Washington County's wet marine climate, ultra-soft Bull Run water, and mix of older crawlspace homes create three distinct leak patterns we resolve every week.

Basement & Crawl Space Leaks

Beaverton's 37-inch annual rainfall keeps soil saturated from October through May. That constant moisture builds hydrostatic pressure against basement walls and floods crawlspaces through sump pump failures and foundation cracks. This is the leak pattern we see most often in Cedar Hills, Murray Hill, and older Central Beaverton homes : and it worsens each winter.

Our detection team uses moisture meters, thermal cameras, and pressure testing to tell the difference between a plumbing leak and groundwater intrusion before any wall gets opened. Learn more about our basement leak detection and repair services for Washington County homes.

Pinhole Leaks in Copper Pipe

Bull Run water, the source behind most Beaverton taps, is among the softest municipal water in America, measuring under 1 grain per gallon. Before Tualatin Valley Water District's current pH corrosion control, that very soft, slightly acidic water leached copper from the inside of supply lines. Homes in the 1960s-to-1990s cohort spanning Cedar Hills, Garden Home, and Highland Beaverton are now hitting the failure window for those copper installs.

One small drip behind a wall runs 24 hours a day for weeks before it shows up as a stain. Our pinhole leak detection service finds the failure point acoustically, without opening drywall unnecessarily.

Slab Leaks

Newer Beaverton neighborhoods, specifically Triple Creek, Bonny Slope, and the Progress Ridge corridor, sit on slab foundations, and those slabs carry copper or PEX supply lines that can fail from shifting Tualatin Valley soils, settling foundations, or pipe age. A slab leak left unchecked erodes the concrete from below, warps flooring above, and drives water bills up silently for months.

Electronic listening equipment lets us pinpoint the leak location through the concrete, so the repair opening is targeted and exact. Our slab leak detection and repair process starts with detection, not demolition.

Beaverton's Four Housing Eras: What's Leaking in Each

The age of your home tells us almost everything about what pipe material is under the floor and which failures to look for first. Here is how Beaverton's four construction cohorts line up.

Pre-1955 historic home in Central Beaverton Oregon showing galvanized-pipe era housing stock Pre-1960

Central Beaverton, Vose, West Slope, Raleigh Hills

Bungalows and mid-century ranches on crawlspace and pier foundations. Original galvanized supply lines are well past their rated lifespan : many have corroded internally to pencil-diameter flow. Cast iron drain stacks show tuberculation-related slowdowns and cracks.

Common call: pressure drop, rust-tinted water, or slow drain in a vintage home. Often the beginning of a whole-house repipe conversation, or an isolated sewer line leak in an older lateral.

Galvanized + Cast Iron
Mid-century 1960s-1980s ranch home in Cedar Hills Beaverton showing copper-pipe era neighborhood 1960s – 1980s

Cedar Hills, Garden Home, Highland Beaverton, West Slope

Ranch-style and split-level homes on crawlspaces. Copper supply lines now 45-65 years old, the precise age window when TVWD's historical soft, low-pH Bull Run water causes pinhole pitting failures. This cohort generates the most pinhole leak calls in Washington County.

A single pinhole in a copper line can spray unseen inside a wall cavity for weeks. Thermal imaging catches the moisture signature before structural wood rot sets in.

Aging Copper, Pinhole Zone
1980s – 2000s

Murray Hill, Sexton Mountain, Greenway, Five Oaks, Cooper Mountain (lower)

Planned subdivisions on crawlspaces and early slabs. Copper mid-cohort : some installs approaching pinhole age. Polybutylene alert: some 1980s Washington County homes have gray polybutylene supply lines, which degrade with chlorinated water and fail without warning. Mid-1990s to mid-2000s slabs may have CPVC that is now cracking with age.

If your Murray Hill or Five Oaks home still has gray poly, proactive replacement through a full repipe eliminates future emergency calls. Foundation settlement in this era also drives foundation leak calls.

Mid-Copper + Poly Risk + CPVC
Newer 1990s-2000s suburban development in Murray Hill Beaverton showing PEX-era construction 2000s – Present

Bonny Slope, Triple Creek, Whitford, Cooper Mountain (upper), Progress Ridge

Modern construction on slab foundations with PEX supply and PVC drain systems. Younger pipe, lower failure rate, but slab settlement and shifting Tualatin Valley soils still stress joints. Sump pump failures in any home with a basement or crawlspace are a seasonal risk every wet PNW winter.

Slab leaks in this cohort are usually soil-movement-driven rather than pipe-age-driven. Our electronic slab leak detection locates the failure through the concrete without a jackhammer guess.

Beaverton's Water Chemistry

Bull Run Water Is Ultra-Soft : and That Matters for Your Pipes

Tualatin Valley Water District (TVWD) serves most of Beaverton from two sources: approximately 70% from the Portland Water Bureau's Bull Run watershed in Mt. Hood National Forest, and about 30% from the Joint Water Commission (JWC) using Hagg Lake and Barney Reservoir. Bull Run water measures just 6-11 mg/L hardness, under 1 grain per gallon, making Beaverton's tap water among the softest municipal supplies in the United States.

For drinking, cooking, and appliances, ultra-soft Bull Run water is excellent, no scale buildup, no spotting, no mineral deposits on showerheads. But soft water has a different relationship with copper pipe that Beaverton homeowners in older homes need to understand.

Very soft water with low alkalinity carries more dissolved carbon dioxide, which can make it mildly acidic. Before TVWD and the Portland Water Bureau implemented today's corrosion-control pH adjustments, targeting around 8.8 for Bull Run source water, that slightly acidic water was slowly leaching copper from the inside of supply lines installed in the 1960s through early 1990s. The result, documented across the Portland metro area, is pinhole pitting on 1970s and 1980s copper pipe that is now showing up as unexplained wet spots in walls, higher water bills, and green staining on exposed fittings.

If you live in Cedar Hills, Garden Home, West Slope, or any Beaverton neighborhood where homes predate 1990, this is the leak risk most likely hiding in your walls right now. Our pinhole leak detection service uses acoustic and electronic equipment to find those failures before they become mold or structural damage. For homes showing multiple pinhole events, our team discusses whether targeted repair or a full repipe makes better economic sense for the years ahead.

About Us

Rooted in Washington County, Built for the Tualatin Valley

Beaverton Leak Repair Experts serves the City of Beaverton and the surrounding Washington County communities that make up the Portland westside : from the older galvanized-pipe neighborhoods of Central Beaverton and Vose to the newer PEX-plumbed builds above Cooper Mountain and Triple Creek.

This part of Oregon runs on ultra-soft Bull Run water and experiences some of the wettest winters in the continental United States. Both facts shape the leak patterns we find every day: pinhole copper corrosion in the 1960s-1990s housing cohort, and basement or crawlspace moisture driven by the Tualatin Valley's seasonally saturated soils. We know these patterns because this is where we work.

Every job starts with detection : acoustic sensors, thermal imaging, pressure testing : before any wall is opened. Oregon CCB licensed and plumbing licensed. Call (503) 974-3329 for same-day service across all 29 areas we cover in Washington County.

From Cedar Hills to Hillsboro, we respond to every type of water leak : including the often-overlooked sewer line leaks that develop under Central Beaverton and Vose's aging cast-iron laterals.

Common Questions

Beaverton Leak Detection : Frequently Asked Questions

The four most reliable signs in Beaverton homes are an unexplained spike in your TVWD water bill, warm or wet spots on your floor, the sound of running water when every fixture is off, and lower pressure than normal at your taps. Slab leaks under Tualatin Valley silt loam soil are common in the 1980s-2000s build era in Murray Hill, Sexton Mountain, and Five Oaks, areas where the original slabs have had decades of seasonal soil movement. If you notice any of these signs, our slab leak detection service can confirm and locate the failure without tearing up the floor first.

Bull Run water is extraordinarily soft, typically 6 to 11 milligrams per liter, well under 1 grain per gallon. Water that soft contains very few dissolved minerals, which means it arrives at your pipes with room to dissolve more. Without sufficient pH buffering, very soft water can be mildly aggressive toward copper, slowly leaching metal from the pipe interior over years and decades. This process, documented across the Portland metro area, produces the characteristic pinhole failure: a tiny pit that eventually punches through the pipe wall. TVWD now maintains corrosion-control pH adjustments, but Beaverton homes with copper installed before those controls were in place, particularly in Cedar Hills and Garden Home, are finding those pipes in the failure window today. Our pinhole leak detection team identifies the failure points acoustically without demolition.

In most cases, yes. Beaverton receives roughly 37 inches of precipitation per year, concentrated between October and May, the Tualatin Valley soil stays saturated for six-plus months annually. That persistent saturation builds hydrostatic pressure against basement walls and floors. A working sump pump is the primary defense against that pressure causing a flooded basement or crawlspace. A failed pump during a January storm is an emergency in Washington County. If you have a basement or crawlspace and are unsure about your sump pump's condition, our sump pump service includes inspection and same-day repair or replacement.

Acoustic detection, also called electronic leak detection, listens for the sound that pressurized water makes as it escapes a pipe. Sensitive microphones and ground-contact sensors amplify that sound signature through walls, concrete, and soil, letting our technicians trace it to the source. It works best for pressurized supply lines where water is actively moving through the breach. Thermal imaging uses an infrared camera to detect temperature differences in materials, wet areas show as cooler zones (evaporative cooling) or warmer zones (hot water lines) on the camera display. It excels at mapping moisture spread through walls and finding the boundaries of water damage. We typically use both methods together, starting with acoustic detection to locate the pipe and confirming the extent of moisture impact with thermal imaging. Learn more about our acoustic leak detection and thermal imaging leak detection services.

We answer calls 24 hours a day, seven days a week, and dispatch to Beaverton and surrounding Washington County communities including Hillsboro, Tualatin, and Sherwood. For active leaks causing flooding or water damage, we treat the call as an emergency and prioritize dispatch. Call (503) 974-3329 day or night and we will route the closest available technician to your location.

Yes. We hold current Oregon CCB (Construction Contractors Board) registration and Oregon plumbing license. Oregon requires both for any plumbing leak repair work on residential and commercial properties. We never fabricate license numbers, call (503) 974-3329 and we can provide current license documentation for any job.
