Sewer Line Leak Detection in Madison, WI
Sewer line leaks can cause unpleasant odors, slow drains and potential health hazards. Our team uses camera inspections to visually identify breaks, cracks or blockages within your sewer lines.

We address sewer leaks in all types of piping materials common in Madison homes, from PVC to cast iron.
Main Water Line Leak Detection in Madison
The service line between your meter and house can leak underground for months, especially in older galvanized or copper lines. Wet spots in the yard, oddly green grass or a sinking area near the front of the house are clues. We use line tracers to map the pipe and ground microphones to hear the leak. That keeps excavation to a small, focused hole.

We handle everything from pinhole leaks to joint failures.
Hidden Wall and Ceiling Leak Detection in Madison
Leaks inside walls and ceilings often show up as stains, bubbling paint, soft drywall or a musty smell. We use thermal cameras to find temperature differences caused by water, then confirm with moisture meters. Acoustic tools help when the leak is on a pressurized line. Pinpointing the source lets us cut a small, neat access opening.
Underground Water Line Leak Detection in Madison, WI
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.

Irrigation and Yard Leak Detection in Madison, WI
Drip and sprinkler systems are a common source of hidden water loss in many yards. A cracked lateral or a stuck valve can waste thousands of gallons before anyone notices.
