Slab Water Leak Detection in Mauldin, SC Reveals Hidden Damage

When a homeowner in Mauldin, SC, noticed unusually high water bills and unexplained moisture near the base of their home, they called in the team at CB Smith Plumbing. Our specialists arrived on-site and quickly confirmed what the homeowner suspected: a hidden slab leak beneath the foundation. With our proven slab water leak detection methods and years of experience, we located the leak without tearing up the home.

This project is a great example of how professional leak detection and repair can save time, money, and major structural headaches for homeowners dealing with mysterious plumbing issues.

Slab leaks are notoriously difficult to spot without proper tools and training. In this case, the homeowner had no visible pipe bursts—just a persistent rise in water bills and soft spots along their flooring. Using acoustic detection equipment and thermal imaging, we were able to isolate the exact point of the leak without causing unnecessary damage.

The cause? A corroded copper pipe running beneath the concrete slab had ruptured due to shifting soil and age. Left unchecked, this could have led to major structural damage and thousands of dollars in repair costs.

Once the leak was pinpointed, we discussed the best course of action with the homeowner. Our licensed technicians performed a localized excavation and pipe replacement—minimizing disruption to the home and restoring water flow with minimal downtime.

In total, the repair was completed in less than two days. We also added pressure regulators and insulation to prevent future leaks in adjacent piping.

While slab leaks are serious, they’re not the only source of rising utility bills or hidden water waste. At CB Smith Plumbing, we advise homeowners to look into:

• Leaky faucets and toilets – A single dripping faucet can waste over 3,000 gallons a year.
• Old water lines – Aging pipes can develop pinhole leaks, especially in copper or galvanized steel systems.
• Outdoor spigots and irrigation leaks – Underground hose bibs often go unnoticed and leak for months.
• Water heater leaks – Minor tank or valve issues can quietly waste hundreds of gallons each month.

Staying proactive with regular plumbing inspections and addressing even small leaks quickly can add value to your home and significantly reduce monthly utility costs.
