What Is a Slab Leak?

A slab leak occurs when water lines located beneath your home’s concrete foundation develop cracks or breaks. These leaks can be caused by shifting soil, corrosion, or high water pressure that weakens the pipes over time. Because they’re hidden underground, slab leaks often go unnoticed until water damage becomes visible inside the home.

Early detection is key to minimizing the impact of a slab leak. Common signs include unexplained water puddles, damp flooring, warm spots on concrete, or a sudden rise in your water bill. Our technicians use specialized equipment to pinpoint the exact location of the leak without unnecessary excavation.

Our Slab Leak & Foundation Leak Repair Services

At Landry Mechanical, we provide complete leak detection and repair services for homes built on slab foundations. Our goal is to locate the problem quickly, repair it efficiently, and restore your plumbing system with minimal disruption to your home.

Leak Detection and Diagnostics

Using advanced equipment such as acoustic sensors and thermal imaging, we can detect leaks hidden under your slab with precision. Our methods eliminate the need for guesswork or excessive digging. Once located, we create a repair plan that addresses the issue directly and prevents it from returning.

Targeted Pipe Repair

When a pipe beneath the foundation is damaged, our team performs localized repairs to stop the leak at its source. We remove only the affected section and replace it with high-quality materials rated for long-term performance. Afterward, we test the system to confirm that the leak has been fully resolved.

Pipe Rerouting and Replacement

In some cases, rerouting or replacing damaged lines is the best long-term solution. Our plumbers design new, efficient routes that bypass the damaged area entirely, restoring water flow and preventing future leaks. Every installation is completed to code and pressure-tested for safety.

Foundation Leak Protection

In addition to repairing the immediate problem, we assess the surrounding area to prevent future damage. Our team checks for signs of soil movement, pipe stress, and excess moisture that could compromise your foundation. With proper prevention, your plumbing system and structure will stay secure for years to come.

Corey Menard is a STELLAR human being as well as an EXPERT HVAC technician! He cheerfully and swiftly diagnosed an in-wall heating pipe burst, repaired it, and added a much-needed shut-off valve for one of my (three) heating zones. My English language dictionary does NOT contain the words I need to express my gratitude toward him, or express my gratitude to Landry for sending Corey to my home on Wednesday 02/11/2026. Thank Corey, thank you, and thank Corey!
