When to get a foundation looked at
Some situations make the decision easy. A crack that has grown, a wall that looks like it is leaning, or water showing up somewhere it never did before are all reasons to have someone out soon.
Other situations are less urgent but still worth acting on. Doors and windows that stick or no longer close squarely can point to foundation movement, though they can also have other causes. Floors that slope noticeably, gaps appearing between walls and ceilings, or a basement that smells musty after dry weather are all things worth mentioning to a professional.
If you are buying or selling a home, a foundation review gives you information before you commit. If you are in an older Omaha neighborhood, it is worth knowing that Dundee dates to the late 1880s, Field Club's main building boom ran from about 1910 into the early 1920s, and Minne Lusa was platted in 1916. Foundations in those neighborhoods have had a long time to move.
What causes foundation issues in Omaha
Omaha sits on loess, a fine wind-blown silt, with clay-rich subsoils that move with moisture. The city engineer has noted that loess can be easily carried away by water, leaving behind gaps underground. When the soil beneath or around a foundation shifts, settles, or erodes, the structure above it responds.
Omaha's climate adds to that. The city averages about 135 days a year with a low at or below freezing, and about 31.86 inches of precipitation annually, with May the wettest month. Freeze-thaw cycles move soil repeatedly over the winter, and a very wet spring can saturate the ground and change how it supports a foundation. The 1970s were Omaha's biggest home-building decade, which means a large share of the housing stock is now old enough that original waterproofing and drainage systems may be showing their age.
Two kinds of inspection: contractor estimate vs. structural engineer report
This is a distinction worth understanding before you make any calls.
A foundation or waterproofing contractor will typically come out, look at the issue, and give you a free estimate. They are assessing the problem with an eye toward quoting a repair. That is useful and often the right starting point, especially if the issue is visible and the fix is relatively clear.
A licensed structural engineer takes a different approach. They are hired to evaluate and report, not to sell a repair. They will measure, document, and give you a written assessment of what they found and what they recommend. They have nothing to sell you, which can make their opinion easier to weigh. Their visit is not free, but if you are dealing with something serious, buying a home with a questionable foundation, or want a second opinion before committing to a significant repair, an independent engineer's report can be worth the cost.
Both are legitimate options. For a minor crack or a straightforward drainage issue, a contractor's estimate is usually enough. For something that involves significant structural movement or a large investment, having an engineer's report first gives you a clearer picture.
What to expect during a contractor's visit
A contractor will walk the perimeter outside, look at grading and drainage, and then go through the basement or crawl space. They will note cracks, moisture, any signs of movement, and how the walls and floor look at the joints. They should be able to explain what they are seeing and why they are recommending what they recommend.
Ask them to show you the specific areas they are concerned about. Ask what they think caused it. Ask what happens if you wait. A good contractor will answer those questions clearly.
How to choose someone to inspect your foundation
Nebraska requires contractors to register with the Nebraska Department of Labor, and you can search by name, city, or ZIP at dol.nebraska.gov. The state notes that registration does not ensure quality of work, so also check the BBB of the Midwest Plains, which is based in Omaha. Structural repairs usually need a city permit; a good contractor pulls it for you. If you are not sure whether your situation requires one, check with your city.

Frequently asked questions
Should I get a structural engineer or a contractor first?
For most visible issues, starting with a contractor's free estimate is reasonable. If the issue is significant, involves clear structural movement, or you want an independent opinion before a large repair, hiring a structural engineer first gives you an unbiased assessment you can take to any contractor.
Can a foundation inspection find radon problems?
A foundation inspection focuses on structural and water issues. Radon is a separate concern. Douglas County tests have averaged 4.8 pCi/L and Sarpy County 5.3 pCi/L, both above the EPA action level of 4.0. If you have not tested for radon, that is worth doing independently. Nebraska requires radon testers and mitigators to be state licensed.
How often should a foundation be inspected?
There is no fixed schedule, but checking after a very wet spring, after a severe freeze-thaw season, or any time you notice something new is a reasonable habit. Older homes in Omaha's historic neighborhoods are worth keeping an eye on simply because of their age.
