A loud garage door under a bedroom is almost always worn rollers, loose hardware, or an old chain-drive opener. In San Francisco tuck-under garages, we fix the noise from $90 in one visit most of the time.
Most Sunset and Richmond District houses were built with the garage right under the front bedroom, so every clunk travels straight up through the joists. I get calls from people losing sleep over a door that used to be quiet. It's usually a one-visit fix, and it's rarely as expensive as folks expect.
The wood framing acts like a drum. When the garage sits under the bedroom, vibration from the door, the springs, or the opener gets picked up by the joists and carried into the room above. A door that would sound mildly annoying in a detached garage feels like a small earthquake under your headboard.
The Doelger-era rowhouses in the Sunset and the Edwardians in the Richmond District (San Francisco's, not the city across the bay) were framed to fit a car under a house on a narrow lot. Nobody was thinking about sound. So small mechanical problems get amplified in a way they wouldn't be elsewhere.
The flip side is that small fixes make a big audible difference. You don't always need a new door or a new opener. Sometimes tightening the right bracket or swapping a set of rollers cuts the noise by more than half.
A little motor hum and a soft click as the rollers pass through the track is normal. Banging when the door starts or stops, grinding as it travels, or a rattle you can feel through the bedroom floor is not.
If your door has gotten louder over the past few months, something changed mechanically. Rollers wear flat, hinges loosen, springs lose tension. None of that happens overnight, which is why the noise creeps up until one day it's keeping you awake.
My advice on these calls is the same every time. If the noise is new or getting worse, don't live with it. It's rarely an emergency, but it never fixes itself. A safety inspection takes about twenty minutes and tells you whether it's a cheap fix or something bigger.
Worn rollers, in most of the noisy-door calls I take. Steel rollers, especially the ones without ball bearings, get louder as they wear and as the track collects grit. Swapping them for sealed nylon rollers is one of the most common jobs we do. A full set installed starts at $130, and a roller replacement usually takes under an hour.
Loose hardware is next. Hinges, brackets, and the bolts holding the track to the frame all back off over years of vibration. A pass with a wrench during a hinge repair visit quiets a lot of doors. Track alignment matters too. If the track has drifted even slightly out of true, the rollers scrape instead of roll, and that scraping goes straight up into the room above.
Springs can be part of it, particularly if you hear a metallic twang or pop as the door opens. Have that checked soon. A spring under strain is a safety problem before it's a noise problem.
Sometimes the door is fine and the opener is doing all the damage. A chain-drive opener pulls the trolley with a metal chain, and that chain sends vibration into the ceiling mount and the framing around it. If your garage has a chain drive and sits under a bedroom, that alone can explain most of what you hear at night.
Belt-drive openers run on a rubber belt and are noticeably quieter, especially for vibration that travels through wood rather than air. I've swapped plenty of chain drives for belt drives in Sunset and Richmond District homes because someone upstairs couldn't sleep through the opening cycle anymore.
Before jumping to a full opener swap, have an opener evaluation done. It's from $45 and comes off the bill if you do the work. Sometimes the noise is a loose mounting bracket or a worn drive gear, and that's a fix from $140 rather than a new unit.
Two things. First, watch the door open and close from inside the garage. Note exactly when the noise happens: at the start, in the middle, or as the door seats at the bottom. That detail helps me diagnose faster when I arrive.
Second, take a flashlight to the rollers and track and look for wear, rust, or debris. You don't need to fix anything. If the rollers look flat on one side or the track has rust streaks, that's a strong hint.
What you shouldn't do is spray WD-40 on everything and hope. It strips the grease that's there and attracts dust, and the grinding gets worse over time. If you want to do your own upkeep between visits, a proper lube and tune service uses garage-door silicone or lithium grease, not a general-purpose spray.
If snugging a few visible bolts doesn't quiet things within a cycle or two, call. Chasing a noise you can't diagnose can eat a weekend, and loosening the wrong thing or overtightening a bracket makes it worse.
For most Sunset and Richmond District homes, I can diagnose and fix a noisy door in one trip. We check rollers, hinges, track alignment, and opener mounting together, since they're usually related. Our Sunset District garage door repair page covers this exact call, and from the shop at 1726 Great Hwy we reach most of San Francisco in about 20 to 25 minutes.
Cost depends on what's wrong. A roller swap and hardware tightening starts at $90. An opener drive swap runs higher. Either way, I tell you the exact price before starting, and I'll tell you if something doesn't need fixing yet.

A little motor hum is normal. Banging, grinding, or a rattle you feel through the floor is not. That usually means loose hardware or worn rollers, and it's worth a look before it gets worse.
Yes. Nylon rollers are the single biggest noise fix we do. Swapping worn steel rollers for sealed nylon ones cuts vibration hard, often within the first few cycles of the door.
You can snug visible bolts with a wrench, but stripped holes or a bent track need a trained eye. Overtightening a bracket can crack it, so if the rattle doesn't stop after one pass, call us.
Yes. Chain-drive openers send the most vibration into the framing. Belt-drive units run much quieter under living space. It's one of the first things I check on these calls.
Most Outer Sunset and Richmond District calls get same-day or next-day service. Call in the morning and I can usually give you an arrival window within the hour.
