Identify what your door is doing before you call. If it is one of these, do not keep operating it.
Your torsion spring has snapped under intense torsional load. Forcing the opener to lift the door without spring assistance will burn out the motor or snap the drive belt.
A stripped internal nylon drive gear or a blown starting capacitor. We carry complete carriage gear rebuild kits in our trucks to repair your system immediately.
Don't let a snapped spring, snapped cable, ripped weather seal, or a defective remote keep you locked inside. Our expert teams carry fully stocked dispatch trucks. We regularly perform comprehensive garage door maintenance (inspection, lubrication, adjustment, and component testing) to keep your system safe. We serve Colma and the cities around it.
Sort a garage door into what travels and what does not, and the fixed list runs long: the vertical track fastened up both jambs, the hangers holding the horizontal track off the ceiling behind the opening, the hinge leaves screwed into each section, the brackets at the bottom corners the lift cables dead-end into, the bolts the opener's own mounting hangs on, and — where the counterbalance sits overhead — the end bearing plates and the anchor it is bolted through. None of that is meant to go anywhere. All of it is holding up something that does.
So the fixed list gets settled before anything on the moving one is judged. Where a length of track has drawn away from the jamb, the rollers on that side have somewhere to go that they did not have before, and the rollers are what shows it. Where a hanger has worked loose, the horizontal track carries the door on a line it was not set to, and it comes back as a noise rather than as a hanger. Where a bearing plate or an anchor has shifted, the counterbalance is no longer pulling square to the door it was set for. Tighten and re-line first, then run the door and see what is left, because a part fitted to a door that is sitting out of position goes straight back out of position with it.
The census counts 571 housing units in Colma, and the table it sorts them on is a short one. 253 of them were finished before 1980 and 215 from 2000 onward — 38 apart, with 134 the margin on that difference, so those two ends of the table are not put in any order. The median build year is 1988 and the census carries a margin of 16 years on it, so even the midpoint of this stock is a span of years rather than a date. Where the table does separate two of its own rows, it does it a decade at a time: 109 of these homes date from the 1950s against 34 from the 1960s, 75 apart with 53 the error on that comparison.
Decades are as fine as those rows get, and what decides a call is finer than that by a long way — one bolt in one jamb, and whether it is still where somebody put it. Nothing gets chosen before that list has been read, and once it has been, the reading is what does the choosing.
