#1 Slab Leak Detection in New Jersey
Slab Leak Detection – Protect Your Home’s Foundation
What is slab leak detection?
A slab leak happens when plumbing lines beneath a building’s concrete foundation develop leaks or bursts due to corrosion, pressure changes, or shifting soil. These leaks can go unnoticed for long periods, causing severe structural damage, mold growth, foundation instability, and skyrocketing utility bills.
Since slab leaks occur beneath the concrete, early detection is essential to avoid costly repairs and extensive property damage. Professional detection methods can pinpoint leaks before they threaten your home’s safety and value.
Common Causes of Slab Leaks
✔ Corroded Pipes – Over time, metal pipes deteriorate due to chemical reactions in the water or soil.

✔ High Water Pressure – Excessive pressure can weaken pipes, leading to cracks and bursts.
✔ Shifting Soil & Foundation Settling – Soil movement due to weather, erosion, or seismic activity can stress and break pipes.
✔ Poor Construction or Pipe Installation – Inferior materials or faulty workmanship can lead to premature leaks.
✔ Abrasion & Friction – Pipes that rub against concrete or gravel over time can develop leaks from constant wear.
Signs You May Have a Slab Leak
🚨 Unexplained High Water Bills – A sudden spike in water usage may indicate a hidden underground leak.
🚨 Warm or Damp Spots on Floors – A hot water leak may create warm areas on your flooring.
🚨 Cracks in Walls or Flooring – Leaking water can weaken the foundation, leading to structural damage.
🚨 Mold or Mildew Growth – Persistent dampness under flooring can cause mold and musty odors.
🚨 Low Water Pressure – A slab leak can reduce water flow throughout your home.
🚨 Hearing Running Water – If you hear water running when no faucets are on, a hidden leak might be the cause.
🚨 Pooling Water Around the Foundation – Unexplained moisture or puddles near your home’s exterior may signal a leak beneath the slab.
Ignoring these warning signs can lead to serious structural instability, expensive foundation repairs, and long-term property damage.

Water Leak Detection Q&A
To detect a leak under a slab, look for signs like unexplained high water bills, damp spots, mold, or warm flooring. Use acoustic listening devices or infrared cameras to locate hidden leaks. A Leak detection company or plumber can confirm with pressure testing.
To fix a leak under a concrete slab, options include spot repair by jackhammering the slab, rerouting pipes above ground, or pipe lining with epoxy. A plumber will assess the best method based on leak severity and location.
Detecting a slab leak typically costs between $150 and $800, depending on the location, severity, and methods used. Techniques like acoustic listening, infrared imaging, and tracer gas detection can impact the final price. Tracer gas is especially useful for pinpointing hard-to-find leaks by injecting a harmless gas into the pipes and using sensitive detectors to locate where it escapes. Prices may vary by region, leak detection contractor and plumbing company.
A slab leak can go undetected for weeks, months, or even years if signs are subtle. Small leaks often show no surface symptoms at first, but over time, they can cause rising water bills, mold, or foundation damage. Regular inspections help catch issues early.
