Garage Door Cable and Off-Track Repair in McDonough

A door hanging crooked in its opening, with a cable loose on one side or rollers out of the track, looks like the end of the door. It usually is not, provided nobody runs the opener again.

What happened

A cable snapped or came off its drum

The lift cables carry the door's weight from the bottom corners up to the drums on the spring bar. When one frays through, often at the bottom bracket where it is hardest to see, that side of the door loses support and drops. Cables also jump off their drums when a door is closed onto something, or when a spring breaks and the tension changes suddenly.

Rollers out of the track

With one side dropped, the door twists in the opening and the rollers on that side can leave the track. A car clipping the track, or a door closed on a bin, can do the same thing without any cable failing.

A bent track

Vertical tracks are bolted to the wall either side of the opening and are easy to knock out of line with a bumper or a mower. A track that is bent or has pulled away from its brackets lets rollers bind and eventually escape.

What to leave alone

Unplug the opener so nobody runs it, because an opener pulling on a door that is off its track bends sections and tracks and turns a cable repair into a door replacement. Do not loosen the bottom brackets or try to put a cable back on its drum; both are under spring tension. Do not try to force the door up or down by hand. If the door is stuck open, leave it open and keep people from walking under it.

What the repair involves

The door is secured, the spring tension released, the cables replaced as a pair (the other one is the same age and has taken the same load), and the rollers re-seated. Any bent track is straightened or replaced and re-fastened, and the door is re-tensioned and balanced.

The thing to ask about is what caused it. A frayed cable on a ten-year-old door is wear. A cable that jumped its drum on a newer door usually means the spring tension or the door balance is off, and replacing the cable without fixing that means it will happen again.

An off-track door is usually a single-visit repair if it is caught before the opener does more damage. Call with what you can see, and a photo of each side of the door helps the company bring the right parts.

Older doors and the bottom of the opening

On older doors, cables tend to fail where they meet the bottom bracket, because that is where rainwater and road grime collect and where the bottom seal holds moisture against the steel. A rusted bottom bracket or a soft bottom section is worth pointing out on the visit. Sometimes it is a part; sometimes it is the first sign that the door is near the end of its life.

What it costs

Local companies generally quote cable replacement and putting a door back on its track at $150 to $350, more if a section is bent, a drum is cracked, a track needs replacing or a spring broke at the same time. Get the parts listed on the quote, so you can see whether the cables are being replaced as a pair.

Common questions

Can I put the door back on the track myself?

It is not recommended. The door is under spring tension through the cables, and a door that is off its track can shift or drop as you work on it. It is the kind of job where a small mistake becomes a bent door or an injury.

Why did my cable snap?

Most often age and rust at the bottom bracket. A cable that jumped its drum rather than snapping usually points to slack in the system, from a weak spring, a door closing onto an obstruction, or tension set wrong after an earlier repair.

Will the door need replacing?

Usually not. If a section has bent badly or the door has fallen, it may need a section or more. Unplugging the opener straight away is the best way to keep it a cable job.
