Slab Leak Detection in Norwalk
We start by shutting off fixtures and watching the meter to confirm 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 Norwalk, CT
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. We are experienced 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 Norwalk, CT property, following health and safety codes.
Cold Water Slab Leak Repair in Norwalk
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, find the leak and repair or reroute it. Fixing cold leaks promptly helps protect your foundation.

Electronic Slab Leak Detection in Norwalk
Locating a hidden slab leak takes specialized tools.

PEX Repiping for Slab Leaks in Norwalk, CT
If multiple slab leaks point to 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 Norwalk home, providing a brand-new, leak-free plumbing system that will last for decades.

Slab Leak Pipe Rerouting in Norwalk
For more complex or recurring slab leaks, or when the original piping is severely deteriorated, pipe rerouting is an excellent 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 Norwalk with aging copper or galvanized pipes.

Frequently Asked Questions About Slab Leak Repair in Norwalk
Slab leak detection usually costs $150 to $450. Spot repairs through the slab usually run $1,500 to $4,000, and reroutes often range from $1,800 to $5,000. Whole-house repipes are quoted based on home size.
GLV Plumbing stands behind our slab leak repair work with a comprehensive warranty on parts and labor. The specific terms of the warranty will be provided with your estimate, for peace of mind about the durability and quality of our repairs in Norwalk.
Yes. We provide a written workmanship warranty, and pipe and fittings carry manufacturer warranties. We go over coverage before starting work.
Homeowner's insurance policies vary, but many cover the cost of damage caused by a sudden and accidental slab leak, although the repair of the pipe itself might not be covered. It is best to check with your insurance provider right away after detecting a leak. We can help provide needed documentation for your claim.
Simple spot repairs often do not need a permit, but reroutes and repipes may, depending on your city. We take care of permits when required.
A slab leak specifically refers to a leak in the plumbing pipes embedded within or beneath your home's concrete slab foundation. Other water leaks might occur in exposed pipes, walls, or ceilings, but slab leaks are hidden and often more challenging to detect and repair due to their location.
Older homes in Norwalk with copper or galvanized steel pipes are often more susceptible to slab leaks due to corrosion and material wear over time. While PEX is more flexible and resistant to corrosion, it can still experience leaks from installation errors, excessive pressure, or physical damage. Our team repairs all common pipe types.
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 Norwalk property. We always aim for efficient service with minimal disruption.
