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 New York
New York issues no state plumbing license. New York City licenses Master and Journeyman Plumbers through the Department of Buildings; elsewhere in the state it is your own city, town or county. Start here. Ask the contractor which municipality licenses them and confirm it with that office before work begins.

What that coverage looks like
We cover 1,215 ZIP codes in New York across 35 counties, New York County accounting for 149 of them. What is under the floor varies with all of that: a slab in one county and a basement in the next, and the same symptom means a different job in each.
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.
Every New York city we route in
225 cities, ordered by the share of housing that is detached houses. Slab construction and building density move together, and a slab is what makes a leak expensive. Each page carries that city’s own numbers and the ZIP codes we route there.

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.
