Electronic Acoustic Leak Detection in Passaic
Our team uses electronic listening devices to pinpoint the precise location of a slab leak. These highly sensitive microphones can detect the faint sound of water escaping from a pressurized pipe under your foundation. This non-invasive method helps us avoid unnecessary concrete breaking, saving you time and money on repairs. It's especially effective for copper and PEX lines commonly found in Passaic homes.

Cold Water Slab Leak Detection in Passaic, NJ
Cold water slab leaks do not create warm spots, so they are more difficult to see. They often show up as a running water meter, damp carpet, a musty smell or water seeping at baseboards. We isolate the cold side and use acoustic equipment to listen for the leak through the slab. Line tracers map the pipe route so we know exactly where to listen.
Cost-Effective Slab Leak Detection in Passaic
Investing in professional slab leak detection with GLN Plumbing is a budget-friendly solution compared to the long-term damage of an undetected leak. Our accurate diagnosis prevents unnecessary excavation and helps you address the problem before it escalates into expensive foundation repairs or mold remediation, protecting your investment in your Passaic property.
Slab Leak Repair Through Direct Access in Passaic, NJ
When a single leak is found on otherwise healthy pipe, direct access can be the most economical repair. We cut a small opening in the floor at the marked spot, repair the pipe and pressure test it. Then we patch the concrete and leave the area ready for flooring. Accurate detection keeps that opening as small as possible.
Emergency Slab Leak Detection in Passaic
A sudden drop in water pressure, visible dampness or the sound of running water can signal an emergency slab leak. GLN Plumbing offers emergency detection services in Passaic to address urgent situations quickly. We prioritize rapid response to limit water damage and prevent further structural compromise to your property.
Pressure Testing & Isolation in Passaic
When a leak is suspected, we can perform pressure tests on individual water lines. By isolating sections of your plumbing system and monitoring pressure gauges, we can confirm the presence of a leak and often determine which specific line is compromised. This step-by-step approach is crucial for homes with complex plumbing layouts, ensuring an accurate diagnosis before any excavation in Passaic, NJ.
