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 Phoenix and the surrounding Maricopa 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 Phoenix
Phoenix sits in Maricopa County, Arizona. Roughly 591,169 households sit here, home to about 1,609,456 people. Owners occupy 56 percent of the housing here, and 378,891 homes are detached single family.
The office is here rather than an hour away, which is why this is one of our busiest markets. Across Maricopa County as a whole there are 1,189,056 detached single family homes, and 65 percent of occupied housing is owner occupied. Those households are roughly 32 percent of the Maricopa County total. Maricopa County holds about 4,491,987 people and 1,850,862 housing units in total. Building peaked in the 1970s at 123,109 homes, which is why the median year built sits at 1984. The survey reports a median home value of $340,200 and a median household income of $72,092. 333,631 of those homes are lived in by their owners and 257,538 are rented. 276,192 of those homes were finished before 1980, 47 percent of everything standing.

What we fix
A low shrink swell rating on loam under Phoenix 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 like276,192 homes in Phoenix were finished before 1980, back when a footing drain was optional and backfill was rarely compacted.
What this looks likeThe typical Phoenix house dates to 1984, old enough that the ground under it has been through every wet spring and dry summer since.
What this looks likeLocal conditions
The USDA soil survey inside Phoenix comes back Gilman at about 40 percent of the survey, with Laveen and Rock outcrop alongside it. The weighted linear extensibility figure, which is how much the soil changes volume between wet and dry, sits at 1.48 percent, a low shrink swell rating.
The typical house dates to 1984, and the single biggest block of the stock, 123,109 homes, went up in the 1970s. The 276,192 homes finished before 1980 are the ones where drainage was rarely engineered and backfill was rarely compacted. 28 percent of the housing here, 165,517 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.

"Under Phoenix the mapped soil is loam, 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.

I was really stressing about the garage/outside area foundation at my home in North Phoenix, but Jim from Dalinghaus Foundation Repair was awesome and totally put my mind at ease. He did a super thorough job checking out the whole foundation and the exterior of the house. He actually took the time to explain the foundation of my home and answered a ton of my questions without making me feel rushed. The best part? His honesty. There was absolutely zero upselling. Jim actually pointed out an alternative solution that was way more practical and saved me money. It's already hard to trust people/companies, so I really appreciated his approach. If you're in the North Phoenix/Paradise Valley area and need someone who you can actually trust and do the job, definitely give these guys a call and ask for Jim.
Truly the best interaction I've had with a maintenance company since moving to Phoenix in 1989. Their representative, Jim Hughes was phenomenal! He was knowledgeable, professional and kept me informed of the actions being taken as they occurred. He readily answered my questions to ensure my understanding. Service was Better than A+++. I will definitely this company again for any needs I have which they can help with. Kudos to Jim and Dalinghaus for service provided with honesty and integrity!
Jim came out to do the inspection and was very professional, thorough and answered all my questions. Explained the two options, how long it would take and what it would take to do either one. Very satisfied with the inspection.
