Irrigation and Yard Leak Detection in Kirkland, 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.

Main Water Line Leak Detection in Kirkland
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.
Fixture and Appliance Leak Detection in Kirkland, 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.
Pool and Spa Leak Detection in Kirkland
Summer heat and wind can evaporate a lot of pool water, so it can be hard to tell normal loss from a leak. A bucket test compares evaporation to actual water loss. We then pressure test plumbing lines and use dye testing around lights, skimmers and fittings. Finding the leak protects the pool shell and the soil around it.
Emergency Leak Detection in Kirkland, WA
Some leaks simply cannot wait. For urgent situations like burst pipes, sudden drops in water pressure or the smell of gas, FHN Plumbing provides emergency leak detection services in Kirkland, WA.

Water Line Leak Detection in Kirkland, 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. We use non-invasive techniques like pressure testing and moisture meters to find leaks in your main water lines, supply lines and drainpipes. Our goal is to precisely locate the source of the leak, minimizing the need for extensive repairs to your Kirkland home.

Frequently Asked Questions About Leak Detection in Kirkland
The cost of leak detection in Kirkland, 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 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 professional equipment. That is where professional detection saves time and money.
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 unnecessary damage to your home, saving you time and money.
Yes. Acoustic and thermal tools let us locate most leaks without opening anything. We only open a small area once the leak is confirmed.
Most residential leak detection appointments take one to three hours. Larger homes, commercial buildings or multiple leaks can take longer. We give you an estimate when we schedule.
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 Kirkland may be necessary. We will explain any permit requirements.
Small repairs usually do not, but reroutes, repipes and main line replacements often do. Requirements vary by city and county. We take care of any permits needed.
