The Symptom
The call we get most from Florence isn't a dead opener - it's a bang from the garage followed by a door that won't budge, or one side dropping while the other holds.
Snapped extension springs
That's a snapped extension spring, the kind mounted along the horizontal track rather than overhead on a torsion bar. We also see cables jumping their drum and rollers that have gone from rolling to grinding.
Florence housing age pattern
There's a reason this pattern shows up here more than it does closer to Georgetown. The median home in Florence went up around 1975, well before the service area's overall median build year of 1993.
Single-panel steel construction
A door from that era is more likely to be a single steel panel on an old-style extension spring setup than the insulated, torsion-driven doors going into newer construction. The hardware is different, the failure points are different, and the fix is different too.
How Long It Takes
We run this out of Georgetown, 13 miles from Florence, so there's no branch or depot sitting closer. That drive is built into how we schedule the day rather than something we quote you a number on - we don't promise a response window for Florence calls, because honesty about the distance matters more than a round figure that might not hold.
Once a truck is on site, most spring and cable jobs on this kind of door are same-visit work. Where it slows down is parts: if the door needs a part sized to match older, non-standard hardware, that sometimes means a second trip rather than a one-stop fix. We'd rather tell you that up front than have you wait on us.
The DIY Question
An extension spring under tension is not a safe thing to free-hand, even if you've watched a video on it.
Corroded second spring
The spring that's already broken is less dangerous than the one that's about to - that's usually the second spring on the other side of a double-spring door, holding on by corrosion alone after decades of the same mild-with-some-freeze cycling this area gets. What you can reasonably check yourself: whether the track is visibly bent, whether the rollers are plastic and cracked versus metal and worn, and whether the door is binding on one side only.
Non-standard spring parts
That tells us something useful before we even get a truck moving the 13 miles out. Replacing the spring itself, though, isn't a weekend project on a door this old - the parts and the tension aren't standardized the way they are on newer torsion systems.
What Can Go Wrong
On a door built around 1975, the list of likely failures looks different from a 1990s or 2000s door. Extension springs stretch and lose temper over the years instead of snapping cleanly, which means a door that's slow and uneven long before it fails outright. Track brackets on older installs were often fastened straight to wood framing that's shifted with the house, so the track itself can be out of plumb even when every part on it is fine.
The area's mild climate with occasional freeze doesn't crack a slab the way a harder winter would, but it does stiffen old grease in rollers and hinges every time the temperature drops, and that stiffness is often what turns a quiet door into a noisy one. Non-insulated steel panels from this era also warp slightly with heat over enough summers, which throws off how evenly the door sits in the track.
What You Pay
We don't have a published price list to hand you here, and we're not going to invent one - the parts cost for a door built in 1975 depends on what's actually on it, and that varies more than it does on newer, standardized doors.
Track straightening versus replacement
What we can tell you is what drives the number: whether the spring size is still a common stock item or something we have to match, whether the track needs straightening or full replacement, and whether one trip covers it or two.
Repair-first conversations
Florence's median household income, at $72,743, runs below the service area's overall figure of $99,368, and that's worth saying because it often shapes the conversation toward repair-first rather than jumping straight to full door replacement. We'll tell you when a repair isn't worth it compared to swapping the door, but we won't push a replacement just because the door is old.
How We Fix It
For a snapped or failing extension spring, we match the wire gauge and length to what's already on the door rather than swapping in a torsion conversion unless you ask for one - on a house this age, changing the whole system is a bigger job than most calls need. Cables get replaced in pairs, not one at a time, since the one that hasn't broken yet has usually seen the same wear.
If the track is bent rather than just dirty, we straighten or replace the damaged section and check the brackets against the framing before calling it done. We test the door's balance by hand before we leave, since a door that opens fine under a motor but is out of balance will just wear the next spring early. Every visit starts with the 13-mile drive from Georgetown, so we try to diagnose as much as we can from what you describe on the call.
