Underground Water Line Leak Detection in Dover, NH
Leaks in underground water lines, often leading from the meter to your home, can result in serious water loss and property damage. We use 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.
Fixture and Appliance Leak Detection in Dover, NH
Running toilets, worn faucet cartridges and leaking water heater connections waste more water than most people think. A silent toilet leak can lose hundreds of gallons a day. We check flappers, fill valves, supply lines, softeners and water heater fittings. These repairs are typically quick and inexpensive.
Gas Leak Detection Services in Dover
Gas leaks are extremely dangerous and require immediate professional attention. Our team is equipped with highly sensitive gas leak detectors to promptly identify the location and severity of any gas escape. We put safety first and will guide you through the necessary steps, including shutting off the gas supply and coordinating with your utility company, to make sure your home is secure.
Leak Detection Cost Comparison in Dover, NH
Professional leak detection typically costs $150 to $450 for a standard home, depending on the system size and how many areas need testing. Pool leak detection usually runs $250 to $500. Repair costs vary a lot, from $150 for a fixture fix to several thousand dollars for a slab reroute. Accurate detection keeps the repair cost as low as possible.
Hidden Wall and Ceiling Leak Detection in Dover
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, clean access opening.
Main Water Line Leak Detection in Dover
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, targeted hole.

Sewer Line Leak Detection in Dover, NH
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. This method allows for accurate location of the leak without guesswork, leading to more efficient and targeted repairs. We repair sewer leaks in all types of piping materials common in Dover homes, from PVC to cast iron.
