Broken Garage Door Spring Replacement in Bloomington

Much of Bloomington was built between the 1950s and the 1970s, and many of its garage doors are on their second or third set of springs. Springs wear out by count, not by calendar: every open-and-close cycle fatigues the steel a little more, and a worn spring often gives out on a cold morning. The usual sign is a loud bang from the garage, followed by a door that won't lift more than a few inches.

Not every Bloomington door uses the same system. Most run torsion springs, mounted on a shaft above the door, which twist to store the energy that lifts it. Some older doors still use extension springs that stretch along the horizontal tracks on each side, which depend on a safety cable through each spring to keep a break from sending it across the garage. When we find an extension system, we don't replace it like for like. We convert the door to torsion, which gives a smoother, more controlled lift and keeps the spring's stored energy contained on a shaft above the opening. The conversion is quoted before any work begins, and if it needs parts we don't carry on the truck, you'll know the timing up front.

How long a spring lasts comes down to its cycle rating. Standard-cycle springs are typically rated around 10,000 cycles, roughly seven years at four open-and-close cycles a day. High-cycle springs rated at 20,000 cycles or more cost more up front but last proportionally longer, which can make sense when the garage is the household's main entrance. On a two-spring door we replace both: they've run the same number of cycles, and the one that didn't break is usually close behind.
