Leaks are repaired efficiently using methods designed to address the exact problem while limiting disturbance to your home.

Repairing hidden leaks helps reduce water waste, lower utility bills, and protect your home from escalating damage costs.
Most homes in Jacksonville and the surrounding area are built on a concrete slab, with water lines running under or through the foundation. Over time those buried lines can wear through where they rub against concrete or gravel, corrode, or crack as the ground shifts. Hot water lines are the most common culprit, because heating and cooling makes the pipe expand and contract every day.
Turn off every faucet, appliance and irrigation zone, then look at your water meter. Most meters have a small leak indicator that spins when water is moving. If it keeps turning, or the reading changes after an hour with nothing running, water is escaping somewhere and it is time for professional leak detection.
Finding a leak under concrete is about narrowing it down before anything is opened up. Plumbers typically isolate the hot and cold sides with pressure testing, then use electronic listening equipment, line tracing and thermal imaging to pinpoint where the water is escaping. Accurate location means a smaller opening, less damage to your floors and a faster repair.
Spot repair: a small section of the slab is opened directly over the leak, the damaged pipe is repaired, and the floor is closed back up. This works well when the rest of the line is in good shape.
Reroute: the failing line is abandoned and a new line is run through the walls or attic instead of under the slab. This avoids breaking concrete and is often the better long-term choice when the old line has more than one weak spot.
Repipe: when several leaks have already occurred, replacing the supply lines throughout the house may be the most reliable fix. See our repiping services for more.
A slab leak rarely stops on its own. Water under the foundation can damage flooring, feed mold and, over time, affect the soil that supports the slab.
