Matching the right spring
Door weight, height, drum size and the lift arrangement decide which spring fits. Two coils that look alike can be rated completely differently.
A broken spring turns a balanced door into dead weight, and the opener is not built to lift it. Leave the door where it is and let Katy Garage Door Service check the springs, cables, drums and bearings before any part is replaced.
Wide double doors are the norm on Katy homes, and the heavier the door the more the spring has to carry. Katy Garage Door Service weighs the door against the spring that is actually fitted rather than replacing like for like on sight.

Not every visit needs every item below. The diagnosed repair is kept separate from anything optional, so you can see what is required and what is a recommendation.
Door weight, height, drum size and the lift arrangement decide which spring fits. Two coils that look alike can be rated completely differently.
Cables, drums, center bearings and end bearing plates are inspected while the system is apart. A rusted bearing will wear a new spring early.
After fitting, the door is cycled, balanced by hand and tested against the opener's force and reverse settings. The motor should never be compensating for a heavy door.
The quote should name the failed component, the compatible replacement and any related wear found during the inspection. Springs are usually fitted in matched pairs on a double door, because leaving an old coil next to a new one puts the door back out of balance within months.
Spring failure also exposes other faults: a snapped coil often drops the door hard enough to need cable and roller work or off-track repair at the same visit. If the opener has been forcing a heavy door for weeks, ask about opener repair too. Where the door itself is old or rusted through at the bottom, the repair versus replacement guide is the better starting point.

Spring size and rating, whether one or both coils are replaced, and any cable, drum or bearing damage found alongside the break. Katy Garage Door Service prices the work at the property once the door has been inspected, and you approve it before anything starts.
Usually yes. Common torsion sizes are stocked, so most spring calls are finished in one visit. An unusual lift arrangement or a rare high-cycle spring may need ordering, and Katy Garage Door Service will tell you that at the inspection.
No. A torsion spring holds enough stored energy to cause serious injury if the winding bars slip, and the door can drop without warning. Keep everyone clear of the opening and let a trained technician secure the door first.
Stop using it. With a broken spring the opener is dragging the full weight of the door on its rail and gears, which usually turns one repair into two. Park outside and arrange an inspection instead.
