Signs You Need a Garage Door Spring Replacement
Over time, garage door springs experience wear and tear, leading to potential failure. If you notice any of the following issues, it’s time for a replacement garage door spring:
Garage doors won’t open or close properly
If your overhead door struggles to lift or slams shut, the springs may be broken.
Visible damage or gaps in the spring
If the spring appears stretched out, cracked, or broken, it needs immediate replacement.
Loud banging or snapping noises
A sudden break in the torsion spring or extension spring can cause a loud sound.
Uneven or jerky movement
If one side of the garage door moves slower than the other, the spring tension may be off.
Excessive strain on the garage door opener
A broken spring forces the garage door opener to work harder, leading to motor wear and potential damage.
Types of Garage Door Springs We Replace

Extension Springs

High-Cycle Springs

- Built with corrosion-resistant materials like stainless steel and bronze for long-term durability.
