The Role Springs Play in Your Door
Your door's weight is carried by its springs, either torsion springs on a bar above the opening or extension springs alongside the upper tracks. They do the heavy lifting while the opener merely steers the movement. Once one snaps, the door becomes too heavy to raise safely, whether by hand or by motor.
In Athol, MA, the telltale sequence is a sharp bang from the garage, then a door that stays shut or lifts only a few inches before the opener labors and quits.
Why This Repair Calls for Professionals
Even with the door closed, springs hold a large amount of stored force, which is why they injure people who handle them without proper tools or training. Trying to muscle a door up on a broken spring risks having it crash down without warning.
Letting the opener push against a broken spring, even for a short time, overloads its motor and gears. Keep trying, and a simple spring job can grow into a spring-and-opener bill.
How We Work
Match the Spring
We determine whether your door runs on torsion or extension springs, then measure wire gauge, coil diameter, and length to select the right replacement.
Lock the Door in Place
Before touching the spring, we brace the door so it cannot slip or drop while we work.
Swap in the New Spring
With proper winding bars and technique, the failed spring comes out and a new one, rated for your door's true weight, goes in.
Tune the Balance
We fine-tune tension until the door holds still at the halfway point, which spares your opener needless effort.
Cycle and Verify
The door runs through several complete openings and closings so we can confirm it moves quietly and stays balanced.
What to Expect
In most cases the fix is finished during a single visit on the same day. Our trucks carry a good selection of common torsion and extension springs, so return trips are rare. From the moment we arrive to a fully balanced door, plan on about one to two hours, depending on how your door is set up.

Frequently Asked Questions
Each spring is built for a set number of cycles, commonly around 10,000, and eventually fatigues from ordinary use. Harsh temperature changes and a lack of lubrication can hasten the end.
On a door with two torsion springs, we usually advise replacing both. The survivor is typically near the end of its life, and a matched pair keeps the door lifting evenly.
It is best not to. With no spring help the door is very heavy and can fall suddenly, and making the opener lift it can damage the motor and gears.
Good replacement springs are typically rated for 10,000 to 20,000 cycles. For an average household that works out to roughly seven to fifteen years, depending on daily use.
We would not recommend it. Torsion springs hold enormous tension, and mistakes have led to serious injuries. Of all door repairs, this one benefits most from professional tools and experience.
A loud snap followed by a door that will not lift, or that rises only slightly before stalling, points to the spring. A visible gap in the coil of a torsion spring settles it.
