Leaks inside walls and ceilings stay invisible until the damage is done. Our Covina pipe leak detection service traces hidden supply and drain leaks to their exact source, so repairs open one small section instead of whole walls.
A supply line leaking inside a Covina wall can drip for months. The first visible sign is often a brown ceiling stain, bubbling paint, or a musty closet, by which time drywall, insulation, and framing have been soaking. Older Covina neighborhoods still carry galvanized and early copper plumbing that corrodes from the inside, which makes hidden pipe leaks one of the most common calls we run.
We find these leaks with a combination of acoustic sensors that pick up the hiss of escaping water and moisture meters that map how far dampness has spread behind the surface. That mapping matters: it tells the repair crew exactly how much drywall to open and confirms nothing is missed behind an adjacent wall.
Pressurized supply leaks announce themselves through sound and meter movement, so we start with a meter test and a listening sweep. Drain leaks are quieter and usually show as stains below bathrooms and kitchens, so we trace those with moisture mapping and targeted camera work. In Covina homes where both systems run through the same walls, we check both before concluding anything.
When the leak sits under the foundation rather than in a wall, our slab leak detection in Covina takes over with concrete-penetrating equipment. One team, one visit, one confirmed answer.
Yes. Acoustic sensors and moisture meters locate the source through drywall and plaster. We mark the spot and only then open the smallest area needed for repair.
A moving meter with all fixtures off almost always means a pressurized leak somewhere in the system. It is one of the most reliable leak indicators we check in Covina homes.
Usually a single square foot or less, because the leak is pinpointed first. Exploratory demolition across whole walls is what happens when leaks are guessed at, not detected.
Yes. Drain and sewer line leaks inside walls and under floors are part of every pipe leak visit. For yard-side sewer issues, see our sewer leak detection in Covina.
One call gets a Covina leak detection specialist to your door, with the equipment to find it the same visit.
