Extension Spring Replacement in South Glens Falls, NY
Extension springs run above the horizontal tracks on either side of the door and stretch — rather than twist — to store lifting energy. They’re common on older garage doors and lighter-duty installations.
Local context for South Glens Falls
Homes in and around South Glens Falls face a genuine cold-weather climate pattern where winter conditions materially affect garage door spring performance and failure risk.
Extension spring systems use a spring mounted above each horizontal track that stretches as the door closes and contracts to help lift the door as it opens, working through a pulley-and-cable system that redirects the force downward to the door itself. This design was the standard for decades before torsion systems became more common, and it’s still found on many older homes and some lighter residential doors today.
Because an extension spring stores energy by stretching rather than twisting on a fixed shaft, a snapped extension spring can become a projectile if it isn’t restrained — which is exactly why safety cables (a thin cable that runs through the center of the spring, anchored at both ends) are considered essential on any extension-spring door. A door with extension springs but no visible safety cables is a real hazard and worth flagging to a technician even before a spring actually fails.
Extension Spring Replacement problems we see in South Glens Falls
Ice and snow interference near the spring assembly
Accumulated ice or snow at the base of the door can add extra resistance the spring has to work against, a common winter service call.
Cable strain in freezing temperatures
Cold can thicken cable lubricant and add strain at the drum, sometimes contributing to fraying on the coldest days.
No visible safety cable through the spring
A missing safety cable means a snapped extension spring has nothing to restrain it, creating a real projectile hazard — this should be corrected regardless of whether the spring has failed yet.
Uneven lift, heavier on one side
When only one of two extension springs fails or weakens, the door often lifts unevenly or binds against the track on that side.
Frequently asked questions
Should garage door springs be inspected before winter in South Glens Falls?
A pre-winter inspection can catch early spring wear before sustained cold in and around South Glens Falls turns a minor issue into a fully broken spring and a stuck door.
How do I know if my garage door has torsion or extension springs?
Torsion springs are mounted on a horizontal shaft directly above the closed door. Extension springs run above the horizontal tracks on either side of the door, roughly parallel to the ceiling. If you see long springs running along the tracks rather than a single shaft above the door, it’s an extension system.
Are extension springs less safe than torsion springs?
Extension springs aren’t inherently unsafe, but they do carry a specific risk if safety cables are missing: a snapped extension spring under tension can become a projectile. With properly installed safety cables, extension systems are a well-established, functional design that’s simply less common on newer doors than torsion systems.
