What’s Included in Our Leak Detection & Pipe Repair Services

Leak Detection

Acoustic Leak Detection

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.

Slab Leak Detection

Slab Leak Detection & Repair

A slab leak in Ontario 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.

Pipe Repair

Pipe Repair & Sectional Replacement

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

Whole-Home 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 Ontario homes with minimal downtime and complete cleanup, ensuring long-term safety and efficiency.

Water Line Upgrades

Water Line Upgrades & Code Corrections

Old plumbing systems often fall out of code or become inefficient over time. We help homeowners upgrade water lines, improve pressure balance, and bring their systems up to modern standards during leak or pipe repair work.
