Water Leak Detection in Walls & Ceilings in Kent, WA
Water leaks behind walls or in ceilings can go unnoticed for long periods, leading to extensive drywall damage, wood rot and mold. We use non-invasive methods like moisture meters, thermal cameras and borescopes to accurately pinpoint the source of these leaks. This approach minimizes the need for destructive investigation, saving you time and money on repairs to your home's interior.
Fixture and Appliance Leak Detection in Kent, WA
Running toilets, worn faucet cartridges and leaking water heater connections waste more water than most people realize. 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.
Main Water Line Leak Detection in Kent
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.
Gas Leak Detection in Kent
Gas leaks are extremely 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 Kent.
Irrigation and Yard Leak Detection in Kent, WA
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. 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.

Water Line Leak Detection in Kent, WA
Hidden water leaks can occur in walls, ceilings or underground pipes. These leaks often go unnoticed until significant damage is done or water bills skyrocket.

Our goal is to accurately locate the source of the leak, minimizing the need for extensive repairs to your Kent home.

Frequently Asked Questions About Leak Detection in Kent
The cost of leak detection in Kent 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 clear estimate after our initial assessment.
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.
If you suspect a gas leak, immediately evacuate everyone from the property, do not use any electrical devices, and call your gas utility company and FHN Plumbing from a safe location. Gas leaks are extremely dangerous and require immediate professional attention.
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 lasting solution.
While you can check for obvious leaks like dripping faucets, hidden leaks require professional tools and expertise. DIY attempts can often misread the problem or cause further damage, especially with slab or gas leaks.
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.
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.
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.
