Noisy Garage Door Repair in Los Angeles
A loud garage door is a genuine domestic problem in this city, where a very large number of houses have a bedroom directly above the garage and somebody leaving at half past five. It is also, in most cases, considerably cheaper to fix than people assume, because the opener usually is not the culprit.
We diagnose and quieten noisy doors across Los Angeles from $85, and a great many of these calls end with a set of rollers rather than a new motor.
Reading the Noise
Different noises mean different things and it is worth knowing which you have. Grinding or rumbling that runs through the whole travel is worn rollers or dry bearings. A rhythmic squeal, once per revolution, is nearly always an end or centre bearing on the torsion bar. A sharp bang or pop at the same point each time is a cracked hinge snapping under load as the door crosses the track curve. A rattle that sounds like the whole door is loose is exactly that, being nuts and brackets that have vibrated free over years. A scraping concentrated in one spot is the door rubbing where the track is out of alignment. And a straining hum from the ceiling is the opener fighting a door the springs are no longer holding.
Rollers Are the Usual Answer
The plain steel rollers most builders fit are the loudest and shortest lived option available, and after a decade in a hot Los Angeles garage their bearings are dry and running metal on metal. Swapping a full set for nylon rollers on sealed bearings is $85, takes under an hour, and is transformative often enough that customers ring backto say the door now sounds broken because it is so quiet. Our roller replacement page has the detail.
Bearings, Hinges and Loose Hardware
The three bearings on a torsion assembly are cheap and they squeal loudly enough to be mistaken for the opener, which is why a good number of people arrive at us having already priced a new motor they do not need. Cracked hinges bang, and they also escalate into panel damage if left. Loose hardware is the easiest of all, since a garage door works thousands of cycles a year and every one of them vibrates every nut on the assembly, so simply going round the whole door with a socket makes a noticeable difference and is included in a tune up.
When the Opener Really Is the Problem
Where the door itself is quiet when moved by hand and the racket only appears under power, the opener is the suspect. Chain drives are loud by design and always will be. A stretched chain slaps the rail. A worn drive gear rattles. Where a bedroom sits over the garage and the opener is a fifteen year old chain unit, a belt drive is a transformation and a wall mounted jackshaft unit, which takes the motor off the ceilingentirely, is quieter again. Our opener installation page covers both.
Structure Borne Noise
One last cause worth knowing, because it fools people. An opener bolted rigidly to ceiling joists transmits vibration into the floor above rather than into the air, so the noise is worse in the bedroom than in the garage. Fitting rubber isolation pads at the mounting points and at the header bracket costs very little and often does more than a new opener would. Our technician checks for this before recommending anything expensive. Diagnosis is $85, comes off any work agreed, and most noise jobs settle between $85 and $250. Almost all of this is caught by a yearly service before anybody in the house has started noticing it, which our garage door maintenance page describes.
