Signs of spring failure
Signs You May Have a Broken Garage Door Spring
A failed or worn spring can make the door unsafe, unusually heavy or impossible to operate correctly.
Door Feels Very Heavy
Without proper spring support, the full weight of the garage door becomes difficult and unsafe to lift.
Request extension spring service
Door Opens Only a Few Inches
The opener may begin lifting the door but stop because the spring is no longer counterbalancing its weight.
Schedule a spring inspection
Loose Cables or Crooked Movement
A spring failure can release cable tension and cause uneven or unsafe door movement.

Frequently asked questions
Garage Door Spring Replacement FAQ
Do you repair or replace a broken spring?
A broken garage door spring is replaced rather than patched. After replacement, the door is balanced and tested for proper operation.
Do you replace torsion springs and garage extension springs?
Yes. We inspect the door and lifting system, identify the correct spring type and specification, explain the recommended work and replace the approved torsion or extension spring system.
Should both springs be replaced if only one is broken?
When a door uses two matched springs, both springs have normally completed the same number of cycles. The technician will inspect the system and explain the appropriate replacement option before work begins.
Can I continue using the opener with a broken spring?
Do not continue operating the door. A broken spring can make the door extremely heavy and place additional load on the opener and other components.
Is same-day service available?
Same-day service may be available depending on technician routing, current workload, property location and parts availability. Call for the current service window.
How much will the repair cost?
Cost depends on the spring system, door size and weight, number of springs and condition of related components. The recommended work and price are explained before chargeable work begins.
What areas do you serve?
