Causes of Sagging Beams or Floor Joists in a Crawl Space

Improperly spaced supports using shims to support sagging floorShifting foundation soils, excessive moisture, or improperly spaced support columns cause structural weakness in floor joists and beams. These conditions are evident in cracks above doors, uneven floors and cracked walls.

Doors that stick, uneven floors and cracked walls also indicate settling. Structural problems, such as settling columns or sagging beams and floor joists, are common within a crawl space. Settling of columns in a crawl spaces are most often caused by weak foundation soils. Over time, these soils shift and settle with changes in moisture content and density, causing movement of the columns and the beams above. Sagging beams and floor joists are often the result of improper spacing of existing pier columns, effectively overloading beams and causing them to bend and sag. Excess moisture and wood rot can also cause beams and joists to weaken over time.
