Dead weight release cord
If you pull the release cord and try to lift it by hand and it feels like dead weight, that's a broken torsion spring, full stop - nothing else makes a double-car door feel that heavy that fast. Sometimes it's less dramatic.
Damascus, Tualatin
Damascus homes run a few years older than the average across our service area, which means different torsion hardware. We drive out from Tualatin, 16 miles, to fix it.
Local causes
Most of the garage doors we see on spring calls out here come off houses built around 1978 - a couple years ahead of the 1980 median for the wider area we cover out of Tualatin. That gap matters more than it sounds like it should. A door installed in the late '70s is more likely to be running the older style torsion spring, mounted on a shaft that wasn't sized the same way manufacturers started sizing them through the 1980s and '90s. The springs themselves have usually been replaced once or twice by now, but the drum and shaft underneath often haven't, and that's the part that tells us what we're dealing with before we even get the door open.
Damascus sits about 16 miles out from our shop in Tualatin, so every call here is a planned drive, not a drop-by. We still see the same winter pattern as the rest of the area - cold, damp stretches that stiffen old lubricant and make a spring that's already fatigued finally let go on a morning you didn't expect it to. The age of the door and the weather both play a part, but the age is the one that decides what parts we're bringing with us.
Symptoms
The door won't lift, or it lifts about six inches and stops, or the opener motor strains and clicks without moving the door at all.
If you pull the release cord and try to lift it by hand and it feels like dead weight, that's a broken torsion spring, full stop - nothing else makes a double-car door feel that heavy that fast. Sometimes it's less dramatic.
A loud bang from the garage, usually noticed from inside the house, is the spring letting go on its own, not during use. If that happened and the door still opens with the opener, you likely have a two-spring setup and only one side failed - the door will feel crooked or lift unevenly until both sides are matched.
On older torsion setups like the ones common to 1978-era Damascus houses, a mismatched spring replacement is a common mistake from past repairs, and it shows up as a door that tracks fine going up but shudders coming down.
On the truck
For the older torsion shaft setups that show up more often on Damascus's slightly earlier-built stock, we carry standard wind and dual-wind torsion springs in the sizes that fit pre-1980s drum and shaft combinations, not just the newer cable-drum assemblies that became common through the '80s and '90s. We also keep standard cable, bearing plates, and center brackets on the truck, since those parts fail alongside an old spring more often than homeowners expect.
Here's the honest limit: if the drum or shaft itself is pitted or bent - which happens on doors this age when a spring has been running unbalanced for a while - we may not have that exact replacement part on hand. Older shaft diameters aren't all stocked the same way modern parts are, and if yours is a less common size we'll need to order it rather than finish the job same-visit. We'll tell you on site if that's the case before we start, not after.
Pricing
We don't publish a flat number here because the job itself varies with what's actually on the door - a single standard torsion spring replacement costs less than a dual-spring job on a heavier insulated door, and both cost less than a job where the drum or shaft also needs replacing.
What we can tell you is that houses built around 1978, which is most of what we see in Damascus, more often need the drum and bearing checked along with the spring, simply because that hardware has had forty-plus years to wear rather than the twenty or thirty on a newer door.
Given the median household income here runs well above the broader service area's $101,953, we don't assume cost is the deciding factor on whether to fix or replace - but we'll still tell you straight if a door's hardware is worn enough that a repair now just buys you the same call again in a year or two.
Our process
We unwind the old spring under clamp, pull the broken half off the shaft, and check the drum and bearing plates before anything new goes on - on a door this age, skipping that check is how a repair fails again in six months. If the shaft is straight and the drums aren't worn, we set the new spring to match the door's weight and winding, adjust tension by hand, and run the door through a full cycle to balance it before we call the job done.
We come from Tualatin for every Damascus call, so there's no local branch to swing by if something feels off after we leave - we ask you to walk through the door with us before we pack up, so any adjustment happens on that same visit rather than a second trip.
Questions
Houses here run a median build year of 1978, a couple years ahead of the 1980 median across our wider service area. Older torsion shafts and drums were sized differently than later ones, so the spring that fits a 1978 door isn't always the same part that fits a 1995 one. We bring both sizes when we can, but we check the shaft on site first.
No. We're based in Tualatin, about 16 miles away, and every Damascus call is a planned drive from there. We don't claim a local depot or a guaranteed same-day window for the area - we schedule the trip and confirm the time with you before we head out.
Yes, if it's left broken and someone keeps running the opener anyway. The opener motor isn't built to lift the door's full weight alone, and forcing it can burn out the motor or strip the drive gear. Once a spring breaks, stop using the opener until it's fixed.
Usually, yes - we stock standard torsion springs, cable, and bearing plates for the shaft sizes common to houses built through the 1980s and 90s, which covers most of Damascus. If a drum or shaft is bent or an unusual size, we may need to order it rather than finish same-visit, and we'll tell you that before starting.
