About Ontario
What Ontario looks like from the truck
Ontario lies inside San Bernardino County in California. Census figures put the town at about 176,326 residents and 51,760 households. The town runs 56 percent owner occupied, with 31,016 detached single family homes in the mix.
Work here is served from the Lake Elsinore office, about 35 minutes away at 29 miles. San Bernardino County carries 516,095 detached single family homes in total, 62 percent owner occupied. This town accounts for about 7 percent of the county's housing. The county around it counts about 2,187,816 residents across 738,535 housing units. Half the housing predates 1979, and the 1980s were the busiest building years at 11,419 homes. A median home value of $513,000 and a median household income of $78,070 is what the American Community Survey records. The split is 28,810 owner occupied to 22,950 rented. Roughly 54 percent of the housing here, 28,171 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.
What we fix
Foundation problems we see in Ontario
Sticking Doors and Windows
Ground under Ontario is mapped sand, with a low shrink swell rating. Soil like that tends to compress rather than swell, which is why what we find here is usually settlement rather than heave.
What this looks likeCracked Bricks
The pre 1980 stock in Ontario runs to 28,171 homes, which is where we most often find drainage that was never engineered.
What this looks likeRaised Foundation Settlement
The typical Ontario house dates to 1979, old enough that the ground under it has been through every wet spring and dry summer since.

The soil this town is built on
Soil mapping within Ontario returns Delhi at about 60 percent of the survey, with Tujunga alongside it. By texture that survey runs 100 percent sand. The weighted linear extensibility figure, which is how much the soil changes volume between wet and dry, sits at 1.5 percent, a low shrink swell rating.
The housing stock
Most of what we walk into here was built in the 1980s, 11,419 homes, around a median build year of 1979. The 28,171 homes finished before 1980 are the ones where drainage was rarely engineered and backfill was rarely compacted. 22 percent of the housing here, 11,193 units, sits in buildings of five or more, so a fair share of local work is on shared structures rather than single family homes. Of the owner occupied homes, 73 percent carry a mortgage.

What California customers say
I cannot say enough good things about this company. Joe, Mike and Manny were easy to work with and friendly. They showed me what they were going to do and left my home clean. I would absolutely recommend this company and in particular these three men to do a job for you. You won’t be disappointed!
They did a fantastic job securing the corner of our townhome that sits about 8’ from a slope. They were professional, friendly, on time and extremely accommodating. Our team was Joe, Manny, and Jose Garcia. The office was awesome as well.Thank you to you all.
Had concerns with my foundation so I called Dalinghaus who scheduled and came out quickly. Mark was my rep and he was wonderful! I highly recommend Dalinghaus and will continue to use them for myself / clients in the future
