Slab Leak Reroutes in Bothell
Rerouting abandons the leaking line under the slab and runs new pipe through the walls or attic. It avoids breaking concrete and often costs less than direct access under finished floors. We usually use PEX for reroutes because it handles heat and resists hard-water corrosion. This option is popular when the slab is covered in tile or hardwood.

Acoustic Slab Leak Detection in Bothell
Our technicians rely on highly sensitive acoustic listening devices to pinpoint the exact location of a leak under your slab.

Pressure Testing & Isolation in Bothell
When a leak is suspected, we can perform pressure tests on individual water lines. By isolating sections of your plumbing system and monitoring pressure gauges, we can confirm the presence of a leak and often determine which specific line is compromised. This systematic approach is crucial for homes with complex plumbing layouts, ensuring an accurate diagnosis before any excavation in Bothell, WA.
