Water Line Replacement – Beaverton, OR
Beaverton's housing stock covers more than six decades of construction — from 1950s and 60s homes near downtown and Cedar Hills to 1990s and 2000s subdivisions in Bethany. The water service lines running through the yards of those homes are just as varied: galvanized steel in the oldest areas, copper in the middle-era neighborhoods, and newer PEX installations in the most recent builds. What they have in common is that once a service line fails underground, it fails slowly and expensively — rising water bills, lost pressure, and a yard problem that doesn't go away until the line does.
What's in the Ground Depends on When Your Street Was Built
Service line problems in Beaverton aren't random — they follow construction eras. Knowing what material is in the ground gives you a clear picture of what to expect and when to act.
Downtown / Cedar Hills — Galvanized
Galvanized steel was the standard service line material through the 1960s. After 60-plus years, interior mineral deposits narrow the pipe, pressure drops, and corrosion can discolor the water. These lines are at or past end-of-life throughout the older Cedar Hills and downtown Beaverton areas.
Oak Hills / Mid-Era — Copper
Copper service lines in the 1970s and 80s were an improvement over galvanized — but the soft, mildly acidic water throughout the Portland metro causes pitting corrosion in copper over decades. Homes from this era in Oak Hills and similar neighborhoods are now 40 to 55 years old, which puts them in the pinhole leak window.
Bethany / Newer Builds — Copper or Early PEX
Bethany hillside homes from the 1990s and early 2000s have copper or early PEX service lines. At 25 to 35 years old, copper in this era is approaching the age where soft-water pitting corrosion begins showing up. Early PEX is generally still in good shape structurally but worth knowing about.
Underground Leaks — Easy to Miss
Service line leaks often go unnoticed for months. The water doesn't appear inside the house — it goes into the soil. A gradually rising water bill, a soft yard patch, or dropping pressure are the signals. By the time something is obviously wrong, the leak has often been running for a while.
Aging Pipe vs. New PEX
Aging Galvanized or Copper Line
- Galvanized: interior rust narrows diameter, drops pressure
- Copper: soft-water pitting leads to pinhole leaks
- Underground leaks often invisible for months
- Repair addresses one failure point — more follow
- Discolored water from galvanized corrosion
New PEX Service Line
- Unaffected by soft water chemistry or mineral buildup
- No pitting, no corrosion, no interior narrowing
- Full pressure restored from day one
- Flexible — handles soil movement and root pressure
- 50+ year rated lifespan
Signs Your Beaverton Water Line Needs Attention
- Water bill increasing without an obvious explanation
- Soft, wet, or unusually green patch of yard over the line route
- Pressure that's dropped noticeably at multiple fixtures
- Rust-colored or discolored water (galvanized corrosion)
- Sound of running water when all fixtures are off
- Home is 40+ years old with original service line and no replacement history
Directional Drilling Throughout Beaverton
Beaverton's lot patterns vary by era — flat through Cedar Hills and the mid-era neighborhoods, graded hillside in Bethany and the outer areas. Most of those lots work well for directional drilling, which pulls the new PEX line underground without opening a continuous trench. The driveway stays intact, trees and landscaping along the route aren't disturbed, and the yard is largely undisturbed when we finish.
Where site conditions require traditional excavation — unusual routing, hardscape, or other constraints — we explain why and walk you through the plan before we start. Most Beaverton water line jobs are completed in one day with water restored before we leave.
- Directional drilling where lot and soil allow
- Traditional excavation when routing requires it
- New PEX service line rated 50+ years
- Washington County permit handled
- Water restored before we leave
- Most jobs completed in one day
Frequently Asked Questions
My Beaverton home has galvanized lines from the 60s. When should I replace?
Galvanized steel service lines from the 1960s are 60-plus years old — well past their designed service life. Even if you haven't seen obvious symptoms yet, reduced pressure, mineral buildup inside the pipe, and corrosion risk are present. The question at that age is usually when to replace, not whether. If the water bill has crept up or pressure is noticeably lower than it used to be, now is the right time.
My water bill went up but I can't find a leak inside. What's happening?
Turn off all fixtures and check whether your water meter is still moving. If it is, there's a leak somewhere in the service line between the meter and the house — it's going into the soil, not showing up inside. In a Beaverton home with copper from the 1970s or 80s, that's a pinhole leak in the underground line. Call us before it gets worse; an underground leak that's been running will eventually saturate the soil and cause a larger problem.
Do you handle the Washington County permit for water line work?
Yes — we handle the permit. You don't need to coordinate with the county. We pull the permit, schedule any required inspections, and handle the paperwork as part of the job.
