We use high-sensitivity listening devices to pick up the sound of water escaping from pipes—even through concrete, drywall, or flooring. This non-invasive method is perfect for locating leaks in walls or slabs with minimal disruption to your home.

A slab leak in Montclair can go unnoticed until it causes serious structural damage. We identify slab leaks quickly and offer solutions such as localized repairs, rerouting, or direct access through the slab. We’ll explain the pros and cons of each and help you choose the best option.

Pressure Testing

Pressure & Moisture Testing

When a leak is suspected but not visible, we use pressure testing and moisture mapping to confirm its presence. These tools allow us to narrow down the source and avoid unnecessary wall or floor demolition.

For accessible leaks or small damaged sections, we offer quick pipe repair using modern, durable fittings and materials. Whether it's a pinhole in copper or a cracked PVC joint, we’ll isolate and fix the issue with precision.

Re-Piping

If your home has constant leaks, poor water pressure, or signs of pipe corrosion, re-piping may be the best investment. We handle re-piping Montclair homes with minimal downtime and complete cleanup, ensuring long-term safety and efficiency.
