A garage door gives you weeks of warning before it quits. The trouble is that the warnings are quiet: a slower lift, a new grind, a door that sits a little crooked. We take calls from all over San Francisco at our shop at 1726 Great Hwy, and most of the emergencies could have been a scheduled daytime visit if the owner had acted on one of the nine signs below. Two of them are dangerous. Those are marked.
Slow means strain. The springs are losing tension, or the opener is hauling weight it shouldn't. On a heavy old Sunset door, that extra load strips the opener's drive gear, and a gear job from $140 turns into a new opener.
Grinding is rollers. Popping is usually a spring or a hinge. A rattle you can feel upstairs is loose hardware. Noise is the first warning before a part breaks, and in a tuck-under garage the bedroom hears it first. A set of nylon rollers starts at $130 and fixes most of it.
A door that stops halfway or reverses is usually a sensor, a travel-limit setting, or a bent track. Sensor cleaning and realignment starts at $90. If the same door has done this three or four times in a year and it's past 20 years old, garage door replacement can be the cheaper decade.
One side rising faster than the other means a cable is stretching or one spring is weaker than its partner. Keep using it and the door jumps the track. A cable pair starts at $160. An off-track re-seat with bent parts starts at $165. Catch it at the first step.
Frayed cable strands at the bottom bracket, rust bloom on the spring coils, a bent track, a hinge with a crack at the knuckle. These parts carry the door's full weight under tension. On the west side, salt fog rusts cables and springs years early, so look twice a year with a flashlight. Don't touch a frayed cable or a spring. Call.
If new batteries don't fix it, the problem is the wiring, the sensors, or a failing logic board. A board starts at $190, and a board that's dying tends to quit for good after the next power flicker. Building managers see this on shared doors too, where one dead opener locks out a whole building. Our commercial garage door repair in San Francisco page covers those.
Jerking means the rollers are catching in a track that's out of true, or a hinge is binding. Each jerk bends something a little more. Track realignment starts at $130 if we get to it before a section has to be replaced.
A door that drops is a door whose springs are failing. Springs carry the weight, and when they weaken the door can slam shut on a car, a pet, or a hand. Stop using it and get the springs replaced: from $189 for one torsion spring, from $320 for the pair. Our broken spring repair page explains what happens on the visit.
Pull the release cord with the door closed and lift. If it's dead weight, the springs are done. Every cycle after that is the opener doing a job it wasn't built for, and it's the fastest way to turn one repair into two.
Pick the sign that matches your door and call before it becomes the next one on the list. Slow, noisy, and uneven doors can wait for a daytime slot this week. Frayed cables, a dropping door, or a door hanging crooked should be left closed and looked at today.
