If your home sits on a raised foundation, there is a crawl space under your floors, a low area between the ground and the framing where wood posts, concrete piers, and girder beams carry the weight of the house. Serving Long Beach and the surrounding Los Angeles County.
A local specialist will evaluate your foundation, walk you through the findings, and send a clear estimate. No cost, no pressure.

Crawl Space Repair in Long Beach
Long Beach sits in Los Angeles County, California. Roughly 170,174 households sit here, home to about 462,293 people. Detached single family houses number 73,092, and 41 percent of occupied homes are owner occupied.
The crew that covers Long Beach works out of our Irvine office, 27 miles away, about 35 minutes on the road. Los Angeles County carries 1,726,365 detached single family homes in total, 46 percent owner occupied. That is about 5 percent of every housing unit in Los Angeles County. Los Angeles County holds about 9,848,406 people and 3,624,084 housing units in total. Building peaked in the 1950s at 36,729 homes, which is why the median year built sits at 1958. The survey reports a median home value of $709,700 and a median household income of $78,995. Owners hold 69,167 of the occupied homes, renters the other 101,007. 144,431 of those homes were finished before 1980, 85 percent of everything standing.

What we fix
A low shrink swell rating on rock across Los Angeles County means seasonal swelling is not the story. What moves a foundation on ground like this is loading, drainage and the first time a dry layer gets properly wet.
What this looks likeThe pre 1980 stock in Long Beach runs to 144,431 homes, which is where we most often find drainage that was never engineered.
What this looks likeThe typical Long Beach house dates to 1958, old enough that the ground under it has been through every wet spring and dry summer since.
What this looks likeLocal conditions
A city level sample here returns urban fill, not a natural series. Widen it to Los Angeles County and the USDA survey reads Millsholm family at about 9 percent of the survey, with Trigo family and Rock outcrop alongside it. Broken down by texture it is 14 percent clay and 16 percent sand. The weighted linear extensibility figure, which is how much the soil changes volume between wet and dry, sits at 2.58 percent, a low shrink swell rating.
Most of what we walk into here was built in the 1950s, 36,729 homes, around a median build year of 1958. Pre 1980 construction accounts for 144,431 homes here, and that is the group where original drainage is usually the story. 42 percent of the housing here, 71,891 units, sits in buildings of five or more, so a fair share of local work is on shared structures rather than single family homes. 72 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.

"Across Los Angeles County the mapped soil is rock, rated low for shrink swell. Crawl space repair here is not generic. It has to match what the ground is doing."
Our approach
When that system weakens, you feel it upstairs: floors that sag or bounce, doors that stop latching, a musty smell that never quite airs out. The cause is almost always one of two things. Moisture gets in through poor drainage or grading and rots the wood supports, or the clay soil under the piers moves, because clay acts like a sponge, swelling when wet and shrinking when dry, and the supports ride that movement until they lean or sink.
Dalinghaus Foundation Repair's crawl space repair solutions address the whole system, not just the symptom. Depending on what the evaluation finds, that can mean replacing rotted posts and pads, installing steel crawl space jacks to lift and level sagging girders, repairing stem walls, correcting the drainage that let water in, improving ventilation, adding root barriers, or seismic retrofitting that ties the structure to its foundation. The work happens inside the crawl space, so most repairs cause little disruption to your household, and many are finished quickly once the plan is set.
It starts with a free evaluation: a specialist enters the crawl space, documents the supports and moisture conditions, measures your floor elevations, and gives you the findings in writing whether or not you hire us. Since brothers Brian and Brad Dalinghaus founded the company in 2011, we have completed more than 2,000 projects across California, Arizona, and Nevada, and crawl space repair has been core work the entire time. If your crawl space shows these warning signs, schedule your free evaluation.

Dalinghaus was hired to stabilize 4 tilt up panels that were sinking. They did a great job! The poly injection was clean and exactly as described.
Dillion and Julian did an amazing job on my foundation. They are very professional and answered all my questions and made adjustments as requested.
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.
