The older neighborhoods — around the Santa Fe downtown core, along Metcalf, and the streets off 75th — are 1950s through 1970s ranches and split-levels. Solid oak, nailed down, frequently under carpet. That is refinishing territory, and the same logic applies here as in Prairie Village.
South Overland Park is a different building. The subdivisions that filled in from the 1980s through the 2000s were built with a mix of engineered flooring, builder-grade carpet and, later, luxury vinyl. Engineered floors have a wear layer measured in fractions of a millimeter — some can take one sanding, many can take none at all.
That distinction decides everything about your quote. Sanding an engineered floor with no wear layer left destroys it, and no amount of skill recovers from that. So the first thing we do in a south Overland Park house is identify what is actually on the floor before we talk about price.
