What uneven floors usually mean and how they're fixed
A marble that rolls across the kitchen, furniture that rocks, or a floor that feels like walking downhill are among the most common reasons Tulsa homeowners call a foundation pro.
Measure it first
Lay a 4-foot level in several spots, or use a free phone level app along hallways. Note which direction things slope and whether it's concentrated in one area. Some slope is normal in older homes; a professional elevation survey will tell you how much is excessive.
Common causes on slab homes
- A settling corner or wall (perimeter footing sinking into shrinking clay)
- Heave in the middle of the slab from moisture under the house, often a plumbing leak
- Voids under the slab from washout
Common causes on pier-and-beam homes
- Compressed or rotted shims
- Interior piers settling on shallow pads
- Sagging beams or joists, sometimes from moisture or termite damage
Typical fixes
Settling slabs usually need exterior piers. Heave needs the moisture source found and fixed first; piers can make heave worse. Pier-and-beam floors are usually re-shimmed, supported with added piers, or repaired at the beam level.

Frequently Asked Questions
How much slope is too much?
Many engineers look at deflection across the length of the home rather than a single number; differences of more than about 1 to 1.5 inches over 20 feet often get attention. Ask for an elevation survey.
Can sloping floors be fixed without lifting the house?
Sometimes floors can be shimmed or self-leveled cosmetically, but if the foundation is still moving, the slope will return.
