In Lee’s Summit, sagging floors are often linked to moisture issues caused by heavy rainfall, clay-rich soils, and drainage challenges, particularly in neighborhoods near Lake Lotawana, Raintree Lake, and older subdivisions throughout the city. When water seeps into the soil around your foundation, it can saturate the sill plate, floor joists, and wooden beams that support your home. These components sit directly above concrete and exposed soil, making them especially vulnerable to moisture intrusion. As the wood absorbs water, it begins to deteriorate and lose strength. Over time, this deterioration weakens the floor system, leading to uneven or sloping floors inside the home.
