What Causes It Around Here
Most of the houses we work on across the service area went up between 1957 and 2000, with a lot of that stock dating to the 1960s and 70s. Dexter runs newer than that average, the typical house here was built around 1985, which puts a good share of these doors on extension-spring setups from the 1980s and early 1990s rather than the older side-mount torsion hardware you see closer to the city. That matters for cable repair because 1980s extension-spring doors usually run two cables, one on each side, looping down to a pulley near the bottom bracket. When one goes, the door doesn't come down straight, it racks in the track, and the other cable takes a load it wasn't built to carry alone. Cold is the other piece. This is a severe cold-climate area, and cable strands that have been flexing over a pulley for three or four decades get brittle in a way that shows up as fraying, not sudden failure. You'll usually see it coming if you look.
How It Shows Up
On an extension-spring door, a going cable usually announces itself before it fully lets go: a door that closes crooked, sits an inch lower on one side, or drags against the track on the way down. Sometimes you'll hear a scrape or a light popping sound near the bottom corners as strands separate. A fully snapped cable is different, the door drops fast on one side, the section can bind hard against the track, and the opener will keep trying to pull it down or up on a door that isn't moving evenly. Don't run the opener again once you notice the lean. Forcing a partially failed cable through another cycle is what turns a $150-ish repair into a bent track and a damaged panel.
How Long You Are Without the Door
For most homes in this part of the service area, a cable job is a same-visit repair once the truck is on-site, cable, drums, and pulley hardware are common stock, not special-order parts. The door goes back to full working order in that one visit for a straightforward two-cable replacement. What extends the timeline is damage beyond the cable itself: if the door dropped hard enough to bend the bottom bracket or crack a stile on impact, that part has to be sourced separately, and we'll tell you that on-site rather than guess. We travel to Dexter from Ypsilanti, about 19 miles out, so we schedule the visit rather than treat it as a walk-up call, but once we're there, the cable work itself doesn't drag.
Getting It Booked In
Tell us it's a cable issue when you call and describe what you're seeing, a lean, a drag, a snapped strand hanging loose. That lets us bring the right drum and cable length for an extension-spring door rather than torsion hardware, which cuts down on a second trip. If the door is currently stuck half-open or half-closed with a person or car inside the garage, say that too; it changes how we prioritize the visit. Dexter households in this area report a median income around $130,068, well above the wider service area's $89,024, and higher-end openers and insulated doors are more common here than average, worth mentioning if your setup isn't a bare extension-spring door, since it changes what we load on the truck.
How We Fix It
We back out the spring tension safely, pull the damaged cable and drum, and check the pulley and bottom bracket for wear before running new cable, replacing one side but leaving a thirty-year-old cable on the other side just means a second call in a year, so we do both. We check that the track is still plumb and that the door is riding level once it's back under tension. On the roughly 2,592 households we account for in Dexter, extension-spring doors from the 1980s onward are common enough that we carry standard-length cable for this era of construction as routine stock, not a special order.
Can You Do This Yourself
A cable under spring tension is not a project to learn on. Extension springs store real force, and a cable that lets go while you're working near it can whip hard enough to cause a serious injury, this is the one repair on a garage door where we'd tell you flatly to make the call rather than watch a video first. If you're comfortable and just want to relieve pressure temporarily, clamping vice grips on the track below the bottom roller to keep the door from dropping further, that's reasonable as a stopgap until someone can get out to you. Beyond that, leave the spring and cable work to someone doing it with the door secured properly.

Questions, answered
Why does my Dexter house have extension springs instead of torsion springs?
It comes down to build year. Dexter's housing runs newer than a lot of the surrounding service area, median around 1985, and doors from that era commonly used two-cable extension-spring setups rather than the single centered torsion spring you see on older or newer builds. Which one you have changes the repair, not just the cable.
Is a same-day cable repair possible in Dexter?
We travel to Dexter from Ypsilanti, about 19 miles, so visits are scheduled rather than immediate walk-ups. Once the truck arrives, a standard two-cable replacement on an extension-spring door is usually finished in that one visit, since drums, pulleys, and cable in common lengths are stock parts we carry.
Can I just replace the one cable that broke?
You can, but we won't recommend it. Both cables on an extension-spring door see the same years of cold-weather flex, so if one has frayed enough to snap, the other is close behind. Replacing both in the same visit costs a little more up front and saves you a second call within a year or two.
