About Downey

A closer look at Downey

Downey lies inside Los Angeles County in California. Roughly 34,788 households sit here, home to about 113,052 people. The town runs 49 percent owner occupied, with 20,200 detached single family homes in the mix.

Work here is served from the Irvine office, about 40 minutes away at 31 miles. Countywide, Los Angeles County holds 1,726,365 detached single family homes and runs 46 percent owner occupied. Those households are roughly 1 percent of the Los Angeles County total. The county around it counts about 9,848,406 residents across 3,624,084 housing units. Half the housing predates 1959, and the 1950s were the busiest building years at 14,359 homes. A median home value of $679,000 and a median household income of $84,236 is what the American Community Survey records. The split is 17,201 owner occupied to 17,587 rented. Roughly 87 percent of the housing here, 30,326 homes, went up before 1980, when footing drains and grade separations were not what they are now.

Population and housing figures: American Community Survey, by way of the Signature Media market data set.

Local conditions

Why foundations move in Downey

The soil this town is built on

Mapped soil inside Downey is recorded as disturbed urban ground, so the useful reading is the wider 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. By texture that survey runs 14 percent clay and 16 percent sand. Weighted linear extensibility runs 2.58 percent, which is the figure USDA turns into a low shrink swell rating.

What these homes were built like

Most of what we walk into here was built in the 1950s, 14,359 homes, around a median build year of 1959. 30,326 of those homes predate 1980, which is where we most often find footing drains that were never installed and backfill that was never compacted. 32 percent of the housing here, 11,082 units, sits in buildings of five or more, so a fair share of local work is on shared structures rather than single family homes. 69 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.

We couldn't be happier with the results !if you're looking for a trustworthy construction company, this is the one to call.
JoseJuly 2026via Google
Matt and Dillon and the whole Dalinghaus crew did a fantastic job on my foundation. They went above and beyond, putting long hours everyday. The superintendent James is a foundation magician. When I left my house on Labor Day of 2023, I never thought I would be able to return to my home again. Thank you Dalinghaus for giving my home back to me!
NikkiMay 2026via Google
I had some concerns on my foundation I gave Dalinghaus a call and they sent a sales rep right away he gave me some input on what needed to be done but as for now that we should keep a eye on any more movement and if it proceeds to give another call definitely good customer service !
