Storm & Flood Damage Recovery in Mesquite, TX

Usually not from water on the floor, which is what makes it different from a supply leak. A drain line is not pressurized, so it leaks only when something is running, and the water goes into the subgrade rather than up through the slab. The signs are indirect: slow fixtures, unexplained settlement, damp smells, or a floor that has begun to move. A camera inspection of the under-slab drains is the way to confirm it, and it is worth doing on a house of this era.

Not automatically, and it is worth knowing its condition. Cast iron of this age in soil that moves seasonally develops cracks and separations, and once one section has failed others usually follow. A camera inspection tells you whether you are looking at one repair or a system at the end of its life. That distinction changes the decision, because tunneling or rerouting is a very different project from a single spot repair.

The plumbing, because a leak invalidates any foundation assessment made while it is running. On this clay, movement breaks lines and leaking lines wet clay and drive more movement, so each can be cause or effect. A pressure test on the supply and a camera on the drains settles it in a day. If both are sound, the water is arriving from outside and the answer is drainage.
