What Affects the Cost of a Slab Leak Repair?

Slab leak repairs vary more than most plumbing jobs. These are the things that make the biggest difference in what you'll pay.

1. Finding the leak

Before anything can be fixed, the leak has to be confirmed and located with leak detection. Knowing exactly where it is, and whether it's on the hot or cold side, is what lets us recommend the right repair instead of guessing.

2. Reroute or spot repair

A reroute runs a new line through the walls or attic and takes the leaking section out of service. A spot repair opens the floor at the leak. Which one costs less depends on where the leak is, what's on the floor above it (tile, hardwood, cabinets), and the condition of the rest of the pipe.

3. How far the new line has to run

A short reroute to one bathroom is a smaller job than a long run across the house to the kitchen. More pipe and more wall openings mean more time.

4. Access and patching

Most reroutes need a few small openings in drywall. We keep them as small as possible and leave them ready for patching. Attic access, ceiling height and how many walls the line has to pass through all affect the work.

5. One leak or a pattern

If your home has had more than one slab leak, the pipe under the slab may be wearing out everywhere. Sometimes repiping is the better long-term value than paying for one leak after another. We'll give you both options when it makes sense.
