Watch-outs

The Complications

Most of Cedar Mill went up around 1992, which puts a lot of original torsion spring assemblies at roughly thirty years of cycles. That's not a random number - it's close to the design life for the steel wound springs that shipped standard on doors from that era.

Cycle count fatigue

The spring itself doesn't care how well the door was maintained; it cares how many times it's been wound and unwound, and three decades of daily use adds up fast.

Damp garage coating wear

The cold moderate climate out here doesn't help. Springs live in a garage that isn't heated or sealed, and the swing between damp winter air and dry summer heat works on the galvanized coating over time.

Hairline cone cracks

Once that coating pits, rust gets into the coil itself, and a spring that looks fine from the ground can be down to a hairline crack at the winding cone. We see this pattern often enough in houses from this build window that it's the first thing we check, not the opener or the track.

Symptoms

The Symptom

Serving Tualatin, OR

The giveaway is usually sudden. The door was working, and then it isn't - it won't lift past a few inches, or it drops faster than it should when you try to close it by hand. Some owners hear a loud bang from the garage first, a sound like a gunshot, which is the spring letting go under tension. Others just notice the door feels twice as heavy as it used to, because one spring is doing the work of two.

A cable going slack on one side, or the door sitting crooked in the opening, points the same direction. None of these are opener problems, even though the opener usually gets blamed first because it's the part people can see move. If your door is from the original build and you haven't touched the springs since, age is the simplest explanation and usually the right one.

Our process

How We Fix It

We replace both torsion springs as a pair, even if only one has failed - the other is on the same clock and close behind.

Matching spring to weight

We match the spring to the door's weight and the drum size on the shaft rather than swapping in whatever's closest, which is where a lot of bad fixes come from.
Full-cycle balance test

The door gets balanced and tested through a full cycle before we call the job done. Here's the honest limit: some odd or oversized spring diameters used on heavier insulated doors aren't something we carry on the truck, and those can mean a short wait on parts.
No local Cedar Mill stock

We'll tell you on the spot if that's the case rather than guess and come back twice. We're driving out from Tualatin for every call here, so we don't keep stock at a Cedar Mill location - just what's loaded for the day's route.

Booking

How to Book

Cedar Mill sits about 11 miles from our shop in Tualatin, and spring jobs go on the same route as everything else we run that direction. Call and describe what you're hearing or seeing - a bang, a heavy door, a cable hanging loose - and we'll get a sense of whether it's a spring before the truck even leaves. See our Cedar Mill service area page for what else we cover nearby, or check the Tualatin spring repair page for how we handle this job more broadly.

Questions

Common questions

Why did my spring break with no warning?

Torsion springs fail from metal fatigue, not from a single event, so there's rarely warning. A spring installed when a house was built in the early 1990s has usually logged close to its full cycle life by now. It can hold fine for years and then let go on an ordinary morning - that's how fatigue failure works.

Can I just replace the one spring that broke?

You can, but we don't recommend it. If your doors are original to a build around 1992, the second spring is the same age and has seen the same cycles. Replacing one and leaving the other means a mismatched pair and a second failure within a short stretch, so we replace both together.

Do you keep spring stock in Cedar Mill?

No. We run out of Tualatin, about 11 miles away, and carry common spring sizes on the truck for same-route jobs. If your door needs an uncommon spring diameter, we'll say so upfront rather than guess, and that can mean a short wait on the part.
