About Lake Forest

Lake Forest in numbers

Lake Forest is a Orange County town in California. Lake Forest counts roughly 30,298 households and about 85,583 residents. 70 percent of occupied homes are owner occupied, and 17,119 of them are detached single family houses.

Jobs run out of the Irvine office, 4 miles up the road and about 10 minutes out. Across Orange County as a whole there are 563,953 detached single family homes, and 56 percent of occupied housing is owner occupied. Those households are roughly 3 percent of the Orange County total. Orange County holds about 3,164,063 people and 1,138,473 housing units in total. 9,539 homes went up in the 1970s, more than in any other decade, and the median build year is 1984. The Census puts Lake Forest at a median home value of $836,800 and a median household income of $128,358. The split is 21,300 owner occupied to 8,998 rented. Homes built before 1980 make up 41 percent of the stock, 12,428 in all.

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

Local conditions

Why foundations move in Lake Forest

Ground conditions

The mapped soil in Lake Forest is Corralitos at about 40 percent of the survey, with Cieneba and Myford alongside it. The texture split is 40 percent clay and 40 percent sand. Weighted linear extensibility runs 3.04 percent, which is the figure USDA turns into a moderate shrink swell rating.

The age of the housing

The 1970s put up more homes than any other decade, 9,539 of them, and the median year built is 1984. Pre 1980 construction accounts for 12,428 homes here, and that is the group where original drainage is usually the story. 19 percent of the housing here, 5,834 units, sits in buildings of five or more, so a fair share of local work is on shared structures rather than single family homes. 75 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!!

I had Dalinghaus Construction out for a free consultation to check out some cracks in my ceiling, which I feared were based on foundation issues. Tom came from California and was so thorough in examining everything, testing the level of the floor throughout the house, walking the perimeter, and checking for other symptoms. Luckily, it wasn’t a foundation issue. Even though it was a free consultation, I felt like I should pay because he was so thorough. It made me realize how much integrity this company has. I highly recommend this company as trusted professionals that have the competence and integrity to get the job done correctly. I hope I never have foundation issues, but I certainly know who to call if I do!
