Emergency Slab Leak Repair in Dover, NH
A major 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. Fast action limits flooring damage and soil saturation.

Slab Leak Repair Cost Comparison in Dover, NH
Spot repairs usually have a lower upfront cost but involve breaking concrete and repairing flooring. Reroutes cost somewhat more but avoid concrete work and future leaks in that line.

Slab Leak Repair for PEX and Copper Lines in Dover, NH
Whether your home in Dover, NH 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. We carry a full range of parts and tools for both materials, ensuring a correct and durable repair no matter your pipe type.
Slab Leak Detection in Dover
We start by shutting off fixtures and watching the meter to verify a leak. Then we isolate the hot and cold lines to determine which one is leaking. Using acoustic ground microphones, we listen for the sound of escaping water through the concrete. Thermal imaging shows hot water leaks as warm areas on the floor surface.

We know the challenges of repairing plumbing under occupied homes, and we strive to minimize disruption to your daily life.

Slab Leak Pipe Rerouting in Dover
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 Dover with aging copper or galvanized pipes.
Advanced Leak Detection Technology in Dover
Our commitment 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 allows us to locate leaks without guesswork, even in the varied mix of buildings across Dover.

Slab Leak Reroute in Dover
Rerouting is often the best long-term choice, especially with older copper lines. We abandon the leaking line under the slab and run a new PEX line through the attic and walls. Openings are small and placed where patching is simplest. Reroutes end future leaks in that section of pipe.
