A straight swap on a Gilberts house - same size opening, same track position - usually runs half a day once the door is on the truck. Where it slows down is the ordering, not the labor. Gilberts homes were mostly built after 2004, which means openings are standard modern sizes, but the builder-grade doors that shipped with these houses twenty years ago are often a size or panel style that's been discontinued. We measure on site, order the exact door, and schedule install for when it lands - we don't stock a warehouse of pre-cut panels in Gilberts because we're not based here. If your opening is non-standard or you're widening it, add a day for header work. That's the honest range: same-day labor, but the door itself dictates the calendar.
