Garage Door Track Repair in Los Angeles
A door that catches at exactly the same height on every single run is telling you something about geometry rather than power. The pair of steel rails it travels in go vertically up the jambs and then curve back horizontally across the ceiling. It has no moving parts and it is easy to overlook entirely, right up to the point where a few degrees of misalignment start binding the door, chewing rollers and eventually throwing the whole thing out of the rail.
Track work starts at $95 and is usually done on the first visit.
Signs the Track Is the Problem
A door that binds or slows at the same point in its travel every time is the clearest one, since a mechanical problem that repeats at a fixed height is almost always geometry rather than power. Visible gaps between a roller and the rail, a door that rubs against the jamb on one side, scraping or squealing concentrated in one part of the run, or a rail you can rock by hand because its brackets have worked loose. Look along the vertical track from below as well, since a bend that is obvious end on is invisible from the side.
Bent, Loose and Out of Plumb
Three different faults get called the same thing. A bent rail has been struck by something, usually a bumper or a ladder, and either straightens or gets replaced depending on how sharp the kink is. A loose rail has simply vibrated its lag bolts out of the jamb over years of cycling, which is common on the older timber framed garages throughout this city and is fixed properly by moving to sound timber rather than retightening into a hole that has given up. An out of plumb rail is the subtle one, where a garage has settled and the jamb is no longer square, and correcting that means shimming the brackets rather than forcing the rail.
Track Spacing and Roller Depth
The two rails must sit parallel and at the correct distance from the door, and the rollers must run at the right depth in them. Too tight and the door binds and the rollers seize. Too loose and the door rattles, leans and eventually jumps out. Our technician sets both against the door rather than by eye, and adjusts the top roller brackets so the door seals properly against the header at the same time, which is the adjustment that quietly fixes a great many draught and light gap complaints.
The Horizontal Track and Its Hangers
The rear of the horizontal track is carried on hangers bolted into the ceiling structure, and these deserve a look on any older garage. Hangers fixed into a single joist, or worse into drywall, sag over the years and let the back of the rail droop, which makes the door hesitate as it flattens out at the top of its travel. Where somebody has hung storage or a bicycle from the track, and people do, the rail is usually distorted and the hangers need doing properly before anything else will hold.
Costing Rail Work
Realigning and resecuring existing track starts at $95. Replacing a bent vertical rail starts at $95 a side and a horizontal section from $125. Where the track problem has already put the door out of its rail, our off track repair page covers that and the two are normally done together. Rollers damaged by a bad rail are usually worth replacing at the same time. Everything is quoted before the work starts and nothing is added afterwards. Rail damaged beyond straightening is usually replaced with the door rather than on its own, which our garage door installation page covers.
