Doing It Yourself
North Potomac sits six miles out from our shop in Potomac, which matters more for spring jobs than for most calls. A broken torsion spring on a double door is dangerous to touch on any truck's schedule, but it's worse with distance between the diagnosis and the fix - you don't want a tech halfway here only to find out the job needs a part that wasn't on the van.
Spring type questions
We ask a few questions before we leave: single spring or two, torsion or extension, and roughly how old the door is. Most houses in North Potomac went up around 1988, which puts a lot of these doors on torsion springs rather than the older extension-and-pulley setups you'll find on pre-1970s stock closer in.
Torsion not DIY
That's good news - torsion systems are safer to wind and unwind with the right bars, but they are absolutely not a DIY job. A spring under that much tension can break a wrist or worse.
Breaker off, door untouched
If the door won't open and you can see a gap in the coil, close the breaker to the opener, don't force the door by hand, and call. Don't try to lift it past the spring - that's how a cable gets pulled off a drum.
What Is on the Truck
Because the drive out here is six miles, we load for the housing stock we expect to see rather than guessing on site. A 1988-built house in this area typically runs a torsion spring sized for a standard steel sectional door, two-car width, with a single or dual-spring setup depending on whether the builder went heavier for an insulated panel. We carry both wire gauges that cover that range, plus the cable and drum hardware that tends to go next when a spring finally lets go - a snapped spring often takes a cable with it, and showing up without a spare cable means a second trip. We don't stock parts for the much older extension-spring doors still standing in some of the areas we also run, because North Potomac's stock is younger than that; if we're out this way, we're loaded for torsion repair and we check the door's build details on the call before we commit the parts.
How It Shows Up
The symptom in a 1980s-built door is usually sudden, not gradual. The opener strains, the door jerks a few inches and stops, or it won't budge past waist height - classic signs that one torsion spring has snapped and the other is carrying a load it isn't rated for alone.
Winter stiffness stresses springs
In winter, the cold-climate swings around here stiffen the lubricant in the coil and bearing, and that stiffness adds stress to a spring that was already near the end of its winding cycles.
Springs reaching cycle limits
Houses built in this era are old enough now that original springs are hitting or past their expected cycle count, so a bang from the garage on a cold morning isn't random - it's a part reaching the end of its life on schedule.
Where This Job Goes Sideways
Spring repair turns into something bigger when the drums, cables, or the end bearing plate are worn enough that a new spring just stresses the next weak part. On a well-kept 1988 door, that's less common than on older stock - but if the opener has been straining for weeks before the spring finally gave out, the gears inside it may already be chewed up, and that's a separate repair we'll flag rather than bury inside a spring quote. The honest limitation: if the door is original from construction and the track is bent or rusted from decades of use, replacing the spring alone won't fix the real problem, and we'll tell you that instead of charging you twice.
Booking a Visit
We run this job out of Potomac, six miles from North Potomac, so when you call we'll ask for the door's age and symptoms before we load the truck - it saves a second trip and gets the right spring on the van the first time. If you want the fuller rundown on spring repair as a service, that lives on our main page; this one is about how the job runs specifically for the doors out here. See our North Potomac service area page for what else we cover nearby, or the Potomac spring repair page for the service in general.
