A standard maintenance visit, lubing, tightening, balance check, cable and roller inspection, doesn't take the door out of service at all. We work it section by section while it still opens and closes between steps. If we find a spring near the end of its cycle life or bearing plates worn enough to need replacing, that's a different job and we'll tell you before we start, not after. Because we're driving in from Everett, about 16 miles out, we don't offer same-day emergency slots here the way we might for calls closer to the shop. If your door is stuck shut or open, plan for it to be out of commission until the scheduled visit, not fixed within the hour.
