Then Torsion spring replacement.

A torsion spring letting go sounds like something fell in the garage, and then the door refuses to lift. If that happened in Davisville today, we bring the matching spring, replace it as a pair when the door has two, check the cables and bearings beside it, and rebalance the door before we leave.

Our technicians arrive in Davisville ready for the everyday repairs: torsion and extension springs, lifting cables and drums, rollers, hinges, bottom seals, photo-eyes and opener gears.

Every square is one home in a hundred.
Yes, mostly at floor level. Months of slush and road salt reach the lowest hinges, the bottom brackets and the loop of each cable before anything else on the door, so those get a close look for rust. The technician also checks whether the bottom seal has been freezing to the slab, how the drive has coped with cold, stiff starts, and whether frost or salt film has been blinding the sensors near the floor.
A lubricant made for garage doors, applied lightly to hinge knuckles, roller stems and the springs, following the door maker's own recommendation, since the right product and whether bearings are included varies by manufacturer. General-purpose penetrating oils are thin and wash away, and heavy grease attracts grit. Nothing goes on the track raceway or on a nylon or plastic wheel. The opener's chain or screw rail may take a lithium grease according to its manual, and the manual for your door names what its maker prefers.
Where the damage is, at floor level, near the curve or overhead; what caused it if you know, such as a bumper or a ladder; whether the door is closed, open or stuck partway; whether any roller has come out of the channel; whether there is a spring above the door or springs along the tracks; and the door's rough size. A photo of the damaged length and of a bracket with its screws is very useful.
A spring that is intact but has relaxed slightly can be given a little more tension, within limits, to restore balance; this is a normal adjustment on a door that has settled. A spring with a broken coil is replaced as a unit, since the wire has reached the end of its life. The technician checks the condition of the steel and recommends whichever restores a balanced, safe door.
