Peeling or bubbling paint or wallpaper are some of the first signs of water damage on the surface. These symptoms often worsen over time, causing the paint or wallpaper to bloat or warp, resulting in an unsightly appearance.nnWalls and ceilings may even feel spongy to the touch, indicating significant water damage that could compromise the integrity of the structure. Wet flooring is another issue that can go unnoticed, particularly if the moisture is confined to corners or infrequently used rooms.
