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 Flagstaff and the surrounding Coconino 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 Flagstaff
Coconino County holds Flagstaff, in Arizona. About 76,177 people live here, across roughly 27,062 households. 43 percent of occupied homes are owner occupied, and 13,838 of them are detached single family houses.
Our office is in the town itself, so the crew starts the day here. Coconino County carries 41,433 detached single family homes in total, 59 percent owner occupied. That is about 39 percent of every housing unit in Coconino County. The county around it counts about 144,643 residents across 69,907 housing units. The median home was finished in 1991, with more of the stock built in the 1990s than in any other decade, 6,461 homes. Survey figures show a median home value of $466,600 and a median household income of $65,652. The split is 11,668 owner occupied to 15,394 rented. About 8,847 homes, 33 percent of the stock, predate 1980 and the drainage standards that came with it.

What we fix
Soil sampled inside Flagstaff carries a moderate shrink swell rating, which means it can swell when it is wet and shrink when it dries.
What this looks likeThe pre 1980 stock in Flagstaff runs to 8,847 homes, which is where we most often find drainage that was never engineered.
What this looks likeThe typical Flagstaff house dates to 1991, old enough that the ground under it has been through every wet spring and dry summer since.
What this looks likeLocal conditions
The survey inside the city limits reads as urban fill rather than a natural series, which is normal for ground this built up, so for the soil series the county survey is the reading: across Coconino County the USDA survey is Unnamed soils at about 10 percent of the survey, with Rock outcrop and Winona alongside it. The texture split is 14 percent clay and 22 percent sand. For swelling and shrinking, the city sample is the more specific reading. Inside the Flagstaff city limits it gives a weighted linear extensibility of 5.1 percent, which USDA reads as moderate shrink swell potential. Karst features are mapped in this area, so voids and sinkhole risk are part of the evaluation.
Most of what we walk into here was built in the 1990s, 6,461 homes, around a median build year of 1991. 8,847 of those homes predate 1980, which is where we most often find footing drains that were never installed and backfill that was never compacted. 34 percent of the housing here, 9,307 units, sits in buildings of five or more, so a fair share of local work is on shared structures rather than single family homes. Mortgages sit on 65 percent of the owner occupied homes in Flagstaff.

"Across Coconino County the mapped soil is rock, and the sample inside Flagstaff is rated moderate 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.

Method, scope, and pricing, in writing. Warranty terms for your specific repair are spelled out in the estimate.
A Dalinghaus crew completes the installation with the site left cleaner than we found it.
Every home is different, so every estimate is written for the home in front of us. A free on site evaluation gives you a written estimate that reflects your specific scope, access, and conditions.
Crawl Space Repair pricing varies with depth, load, access, and soil. Typical residential jobs are estimated during the free on-site evaluation, and the written estimate spells out the method, scope and price. If site conditions change the work, the change is written and signed before it goes ahead.
If a home has purely cosmetic cracks with no structural movement, no door or window racking, and no floor slope, we will say so during the evaluation and recommend you wait or address the underlying cause first. If we cannot fix it right, we will not sell you a fix.
