About Whittier

How Whittier is built

Whittier lies inside Los Angeles County in California. Census figures put the town at about 86,459 residents and 27,489 households. Owners occupy 57 percent of the housing here, and 18,619 homes are detached single family.

Work here is served from the Irvine office, about 35 minutes away at 29 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. Los Angeles County holds about 9,848,406 people and 3,624,084 housing units in total. Half the housing predates 1956, and the 1950s were the busiest building years at 11,047 homes. A median home value of $707,700 and a median household income of $89,686 is what the American Community Survey records. 15,599 of those homes are lived in by their owners and 11,890 are rented. Roughly 93 percent of the housing here, 25,617 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 Whittier

The soil this town is built on

Soil mapping within Whittier returns Zaca across about 40 percent of the survey. Broken down by texture it is 40 percent clay. Weighted linear extensibility runs 9.4 percent, which is the figure USDA turns into a very high shrink swell rating. Clay content is 40 percent inside the city and 14 percent countywide.

The age of the housing

Most of what we walk into here was built in the 1950s, 11,047 homes, around a median build year of 1956. The 25,617 homes finished before 1980 are the ones where drainage was rarely engineered and backfill was rarely compacted. 23 percent of the housing here, 6,233 units, sits in buildings of five or more, so a fair share of local work is on shared structures rather than single family homes. 73 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.

What California customers say

Brian came out for a free consultation to see if our house had foundation issues. We were getting some cracking in our drywall and wanted to know if it was a settlement issue. Brian measured the various elevations in our house, both inside and outside. He also went down in the crawlspace to observe the foundation. He determined our house did not have a major settling issue. He was knowledgeable about expansive soil and we were able to pick his brain about the kind of soil our house was built on. He talked through potential soil strengthening solutions with us, but didn’t recommend any major work be done at the moment. This company has serious integrity- they come out for free, and then determine they are not needed for further work. I will be recommending them to friends who may have foundation issues!!

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
A property I manage had some minor cement work needed to be done. The crew, Dillon & Lance were working on the property. They were quick, efficient, and went above and beyond on the job. The whole process was smooth and easy from getting an estimate to scheduling work and on time. Would recommend highly.
