How We Detect Hidden Plumbing Leaks in Covina

We use advanced technology to accurately locate hidden plumbing leaks while avoiding unnecessary damage to your property. Our process often starts with a visual inspection, then moves to specialized equipment such as acoustic listening devices and thermal imaging to pinpoint leaks behind walls, under concrete, or in ceilings. We also utilize high-resolution in-pipe cameras to inspect the inside of your plumbing system. These cameras show us exactly where the problem is—whether it’s a cracked pipe, loose connection, or corrosion—so we can recommend the right solution.

• Initial visual assessment – We inspect all accessible plumbing and check for visible signs of leakage.
• Use of acoustic listening devices – These help us detect leaks behind walls or beneath concrete.
• Thermal imaging – We identify temperature differences behind surfaces, which can reveal hidden moisture or an active leak.
• Pipe camera inspections – Cameras help us view the inside of pipes in real time and spot cracks, corrosion, or joint failures.
• Tailored repair recommendations – After finding the problem, we provide solutions designed for your property and situation.

For customers looking for a leak detection plumber Covina trusts, we tailor our approach based on your home’s construction, age, and plumbing history. In homes with slab foundations, our team checks for warm spots, unexplained dampness, or sounds from under the flooring as signs of a slab leak. We also frequently inspect main water lines running beneath yards, especially in older Covina neighborhoods, where tree roots and ground movement can impact underground pipes. Early and accurate identification means repairs are focused, cost-effective, and cause as little disruption as possible.
