Torsion Spring Replacement in Zephyr

Once or twice a year is a good rhythm, with autumn the most useful time because cold thickens grease. Use a garage-door lubricant, typically a silicone or lithium spray, applied along the coils so it works between them as the door cycles. Hinges, roller bearings and the end bearings benefit from the same treatment. Keep the track itself dry, since lubricant there gathers grit and slows the rollers.

Cold makes steel slightly less forgiving and thickens the grease on the coils, so a spring that has already used most of its cycle life is more likely to let go on a frosty morning when the door is first opened. The cold is the final straw rather than the cause; the underlying reason is fatigue from years of cycles, sometimes helped along by rust and dry coils.

Oil-tempered springs are the traditional dark grey or black coil; they hold their tension well over time and are widely used. Galvanized springs have a zinc coating that resists rust, which is useful in damp garages, though they tend to relax slightly and may need a small adjustment after settling in. Both are available in standard and high-cycle ratings, and the technician can explain which suits your garage.
