Crawl spaces are often easily damaged when they settle due to sinking columns and sagging crawl space beams. These problems are caused when foundation soils begin to shift and settle as the soil dries out and shrinks and moistens and swells. Additionally, improperly-spaced beams often become overloaded, causing them, and the floor boards they support, to sag under their burden. Compounding these problems are the mold and rot that can often form in a damp, humid crawl space. Additional Information: Crack Repair Specialists.
