Electronic Slab Leak Detection in Durham
Locating a hidden slab leak requires specialized tools. Our plumbers use sensitive electronic listening devices and thermal imaging cameras to pinpoint the exact location of the leak under your concrete foundation. This precision detection reduces the need for extensive concrete removal, saving you time and money. We can detect leaks in both hot and cold water lines, as well as sewer lines, for a complete diagnosis of your Durham home.

Tunneling Slab Leak Repair in Durham, NH
In some cases, especially when the leak is under a load-bearing wall or in a difficult-to-access area, tunneling beneath the foundation is the preferred method. This allows our plumbers to reach the damaged pipe from outside your home, avoiding disruption to your interior floors and finishes. Tunneling spares the interior but requires skilled excavation and shoring to protect structural integrity throughout the repair process in Durham, NH.
PEX Repiping for Slab Leaks in Durham, NH
If multiple slab leaks indicate a systemic issue with your home's original plumbing, a full PEX repipe might be the most cost-effective and durable solution. PEX tubing is flexible, corrosion-resistant, and less prone to leaks caused by foundation shifts, making it a good choice for many homes. We can replace all the water supply lines in your Durham home, providing a brand-new, leak-free plumbing system that will last for decades.
Emergency Slab Leak Repair in Durham, NH
A large slab leak can push water up through flooring or into walls quickly. We help you shut off the water and send a technician to isolate the leaking line. Often we can restore water to the rest of the house while we plan the repair. Quick action limits flooring damage and soil saturation.

Homeowners in Durham trust FVR Plumbing for all their residential slab leak repair needs. We understand the challenges of repairing plumbing under occupied homes, and we work to minimize disruption to your daily life.

Slab Leak Pipe Rerouting in Durham
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 Durham with aging copper or galvanized pipes.
Sewer Line Slab Leak Repair in Durham, NH
Slab leaks aren't always about clean water pipes, since sewer lines can also leak under your foundation. These leaks pose significant health risks and can cause extensive damage. We specialize in detecting and repairing sewer line slab leaks, using camera inspections to identify the exact problem area. Our methods restore proper waste removal and prevent contamination in your Durham, NH property, following health and safety codes.

Cold Water Slab Leak Repair in Durham
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.

Older homes frequently show generations of patchwork plumbing, so repiping can make more sense than repairing one section at a time. When water lines run under the concrete, water chemistry, heat and shifting soil can make slab leaks one of the more common plumbing repairs in Durham, NH.
