Water Leak Detection in Walls & Ceilings in San Jose, CA
Water leaks behind walls or in ceilings can go unnoticed for long periods, leading to extensive drywall damage, wood rot and mold. We use non-invasive methods like moisture meters, thermal cameras and borescopes to precisely pinpoint the source of these leaks. This approach minimizes the need for destructive investigation, saving you time and money on repairs to your home's walls and ceilings.
Pool and Spa Leak Detection in San Jose
Summer heat and wind can evaporate a lot of pool water, so it can be hard to tell normal loss from a leak. A bucket test compares evaporation to actual water loss. We then pressure test plumbing lines and use dye testing around lights, skimmers and fittings. Finding the leak safeguards the pool shell and the soil around it.
Underground Water Line Leak Detection in San Jose, CA
Leaks in underground water lines, often leading from the meter to your home, can result in serious water loss and property damage. We employ ground microphones and tracer gas detection to locate these buried leaks precisely. Factors like tree roots, ground shifting and corrosion in older galvanized pipes can contribute to these issues, making professional detection essential.
Slab Leak Detection in San Jose
Slab leaks are a common concern for homes with concrete foundations, especially where soils shift. Our technicians use dedicated acoustic equipment and thermal cameras to pinpoint leaks under your home's foundation without destructive digging. Early detection of a slab leak prevents serious structural damage and mold issues, saving you real repair costs down the line. We can locate leaks in both hot and cold water lines under the slab.
