Extension Spring Repair in West Kendall
Extension spring repair covers the springs that stretch along both sides of the horizontal track, above the car. A broken one looks like a loose coil resting over the hood rather than a neat stretched spring. The safety cable running through the spring is what keeps a broken coil from flying. Leave the door parked, and do not touch the coils.
How a broken side spring looks
The healthy spring is stretched beside the horizontal track when the door is down, and it contracts as the door rises. When it breaks, you see a loose coil above the car and the door may hang heavy or crooked. The safety cable may still be in place holding the broken pieces, or it may have been missing for years. Color bands painted on the coil are not a full specification of the spring you need.
Leaving the coils alone
Park the door if it will sit still, and keep people out of the bay until the spring is replaced. Do not touch the coils, the pulleys, or the safety cable in an attempt to hook anything back together. A torsion cone on a shaft above the door belongs to a different system from the springs beside the track.
Replacing the spring and the safety cable
The visit identifies the spring from the door, not from the paint bands, and replaces the broken side. The safety cable is renewed with the spring so a future break stays contained. The matching spring on the other side is checked, because it has stretched the same number of times. Pulleys and clips that the cable runs through are inspected for grooves that would cut a new spring.
How this layout differs from torsion
These springs work by stretching, and they sit beside the track rather than on a shaft above the opening. Hardware, clips, and pulleys are specific to that stretch, and shaft parts will not interchange with them. Older single-car doors used this layout often, while many newer double doors moved to a torsion shaft. The safety cable is easy to miss because it hides inside the coil until the day the spring breaks.
Where side springs still show up
Newer two-car tract slabs in this area more often carry torsion springs, so an extension pair is the less common layout to mention when you have it. A west-facing roof still heats the bay, and high daily cycles stretch those side springs until one lets go. Heat does not change the layout, but it does age the coils faster on a door that runs all day. An occasional gate outside the garage has nothing to do with which spring system is over the car.

Common questions
What does a loose coil above the car mean?
It usually means an extension spring beside the horizontal track has broken. The safety cable is supposed to hold the pieces so they do not fly across the bay. Park the door and leave the coils untouched until they are replaced.
Can the color bands on the spring be used to order a match?
The painted bands are only a rough clue. The spring is identified from the size and weight of the door. Both sides are compared so the new spring works with the one that has not broken.
Will a torsion spring part fix an extension spring?
A torsion cone does not repair this layout. Extension springs stretch beside the track and use their own pulleys, clips, and safety cable. The visit brings those parts when the broken coil is beside the car.
