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.
(503) 914-2356 — Call or TextWhere 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.

Beaverton
Washington County — ~10 mi from PortlandCopper 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.
Beaverton Leak Detection →Lake Oswego
Clackamas / Washington County — ~8 miOlder 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.
Lake Oswego Leak Detection →Milwaukie
Clackamas County — ~6 mi from PortlandMid-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.
Milwaukie Leak Detection →Tigard
Washington County — ~10 mi from PortlandMix 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.
Tigard Leak Detection →Tualatin
Washington / Clackamas County — ~14 miRivergrass 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.
Tualatin Leak Detection →Gresham
Multnomah County — ~16 mi from PortlandEast 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.
Gresham Leak Detection →Oregon City
Clackamas County — ~18 mi from PortlandOldest 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.
Oregon City Leak Detection →Hillsboro
Washington County — ~20 mi from PortlandFast-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.
Hillsboro Leak Detection →West Linn
Clackamas County — ~12 mi from PortlandMix 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.
West Linn Leak Detection →Happy Valley
Clackamas County — ~15 mi from PortlandOne 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.
How We Adapt to Each Metro Community
Portland’s metro spans three counties, five major water districts, and over a century of residential construction. Pipe materials and failure patterns vary significantly from one neighborhood to the next, and our inspection approach adjusts before we arrive.
Pipe material by era. Homes built before 1960 typically have galvanized steel supply lines, which corrode from the inside and develop pinhole failures near fittings. Copper supply pipe dominates construction from the 1960s through the mid-1980s across established neighborhoods from Lake Oswego to Northeast Portland. Polybutylene was installed widely between 1978 and 1995 — especially in Tigard, Tualatin, and Beaverton developments — and reaches high fitting-failure risk at 25 to 35 years. CPVC followed from the mid-1980s into the 2000s. PEX push-fit connections dominate construction from 2000 onward and are now showing early push-collar failures in Happy Valley and Hillsboro homes built during the early 2000s boom.
Soil and site conditions. The Portland basin sits on soft clay that contracts in dry summers and swells in wet winters, stressing buried service laterals at joints. East of Powell Butte, volcanic basalt creates harder, more abrasive conditions. Tualatin River floodplain soil in Tualatin and southern Tigard is expansive and shifts seasonally, adding unusual stress to yard line joints. Hillside lots in West Linn and Lake Oswego have long lateral runs that move with freeze-thaw cycles. Knowing local conditions shapes which part of the system we examine first.
Water district billing. Six water districts operate across our service area, and each has its own process for leak adjustment credits. We are familiar with the requirements of Portland Water Bureau, Tualatin Valley Water District, Clackamas River Water, North Clackamas Water District, South Fork Water Board, and Lake Oswego’s Lake Corporation. Our written reports are formatted to satisfy each one without a second trip or additional paperwork.
Coverage Area FAQ
How do I know if I am in your service area?
If you are within roughly 20 miles of Portland, you almost certainly are. Call (503) 914-2356 and give us your cross streets — we will confirm coverage and an arrival window on the spot.
Can you reach outlying areas the same day?
Yes, in most cases. Hillsboro, Oregon City, and Happy Valley sit near the edge of our 20-mile radius and are still reachable same day for active leak calls. Drive time from our Nicolai Street base is typically under 35 minutes to any of these areas.
Do you provide water district credit documentation for all service areas?
Yes. Our report includes meter readings, pressure test results, confirmed leak location, and photos — the documentation that Portland Water Bureau, TVWD, Clackamas River Water, North Clackamas, South Fork Water Board, and Lake Oswego Lake Corporation all require to process a bill adjustment.
Do you serve commercial and multi-family properties across the metro?
Yes. We serve commercial buildings, multi-family properties, and HOA common areas throughout the Portland metro using the same acoustic and pressure testing equipment used on residential calls. See our commercial leak detection page for details.
