What to expect with extension spring service
Extension springs run along the horizontal tracks on each side of your door. Here is what failure looks like and how we fix it.
What extension springs look like when they fail
Extension springs run along the horizontal tracks above your door. When one snaps you'll find a visible gap in the coil or the spring hanging loose on one side. The door will feel impossibly heavy on that side and the opener may struggle or trip the breaker.
We carry the right spring sizes on every truck so same-day replacement is the standard, not the exception.
Balance testing protects your opener and tracks
After replacing both springs we perform a lift-and-hold balance test at the midpoint. A properly balanced door stays level when released. An unbalanced door strains the opener motor and can cause rollers to bind in the track over time.
If your door has been unbalanced for a while, see our roller replacement page to make sure no track damage occurred.
Why extension springs require professional tools
Extension springs store considerable energy in their stretched state. Releasing or installing them without the right winding bars and safety clamps risks violent spring whip. Our technicians use manufacturer-certified tools and carry $2 million liability insurance.
Considering an upgrade? Many single-car garage doors can convert to a torsion spring system for smoother, longer-lasting operation. Ask us during service.

How extension spring replacement works
From your call to a balanced, working door - here is what to expect.
Call us
Describe your situation. We'll confirm the spring type, give you upfront pricing, and dispatch a tech with the right springs on their truck.
We replace both springs
Both extension springs come out together - one failure means the other is not far behind. New 10,000-cycle springs go in with safety cables threaded through the centers.
Balance test and done
We set equal tension on both sides, perform a lift-and-hold balance test, and verify the safety sensors and opener function correctly. Usually 30-45 minutes total.
Extension spring questions answered
How long do extension springs last?
Extension springs typically last 7,000-10,000 cycles (5-7 years with average use). They have a shorter lifespan than torsion springs due to the stretching motion and exposed position along the tracks.
What are safety cables and do I need them?
Safety cables are steel cables running through the center of extension springs. If a spring breaks, the cable prevents the spring from flying across the garage. Safety cables are required by building codes and included with all our extension spring replacements.
Should I replace both extension springs?
Yes, always replace both springs even if only one broke. Springs installed together wear at similar rates and the second spring will likely fail soon. Replacing both ensures balanced operation and prevents a second service call.
Can I upgrade from extension springs to torsion springs?
Yes, upgrading from extension springs to torsion springs is possible but requires additional hardware and labor. Torsion springs last longer and provide smoother operation. We can evaluate your door and provide upgrade pricing during service.
How can I tell if my extension springs need replacement?
Look for visible gaps in the spring coils, rust, stretched appearance, or uneven door operation. If your door opens unevenly, struggles to lift, or you hear squeaking from the springs, replacement is likely needed soon.
How do I get a quote for extension spring replacement?
Extension spring replacement is generally less complex than torsion spring work. Call us for a quote specific to your door. We always include safety cables in the replacement.
