Heard the bang? Leave it down — we're rolling — across Los Gatos, Monte Sereno, Saratoga, Campbell, Cupertino, Willow Glen, Almaden Valley, Sunnyvale.
A garage door spring retires with a crack that sounds like a shot inside a closed garage. One report, then a door the opener cannot lift and a car going nowhere. Leave it down and call: a wound spring still holds serious stored energy, and this is the repair that sends more weekend DIYers to urgent care than anything else in this trade.
We size replacements from the door itself — measured weight, wire gauge, coil length and inside diameter — because this valley runs from 1920s single-width garages behind Willow Glen bungalows to eighteen-foot three-car doors on Almaden tracts and heavy custom hardwood doors on Monte Sereno and hillside Los Gatos builds. A chart guess fails badly at the heavy end. Coated high-cycle springs, correct turn counts, tested until the door floats level at half-open.
Springs here fail on cycles rather than on weather, and that makes the cycle count the whole conversation. There is no freeze to embrittle the steel and very little corrosion, so a spring in this valley genuinely does last its rated life — which means when it goes, it has simply been used up. A household with three drivers and a commute reaches ten thousand cycles years before a retired couple does, and high-cycle springs are worth their modest extra cost on exactly those houses. We ask how much the door runs before we recommend a set.
True door weight, wire size, length and inside diameter — hardwood and glass included in the math.
The correct spring set in one approved number before anything unwinds.
Winding bars, correct turns, matched pair — by the book, every time.
The door floats at half-open or we keep working, then full opener cycles.
