How to fix uneven floors in house.

If you need to fix sagging floors there are a variety of things you can do. Lay a long level downhill on the floor with one end of the level on the level part of the floor and the other end at the lowest point. Compound can correct sags and dips as deep as 1 1 2 inches. As the posts slowly rot and melt into the floor the house settles accordingly bottom to top.

If your foundation is settling it may be lifting your concrete floor as it moves. Raise the lower end of the level until the bubble is centered then measure the distance from the bottom of the level to the floor to find the depth of the dip. Even if you re dealing with uneven floors in an old house steadying the foundation should be a top priority. You can try reinforcing metal but this depends on the conditions you re encountering.

Since masonry is more likely to break than bend concrete floors that are uneven are generally cracked or broken as well. If your house is built over a basement first inspect all of the basement support beams and posts where they meet the floor. You can sandwich the framing on either side with plywood. If you have access to the basement or crawlspace it is possible to jack up saggy joists until they are level and then sister them so that they remain straight after the jacks are removed.

You can strengthen or repair existing framing members by adding reinforcing material. Concrete floors can also lift or sink if the soil underneath them shrinks settles or washes away.
