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.Checking a credential in Nevada
Nevada licenses are issued by the Nevada State Contractors Board, which publishes a public search you can use before work begins. Nevada licenses the C-1 plumbing and heating contractor classification rather than an individual journeyman.

What that coverage looks like

How a slab leak repair job goes
A slab leak is located first and repaired second, and the second decision is between rerouting the run overhead and breaking the floor to reach it. Rerouting leaves the floor intact and abandons the old line in place; breaking through is the shorter job where the leak is near an edge and the floor covering is replaceable. Both are reasonable; they are not interchangeable.
What the call asks about slab leak repair
- Whether there is a warm patch on the floor, or the sound of water with everything off.
- Whether the meter moves with the house shut off at the main.
- What the floor is — tile, carpet, wood, polished concrete — because it decides the cost of reaching the pipe.

Before you call
A slab leak is either rerouted overhead or reached through the floor, and the choice is made before anything is broken. The pages above set out both.
