Most sectional overhead doors are counter balanced with a torsion spring. This part is one of the most misunderstood parts on a garage door.
A broken torsion spring, like the one shown above, has a clear separation where the spring coil has broken and retracted. Winding a spring, and conversely unwinding a spring, should be a simple thing to do but there are many factors to take into account that are completely missed by the novice such as drum size, drum type, track radius, torsion tube placement, wire size, inside wire diameter, cone type, … etc. But why risk your safety when qualified repair persons are readily available.
When a spring breaks…. call a pro ! Get a quote in writing BEFORE the professional starts his work. Depending on your region the cost to replace a pair of springs on a double car size sectional garage door should be about $ 300.00. Generally the total is calculated as the going labor rate plus the cost of the springs, plus tax.
