Doors talk. Not in a useful, sentence-forming way — more in a "this is the noise it makes when it's dying" way. Most of my service calls start with the customer trying to describe a noise on the phone. After 1,240 of these, I have a translation dictionary.

This post is that dictionary.

For each noise: what it sounds like, what it actually is, and how urgent the repair is on a scale of "next Saturday" to "stop using the door now."

The grinding noise

Sounds like: A coffee grinder. A continuous low scraping, throughout the door cycle. Often louder on one side than the other.

What it is: Worn rollers. Specifically, the cheap nylon stem rollers that came with most builder-grade Richmond doors built from 1995–2015. They wear flat on one side, lose their bearing, and start dragging in the track instead of rolling.

Urgency: Low. You can run the door this way for months. But the grinding is wearing out the track and overloading the opener. Replace them at your next maintenance visit.

Cost to fix: $285–$425 for a full set of 10 (single door) or 14 (double door), nylon-with-steel-bearing upgrade. The whole job takes me 30 minutes.

The popping or pinging noise

Sounds like: A single sharp metallic "ping" or "pop" during the open or close cycle. Sometimes more than one per cycle. Sometimes only on cold mornings.

What it is: This is the one that makes me drop other things and call back fast. A ping during cycling is the spring telling you it's about to fail. The sound is a single coil under stress, slipping or cracking microscopically as the spring works.

Urgency: High. Treat as a spring-failure warning. If you hear pinging, do the two-second test from post 1 today. If the spring is still intact, you have somewhere between 3 days and 3 weeks. If it's already showing a gap, you have hours to days.

Cost to fix: $385–$625 for a pair, scheduled. $425–$675 same-day. $625–$895 if it fails first and the door is stuck.

The bang

Sounds like: A gunshot or a backfire. One enormous, room-shaking concussion. Usually followed by silence. Sometimes the door drops or tilts to one side immediately.

What it is: A spring or a cable just failed catastrophically. The bang is the sound of stored elastic energy releasing all at once.

Urgency: Stop using the door. If the door is closed, leave it closed. If it's open, don't stand under it. Call somebody.

Cost to fix: $385–$625 for spring pair, $215–$345 for cable pair. If both are damaged: $545–$895 combined.

The squeal

Sounds like: A high-pitched, dry, sustained note. Often comes from the hinges or the rollers. Worse in cold weather. Worse if you used WD-40 to "fix" the problem at some point.

What it is: Lubrication failure. The hinges and rollers need fresh garage-door-rated oil. WD-40 is not lubricant; it's a solvent. If you've been spraying WD-40 on your hinges, you've been stripping the lubrication for months and the metal is now rubbing on metal.

Urgency: Medium. The squeal isn't dangerous, but the underlying wear is real. Hinges that run dry for a year start cracking at the pivot. Replace cracked hinges before they fail completely.

Cost to fix: $185–$285 for a full hinge-lube and adjustment service call. Cheap. The kind of work that should be done annually.

The chatter

Sounds like: A rapid metallic chattering, like a sewing machine. Comes from the opener head. Worse when the door first starts moving from a stop.

What it is: Chain or belt drive sprocket slipping. On a chain drive: the chain has stretched and is jumping teeth. On a belt drive: the belt is glazed and slipping. Both are caused by age + tension drift.

Urgency: Medium. The opener still works for now. Left alone, the chain will jump out of the sprocket eventually and the door will stop opening.

Cost to fix: Chain tension adjustment: $145–$225. New chain: $245–$385. New belt: $325–$485. If the opener is over 10 years old, this is usually the prompt to replace the whole opener rather than throw new parts at it.

The thud

Sounds like: A heavy "whump" when the door reaches the bottom or the top of its travel. Like the door is dropping the last 10 cm instead of being lowered.

What it is: Travel limit setting on the opener is wrong, OR the springs are weak and the door is over-running the opener's slow-stop logic at the end of cycle.

Urgency: Low to medium. The opener is fine, but the door slamming at the end of cycle is hammering the bottom seal, the floor, and the opener's gear train.

Cost to fix: $95–$165 service call for travel limit adjustment. If it's spring weakness, see post 2 for what that costs.

The clunk

Sounds like: A sharp single "clunk" at the same point in the cycle every time. Usually around the curve where the door transitions from vertical to horizontal track.

What it is: Most commonly: a worn-out hinge that has lost its pivot tolerance, or a roller that's catching on a misaligned track joint. Less commonly: a panel that's coming loose from its frame.

Urgency: Medium. If a hinge is cracking, it will fail eventually and the panels will misalign.

Cost to fix: $145–$245 for a single hinge replacement. $215–$385 for a roller-and-hinge inspection-and-fix service call.

The whine

Sounds like: A continuous medium-pitch electric whine from the opener head. Different from the squeal; this one is electrical, not mechanical.

What it is: Old AC motor opener with worn brushes, or a DC motor opener with a failing logic board capacitor. Either way, the opener is on its way out.

Urgency: Low. You'll get warning. The whine usually predates the actual failure by 3–8 months.

Cost to fix: Brushes are sometimes replaceable on older AC openers ($185–$285). Logic board capacitors on DC openers can be replaced ($245–$425) but rarely worth it if the opener is over 8 years old — replace the unit. New opener installed: $725–$1,295 depending on spec.

The screech

Sounds like: A short sharp metal-on-metal screech, intermittent during cycling. Worst on the first cycle of the day.

What it is: Almost always the torsion bar bearings drying out. The torsion tube rides in plastic-bushing brackets on each end. Those bushings dry out and the steel torsion bar starts rubbing on plastic-on-steel.

Urgency: Low to medium. Bushings will eventually crack, the bar will sag, the door will go out of balance.

Cost to fix: $145–$245 for new end bearings with lube. Easy job, takes 25 minutes.

The hum

Sounds like: Continuous low hum from the opener, but the door doesn't move (or moves very slowly).

What it is: The opener is straining. Either the door is out of balance (the opener is fighting gravity), the rollers are dragging, OR there's a mechanical bind somewhere.

Urgency: Stop running the opener until you find the cause. Forcing it through a bind burns out the motor — and replacing a motor that was destroyed by being forced to push past a stuck door is the most preventable opener failure I see.

Cost to fix: $95–$165 service call to diagnose. The fix depends entirely on what's binding.

The mystery rattle

Sounds like: Vague rattling. Hard to localize. Comes and goes.

What it is: Loose hardware. Lag bolts that hold the track to the wall, lag bolts that hold the opener bracket to the framing, screws that hold the bottom-bracket assembly, etc.

Urgency: Low. Mostly cosmetic and slightly annoying. Tighten and forget.

Cost to fix: Free if you do it yourself with a socket wrench. $95–$165 if I do it as a tune-up.

A Seafair story

A guy on Williams Road in Seafair called me last August. Said his door "sounded weird, kind of like a coffee maker that's almost empty." I drove out the next morning. Within 30 seconds of watching the door cycle once I knew it was rollers — that exact dry-grinding pattern.

Full set replaced for $385 with the nylon-and-steel-bearing upgrade. Cycle time on his door went from 14 seconds to 10 seconds (less drag on the opener). Noise level dropped about 8 dB. He said his wife told him she'd been listening to the grinding for a year and hadn't said anything because she didn't want to be "the one who's always complaining about the house."

Sometimes I think my actual job is marriage counselling with a torque wrench.

That's the post.
