How to fix uneven floors in house.

Even if you re dealing with uneven floors in an old house steadying the foundation should be a top priority. You can sandwich the framing on either side with plywood. Concrete floors can also lift or sink if the soil underneath them shrinks settles or washes away. 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. A jes foundation repair consultant can perform an inspection and let you know what s causing your sinking floor. 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. If you need to fix sagging floors there are a variety of things you can do.

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. You can strengthen or repair existing framing members by adding reinforcing material. 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. As the posts slowly rot and melt into the floor the house settles accordingly bottom to top.

If the uneven floor is due to floor joists that have warped or twisted over time or were incorrectly installed the only way to level the floor is to remove the subflooring and shim the joists. Compound can correct sags and dips as deep as 1 1 2 inches.
