-headroom garages where extension spring systems were standard. Many of those springs have never been replaced and are well past their expected cycle count.
Straight Talk
About pricing & scope
We almost always recommend replacing both springs at the same time. If one failed, the other is at a similar point in its lifespan. Replacing both now costs less than two separate service calls.
