We stock steel panel sections in the common residential widths and the standard color range, along with the hardware that goes with a panel swap - hinges, end stiles, and the fasteners that are usually corroded past reuse on a door this old. For homes with doors from the 1960s-70s stock that makes up most of this area, these are the sizes we pull first.
What we don't keep on the truck: matches for discontinued wood-panel profiles or older aluminum doors from the earliest end of the 1938-1991 build range. Those get special-ordered, and we'll tell you honestly if that means a wait instead of a same-visit fix.
Given the cold-climate conditions this area sees, we default to steel gauges rated for that kind of temperature swing rather than the lighter panels builders sometimes used decades ago. A panel that flexes less in deep cold holds its seal better and cracks less at the seams over time.
