What Moves the Number

No prices here. What makes a slab leak job expensive is access, depth and what is sitting above the pipe.

In one paragraph

Four things move a slab leak quote: whether the leak was located before anyone cut, which repair route is chosen, what the floor is made of, and who makes it good afterwards. Locating it first is what turns a quote into a set of choices rather than one figure.

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.

No prices here, and why

We are a referral service. We do not do the work, we do not set the prices, and an average for a job that depends on where under your particular house the pipe failed would be a made-up number with a dollar sign in front of it.

The things that move it

  1. Locating versus repairing. Two jobs. Some contractors quote them separately and some fold them together; either is fine as long as you know which you are looking at.
  2. Which repair option. A reroute and a spot repair are different work with different disruption.
  3. What is being restored. Concrete only, or concrete and the floor covering over it. This is the commonest late disagreement.
  4. Access. A kitchen island over the leak is a different proposition from an open floor.
  5. Whether the slab can be cut at all, and what establishing that involves.

Two questions worth asking every time

What did the isolation test show — hot or cold? It takes minutes with the water heater valve, and it should already have been done.

What happens if the location is wrong? Settle it before the first cut, not after.

If the meter moved with everything off, you have a leak.That is the finding worth leading with, because it saves an hour of diagnosis. We connect you with a contractor who covers your area, and your ZIP code is what decides who that is. You are never charged. It does not have to be a slab leak either — every kind of plumbing request is routed.
