Uneven floors in a house are usually a sign of a foundation problem, but not always.
In some cases, a slight slope may be normal and not cause for concern. However, if the slope is severe or getting worse over time, it could be a sign of a serious problem that requires immediate attention. One potential risk of sloping floors is damage to the structural integrity of the home.
The degree to which your floor slopes or sags indicates whether or not you have reason for concern. Typically, floors that slope 1-1/2 inches or less in 20 feet is not a problem. Floors that sag 2 inches or more in 20 feet, though, are a cause for concern.
The typical costs for repairing sagging floors start at $1000 and can go up to $10,000, with the average rate being around $300 per square foot. But this can vary depending on the extent of the damage and materials needed to get the job done.
The first step in fixing uneven floors caused by foundation issues is to address the foundation problem itself.

Many homes older than 15 years tend to experience some sort of foundation issue or settlement. Slab, basement, and crawl space foundations are all at risk of settlement, which can cause your floors to warp, bend, and become uneven.
For homes where this is the case, the subfloors likely need to be replaced. According to Angi and HomeAdvisor, the cost to replace a subfloor ranges from $428 to $2,978, with a national average of $572.

If the damage is caused by flooding or an earthquake, you'll typically require separate coverage.
Leveling floor joists usually means the repair could be as simple as sistering the joists. As mentioned above, the cost to sister floor joists runs approximately $100 to $300 per joist. In other cases, the shims may need replacing, or the supporting structure could be rotting, which is a much bigger job.
