On a Winchester job, the truck comes from Richmond carrying the hardware sized for the 1970s-style double openings that make up most of what's out here - steel insulated sections, standard torsion springs, standard track. The crew pulls the old door, sets the new one, balances the spring tension for the door weight, and tests the opener if you're keeping the existing one. One honest limit: if your home is on the older end of the range, with a narrower single-car opening or non-standard header height, that's a less common call in Winchester and may need a measurement visit before the install date gets set, since we'd rather confirm the opening than guess and bring the wrong door.
