A standard maintenance visit - spring tension check, roller and hinge inspection, track alignment, lubrication, opener force and limit check, cable and hardware look-over - runs under an hour on most single doors and not much longer on a two-car door, assuming nothing's seized or stripped. If a roller's cracked or a cable strand is frayed, we'll flag it on the spot rather than swap it mid-visit without talking it through first, since that changes the scope and the cost. We don't pad the visit with upsells. If the door checks out clean, you'll hear that too. The one honest limit here: if a part needs ordering - a specific opener logic board, say, or a spring size we don't carry on the truck that day - the fix becomes a second trip, not a same-visit swap. That's rare on 2000s-era hardware, which is still common enough that we stock for it, but it happens.
