Port Townsend Commercial Slab & Under-Floor Leak Detection
Locating pressurized lines leaking under commercial slabs, basements and lower levels, so the floor is opened at one spot with the rest of the building in use.

Property managers, boards and owners in Port Townsend call us for commercial slab leak detection when a persistently wet hallway, utility room or lower, or when a warm or damp patch on a commercial. On multi-family along the Sheridan corridor the lines are long, the drawings are missing, and outwash sand under the historic districts hides the water. We're a dedicated trip across the Hood Canal Bridge, with the gear on the truck.
The job on Port Townsend properties
The order matters: repair or re-route, then open one spot, then patch and reopen. On Fort Worden's facilities near Sheridan Street the second step is the long one, because clay seams in the uplands and the length of the private system set the pace. The result is one opening in the slab, not and written report with photos.
When a warm or damp patch on a commercial at multi-family along the Sheridan corridor, the job is the same shape every time: repair or re-route, open one spot, patch and reopen. What changes in Port Townsend is the ground, clay seams in the uplands, and the access across Sheridan Street. What doesn't change is that nothing gets dug until it's located.
What's under Port Townsend's larger sites
What we know about Port Townsend's larger properties: port Townsend's commercial stock runs from 1880s downtown buildings with century-old lines to the marina and boatyard facilities on fill at the water, all on the City's gravity system from the Quilcene. On marinas and waterfront industry at Point Hudson and the boat haven near Point Hudson we plan for till toward Discovery Bay and for a system with no drawing.
The sandy outwash under much of the city hides leaks completely; the City bill is the sign.
On historic downtown commercial buildings near Fort Worden the trigger for commercial slab leak detection is usually a slab line that has failed before; on Fort Worden's facilities it's a musty smell in a basement or parking. Either way the ground is till toward Discovery Bay, the system is older than the staff, and we open one spot before any surface near Point Hudson is cut.
One crew, start to finish
On senior living and medical facilities near the boat haven we've done commercial slab leak detection after hours with the site taped and lit, pumps running, and residents told what to expect. A dedicated trip across the Hood Canal Bridge, and the report with photos goes to the board or owner the next morning, along with a candid note about the rest of the system under sandy bluffs above the Strait.
