The short answer

In Silver Spring, 42% 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.

42% of the housing in Silver Spring is detached houses, which is the kind of building a slab leak happens under.

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.

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.

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.
