Foundation repair, concrete repair and crawl space repair in Chino, CA

Sampled inside the Chino city limits, the USDA survey reads Chino at about 60 percent of the survey, with Hilmar and Chualar alongside it. Broken down by texture it is 80 percent clay and 20 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 3.78 percent here, which USDA reads as moderate shrink swell potential. The sample inside the city runs 80 percent clay against 6 percent across San Bernardino County, so the ground here is heavier than the county average. What is actually happening at your address is something we confirm on site, not something we read off a map.

The typical house dates to 1986, and the single biggest block of the stock, 6,538 homes, went up in the 1970s. 11,201 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, 4,504 units, sits in buildings of five or more, so a fair share of local work is on shared structures rather than single family homes. Mortgages sit on 74 percent of the owner occupied homes in Chino. Every evaluation ends with a written estimate that describes what we found at that house.
