Mount Prospect, Evanston
Torsion spring repair for Mount Prospect's 22,003 households, mostly built after 1969 - later hardware than the rest of Evanston's service area. We drive the 12 miles out.

DIY or pro
A torsion spring holds the full weight of the door under tension, and it's wound to do that with a bar and a couple of winding cones - not a screwdriver you found in the drawer.
We're not going to pretend this is a job you talk yourself through on a Saturday afternoon, because the failure mode isn't a scratched panel, it's a bar coming loose under load. If your door has one spring across the top, or two, and one has a visible gap in the coil, that's the giveaway - the door won't lift, or it slams down instead of easing.
What you can safely do yourself: pull the release cord so the opener isn't fighting a dead spring, prop the door if it's part-open, and leave the rest alone. Extension springs on the side rails are a little more forgiving to look at but not to replace.
Either way, this is a two-person job with the right clamps, and the clamps aren't optional - they're what keeps the bar from becoming a problem. If you've got the tools and you've done it before, fine. If this is your first time looking at the coil, call it in.
Pricing
We don't have a set price to quote you here without seeing the door, the spring size, and whether it's a single or double - too many variables to put a number on sight unseen.
What we can tell you is what drives the number up or down: torsion vs extension, one spring or two, and whether the drums or cables need attention while we're in there anyway.
Mount Prospect's housing here runs newer than a lot of the territory we cover out of Evanston - median build year around 1969 rather than the 1959 median across the wider area - so springs here are more often standard commercial-length torsion units than the older, harder-to-source extension setups you find on pre-1960 stock.
That usually means parts are easier to match, which keeps the job simpler. It doesn't mean cheaper by default - a double door with two springs costs more than a single with one, regardless of the neighborhood. We'll give you the number on-site once we've looked at the door, not before.
The repair
We measure the spring by wire size, coil diameter, and length, matched to your door's weight and height - guess wrong and the door either won't hold or will slam.
On a 1969-era build, that usually means a torsion bar centered above the door with cable drums on either end, which is a cleaner layout to work on than the older side-mounted hardware some of the surrounding pre-1960 stock still carries.
We unload the old spring with winding bars, check the bearing plates and center bracket while the bar's off the door, and swap cables if they're frayed rather than wait for them to go next. New spring goes on, gets wound to the door's specific cycle count, and we run the door a dozen times watching balance before we call it done.
If the opener's been straining against a weak spring for months, we check the gears too - a burned-out opener motor is a separate conversation, but it's one we'll have with you if we see the wear.
Watch-outs
The complication we run into most in this area isn't the spring itself - it's what's been quietly wearing out around it. A door built in the late 1960s has had five decades to accumulate rust on the drums, hairline cracks in the end bearing plates, or a cable that's one bad winter from snapping.
We open the door expecting a spring swap and sometimes find the drums are pitted enough that they won't seat right on a new spring, which turns a one-part job into a two-part one on the spot.
Cold-weather metal fatigue plays a role too - this area sits in a cold-moderate climate band, and steel contracts and expands enough over a Chicago-area winter to loosen brackets that were fine in October.
The other place this goes wrong is mismatched springs from an earlier repair - someone put in a spring close enough to the right size that the door worked, but wound wrong, and it's been overloading the opener ever since. We'll flag that before we touch anything.
Local causes
Mount Prospect's 22,003 households sit on housing that's noticeably younger than much of the rest of the territory we serve out of Evanston - a median build year of 1969 against a wider-area median of 1959, and against stock across the broader service area that runs from 1938 up through the early 1990s. That gap matters for spring failure because it changes what's actually installed on the door. Newer builds here are more likely to carry standard torsion bar setups, which fail predictably as the coil fatigues from cycle count - open, close, open, close, for fifty-some years. Older extension-spring doors elsewhere in the service area fail differently, often from rust on the pulley rather than pure metal fatigue. With median household income here at $103,911, we also see more owners choose full spring-and-hardware replacement over a bare patch repair, since the cost difference is small next to the value of not doing this again in five years. We travel the 12 miles from Evanston for these calls - it's a planned visit, not a walk-up, so we ask what's going on with the door before we head out.
Questions
Most torsion springs are rated for a cycle count, not a calendar age, so a door used twice a day typically runs 7 to 12 years before the coil fatigues. On the 1969-era hardware common in this area, we mostly see failure from cycle wear rather than rust, which is the more common failure mode on the older extension-spring doors elsewhere in the wider service area.
You can, but we don't recommend it. Springs wear at close to the same rate when installed together, so replacing one leaves a mismatched pair - one older, weaker, and about to go. Most jobs we run replace both at once, even if only one has visibly failed, because the labor to come back for the second one costs more than doing it in one visit.
No. We work out of Evanston and drive the 12 miles out for calls in this area. That means we schedule the visit rather than showing up same-hour, so it helps to describe what the door's doing - won't lift, slams shut, one spring visibly gapped - when you call.
