Why Is My Garage Door Making a Loud Grinding Noise?

A garage door that used to run quietly and now grinds, squeals, or bangs during operation is telling you something specific is wearing out. The type of sound and where it happens in the door's cycle are the two biggest clues to what's actually going on.

What the Sound Usually Tells You

Different noises point to different components:

• A metallic grinding sound throughout the whole cycle — usually dry or worn rollers that need lubrication or replacement
• A loud bang followed by the door refusing to move — almost always a broken spring
• A grinding or straining sound from the opener unit itself, with the door moving slowly or not at all — often a worn drive gear inside the opener
• Squealing concentrated at the top or bottom of the cycle — frequently a hinge or track section that needs lubrication
• A rattling or banging sound during travel — loose hardware, such as bolts on the track brackets, that has worked itself loose over time

What We Check First

We start by watching and listening to a full cycle to pinpoint exactly where in the door's travel the noise occurs, then inspect rollers, hinges, cables, and the spring assembly for visible wear. A quick lubrication and hardware tightening resolves a surprising number of noise complaints, but if a spring shows wear or a roller has worn through its bearing, those need to be replaced rather than serviced — running a worn spring or roller longer usually leads to a more sudden, less convenient failure.
