What this site is
UnderSlab is a referral service, not a contractor. We connect homeowners with independent contractors. Contractors are required to hold whatever credential their state or municipality demands, and work that opens a structural slab is normally permitted — ask to see the permit. We carry out no work and no leak detection, we do not set prices, and we never charge homeowners anything — the contractors in our network pay us when we route them a call.San Marcos in numbers

What a reading cannot tell you
A meter that keeps moving with the house shut off proves a leak exists. It does not prove where, and it does not prove it is under the slab.
Is it a slab leak
A warm patch on the floor, a sound of running water with every tap closed, and a bill that climbs with nothing damp indoors are the three that point under the slab. Damp on a wall usually points somewhere else.
