Cumming sits about 10 miles out from our Buford base, so booking an install here means working it into the day's route rather than treating it as a separate stop. We ask for the door's rough opening size and whether it's single or double before we come out, since that lets us bring the right-width sections and not waste a trip measuring. With 2,614 households in this part of town, we see the same handful of builder-grade door models repeat across streets, which usually makes sizing predictable, but we still confirm on site before cutting anything. If the opening has settled or the framing's out of square - not rare in a house pushing 25 years old - that gets caught at the measure, not after the door shows up.
