Replacing snapped torsion or extension springs on Randolph doors, often after the first hard freeze of the season.
In Randolph the classic spring call comes on a frozen morning. Someone heads out to the garage before work, hears that the opener is straining, and finds a gap in the coil above the door. Higher elevation means colder nights than the towns along Route 287, and spring steel that has been cycling for years is at its weakest when it is cold. Most of the township's attached two-car garages use torsion springs on a bar over the door, while some older single doors from before the big growth years still run extension springs along the tracks.
If a spring has broken, leave the opener alone. With two-car doors common across Randolph, the door may weigh well over 150 pounds, and the opener was never meant to lift that on its own. Pressing the button again can strip the opener gear, bend the top section, or unwind a cable from its drum, which turns a spring job into a bigger repair. If the car is trapped, tell the contractor when you call so they can talk through options, and keep children and pets away from the door in the meantime.
The technician will measure the old spring, match wire size, length and inside diameter to the door, and wind the new set properly. On a door with two springs, replacing both is usually the sensible choice, since the second one has seen the same winters and the same cycles. Families who use the garage as the main entrance many times a day may want to ask about higher cycle springs. Afterward the pro should show you that the door stays put when lifted halfway by hand, and point out any worn rollers or cables with a separate price.
A spring that is near the end of its rated life is under the most stress when the steel is cold. Randolph's higher ground gets those cold snaps early and often, so a tired spring tends to give out then rather than in summer.
They might be, but many Randolph homes of that age have had at least one spring replacement already. A technician can tell from the springs and hardware what has been changed and whether the springs suit the current door weight.
Do not try to lift a door with a broken spring by hand or with the opener. Call the contractor, explain that the car is inside, and ask what they suggest. If you need to get somewhere urgently, arrange other transportation.
