Irrigation and Yard Leak Detection in Olympia, 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 jump in summer.
Hidden Wall and Ceiling Leak Detection in Olympia
Leaks inside walls and ceilings often show up as stains, bubbling paint, soft drywall or a musty smell. We use thermal cameras to spot 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.
Slab Leak Detection in Olympia
Slab leaks are a common concern for homes with concrete foundations, especially where soils shift. Our technicians use specialized 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 significant repair costs down the line. We can locate leaks in both hot and cold water lines under the slab.
Water Leak Detection in Walls & Ceilings in Olympia, WA
Water leaks behind walls or in ceilings can go unnoticed for long periods, leading to serious drywall damage, wood rot and mold.

This approach minimizes the need for destructive investigation, saving you time and money on repairs to your home's interior.

Frequently Asked Questions About Leak Detection in Olympia
The cost of leak detection in Olympia can range from $250 to $800, depending on the complexity and location of the leak. Factors like slab leaks or those requiring special equipment may be at the higher end. We provide a detailed estimate after our initial assessment.
Many homeowner's insurance policies cover the cost of repairing sudden and accidental leaks, and sometimes the cost of leak detection itself, especially if it leads to a covered repair. It's best to check your own policy or contact your insurance provider for details.
Older homes may have galvanized steel or polybutylene pipes, both known for higher leak rates due to corrosion or material degradation. Copper pipes can develop pinhole leaks over time, while PVC and PEX are usually more reliable but can still leak at fittings or due to installation errors.
If a gas leak is suspected, immediately evacuate the property and call 911 or your gas provider. Once the area is safe, FHN Plumbing can be called to precisely locate the leak and perform the necessary repairs according to strict safety protocols and codes.
We use acoustic ground microphones, thermal imaging cameras from brands like FLIR, line tracers, moisture meters and pressure test gauges. Each tool helps confirm a different type of leak. Using several together gives accurate results.
Common signs include a sudden spike in your water bill, damp spots on walls or floors, mildew odors, visible mold growth, the sound of running water when no fixtures are in use, or a constantly running water meter even when all water is off.
While you can check for obvious leaks, hidden leaks often require professional equipment like acoustic sensors, thermal cameras or tracer gas to locate precisely. A professional plumber will pinpoint the source without unnecessary damage to your home, saving you time and money.
We use a range of professional tools including acoustic listening devices, thermal imaging cameras, specialized moisture meters, pressure testing equipment and tracer gas detectors for precise and non-invasive leak identification.
