Garage door noises and what each one means
A garage door that starts making a new noise is usually pointing at one worn part. Some of these sounds are routine maintenance, and two of them mean stop opening the door until it has been looked at.
Most garage doors make some noise. What matters is which noise, where in the cycle it happens, and whether it is new. A sound that appeared this week on a door that used to run quietly is usually one worn part, not the whole door.
Grinding
Metal working against metal, from one of two places. Rollers whose bearings have collapsed drag along the track instead of turning, and the noise follows the door up and down. The other source is inside the opener, where a worn drive gear grinds while the door barely moves. If the motor runs and the door stays put, that is the pattern set out on opener runs but the door does not move, and replacement options are on garage door openers.
Squealing
A high, continuous sound through the travel, usually dry rollers, hinges or end bearing plates. It is the least alarming noise here, and often comes back to lubrication and adjustment on a service visit. It still deserves attention, because a squeal that turns into a grind means a bearing has gone from dry to failed.
Scraping
Something is touching that should not be: a roller riding the lip of the track, a bent track section, or a panel catching the frame as it passes. Scraping is a stop signal. Running the door anyway widens the damage and can pull a roller out completely. Read off track or cable, then cable and track repair for what the fix involves.
Rattling
Loose hardware. Hinge screws, track bolts and the top fixture work loose over thousands of cycles, and chain slap on the opener rail adds to it. Rattling across the whole door, on an older single-skin panel, is usually several small worn parts at once. That is the point where a new door starts to make more sense than another round of parts, and you can put one on a photo of your own frontage first with the visualizer.
A bang on closing
One loud bang has two causes worth separating. If the door drops the last foot and lands hard, spring tension is no longer balancing the weight. If you hear a single sharp bang from a closed garage with nobody touching the door, a torsion spring has almost certainly broken. Both are covered on broken spring, with the repair itself under spring repair.
Stop using the door if
- There was a bang, and now the door feels heavy or will not stay where you leave it
- The door scrapes and sits crooked in the opening
- A cable is slack, frayed or unwound off its drum
- Grinding stops the door part way, which often overlaps with a door that will not close
Do not touch a broken spring, and do not try to re-seat a door that has come off its track. Both hold or release a great deal of energy, and a door in that state can fall. Leave it closed, keep people and cars out from under it, and have it looked at.
Having the noise identified
Diagnosis is a short job on site. Our technician runs the door, watches the travel and checks the balance, the hardware and the opener. The inspection and estimate are free whether or not you go ahead, and the worn part we replace is written on the invoice with its specification.
Book a free estimate, wherever you are in Los Angeles County. The other symptoms are on garage door problems, and what a visit covers is under garage door repair.
Get the door looked at.
The price is written down before anything is touched, and it holds. Nothing else is done without your say-so.
