Uneven Floor

Sinking Or Uneven Floors In Your Home

A floor that is sinking by a half inch.

This wood floor in a Milaca home is sinking by 1/2". It's located over a crawl space.

Sinking floors can lead to a variety of other issues, including jamming doors and drywall cracks.

In addition, uneven floors over crawl spaces are often accompanied by serious mold problems.

The Problem:

The floors in your home are significantly out of level.

Telltale Signs:

  • Sinking or Heaving Concrete Slabs
  • A Floor That Sags Toward the Center of the Houses
  • Interior Doors Jamming
  • Floor Cracks
  • Mold & Rot In The Crawl Space

How to Fix It:

If you have a crawl space and the floors above are out of level, you may have a structural problem in your crawl space. Crawl space jacks can address the structural problems.

If a concrete slab is uneven, it could be because of settlement or foundation heaving. Foundation heaving can be a very complicated problem, and a foundation contractor should inspect the problem in person.

Causes & Solutions For Uneven Floors

Uneven floors are rarely caused by problems with the floor system itself. Instead, it's often a settling or shifting foundation issue that has impacted the floor system.

Floor beams and joists are made from wood that will usually bend or flex rather than crack or break. The same can't be said for masonry foundations. When soil issues cause a foundation to break, the floors above usually bend.

Floors Above Crawl Spaces

The floor joists above a typical crawl space are supported by the perimeter walls of the crawl space foundation, and by a post or column-and-beam framework that extends down the center of the crawl space

Although the perimeter walls of a crawl space can settle or shift to cause floor problems above, it's more common for the center support system to settle or sag because it wasn't properly built in the first place.

A center post-and-beam support system can also weaken and settle because moisture in a dirt-floored crawl space has caused wood supports to rot and collapse. As crawl space structures begin to sag, the floor above will sag in turn.

Other symptoms of a sagging crawl space include interior wall cracks, jamming doors, and gaps between walls or doors and the floor underneath them.

The Solution:

At Northern States Basement Systems, we can quickly and effectively repair a crawl space structural issue with our heavy duty crawl space jacks. Crawl space jacks are adjustable steel posts that will stabilize sagging crawl space structures.

During installation, we prepare a base of compacted engineered fill at all jack placement points, located directly beneath the main support beam. We install a pre-cast concrete base on this fill, and then extend a crawl space jack between the base and the beam.

Once each jack's threaded rod is adjusted beneath the post, the weight bearing on the beam is transferred to the soil below. Additionally, this system allows the contractor to push a sagging floor back toward its original level position.

Our warrantied crawl space jacks can effectively stabilize your crawl space -- usually in a day.
