How Does Slab Leak Detection Work?
A slab leak is a supply or drain line failure beneath the concrete slab foundation of your home. In West Columbia, SC, slab leaks often develop in copper pipes installed in the 1960s–1980s that have corroded from soil contact and groundwater. They’re hard to detect — signs are warm spots on the floor, unexplained water bills, the sound of running water with everything off, and wet flooring. Left unaddressed, slab leaks erode the foundation and cause serious structural damage. Merritt Plumbing locates and repairs slab leaks throughout West Columbia using electronic detection equipment to minimize unnecessary concrete cutting. Call (803) 254-7542 for slab leak detection and repair.
What Does Slab Leak Repair Cost in West Columbia, SC?
We use a combination of acoustic listening equipment and thermal imaging to locate the leak point before cutting. Acoustic sensors detect the sound of water escaping under pressure through concrete and soil. Thermal cameras find temperature differentials where warm or cool water is affecting the slab surface. Using both methods, we can pinpoint the leak to within a few inches, which means we cut only the concrete needed — typically a 12-inch to 24-inch area rather than opening a large trench. After locating the leak, we present repair options: spot repair through the slab, pipe rerouting above slab, or pipe lining.
Why Choose Merritt Plumbing for Slab Leak Repair?
Slab leak repair in West Columbia runs $1,500–$5,000 depending on the repair method. Spot repairs through the slab are at the lower end. Above-slab pipe rerouting — running new copper or PEX through the walls and ceiling to bypass the slab section — avoids concrete work entirely and often costs less overall. Pipe lining (epoxy lining of the existing pipe) is an option for drain line slab leaks. We provide written estimates for each option after locating the leak. Most homeowners’ insurance covers slab leak repairs — we provide documentation for the claim. Call (803) 254-7542.

What to Expect During a Slab Leak Repair
Spot repair through the slab works well for a single isolated leak in an otherwise sound pipe. Rerouting — bypassing the slab section with new pipe through walls or attic — is often preferred for older copper that shows widespread corrosion, since another slab leak is likely on the same pipe within a few years. Pipe relining uses epoxy coating blown through the existing pipe to seal leaks from the inside — best for drain lines where excavation is difficult. Merritt Plumbing discusses all three options with West Columbia homeowners and recommends based on your specific pipe condition, not the easiest option for us.
