Main Water Line Leak Detection in Seattle
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.
Slab Leak Detection in Seattle
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 real repair costs down the line. We can locate leaks in both hot and cold water lines under the slab.
Gas Leak Detection in Seattle
Gas leaks are very dangerous and require immediate professional attention. FHN Plumbing provides rapid response gas leak detection services using highly sensitive detectors to identify even the smallest gas leaks in your home or business. We prioritize safety and will work quickly to locate the leak, advise on necessary repairs and make sure your gas lines are secure and up to code in Seattle.

Whether your Seattle home has modern PEX plumbing or traditional copper pipes, leaks can occur. We are proficient in detecting leaks in all common piping materials found in Washington homes.

We handle everything from pinhole leaks to joint failures.
Water Line Leak Detection in Seattle, WA
Hidden water leaks can occur in walls, ceilings or underground pipes. These leaks often go unnoticed until serious damage is done or water bills skyrocket.

Irrigation and Yard Leak Detection in Seattle, WA

Frequently Asked Questions About Leak Detection in Seattle
The cost of leak detection in Seattle, WA can range from $250 to $800, depending on the complexity and location of the leak. Factors like slab leaks or hard-to-reach pipe leaks may be at the higher end. We provide a written estimate after our initial assessment.
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 continuously 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 needless damage to your home, saving you time and money.
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 clear sign.
Municipal water west of the mountains in Washington is typically soft, while supplies on the drier east side tend to run harder. 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 strain.
To prevent future leaks, consider regular plumbing inspections, especially for older homes. Keep water pressure in a safe range, address any signs of corrosion and maintain your plumbing system. For homes with known issues, proactive repiping or pipe upgrades can be a long-term solution.
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.
You can check your meter, test toilets with food coloring in the tank and look for damp spots. Finding leaks under slabs or inside walls requires specialized equipment. That is where professional detection saves time and money.
