Experienced DIY single cables
If you've got the tools, the experience, and a second person to spot you, some people do handle single-cable jobs on lighter doors themselves.

Lomira, Fond du Lac
Lomira homes built mostly after 1980 run wider steel doors on two cables per side. We drive out from Fond du Lac to fix snapped or frayed cables on these newer sectional doors.
The repair
Lomira's median home dates to 1991, which puts most of the town's garage doors a full generation newer than what you'll find closer into Fond du Lac.
That means wider two-car steel sectional doors, usually 16 feet across, hung on two lift cables per side instead of the single cable common on older single-bay doors. When one of those cables frays or snaps, the door doesn't fall straight - it racks sideways in the tracks, because the opposite cable is still holding tension on its side.
First step is always killing power to the opener and clamping the torsion spring bar so nothing moves while we're under it. Then we pull the broken cable, check the drum it wound onto for grooove wear, and look at the roller and track alignment the door was dragged against while it hung crooked.
On a door this size, replacing one cable without checking its pair is a mistake - if one went from age and use, the other is close behind it. We replace both sides when the door's original hardware, match the drum size to the door weight, and reset cable tension evenly so the door doesn't lean when it closes.
Pricing
We don't publish a flat number here because cable jobs on a 16-foot two-car door cost more in parts and labor time than the single-cable repair on an older narrow door. What we can tell you: the job is priced by cable count, drum condition, and whether the track took damage while the door was off-balance. A straightforward two-cable swap on a door still square in its tracks is a faster job than one where the door has been run crooked for a few days and chewed up a roller or bent a track section. Ask for the number when we look at the actual door - quoting blind on cable work is how homeowners end up paying for a guess instead of the job in front of them.
DIY or pro
A snapped cable on a wide two-car door is not a spare-Saturday repair. The door itself is heavy enough that a torsion spring under tension can put you in the hospital if the winding bar slips, and a two-cable door means you're balancing tension on both sides at once so the door doesn't twist as you tighten.
If you've got the tools, the experience, and a second person to spot you, some people do handle single-cable jobs on lighter doors themselves.
On the double-cable setups common in Lomira, we'd rather you call than improvise - this is the one job on the list we tell people flat out not to DIY.
Local causes
Wisconsin's cold band runs hard through this part of the county, and cable failure here tracks temperature more than age most years. Steel cable loses flexibility below freezing, and a door that's cycled through a Lomira winter - cold garage, warm house side, repeated freeze-thaw on the cable's outer strands - wears at the fray points faster than the same door would in a mild climate. Add in that most of these doors are heavier two-car units carrying more static load per cable than a single-car door, and the strand at the drum takes more stress on every open and close. We see the same pattern on comparable-era stock in North Fond du Lac and Van Dyne, both close enough to share the same winters.
Booking
We come out from Fond du Lac, about 12 miles down to Lomira, and we don't keep a branch or a standing crew in town - the truck comes when you call. Tell us the door width and whether it's racked or just sitting loose on one side; that tells us what to load before we drive out. You can see the rest of what we cover for Lomira on our [area page](/lomira-garage-doors/), and if the job turns out to be something other than cable - spring, opener, panel - our [cable repair page for Fond du Lac itself](/garage-door-cable-repair-fond-du-lac-wi) covers the broader service area version of this same job.
Questions
Cable wear is gradual - the strands fray a little at a time, usually where the cable winds onto the drum. Cold weather speeds that up. By the time it snaps, the fraying had probably been building for weeks; the door just gave no obvious sign until the last strand went.
You can, but on a two-car door we usually recommend replacing both cables at once. They're the same age and under the same load, so if one failed from wear, the other is close behind it. Doing both now saves a second service call later.
No. The spring lifts the door's weight; the cable guides it up and down the track. A broken spring makes the door impossible to lift by hand. A broken cable usually lets the door drop or hang crooked in the tracks. Different parts, different fix.
