Spot Repair Through the Slab in Charleston, SC
When the leak is isolated and the rest of the pipe is in good shape, a spot repair through the slab is a practical option. We cut a small opening, excavate to the pipe and replace the damaged section. The trench is compacted and the concrete is patched. Flooring is then restored by your preferred contractor.

Advanced Leak Detection Technology in Charleston
Our approach to effective slab leak repair includes investing in modern diagnostic technology. We use equipment such as thermal imaging cameras to detect temperature changes caused by leaking hot water lines, and highly sensitive acoustic sensors to listen for the sound of escaping water. This technology lets us locate leaks without guesswork, even in the varied mix of buildings across Charleston.
Slab Leak Pipe Rerouting in Charleston
For more complex or recurring slab leaks, or when the original piping is badly deteriorated, pipe rerouting is an effective long-term solution. This method involves abandoning the leaky pipe under the slab and installing new plumbing lines through walls or the attic, bypassing the foundation entirely. This removes future slab leak risks from that particular line and is often preferred for older homes in Charleston with aging copper or galvanized pipes.
Commercial Slab Leak Repair in Charleston, SC
Businesses in Charleston also face the risk of slab leaks, which can disrupt operations and lead to costly downtime. KBN Plumbing provides complete commercial slab leak repair services, suited to the specific needs of your business. We work quickly to diagnose and fix the problem, so your commercial property in South Carolina can return to normal operations with minimal interruption while staying safe and compliant.
Slab Leak Repair Cost Comparison in Charleston, SC
Spot repairs usually have a lower upfront cost but involve breaking concrete and repairing flooring. Reroutes cost a bit more but avoid concrete work and future leaks in that line. Whole-house repipes are the best choice when you have had multiple slab leaks or old copper throughout. We give you clear prices for each option.
Direct Slab Penetration Repair in Charleston, SC
When a slab leak is directly accessible and localized, direct slab penetration is often the most efficient repair method. This involves carefully cutting a small section of your concrete slab to access and repair or replace the damaged pipe section. Our team makes sure the repair is fully compliant with South Carolina plumbing codes and the slab is correctly restored, preventing future issues. We take great care to contain dust and debris during this process in your Charleston home.
Cold Water Slab Leak Repair in Charleston
Cold water slab leaks are harder to feel but still waste water and wet the soil. They often show up as a high water bill or a meter that moves with all fixtures off. We isolate the cold line, locate the leak and repair or reroute it. Fixing cold leaks promptly helps protect your foundation.

Slab Leak Repair for PEX and Copper Lines in Charleston, SC
Whether your home in Charleston, SC has modern PEX piping or traditional copper lines, our plumbers are skilled in repairing both. Pinhole leaks are common in older copper due to corrosive soil conditions and water chemistry, while PEX can sometimes suffer from installation issues or rodent damage.

The cost of slab leak repair in Charleston, SC can vary widely, usually ranging from $1,000 to $5,000 or more, depending on the leak's location, severity, and chosen repair method.

Look for sudden spikes in your water bill, warm spots on your floor, the sound of running water when no fixtures are in use, visible water stains or mildew on baseboards or carpets, and cracks in your foundation. These are strong indicators that you might have a hidden slab leak in your Charleston home.
While not entirely preventable, regular plumbing inspections can help catch potential issues early. Using quality plumbing materials during construction or repiping, and checking any noticeable water pressure changes promptly, can help reduce the risk of slab leaks in your Charleston home.
Older homes in Charleston with copper or galvanized steel pipes are often more prone to slab leaks due to corrosion and material wear over time. While PEX is more flexible and resistant to corrosion, it can still develop leaks from installation errors, excessive pressure, or physical damage. Our team repairs all common pipe types.
Yes. Water continuously leaking under your foundation can erode the soil, leading to voids and uneven settlement, which can cause cracks in your foundation, walls, and flooring. Clay that swells when wet and shrinks in dry spells can stress buried sewer lines over time, leading to sags, separated joints and root intrusion.
Detection typically takes one to three hours. Spot repairs and reroutes generally take one to two days.
You can check your water meter with all fixtures off and feel floors for warm spots. Finding the exact location requires professional detection equipment.
