What causes a garage door to come off track?
Most doors come off track because of debris in the track, a frayed or slipped cable, a broken spring that lets the door drop, a bent track from a bump, or worn rollers and loose brackets. In Buckingham, gravel, mud and leaves tracked in from long driveways are a frequent cause.
A garage door that has come off its track is one of the more alarming things to find in your garage. The door may be tilted, jammed halfway, or hanging with one corner low. Here is what usually causes it in Buckingham, what to do right away, and what the fix costs.
First, stop using it
Do not press the opener button again. An opener will keep pushing or pulling, and that can bend the track, crack panels and pull rollers loose. If the door is closed, unplug the opener. If it is up or dangling, clear the garage of kids, pets and anyone else. Do not try to push it back into place by hand. The door is heavy and the springs are still under tension.
Cause one: something in the track
This is the most common reason we see in the township. Long driveways and country roads carry gravel, mud and leaves into the garage. A small stone in the bottom of the track is enough to lift a roller out as the door comes down. Once one roller is out, the others on that side follow.
Cause two: a cable problem
Each side of the door hangs from a steel cable that winds onto a drum at the top. If one cable frays and snaps, or slips off its drum, that side of the door loses its support and drops. The door tilts, and the rollers on the low side pop out of the track.
Cause three: a broken spring
When a spring breaks, the door can drop suddenly. That jolt can throw a cable off its drum and knock the door out of line. On heavy two-spring doors, which are common on newer Buckingham homes, the force is considerable.
Cause four: a bump
A car, a mower or a trailer that clips the bottom of the door or the side of the track can bend it. A bent track pinches the rollers and pushes them out.
Cause five: worn rollers and loose brackets
Rollers with split wheels or tired bearings start to wobble and can work their way free. Track brackets that have worked loose let the track shift away from the door. Both get worse slowly, then fail at once.
How it gets fixed
Once the door is clamped and the springs are made safe, it is guided back into the rails. Frayed cables are replaced on both sides. Kinked rail gets trued up or swapped out, tired rollers are changed, and the door is balanced and cycled a few times.
What it costs
This site's price table lists $135 to $240 to set a door back in its rails. A cable or drum repair runs $150 to $325. Replacing a bent track section runs $230 to $340. You get the price before work starts.
How to prevent it
Sweep out the bottom of the tracks, especially in fall when leaves blow in. Watch for frayed cables. Listen for grinding rollers. If you notice the door running unevenly, call (267) 839-8884 before it comes off.
