Professional torsion and extension spring replacement using high-cycle calibrated replacement springs for residential and commercial systems.
Overhead garage door systems rely on balanced counterweight mechanisms to function. Torsion springs, mounted on a steel shaft above the door opening, store immense rotational energy. Extension springs, running parallel to the horizontal tracks, stretch to hold weight. When these components fail, the system is rendered inoperative, and attempts to open it manually can result in severe damage to the top door panel or the opener assembly.
Our technicians utilize professional winding charts and wire gauge calipers to determine the exact spring matches required for your door weight. We do not use generic or undersized springs; instead, we install high-cycle replacement coils engineered for durability in Canadian weather conditions. If you need a spring replacement, we handle the extraction of broken coils, mounting of new coils, and shaft balancing safely.
Torsion springs are under extreme mechanical tension. Winding them requires professional winding bars, tension blocks, and an understanding of spring diameters and coil length ratios. A mismatched spring will either prevent the door from closing completely or make it too heavy, stripping the opener's internal gears. Our services ensure that both springs are replaced in pairs to maintain even tension distribution across the shaft, extending the life of your entire system.
Extension springs rely on safety cables running through the center of the coils. If an extension spring snaps without a safety cable, the metal coil can fly loose, causing severe property damage. We inspect and install steel safety cables with every extension spring replacement. We also examine the center support bearing, end bearing plates, and shaft keyways to ensure the entire counterweight system is aligned and calibrated.

Understanding the mechanical design and load distribution of your residential or commercial garage door system is essential to maintaining high safety standards.
Torsion springs are rated by cycle life, typically starting at 10,000 standard cycles. One cycle equals opening and closing the door once. Over years of use, the spring steel wire undergoes microscopic stress and fatigue. Rust, cold temperatures, and moisture accelerate this decay. When the metal reaches its elastic limit, the coils snap with a loud report. Upgrading to high-cycle springs (25,000+ cycles) is recommended for high-use residential doors to double operational longevity.
Every garage door has a unique weight and radius configuration. Calculating the correct spring replacement requires measuring three main metrics: the wire size (using a 20-coil wire caliper), the inner diameter (commonly 2.0 inches for residential doors), and the overall wind length. Installing a spring with a slightly different wire diameter or length alters the torque curve, meaning the door will not balance at mid-travel. We calculate the exact IPPT (Inch-Pounds Per Turn) to match your door specifications.
We secure the door to the track using locking pliers, disable the motor drive, and slowly release any remaining tension on the unbroken spring using certified winding bars.
We loosen the setscrews on the winding cones, slide the shaft, and extract the broken springs. We inspect the center support bearing and end bearing plates for wear.
We mount the new high-cycle springs, slide the shaft back into place, wind the coils to the calculated number of turns, and test the door balance manually.
