Slab Leak Repair in Saint Louis, Missouri 63101
60% of housing is detached houses.
Free to homeowners in Saint Louis — the contractor pays us for the introduction, you never do.
The short answer
In Saint Louis, 60% of housing is detached. A slab leak is located by listening and correlation before any floor is opened, and a meter that moves with the house shut off proves a leak exists but not where it is.
Source: US Census Bureau, American Community Survey, table B25024, five-year estimates. A margin of error is published alongside every estimate.
In Saint Louis, 60% of homes are detached. A leak in a line cast into the slab is a single-family problem almost everywhere.
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.Saint Louis in numbers

Is it a slab leak
A warm patch on the floor, a sound of running water with every tap closed, and a bill that climbs with nothing damp indoors are the three that point under the slab. Damp on a wall usually points somewhere else.
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.

Checking a plumber in Missouri
Missouri has no state plumbing board. Section 341.010 of the Revised Statutes requires a certificate for plumbers working in cities or towns of fifteen thousand or more inhabitants, and the chapter elsewhere recognizes licenses issued by any county or city operating under plumbing rules, so the office that issued one is a local office. Start here. Ask the contractor which municipality licenses them and confirm it with that office before work begins.
