Broken Spring Repair for Wilsonville Garage Doors

Stocked Parts

We carry torsion springs in the wire sizes that show up again and again on houses built from the mid-1960s through the late 1990s, since that's the bulk of what's standing in this service area. Most of what we pull off doors here is a standard torsion spring on a single center shaft, sized for a 7-foot or 16-foot door, not the odd extension-spring setups you find on much older construction. We keep common end bearing plates, cable drums, and winding bars with us on the truck, because a spring job that turns into a second trip costs the homeowner a day waiting on an open door.

What we don't stock on the truck is anything custom - oversized commercial shafts, discontinued opener-integrated spring assemblies, or odd imported hardware from a door brand that stopped making parts years ago. If your door falls into that category, we'll tell you straight that it may take a special order, and we'd rather say that up front than pretend we can fix it on the first visit. For the typical torsion setup on a typical Wilsonville garage, we're usually in and out with the part already in hand.

Why It Happens Here

A torsion spring is rated for a set number of open-close cycles, and that number doesn't care what year it is - it just counts. Housing in this service area is mostly 1960s-70s stock, with the broader range running 1964 to 1997 and a median build year around 1978. That means a lot of original springs, or at best one replacement generation back, are well past the point where the steel has lost its temper.

The climate band here is cold-moderate, which matters more than people think. Steel contracts in cold weather, and a spring that's already fatigued from decades of cycling loses tension faster when overnight temperatures keep dropping and climbing through the winter months. That's a different failure pattern than a mild coastal climate, where springs can limp along longer before they give out. In a cold-moderate band, the last few winters before a spring finally snaps usually come with warning signs - slow lift, uneven travel, a door that drifts down on its own. By the time it breaks outright, it's usually because nobody caught those signs in time.

What You Are Seeing

The classic sign is a door that won't budge, or one that the opener strains against and then stops. If you look at the spring above the door and see a visible gap in the coil, that's a torsion spring that's already broken - don't try to force the door open or closed with the opener, since the opener was never meant to lift the door's full weight on its own.

A less obvious sign is a door that closes unevenly, dropping faster on one side, which usually means one spring is still intact and the other has lost tension but hasn't snapped yet. You might also hear a loud bang from the garage - that's often the sound of the spring letting go. Cables that look frayed or kinked near the bottom bracket are a related issue worth mentioning in the same call, since a worn spring puts extra load on the cables that are already doing more work than they should.

How We Fix It

We replace springs in pairs on most doors, even when only one has failed, because a spring that's had the same cycle count as its matching pair is close behind it. Trying to save money by replacing just the broken one usually means a second service call within a year or two. Given the median household income of $101,462 across this service area, most owners we talk to would rather handle both springs once and be done with it than pay for two separate visits.

On arrival we check the door's weight and the drum size to match spring wire diameter and length correctly - a spring that's close but not exact will either strain the opener or wear out early. We re-torque against a locked door, test the balance by hand before reconnecting the opener, and check that the cables and bottom brackets aren't carrying damage from the failed spring. If the door is older and the track or rollers are also worn, we'll flag that separately rather than bundle it into the spring job without asking first.
