Garage Door Cable Repair in Westwood, MA
If your garage door is hanging at an angle, won’t sit flat on the slab, or one side has dropped lower than the other with a loud bang and a loose steel wire pooled near the bottom bracket, a cable has let go. It’s a common call in neighborhoods like Westwood where a lot of garages sit on sloped driveways and the door takes an uneven load every time it opens.
A dropped cable is not the same problem as a dead opener or a blocked sensor. It’s a mechanical failure in the system that holds the door’s weight, and it needs a trained eye before anyone touches that door again.
This page covers what we actually find when a Westwood cable fails, what the repair involves, and what it costs. No DIY steps here, because the cable and the spring system behind it are under enough tension to cause serious injury if handled without the right tools.
Garage Door Cable Repair in Westwood
The cables on a residential garage door run from the bottom brackets up to the drums mounted on the torsion spring shaft, or in older extension-spring setups, back along the horizontal track to a pulley near the rear roller bracket. Either way, the cable’s job is to transfer the spring’s lifting force to the bottom of the door. When it frays, jumps off the drum, or snaps outright, that corner of the door loses support and drops.
Most of the Westwood calls we get are one of three things: a frayed cable that’s been rubbing on a misaligned drum and finally gave out, a cable that’s slipped off the drum because the door was run while out of balance, or a snapped cable on a door where the torsion spring itself is also near the end of its cycle life and took the cable with it when it failed. The repair means releasing tension safely, pulling the old cable and drum assembly, fitting correctly sized replacement cable rated for the door’s weight, and re-tensioning the spring system so the door balances evenly before we ever reconnect the opener.
We don’t patch a frayed cable with electrical tape or re-string it onto a worn drum. If the drum grooves are chewed up or the cable is the wrong gauge for the door, that gets replaced too, or the repair fails again inside a few months.
What we look at
What we look at
Every cable repair call starts with checking the whole lift system, not just the broken wire. A cable rarely fails in isolation.
Door balance and movement
We disconnect the opener and move the door by hand to see where it holds position and where it wants to fall or fly up. A door that’s badly out of balance is what overloads a cable in the first place, and it’s also what burns out an opener motor over time.
Spring type and cycle rating
Torsion springs mounted above the door and extension springs running along the tracks behave differently and carry different cycle ratings. We check which type is installed, roughly how many open-close cycles it’s rated for, and whether it’s close to the end of that life, since a tired spring is often the real reason a cable gave out.
Cable and drum condition
We check both cables end to end, not just the one that broke, along with the drums they wrap around. Fraying, rust, and a drum groove that’s worn smooth all tell us whether a single cable swap will hold or whether both sides need attention.
Track alignment, opener settings, and safety reversal
A bent track or a loose bracket can pull a cable off its drum even when the cable itself is fine. We also check the opener’s force and limit settings and run the safety reversal test, pressing a piece of wood on the ground under the closing door to confirm it stops and reverses. A door that was out of balance long enough to snap a cable has often been fighting the opener’s auto-reverse too.
Homes in Westwood
Westwood’s housing stock shapes what we see on these calls more than people expect.
Homes in Westwood
A good share of Westwood’s housing is Colonial and split-level construction from the 1950s through the 1980s, much of it on larger lots with attached two-car garages. Double doors in the 16-foot width are common on these, and a door that size puts more load on its cables and springs than a single 8 or 9-foot door, so wear shows up sooner when the system isn’t dialed in correctly.
There are also older sections of town, closer to University Avenue and around the center, with smaller single-car attached and detached garages built for one vehicle. Some of these still run original wood doors or early steel replacements, and on those we sometimes find older extension-spring setups rather than torsion systems, which changes how the cable routes and how we approach the repair.
What it costs
Cost depends on what actually failed, not just the one cable you can see.
What it costs
A straightforward single-cable replacement on a door that’s otherwise in good shape, with healthy springs and drums, generally runs between {PRICE_LOW} and {PRICE_HIGH}. That range moves based on whether both cables need replacing, whether the drums or springs are also worn and need swapping at the same time, the width of the door, and whether the track needs adjusting to stop the problem recurring. We give you the actual number after we’ve looked at the door, not before.
How fast we can get there
Westwood is about 11.7 miles from our Bellingham location, a quick run down through Route 109 or Route 1 depending on traffic.

Common questions
My Westwood garage door dropped on one side with a bang. What happened?
That's almost always a snapped or derailed cable on that side. The bottom bracket loses its support and the door corner falls until it rests on the track or the ground. Stop using the door and the opener until a cable can be inspected and replaced.
Can I just replace the cable myself?
No. The cable works against the torsion or extension spring system, which stores a large amount of force. Releasing or re-tensioning that system without the right bars and clamps has caused serious injuries. This is a repair for someone trained to do it.
Is it the cable or the spring that actually failed?
Often both are involved. A spring nearing the end of its cycle life changes how evenly the door moves, which puts extra strain on the cables and drums. We check the whole system, not just the broken part, so we're not back out again in a month.
Why did only one cable break if both are the same age?
Uneven wear is common. A slightly misaligned track, a worn drum groove on one side, or a door that was slightly out of square can concentrate stress on one cable while the other looks fine. We check both regardless of which one failed.
Do you work on older wood garage doors in Westwood?
Yes. Some homes in Westwood still have original wood doors or early steel replacements running older extension-spring hardware. The repair approach is similar but the cable routing and hardware differ from a modern torsion setup, and we carry parts for both.
