Leak Detection Service Areas — Portland Metro
We serve Portland and communities within approximately 20 miles. Slab leak detection, yard lateral tracing, and supply line testing for homes and commercial properties across the metro.
Where We Work
Leak Detection Portland operates from our base at 2455 NW Nicolai St, Unit 200, Portland, OR 97210. From there, we cover the Portland metro and surrounding Washington and Clackamas County communities. Drive times are typically under 30 minutes to most service addresses, and same-day appointments are available in most areas.
Each area page below covers the specific conditions we see in that community — local pipe materials, soil types, water district billing questions, and common failure patterns we encounter. If you know roughly where you are, pick your area for location-specific information. If you are in Portland proper, the main site has you covered.
Service Area Pages

Beaverton
Washington County — ~10 mi from Portland
Copper slab leaks are common in 1970s–1990s Beaverton homes. The Tualatin Valley Water District serves most of Beaverton; we provide the documentation TVWD requires for leak adjustment credits.
Lake Oswego
Clackamas / Washington County — ~8 mi
Older copper in Westlake and First Addition, plus slab homes near the lake. Lake Oswego’s Lake Corporation water system has its own billing process; we understand both LO and Portland Water Bureau service areas.
Milwaukie
Clackamas County — ~6 mi from Portland
Mid-century homes with cast iron drain lines, older copper supply, and clay soil that shifts. North Clackamas Water District covers most of Milwaukie. We see slab and crawl space homes here in roughly equal proportion.
Tigard
Washington County — ~10 mi from Portland
Mix of 1960s ranch homes and newer slab construction in Metzger and Bull Mountain neighborhoods. Tualatin Valley Water District is the primary provider. Polybutylene pipe is prevalent in homes built 1978–1995.
Tualatin
Washington / Clackamas County — ~14 mi
Rivergrass and adjacent 1980s developments have high polybutylene prevalence. Floodplain soil means yard lateral issues are common. TVWD serves most of Tualatin and offers leak adjustment credits with proper documentation.
Gresham
Multnomah County — ~16 mi from Portland
East metro area with significant 1970s and 1980s housing stock. City of Gresham water utility serves most addresses. Volcanic basalt soil east of the city creates different pressure dynamics than the Portland basin.
Oregon City
Clackamas County — ~18 mi from Portland
Oldest city in Oregon, with correspondingly older infrastructure in the historic hilltop district. South Fork Water Board serves much of the area. Older galvanized and copper pipe common in homes near the Willamette.
Hillsboro
Washington County — ~20 mi from Portland
Fast-growing tech corridor with significant 2000s–2010s PEX and CPVC construction. Clean Water Services bills most Hillsboro addresses; we provide documentation for leak adjustment requests.
West Linn
Clackamas County — ~12 mi from Portland
Mix of 1960s–1980s copper homes in Bolton and Willamette neighborhoods with newer PEX on the hillside. Clackamas River Water serves most addresses. Steep lots mean longer service laterals prone to movement.
Happy Valley
Clackamas County — ~15 mi from Portland
One of Oregon’s fastest-growing cities with housing concentrated in the 2000s–2010s era. PEX push-fit connections from the building boom are now reaching failure age. Clackamas River Water serves most addresses.

What We Bring to Every Service Call, Wherever You Are
Acoustic Leak Detection Equipment
We carry calibrated acoustic amplifiers and ground microphones to every appointment. These locate leaks under concrete slabs and in yard laterals without excavation.
Pressure Testing Gear
Zone isolation with nitrogen or compressed air confirms whether a leak exists and which branch it’s in before acoustic work begins. This step is fast and definitive.
Written Report at Every Visit
Meter readings, pressure test results, acoustic findings, and a marked location diagram. Your plumber, insurer, and water district all ask for exactly this documentation.
No Repair Conflict of Interest
We detect. We don’t repair. That means our only incentive is an accurate location — not a larger excavation scope or a reason to open more concrete.
Same-Day Availability
For active leaks, we prioritize response time. If water is damaging flooring or drywall, shutting the main stops the damage without affecting our detection process.
Water District Credit Documentation
Tualatin Valley Water District, Portland Water Bureau, North Clackamas, and most other districts in our service area offer bill adjustment credits. Our report satisfies the documentation they require.
