Foundation repair, concrete repair and crawl space repair in Rancho Palos Verdes, CA

The survey inside the city limits reads as urban fill rather than a natural series, which is normal for ground this built up, so the honest figure is the county one: across Los Angeles County the USDA survey is Millsholm family at about 9 percent of the survey, with Trigo family and Rock outcrop alongside it. Broken down by texture it is 14 percent clay and 16 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 2.58 percent here, which USDA reads as low shrink swell potential. 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 1960s, 6,616 homes, around a median build year of 1967. 14,322 of those homes predate 1980, which is where we most often find footing drains that were never installed and backfill that was never compacted. 17 percent of the housing here, 2,593 units, sits in buildings of five or more, so a fair share of local work is on shared structures rather than single family homes. 66 percent of owner occupied homes here carry a mortgage, which is usually why a lender or an appraiser is the first to ask about a crack. Every evaluation ends with a written estimate that describes what we found at that house.
