Slab leaks are one of the most expensive and disruptive plumbing issues a homeowner can face—and if you live in New Jersey, your risk might be higher than you think.
Here’s why homes across the Garden State are especially prone to slab leaks, what causes them, and how to detect them early.
🏠 First, What Is a Slab Leak?
A slab leak happens when a water line running beneath your home’s concrete foundation cracks, corrodes, or bursts. Because it’s hidden under the slab, the leak can go unnoticed for months—causing serious structural and water damage.
⚠️ Why NJ Homes Are at Higher Risk
- Older Housing Stock
Many homes in New Jersey were built 40+ years ago, using copper or galvanized steel pipes directly embedded in or under the slab. Over time, these pipes corrode, weaken, and eventually leak.
- Shifting Soil and Freeze-Thaw Cycles
NJ’s cold winters and humid summers cause the ground to expand and contract, stressing buried pipes. This ground movement can cause small pipe fractures over time—especially in slab-on-grade homes.
- Hard Water and Soil Chemistry
Many parts of New Jersey have hard water, which leads to mineral buildup and internal pipe corrosion. Combined with certain acidic soils found in Central and South Jersey, this accelerates pipe decay from the outside too.
- Construction Practices
In older NJ neighborhoods, it was common to run uninsulated hot and cold water lines beneath the slab to save on construction costs—making leaks more likely to occur and harder to detect.
🕳️ Signs You Might Have a Slab Leak
