Professional Nitrogen & Helium Leak Detection

Nitrogen and helium leak detection is one of the most precise methods for locating hard-to-find underground and slab leaks. This process uses an inert tracer gas introduced into the plumbing system, which safely escapes at the leak location and is detected with specialized equipment.

This method is ideal when traditional acoustic or thermal methods are inconclusive, especially for deep underground lines, slab leaks, and complex plumbing systems. It allows for pinpoint accuracy without unnecessary excavation or damage.

Mac & Sons Leak Detection provides nitrogen and helium leak detection services throughout Bluffton, Hilton Head, Beaufort, Okatie, and the surrounding Lowcountry, delivering accurate results when precision matters most.
