Water damage in a brand new construction house
Major plumbing leaks in newly built homes require immediate, thorough drying to prevent hidden moisture from causing long-term mold growth, cracking, and cosmetic staining. Dealing with these sudden issues often forces homeowners to rip out newly installed drywall and structural elements right after moving in, raising intense concerns about proper repairs.
