We stock the panel sizes, track, and spring stock that match what actually goes up in homes built across the Madison service area's 1976-2012 run, and Harvest's newer stock - mostly early-to-mid 2000s construction - lines up well with what we carry on the truck. Standard 16x7 and 9x7 openings, torsion spring setups sized for insulated steel doors, and the openers that pair with them are not special-order items for us. Where it gets slower is anything custom: a non-standard width, a specific insulation rating, or a color or window-pattern order outside our regular stock. Those go on manufacturer lead time, and we'll tell you that number when we quote it rather than guess. Given the winters here - cold enough that insulation rating actually matters for the door, not just the house - we steer most Harvest installs toward insulated steel over a bare single-layer door. It costs more up front and it's worth it for a door that sits exposed to that cold half the year.
