Main Water Line Leak Detection in Vancouver
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.

Our technicians are equipped to handle immediate diagnoses and provide temporary solutions until full repairs can be made.
Hidden Wall and Ceiling Leak Detection in Vancouver
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.
Irrigation and Yard Leak Detection in Vancouver, WA
Drip and sprinkler systems are a common source of hidden water loss in most yards. A cracked lateral or a stuck valve can waste thousands of gallons before anyone notices. We test the irrigation system separately from the house and trace leaks along buried lines. Many water providers recommend checking irrigation first when bills spike in summer.
Leak Detection Cost Comparison in Vancouver, WA
Professional leak detection usually 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.

Fixture and Appliance Leak Detection in Vancouver, WA
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.

Frequently Asked Questions About Leak Detection in Vancouver
Leak detection in Vancouver typically costs $150 to $450 for a typical home, depending on the size of the system and the number of areas tested. Pool leak detection runs about $250 to $500. We tell you the price before we start.
FHN Plumbing stands by the quality of our work. We offer warranties on our leak detection services and any subsequent repairs. Specific warranty details will be provided with your service agreement.
Leak detection itself usually does not require a permit. However, if the leak requires significant repairs, such as replacing a section of a main water line, gas line or extensive slab repair, then a plumbing permit from Vancouver may be necessary. We will advise you on any permit requirements.
A slab leak is a leak in the water pipes embedded within or beneath your home's concrete slab foundation. Glacial till and dense hardpan are common in western Washington, and they drain poorly enough to keep water against foundations and in crawlspaces. Soil that shifts and settles puts stress on plumbing lines, and temperature swings cause pipes to expand and contract over the years.
Many homeowners policies cover the cost of finding and accessing a sudden leak, though coverage varies. We provide a written report with photos to support your claim. Check with your insurer about your specific policy.
Most standard leak detection services can be completed within 1 to 3 hours. More complex cases, such as multiple leaks or hard-to-access areas like under a slab, might take longer to accurately pinpoint.
Many rural Washington homes rely on private wells, and some carry iron, manganese or other minerals that call for testing and treatment. Hard or aggressive water can cause pinhole corrosion in copper pipes over time. Slab foundations on shifting soils also put stress on pipes underneath the house, and high water pressure in some areas adds more stress.
Turn off all water in the house and watch the meter. If the leak indicator or dial moves, water is escaping somewhere. A sudden jump in your water bill is another strong sign.
