Most squeaky floors in Memphis come from friction, not weakness — subfloor panels sliding against nails or joists that have lost their bite. Our loess soil subtly settles after heavy rain, and that movement transfers upward, changing how floor systems bear weight. Add Memphis humidity, and the subfloor absorbs moisture while joists lag behind, creating tiny gaps that squeak when walked on. In multi-story homes, we also see vibration transfer from storm pressure changes that loosen older fasteners over time. Instead of surface fixes, we focus on re-securing the floor system itself using screw patterns and adhesive methods that hold up through Memphis’s wet–dry cycles.
