Most single-panel jobs run one to two hours once we're on site, assuming the panel is in stock or was pre-ordered from your photos. If we have to source a panel that matches a 2006-era model no longer in regular production, the visit for measuring and ordering is separate from the install, and there's a wait on the part in between - that's the honest limitation here. We're not going to promise a same-day fix on a panel we don't have on the truck.
Once the part's in hand, the job itself is straightforward: pull the damaged panel's hinges and rollers, swap the section, reset the hinges, and check the door balance afterward, since a new panel changes the door's weight distribution slightly even when it matches the old one closely. On insulated doors we also reseal the panel joints, since a loose seam is where Sahuarita's summer heat gets into the garage fastest.
