Torsion Spring Replacement in Central Florida
The torsion spring above your door does nearly all the lifting. It is a precision part: wire size, coil count and length must match the door weight, or the door will be heavy, jerky or dangerous. We measure your door, fit the correctly rated spring, and balance the whole system before testing.
How a Torsion System Works
When the door closes, the torsion spring winds tighter and stores energy. When the door opens, the spring unwinds and that energy lifts the door, with the cables winding onto drums at each end of the torsion tube so both sides rise together. The opener contributes only a small part of the force; a balanced door should stay put when lifted halfway and released.
- Torsion tube: the shaft the spring and drums sit on, carrying the whole lifting load.
- Winding cones: the fittings at the spring ends that set and hold the tension.
- Drums: grooved wheels that wind the lift cables evenly as the door rises.
- Centre bearing and end bearings: the supports that let the tube turn smoothly.
Signs the Torsion Spring Is Failing
- The door rises unevenly, with one side lagging behind the other.
- The door feels heavy, or drifts down when left halfway open.
- A gap in the coil, rust flaking from the spring, or a bang from above the door.
- The opener labours, stops mid-travel, or reverses for no clear reason.
Our Process
Step 1: Secure and measure
The door is clamped shut, the opener is disconnected, and the door weight, height and existing spring dimensions are recorded.
Step 2: Select the spring
A replacement is chosen by wire size, length, inside diameter and cycle rating to match the door, not merely to fit the tube.
Step 3: Fit and tension
The spring is wound to the correct number of turns, set screws are tightened, and drums, cables and bearings are inspected.
Step 4: Balance and test
The door is checked for balance halfway up, run through full cycles, and the opener limits and safety sensors are verified.
What Affects the Price
Spring specification and cycle rating, single versus pair replacement, door weight and height, and the condition of drums, cables and bearings. The written quote lists each item so you can see what is included before approving.
Safety Note
Torsion springs are tensioned with winding bars and must never be adjusted with screwdrivers, pliers or other household tools. A slipping winding bar can release the spring violently. This is a job for trained hands and the right equipment, every time.

Frequently Asked Questions
What is a torsion spring, and how is it different?
A torsion spring is the tightly wound coil mounted on a tube above the door. It twists as the door closes, storing energy, and unwinds to lift the door as it opens. Extension springs, by contrast, stretch along the sides of the door. Torsion systems are the standard on most modern sectional doors because they lift more evenly.
How do you choose the right torsion spring?
By measuring the door height and weight, the track radius, and the existing spring wire size, coil length and inside diameter. A spring that is too weak will not lift the door, and one that is too strong will slam it or strain the opener. Matching is done from measurements, never from a guess.
What are winding cones, drums and cables doing here?
The spring sits on a torsion tube with a winding cone at each end, and lift cables wind onto drums at the ends of that tube. When the spring turns, the drums wind the cables and lift the door evenly from both sides. A worn drum or frayed cable upsets that balance, so both are checked during every spring job.
How long does a torsion spring replacement take?
Most torsion spring replacements are completed in a single visit once the correct spring is confirmed. The visit includes securing the door, fitting and tensioning the spring, checking drums and cables, balancing the door and testing the opener and safety sensors through full cycles.
