We carry the springs, cables, rollers, and hinges that fit the torsion hardware common on houses built in the late 1990s, since that's what shows up on most calls in San Juan. Standard-size torsion springs, nylon rollers, and galvanized cable are truck stock - no waiting. Where we run into delay is a specific opener logic board for a brand that's since changed its part numbers, or a custom-width door panel that isn't a stock size. Those get ordered, and we'll tell you the lead time instead of guessing. If your door is original to the house, there's a decent chance the track width or spring wind is a size we carry - but we confirm that on site rather than promise it over the phone.
