A spring almost always breaks on the coldest morning, right when you are late for work. The bang is loud, the door will not budge, and the temptation to force it is strong. Here is the calm, safe version of what to do next.
Most broken springs announce themselves with a single loud bang, like a muffled gunshot from the garage. People in Oconomowoc and Delafield call us all the time saying they thought something fell off a shelf, then found the door would not open an hour later. The spring stores all the lifting energy, so the moment it snaps, that energy releases at once.
After the noise, the tells are simple. Look at the torsion spring mounted on the steel shaft above the door opening. A broken one shows a clear two-inch gap where the coil separated. If your door uses extension springs along the horizontal tracks, you will see one hanging slack or snapped in two. The door itself feels dead heavy, the opener strains and hums, and sometimes the opener lifts the door a few inches and gives up.
The single most useful thing you can do is nothing dramatic. Leave the door in whatever position it is in, almost always closed, and keep people and cars clear of it. A door with a broken spring can drop fast if anything dislodges it, and that is how feet and fingers get crushed. Then work through these steps in order.
If your car is stuck inside and you have no other way out, that is a true emergency, and our after-hours line handles stuck-door calls across Lake Country with a 30-minute callback.
This is the part that sends people to Waukesha Memorial every winter. A torsion spring stores enough energy to lift a quarter-ton door, and that energy does not care about your good intentions. Here are the moves that turn a routine repair into an injury or a bigger bill.
Do not try to lift the door by hand to get your car out. With the spring gone you are deadlifting up to 250 pounds over your head, and if your grip slips the door guillotines down. Do not run the opener repeatedly hoping it will catch. The opener is built to move a balanced door, not to deadlift the whole weight, and you will strip the gear, snap a lift cable, or burn the motor, which turns a $300 spring job into an opener repair on top of it.
Above all, do not buy a spring online and wind it yourself with a couple of screwdrivers, which is the single most common cause of do-it-yourself garage injuries we hear about. Winding bars under load will whip back and break a wrist if they slip, and getting the wrong wire size means the door slams or never balances. The savings are not worth a trip to urgent care.
Lake Country springs lead a harder life than the box admits. A torsion spring rated for 10,000 cycles in a lab often gives out closer to 7,000 cycles here, because the freeze-thaw swing from October through April works the steel cold and brittle. Cold metal flexes less and cracks sooner, and the humidity coming off Lac La Belle and Pewaukee Lake speeds up surface rust that becomes a fracture point.
Do the math on a normal household. Four to six door cycles a day, every day, eats through 7,000 cycles in roughly six to eight years, not the fourteen the cycle rating implies. That is why so many of these springs fail right around the same age, and why we often recommend swapping both springs of a matched pair at once. If one is six years old and tired, the other is days behind it. We dig into the lifespan question in our Wisconsin spring lifespan guide.
The job is fast in trained hands. We measure the wire diameter, the inside diameter, and the length of the old spring, match it to a part sized for your door weight, then wind the new spring to the correct tension with proper winding bars and balance the door so the opener barely works. We test the safety reverse on the photo-eyes before we leave. A single torsion swap takes 45 to 75 minutes; a matched pair about 90.
On price, a single torsion spring usually runs $220 to $320 installed, a matched pair $320 to $420, and an extension spring swap $180 to $280. The $89 diagnostic is applied toward whatever repair you approve, so a confirmed spring job costs you the spring price, not the diagnostic on top. For the full Lake Country breakdown, see our spring repair cost guide or the cost page. Ranges depend on door size and parts on hand the day we visit.
The clearest sign is a loud bang from the garage, often on a cold morning, followed by a door that will not open or feels far too heavy. Look at the torsion spring above the door for a two-inch gap, or check whether an extension spring along the track has snapped. The opener may strain, hum, and quit.
You should not. The spring carries almost all of the door weight, so with it broken the door can weigh 150 to 250 pounds with nothing holding it up. Lifting by hand risks a crushed hand or foot, and running the opener can burn out the motor or snap a cable. Leave it down and call for service.
Torsion springs hold enough stored energy to break a wrist or worse when they let go, and the winding bars can fly loose if a step is missed. Most spring injuries treated in emergency rooms come from do-it-yourself winding. We carry the right springs sized to your door and finish most jobs in under 90 minutes.
A single torsion spring swap usually takes 45 to 75 minutes once the technician is on site, and a matched pair runs about 90 minutes. We measure the wire size, inside diameter, and length, wind the new spring to the door weight, balance the door, and test the safety reverse before we leave.
A single torsion spring usually runs $220 to $320 installed, and a matched pair $320 to $420. Extension spring swaps usually run $180 to $280. The $89 diagnostic is applied toward the repair. See the cost guide for the full Lake Country breakdown.
