Know the warning signs of a slab leak
Unexpected water use, warm or damp flooring, lower pressure and running-water sounds when fixtures are off can signal a hidden plumbing concern. Cracks, musty odors or unexplained moisture also deserve attention. These signs are reasons to investigate, not a diagnosis of the pipe or foundation.
Make a note of when the change began and which areas are affected. Explain whether moisture is actively spreading or whether the concern comes and goes. That pattern, together with the inspection findings, gives the team a better starting point than guessing where to open a floor.
