Sherman Hill is the oldest residential neighborhood in the city, on the National Register of Historic Places since 1979 — Victorian-era homes and early apartment buildings with the period details to match. Beaverdale, over by Drake and Waveland Park, is mostly 1920s-40s bungalows, Tudors, and Colonials. Waterbury, south of Grand, tends toward larger, well-kept older homes under a real tree canopy. Three neighborhoods, three different centuries of construction, three different sets of problems once you open up a wall.
That's the thing about remodeling in Des Moines proper that doesn't apply in most of the smaller towns around it: there's no single "typical house" to plan around. A kitchen remodel in a Sherman Hill Victorian and a kitchen remodel in a Beaverdale bungalow are not the same project, even if the homeowner's wish list looks identical on paper.
Tell us the neighborhood, and we'll already have a decent guess at what we're walking into.
