Spring Repair for Irmo's 1980s Garage Doors

What the Repair Takes

Most of the doors we open up in Irmo are steel sectional units, hung in the mid-1980s when the neighborhood was built out. The median year built here is 1984, which puts a lot of these doors right at 40 years on the same torsion spring they left the factory with. These are standard 16x7 double doors or 8-9 foot singles, nothing custom, which is good news for parts availability. The repair itself is a swap: wind down the old spring, measure the wire gauge and wind count against the door weight, set the new spring on the same torsion bar, and re-tension it. On a double door with two springs, we replace both even if only one broke, because the other is carrying the same 40 years of cycles and it's one more trip you don't want to pay for twice. We check the cable drums and the bottom brackets while the tension is off the door, since that's the only time it's safe to look at them closely. If the bottom bracket is bent or the cable is frayed, that gets flagged before we close the door back up. We don't rebuild a door that's rusted through at the bottom panel - that's a replacement conversation, not a spring one.

The Cost of This Job

Irmo's median household income sits at $85,137, well above the $64,003 median across the wider service area we cover from Lexington. We don't price jobs differently by zip code, but it does mean we see more requests here for the heavier-duty spring option or a matching second spring on both sides of an aging door, rather than the cheapest single-spring patch. A straightforward single-spring swap on a standard door is the bulk of what we quote out here. Double springs, a stripped or rusted shaft, or drums that need replacing alongside the spring push the job up from there. We quote on-site once we've seen the door and the spring size, because wire gauge and door weight both move the number and we're not going to guess over the phone and then surprise you in the driveway.

Why It Happens Here

A torsion spring is rated for a cycle count, not a calendar date, but in a neighborhood built mostly in the 1984 era, calendar and cycle count end up close together. A spring installed when the house went up has had roughly four decades of two-trips-a-day use, and galvanized torsion springs from that build period weren't coated the way current stock is. South Carolina's mild climate with occasional freeze swings isn't the main driver of failure here the way it would be in a harder winter state - it's straight metal fatigue from cycle count on original hardware. We see more of these original-spring failures in Irmo than in newer sections of the service area simply because of when the housing stock went up.

Time on the Job

A single-spring replacement on a standard door runs under an hour once we're on-site with the right size spring. Add a second spring, a drum swap, or a bent bracket and you're looking at closer to ninety minutes. We travel to Irmo from Lexington, about 8 miles out, so the only variable we can't promise you ahead of time is traffic on the drive - the work itself is predictable once we're in your driveway with the door open.

What You Are Seeing

A broken torsion spring usually announces itself the same way: the door won't budge, or it slams down fast instead of lowering under control, or the opener strains and clicks without lifting the door at all. Look at the spring itself, above the door on the horizontal bar - a clean break shows as a gap in the coil, sometimes with the two ends sprung apart a few inches. If the door is still moving but sounds like metal grinding on metal, or the opener is working harder than it used to, that's often a spring losing tension before it snaps outright, and it's worth a look before it fails on you at the worst time - like with the car halfway in the driveway under it.

Stocked Parts

We carry the common torsion spring sizes that match standard doors from the 1984 era on the truck - the wire gauges and wind counts that cover most single and double garage doors built across this part of the service area. What we don't stock are oddball sizes for custom or oversized doors, or springs for older extension-spring setups that some of the earliest houses in the wider area still have. If your door needs one of those, we'll order it, and that adds a day or two rather than same-visit service. We'd rather tell you that upfront than quote a same-day fix we can't deliver.
