Stocked Parts
Lockport's median household income runs about $113,252, well above the $109,064 average across our wider service area, and that shows up in what's hanging over the driveway. Houses here cluster around a 1998 build date, newer than a lot of what we see closer to Joliet, which means double doors are heavier - steel with foam backing instead of thin single-layer panels - and they're carrying torsion springs sized for that extra weight. We keep common torsion spring sizes for 7-foot and 8-foot double doors on the truck because that's what a late-90s build calls for. What we don't keep on hand is anything for a door we haven't seen yet - if your setup turns out to be an odd wind length or a dual-spring extension setup from a remodel, that's a trip back to the shop, not a same-visit fix. We'd rather tell you that up front than pretend every spring is in stock.
What You Pay
At a median income of $113,252, most Lockport homeowners we talk to aren't choosing between fixing the spring and replacing the whole door - the repair pencils out on its own for a 1990s-era door that's otherwise sound. Where it tips toward replacement is age of the opener and the condition of the track, not the spring itself. A door built around 1998 is old enough now that the opener on it may be original too, and a dead opener plus a broken spring on the same visit changes the math. We don't post a flat number here because spring size, door weight, and whether you want one spring or both replaced all move the price - ask for a number when you call and we'll give you one before we start, not after.
How We Fix It
A broken torsion spring on a double door built in the late 1990s has to be matched by wind, wire gauge, and length - guess wrong and the door either won't lift or slams down too fast. We measure the old spring (if there's enough left to measure) or the drum and shaft if it's gone entirely, then install a matched pair rated for the door's actual weight, not a universal size. Winter cold makes this a worse DIY moment than people expect: in our climate band, cold temperatures stiffen the galvanized coating and make a wound spring under tension even less forgiving if the winding bars slip. We balance the door after the spring goes in - lift it by hand to shoulder height and it should hold, not drift up or drop. If it doesn't hold, something else is off and we find that before we leave, not after a callback.
