Extension Spring Replacement in Minneapolis, MN
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 Minneapolis
The Twin Cities experience some of the most extreme winter cold of any major metro area in the continental United States, with regular stretches well below 0°F and significant snowfall most winters. This is not a mild cold-weather market — it’s one of the most demanding climates nationally for garage door springs, and cold-related spring failure is a routine, expected part of the Minneapolis winter service calendar rather than an occasional event.
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 Minneapolis
Proactive pre-winter spring replacement
Given how cold Twin Cities winters get, many homeowners choose to replace an aging spring proactively before winter rather than risk a mid-cold-snap failure.
Aging springs in established housing
The Twin Cities’ substantial older housing stock means many torsion spring systems are original, multi-decade-old equipment.
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.
Rust or corrosion along the spring coils
Extension springs mounted near the tracks are exposed to more moisture and debris than shaft-mounted torsion springs, making corrosion a common failure driver.
Frequently asked questions
How extreme does Minneapolis winter cold get for garage door springs?
Minneapolis winters are among the coldest of any major U.S. metro, with regular stretches well below 0°F — making cold-related spring failure a routine, expected part of the local winter service pattern rather than an occasional event.
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.
