Torsion Spring Replacement: questions about the price

Most residential replacements are completed in one visit. Securing the door, measuring, removing the old spring, fitting and winding the new one, balancing and testing the opener typically takes an hour or two, longer if bearings, cables or a bent top section are also being dealt with. The technician confirms the scope after the first checks, so you know what the visit involves before the work starts.

Spring finish

Oil-tempered and galvanized springs suit different garages. A coated or galvanized spring for a damp or salt-exposed space is a choice the customer can make when the specification is discussed.

Spring specification

The wire size, inside diameter and length that the door's weight and height demand determine which spring is fitted. Larger doors take larger springs, and unusual combinations may need specially wound coils.

Damage from the break

If the opener was run against a broken spring, the top section may be bowed, the trolley bent or a hinge strained. Correcting these so the balanced door runs on straight hardware adds to the scope.
