The Danger Under Your Foundation

In neighborhoods across Hillsborough (CDP) and surrounding areas, many homes are built on concrete slab foundations with plumbing lines routed directly beneath or within the concrete. When these pipes leak, the water has nowhere to go but up into your flooring or down into the soil, risking foundation settlement.

Warning Signs of a Slab Leak

Unexplained warm spots on your tile or hardwood floors.
The sound of running water under the floor.
Buckling or cracking flooring materials.
Damp carpets or a persistent musty smell.
A rapidly increasing water bill.

Local Causes

Slab leaks are often caused by the natural shifting of New Jersey soil over time, which puts pressure on aging copper pipes. Friction against the concrete and chemical reactions with the soil can cause pinhole leaks to form. Sometimes, it starts as a hidden water leak inside a lower wall that mimics a slab leak, which is why accurate detection is crucial.

Are your floors suspiciously warm?

This is a classic sign of a hot water slab leak. Call us before the foundation is compromised.

Our Detection Method, Step by Step

Meter Testing: We verify the leak by checking the main water meter while all fixtures are off.
Line Tracing: Using electromagnetic locators, we map out the path of the pipes beneath the concrete.
Acoustic Listening: We use ultra-sensitive ground microphones to listen through the slab and locate the loudest point of escaping water.
Confirmation: We pinpoint the exact spot, drastically reducing the area of concrete that needs to be removed for repair.

What Happens After the Leak is Found?

Because we mark the exact location, you won't need a contractor to jackhammer your entire living room. Repair options typically include breaking a small section of concrete for a spot repair, or bypassing the leaking line entirely by routing a new pipe through the attic or walls. We will explain the most sensible approach.

Cost Factors Explained

The cost to fix a slab leak depends on the depth of the pipe, the type of flooring above it, and whether a direct repair or a pipe reroute is chosen. If the leak is actually outside the foundation, it might be a water line leak instead.

Prevention Tips

Keep your water pressure regulated (ideally under 80 PSI) to reduce stress on pipes under the slab. Avoid pouring harsh chemical drain cleaners that can corrode pipes from the inside.

Frequently Asked Questions

Will you have to break my floor to find the leak?

No. We find the leak electronically and acoustically first. The floor is only opened when the repair begins, and only in a very small targeted area.

Is this considered an emergency?

Yes, a slab leak can wash away the soil supporting your foundation. Shut off your water and call for emergency leak repair.

Does homeowner's insurance cover slab leaks?

Policies vary. Insurance often covers the water damage and the cost to access the pipe (the tear-out and put-back), but not always the plumbing repair itself.
