Slab Leak Detection & Repair in Seattle
Slab leaks are common where soil shifts and puts stress on pipes embedded in concrete foundations. Glacial till and dense hardpan are common in western Washington, and they drain poorly enough to keep water against foundations and in crawlspaces. We use non-invasive acoustic and thermal imaging equipment to pinpoint the exact location of the leak beneath your home's foundation in Seattle. Our repair options range from targeted slab penetration to re-routing the affected line, minimizing disruption and protecting your foundation from further damage. We work with all types of piping found in slab foundations, including copper and PEX, ensuring a durable fix that complies with local building codes.
Yard and Main Line Leak Repair in Seattle, WA
The service line between the meter and your house can crack from rocky soil, roots or ground movement.

For long or deep lines, a new trenchless line may be the smarter choice.

Typical signs of a hidden water leak include unexplained spikes in your water bill, discolored or damp spots on walls or ceilings, a persistent musty odor, the sound of running water when no fixtures are in use, or warm spots on your floor (indicating a hot water slab leak).

Regular maintenance and water softening systems can help reduce these effects.
If you discover a major water leak, the first step is to locate and turn off your home's main water supply valve to prevent further damage. Then, contact FHN Plumbing right away at (425) 491-3131 for emergency water leak repair in Seattle, WA. Try to contain the water if possible.
