A Lakewood Dallas home had some flooding from a defective hot water heater. Several rooms and types of materials were damaged. Some of the telltale signs are buckling/warping of hardwood flooring, noticeable separation at the seams often where caulking was applied, swelled particle board usually found in baseboards or cabinetry, and cracked drywall where 2 sheets of drywall come together. These are indications that you most likely have water damage and a water damage mitigation company should be called!
