Falcon Heights runs about 2,041 households, which is small enough that install jobs here come one house at a time rather than in matching runs the way they might in a bigger suburb. That size matters because it means less uniformity, not more - a 1960 rambler two doors down from a 1975 split-level can have two completely different opening widths and framing setups.
Most houses in this town went up around 1960, a decade earlier than the wider service area's 1952-2003 range settles toward its 1975 median. That earlier build date usually means narrower door openings sized for the single-car garages common in that era, non-standard jamb widths, and framing that was never built to carry a heavier insulated section. A door that installs clean in a newer house down the road can hit blocking or a short header here.
The region also sits in a severe cold climate band. On a 1960-era opening that was framed for a light, uninsulated wood door, swapping in a modern steel sandwich door changes the load on that old header more than most homeowners expect. We check that before we quote, not after.
