Sampled inside the Oro Valley city limits, the USDA survey reads Pinaleno at about 40 percent of the survey, with Palos Verdes and Arizo alongside it. The texture split is 40 percent clay and 60 percent sand. Linear extensibility, the measure of how much a soil swells when it takes on water and shrinks when it dries, is weighted at 3.9 percent here, which USDA reads as moderate shrink swell potential. Against 25 percent clay across Pima County, the city sample reads 40 percent. What is actually happening at your address is something we confirm on site, not something we read off a map.

Most of what we walk into here was built in the 1990s, 9,653 homes, around a median build year of 1996. The 2,608 homes finished before 1980 are the ones where drainage was rarely engineered and backfill was rarely compacted. 19 percent of the housing here, 3,957 units, sits in buildings of five or more, so a fair share of local work is on shared structures rather than single family homes. Of the owner occupied homes, 58 percent carry a mortgage. Every evaluation ends with a written estimate that describes what we found at that house.

All of them. Rancho Vistoso, Stone Canyon, Sun City, Canada Hills Golf Course, Linda Vista Citrus and Monterra Estates are all inside the city limits, and every address inside those limits is worked by the same crew on the same terms.

The city covers ZIP codes 85619, 85704, 85737, 85742, 85755. Addresses just outside those boundaries are covered too; a city limit is a mapping line, not a service boundary.
