Garage Door Making Noise: What Each Sound Means
Grinding usually means a dry or failing roller bearing. Squealing means dry hinges or rollers. A bang on opening usually means a spring or cable letting go. Popping is section hinges binding. Rattling is loose hardware. Most noise is resolved by an annual tune-up at $95 to $180, and most of it gets expensive if ignored.
Match the sound to the cause
Grinding. Metal on metal without lubrication. Most often a roller bearing that has run dry and is sliding rather than rolling. Sometimes a worn end bearing plate on the torsion shaft. Both are cheap now and expensive later.
Squealing or screeching. Dry hinges and rollers. This is the noise that responds best to lubrication, and it is the most common reason people book a tune-up.
A single loud bang. A spring or a cable letting go. If the door then will not open, it is the spring. Stop using the opener.
Popping or snapping on the way up. Section hinges binding as the door articulates around the curve. Usually dry hinges, sometimes cracked ones, occasionally a door that is out of square.
Rattling. Loose hardware. A garage door vibrates every single time it runs and bolts work themselves loose over years. Tightening them takes twenty minutes and prevents a surprising amount.
A rumble you feel in the house. Chain drive noise transmitted into the structure. This is not a fault, it is what chain drives do, and the fix is either isolating the mounting or fitting a belt drive.
Straining or humming with no movement. The motor is powered but something between it and the door has failed: a stripped gear kit, a broken trolley, or a door so out of balance the opener cannot lift it.
The five minute check
With the door closed, pull the manual release and move it by hand.
If it is quiet by hand and loud with the opener, the noise is the opener.
If it is loud by hand, walk the door slowly and listen. You can usually put a finger on the exact roller or hinge making the sound.
What to lubricate, and what not to
Use a garage door silicone or white lithium spray.
Do lubricate: hinge pivot points, roller bearings, the torsion spring itself, the end bearing plates, the opener rail if it is a chain or screw drive.
Do not lubricate: the track. Track needs to be clean and dry. Grease in the track collects grit and turns into an abrasive paste that wears rollers faster than no lubricant at all.
Do this twice a year, in spring and autumn, and it will silence most of the noise a garage door makes.
When to call somebody
Call when the noise is grinding rather than squealing, when there is a new noise at one specific point in the travel, when the door has started running unevenly, or when lubrication has stopped helping.
A tune-up at $95 to $180 covers the inspection, the lubrication, the hardware tightening and the adjustments. Parts found and replaced are quoted separately and should be shown to you.
Related questions
Is a noisy garage door dangerous?
Not immediately, but it is a warning. Almost every expensive garage door failure has a noisy phase before it. A grinding roller that seizes takes the door off the track; a rattling bolt that falls out drops a hinge.
Which lubricant should I use?
A garage door specific silicone or lithium spray on hinges, rollers, springs and bearings. Not WD-40, which is a solvent and displaces the lubricant that is already there. Never lubricate the track: it should be clean and dry.
Will a new opener make my door quieter?
Only if the noise is coming from the opener. A belt drive is dramatically quieter than a chain, but if the noise is the door hardware, a new opener changes nothing.
