Pipe Rerouting and Repiping in Derry
For more extensive damage, multiple leaks, or pipes that are too old and corroded to repair reliably, pipe rerouting is a long-term solution. This involves abandoning the leaking line under the slab and installing a new pipe through the walls or attic. This method skips the problem area entirely, providing a fresh, durable plumbing line. It is a common solution for aging homes in Derry with original copper or galvanized plumbing.

Slab Leak Repair for PEX and Copper Lines in Derry, NH
Whether your home in Derry, 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, making for a correct and durable repair no matter your pipe type.
Slab Leak Detection in Derry
We start by shutting off fixtures and watching the meter to verify a leak. Then we isolate the hot and cold lines to find out 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.

Sewer Line Slab Leak Repair in Derry, NH
Slab leaks aren't always about clean water pipes, since sewer lines can also leak under your foundation. These leaks pose serious health risks and can cause extensive damage.

Our methods restore proper waste removal and prevent contamination in your Derry, NH property, following health and safety codes.
Direct Slab Leak Repair in Derry, NH

We use durable materials designed to hold up to soil movement under the slab.

Frequently Asked Questions About Slab Leak Repair in Derry
The cost of slab leak repair in Derry, NH can vary widely, usually ranging from $1,000 to $5,000 or more, depending on the leak's location, severity, and chosen repair method. Simple direct access repairs might be on the lower end, while extensive rerouting or tunneling will be higher. We provide a clear, upfront estimate after a thorough inspection.
Detection typically takes one to three hours. Spot repairs and reroutes generally take one to two days.
Slab leaks can be caused by several factors, including shifting soil that puts stress on pipes, aggressive water chemistry leading to pinhole leaks in copper, improper pipe installation, and general aging of plumbing materials. Frost heave and shifting rocky soil can damage older sewer laterals and shallow water lines. A large share of homes rely on private wells, and some wells carry naturally occurring arsenic, radon or iron that call for treatment.
A simple direct slab leak repair can often be completed in a single day. More complex repairs involving pipe rerouting or extensive repiping might take 2 to 5 days, depending on the scope of work and the size of your Derry property. We always aim for efficient service with minimal disruption.
Yes, many slab leak repairs, especially those involving rerouting or repiping, require permits from the local permitting office to comply with building and plumbing codes. Water heater replacements, new fixtures and sewer or water line work generally need a permit where the town enforces a code. FVR Plumbing handles all necessary permitting on your behalf, so your repair is fully compliant.
Yes. We provide a written workmanship warranty, and pipe and fittings carry manufacturer warranties. We go over coverage before starting work.
Warm spots on the floor, damp carpet, cracks in tile, mildew odors, the sound of running water and a water meter that moves with fixtures off are common signs. A sudden jump in your water bill is also a clue.
Slab leak repair is a highly specialized task that should only be handled by licensed professionals. Poor detection or repair can lead to further damage to your home's foundation, mold growth, and costly structural issues. DIY attempts often void warranties and can violate local plumbing codes in Derry.
