How much does slab leak detection cost?
Slab leak detection is $400–$800. We test and listen to pinpoint the leak before any concrete or wall is opened.
How much does a slab leak reroute cost?
A slab leak reroute starts at $1,875 (posted range $1,875–$2,463).
A reroute means the leaking under-slab line is capped and abandoned, and a new line is run through the attic and ceiling, then down inside a wall to the fixture. Your slab is not broken up.
What is a slab leak reroute?
Instead of jackhammering the floor to reach the pipe, we leave the bad under-slab line in place, cap it, and run a new line overhead through the attic and ceiling.
How much does it cost to repipe a house?
An attic & ceiling repipe starts at $7,663, and whole-home repiping is $8,763.50–$15,764.50 depending on house size and number of fixtures.
What about breaking the slab to fix the pipe directly?
Direct access repair (opening the slab) is quoted in writing before work, because the cost depends on where the leak is and what flooring sits over it.
What if you find extra work on site?
We stop, show you what we found, and give you a written quote. Nothing extra is done until you approve it.
How do I know if I have a slab leak?
Common signs are a warm or damp spot on the floor, the sound of running water with everything off, a high water bill, or a water meter that keeps moving when no water is in use.
