Heard the bang? Leave it down — we're rolling — across Scarsdale, Bronxville, Hartsdale, White Plains, Eastchester, Larchmont, Mamaroneck, New Rochelle.
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 that is not making the 7:18 into Grand Central. Leave it down and call: a wound spring still holds serious stored energy, and this is the repair that sends more weekend DIYers to the emergency room than anything else in this trade.
We size replacements from the door itself — measured weight, wire gauge, coil length and inside diameter — because this county is full of doors that no chart covers. A 1927 Scarsdale carriage garage, a Bronxville garage cut into a hillside, a modern insulated replacement hung in an original opening: all three need the spring calculated from the door on a scale. Coated high-cycle springs, correct turn counts, tested until the door floats level at half-open.
There is a specific hazard on very old installations: extension springs with no containment cable running through them. That was normal practice for decades and a great many original Westchester garages still have it. When an uncontained extension spring breaks it does not simply fail — it whips, and it can put a piece of steel across a garage at speed. Whenever we find one we say so plainly and fit safety cables as part of the work, because that is not an upgrade, it is a missing safety component.
True door weight, wire size, length and inside diameter — original timber and insulation included in the math.
The correct coated spring set, with safety cables where they are missing, in one approved number.
Winding bars, correct turns, matched coated pair — by the book, every time.
The door floats at half-open or we keep working, then full opener cycles.
