How We Fix It
Most garages in Wolf Trap were built around 1981
Which puts them past the point where builders had settled on two-car bays with wider steel sectional doors - usually 16 feet across on the double bay, hung on a single torsion spring or a pair depending on the door weight. That width matters: a 16-foot door pulls a lot more wire tension than the single-car doors common in older stock, so when a spring lets go, the door doesn't just stick, it can drop hard and fast. We pull the broken spring, measure the wire gauge and wind against the shaft diameter, and replace it with a spring rated for the actual door weight, not a generic swap. If the drums or bearing plate show wear from the old spring's final days, we replace those at the same time rather than send a tech back out in six months. We test the door through a full open-close cycle under its own weight before we call the job done, checking that the cable stays seated at both drums.

We don't carry every spring in the truck for every house on the first trip
If a door uses a less common wind pattern or an older style of drum, we may need to go back out once we've confirmed exactly what's on the shaft.
Why It Happens Here
A torsion spring is rated in cycles, and cycle count depends on how many times a day the door opens and how much weight it's lifting - both of which are higher on the wider doors that went up in Wolf Trap around 1981 than on the narrower single-car doors from earlier building waves. The service area this falls under sees median household income of $143,796, but Wolf Trap itself runs well above that, closer to $250,001, and higher-income households here tend to run two vehicles through a two-car garage daily rather than one. More cycles against a spring rated the same as a lighter door means the spring reaches its fatigue limit sooner.
Cold also plays a part. This region sits in a severe cold climate band, and steel torsion springs lose some flex in hard winter cold, which is when a spring near the end of its cycle life is most likely to snap rather than just get stiff. We see more spring failures called in during and right after cold snaps than in mild weeks.
Time on the Job
A straightforward torsion spring swap on a double door, where the drums and cable are in decent shape, is a job we can usually finish in one visit once we're on site with the correct spring. Wolf Trap is about 6 miles from our shop in Fairfax, so travel out adds a short window before the tech starts - we don't keep a branch or a standing crew in Wolf Trap itself, every job here is dispatched from Fairfax.
If the broken spring has let the door drop off its track, or if a cable has come off a drum under tension, the repair takes longer because we have to re-seat things safely before we can even assess the spring itself. We won't rush that part - a cable under load that's handled wrong is how people get hurt.
Can You Do This Yourself
We'll say this plainly: torsion spring replacement is not a weekend project, and we don't recommend doing it yourself. The spring is wound under several hundred pounds of tension, and the tools to wind and unwind it safely - proper winding bars, a correctly sized socket, a way to hold the shaft steady - aren't things most homeowners have sitting in the garage. People have lost fingers and worse on this exact repair.
What you can safely check yourself: whether the spring is visibly broken (a gap in the coil is easy to spot), whether the door is a single or double bay, and roughly how old the door is. That information helps us bring the right spring on the first trip instead of guessing.
Parts We Carry
For the double-door torsion setups common on Wolf Trap's 1981-built garages, we carry a working stock of standard torsion springs sized for 16-foot steel sectional doors, along with matching drums, lift cables, and bearing plates. What we can't promise is same-day stock on less common setups - older single-spring configurations paired with non-standard shaft diameters, or doors that have been retrofitted with a different spring system than they came with originally. On those, we confirm the exact spec on site, then order if it's not something we're already carrying. We'd rather tell you that up front than promise a part we don't have in the truck.
