Signs that warrant a slab-leak assessment
Unexplained water use, damp or warm flooring and running-water sounds when fixtures are off are useful observations. Let us know where each sign appears and when you first noticed it. If the condition is changing, describe that progression and any recent plumbing work.
Cracks, odors or staining can have causes other than a leaking pipe. They should be reported without assuming they confirm water under the slab. The purpose of the inspection is to investigate the plumbing, identify what can be established and explain whether a leak is present.
