A garage door should be a low, steady hum. When it starts making new noises, it’s telling you a part is wearing out. Here are the five most common sounds and what each one usually means.
1. Grinding
Grinding is usually worn rollers or a dry opener gear. Cheap plastic rollers wear flat over time; replacing them with sealed nylon rollers is one of the most satisfying, quietest upgrades you can make.
2. Popping or banging
A single loud bang is almost always a spring breaking. Repeated popping as the door moves can mean the sections are binding or the door is out of balance. Worth a look before something gives.
3. Squealing
Squealing is the easy one: dry hinges, rollers, and springs. A proper lubrication during a tune-up usually silences it. Avoid WD-40, which is a cleaner, not a lubricant.
4. Rumbling
A deep rumble often points to loose hardware or a door that’s drifting out of balance, forcing the opener to work harder than it should.
