Why This Fails Locally
Portsmouth's median household income of $58,972 runs well below the $90,885 median across the wider service area, which is part of why we lead with the repair-or-replace math instead of assuming a full door swap. On an older door, swapping just the spring is usually the right call financially, but only if the rest of the hardware - drums, bearing plates, the track - isn't also at the end of its life. Replacing a spring on a door whose track is already bent just moves the failure point.\n\nAt 13 miles from Hampton, this is one of the longer hauls in the service area, so we quote the spring size and door weight over the phone before loading the truck, rather than diagnosing on arrival and adding a second trip. That's not a complaint about distance, it's just how the math works when you're not based in town. With roughly 39,678 households in Portsmouth against 52,311 across the whole area, this suburb carries a meaningful share of the territory's housing stock, and most of it was built in the same narrow window, which means a lot of these springs are aging out at roughly the same time.
Parts We Carry
We stock standard torsion springs in the common wire sizes and lengths used on single and double doors, plus extension springs for the older lift-style setups that some of these 1966-era builds still run. Doors on these 1966-era builds often run EZ-set or early torsion conversions that newer stock skips entirely, so when we get a call on one of those, we bring options rather than a single fixed part.\n\nHere's the honest limit: a handful of these doors have wind cones, drum sizes, or shaft diameters that are genuinely obsolete, not just old-fashioned, and parts for those aren't something we keep on the truck. If we hit one of those, we'll tell you straight that it's a special-order item, give you the lead time, and let you decide whether to wait on the exact match or move to a standard-size replacement that fits the opening. We'd rather say that up front than quote a job we can't finish that day.
The Symptom
Most calls start the same way: the door won't open, or it opens a few inches and the opener strains like it's lifting something heavier than it should. Sometimes it's a loud bang from the garage, usually mid-morning when the metal has had time to flex with temperature change overnight, and after that bang the door either won't move at all or slams down hard when someone tries to close it manually.\n\nA door that drops fast instead of settling is the clearest sign of a snapped spring, not a bad opener. Pulling the manual release and lifting the door by hand will tell you fast - if it feels like dead weight instead of a balanced lift, the spring's gone, and running the opener against that weight repeatedly is how you also burn out the motor.
