Garage Door Cable & Drum Repair
One corner sitting lower, or a cable hanging off its drum, means the lift system is out of balance. It wants looking at before the next cycle, not after.

You don't need to know which part broke — that's the technician's job. But knowing roughly what each repair involves makes it much harder for anyone to sell you something you don't need.

Cables and drums
One corner sitting lower, or a cable hanging off its drum, means the lift system is out of balance. It wants looking at before the next cycle, not after.

New openers
Door weight, headroom, travel, and the safety devices decide this — not the horsepower number on the box.

Openers
Motors take the blame for dead springs constantly. Worth knowing which one you've got before you buy an opener you didn't need.

Panels and sections
Some damaged sections come back perfectly well. Some quietly wreck how the whole door hangs. You should know which one you've got before you pay for either.

General repair
Tell us what the door is doing and we'll get it in front of someone who can fix it — with the price agreed before the work starts.
See what's included
Replacement doors
Replacement pays a lot better than repair, so the reasoning matters. We separate what is genuinely beyond fixing from what somebody would simply prefer to sell you.

Sensors and safety
Blinking eyes, a door that only closes while you hold the button, a failed obstruction test. We'll get it traced properly — never taped over, jumpered, or bypassed.

Springs and balance
If your door suddenly weighs a couple hundred pounds, a spring has almost certainly let go. Leave it down, keep everyone clear, and let someone with the right winding bars deal with it.

Tracks, rollers, hardware
Grinding in the same spot, a door that shakes the whole wall, a roller creeping out of its track — all cheap to sort now, all expensive once the door comes off.

Maintenance
A proper tune-up finds shifting balance, worn rollers, and loose hardware — the things that let go on a cold morning when you're already late.

Seals and insulation
Daylight under a shut door, a bottom seal gone hard, rain running across the garage floor. Usually a small job — and much smaller than what it costs to ignore.

Off-track and stuck
Every extra cycle bends another panel and drags more cable out of line. Leave it where it is, keep the opening clear, and get it stabilized properly.
See what's includedWorth knowing
It's the noisy part with the motor in it, so it takes the blame. But a motor that strains and quits is usually lifting a door whose spring has failed — the opener was never designed to carry that weight on its own. Replace the opener and you'll have a new opener with the same problem.
The same goes the other way. A door that refuses to close is very often a pair of safety sensors knocked out of alignment by a bike, which is a five-minute fix, not a new door.
Every page here says which parts are connected and where the safety line sits, so you can ask a better question when someone's standing in your driveway with a quote.
