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.El Sobrante in numbers

It is found by listening first
Correlation and acoustic listening locate a leak before anything is opened. Opening the floor to find it, rather than to fix it, is the expensive order to do this in.
Reroute or repair
A single leak in an accessible run can be repaired in place. Where the line has failed once it often fails again, which is why rerouting above the slab is sometimes the better answer over the life of the house.
