Interior Water Leak Detection for Poulsbo Homes and Properties
Pinpointing leaks on the supply lines inside the house: in walls, ceilings, crawlspaces and under slabs, without opening finishes on a guess.

For interior water leak detection in Poulsbo, know this first: water comes from the City of Poulsbo or Kitsap PUD, the private line is yours, and it runs through bay-side outwash that drains instantly. We isolate hot and cold before anything else, because water surfacing downhill on Finn Hill rarely points at the actual break.
Poulsbo leak detection, step by step
An interior locate in Poulsbo starts by proving the leak is inside: the meter test with the house isolated at the main shutoff. Then hot and cold are separated at the water heater, the lines are traced through the crawlspace or walls of compact lots near Front Street, and the acoustic sensor, thermal camera and moisture meters narrow it to one wall or one square of floor.
If you're near Front Street or Fish Park and you've noticed a wet crawlspace near the bay, the odds are on long HDPE pulls to Big Valley acreage in till with roots out Big Valley Road. That's a job for interior water leak detection, not a guess with a shovel.
The ground decides how a leak shows itself. With till with roots out Big Valley Road on acreage along Big Valley Road, water travels the trench and surfaces as a wet crawlspace near the bay, often nowhere near the pipe.

The locate is instruments only: gauges on each side of the water heater, acoustic listening along the traced lines, thermal imaging for a hot-side leak, moisture mapping to the source. The one opening happens at the mark, and our licensed plumbers repair it there.
