Overview
Slab Leak Detection and Repair Across Monroe and Ouachita Parish
A sudden spike in your water bill — with no obvious explanation — is one of the most common warning signs of a slab leak. Monroe homes built on concrete slab foundations have water supply lines running beneath or through that concrete, and when one of those pipes develops a leak, the water quietly escapes into the ground or up through the slab. Left unaddressed, a slab leak can undermine your foundation, cause structural damage, and drive up your utility costs month after month.
Slab leaks are among the most frustrating plumbing problems a homeowner faces because the damaged pipe is encased in concrete. Mark Johnson & Sons Plumbing uses accurate electronic detection equipment and pressure testing to pinpoint the leak's exact location before any demolition begins. That precision means less concrete cut, less mess, and a faster repair — protecting both your home and your wallet.
North Louisiana's clay-heavy soil can shift seasonally, putting stress on the copper and galvanized pipes commonly found beneath older Monroe slabs. Our experienced technicians present every available repair option — direct access repair, pipe rerouting, or epoxy lining — with honest upfront pricing so you can make an informed decision. We have been handling slab leaks across Ouachita Parish since 1997.
