What's under Norman homes
Norman sits on a mix of soils (Kirkland, Renfrow, Gracemore, Grant) with a moderate average shrink-swell rating (LEP 4.3), and about 30% of the land under its homes is rated high. That means some streets move a lot more than others. Clay pockets swell after heavy rain and shrink in drought, which is when cracks and sticking doors tend to show up.
Most homes here are newer (median year built 1974 to 1992) and most are likely slab-on-grade. Newer doesn't mean safe on clay: slab movement often shows up in the first decade, especially after a drought year like 2026.
Earthquakes come up a lot here too. The strongest within 25 km of 73069 since 2000 was a magnitude 4.4 (8 km NE of Noble, Oklahoma, 2010-10-13). Quakes that size can crack plaster and brick, but most foundation movement in the metro traces to clay and moisture. How to tell the difference.

Signs worth a look in Norman
Cracks that grow
Diagonal cracks from door and window corners, stair-step cracks in brick, or any crack wider than a coin's edge.
Doors and windows
Sticking, not latching, or gaps opening at the top of the frame, especially after a dry summer.
Floors
A marble that rolls, a bouncy spot, or a slope you can feel. In older homes, check near the middle of the house.
How the free inspection works
- Tell us what you're seeing. Two minutes online, a call, or a text with a photo.
- A local specialist comes out. They check floor levels, walk the outside, look at cracks, drainage and the crawl space if you have one. Usually under an hour.
- You get a straight answer. What's causing it, whether it needs fixing now, and a written estimate if it does. Then you decide. No pressure.
What it might cost
Repair cost mostly comes down to how many piers your home needs and what type. Try the estimator for a ballpark, then get a written number after the inspection.
Ballpark estimator
What might my repair cost?
Ranges are built from published industry figures (Perma-Pier's repair tiers, Modernize's pier-and-beam range, Olshan's national average) and adjusted for home size. They are not quotes. Your real number comes from a written estimate after someone measures your home.
