On a house from 1957, the most common failure we see is a worn-out extension spring system or a torsion spring that's simply reached the end of its cycle count - these doors have been opening and closing for well over six decades, and springs don't last that long regardless of how well the door was maintained. Rollers and hinges on original hardware tend to be the next thing to go, since they take the daily wear long after the door itself has been repainted or patched.
We'll be straight about one limitation: if the original opening was framed narrow for a single-car door and you want a modern double-wide, that's a structural job, not a swap-out, and it's not something we'd sell you as a quick fix. For straightforward spring, cable, or opener repair on original Lakewood-era hardware, parts are usually available and the fix is the kind of job we do routinely. For anything touching the framing, we'll tell you that upfront before any work starts.
