For a spring or cable failure, the repair is mechanical and fast: we match the spring wind to the door weight and the opener's duty cycle, swap the hardware, and test the balance by hand before we leave. For opener issues tied to cold-thickened grease or worn gears, we service or replace the unit rather than patch it - a gear kit on a 20-plus-year-old opener is often false economy once you add labor, and we'll tell you that straight rather than sell you the kit. One honest limit: if the track is warped from years of freeze-thaw stress at the base plate, we can true it up once, but a track that's been bent and re-straightened more than once usually needs replacing - we won't keep bending the same piece of steel and calling it fixed. We carry common torsion spring sizes and opener parts for the 1962-2008 housing range that dominates this area, so most jobs don't wait on a special order.
