A Lynnwood homeowner’s water bill doubled with no visible leak. The water was going somewhere — under the slab.
The clues
- A warm spot on the floor
- The meter creeping even with everything off
- A faint hiss near the water heater wall
Finding it without a jackhammer
We isolated the hot side, pressurized the line, and used acoustic detection to pinpoint the leak to a two-foot section — instead of opening the whole slab on a guess.
The fix
A targeted access cut, a clean repair, and a patch — done in a day. Catching a slab leak early is the difference between a small repair and a flooring replacement.
Little-Known Fact
A warm spot on the floor is frequently the first sign of a hot-water slab leak — before a drop of water ever shows.
