Repiping in Gresham
Polybutylene Pipe Failures in Gresham’s 1980s Subdivisions
Gresham experienced a significant building boom during the early-to-mid 1980s, and a substantial number of homes from that era — particularly in the neighborhoods east of Burnside Road and south of Powell Boulevard — were plumbed with polybutylene supply lines. Polybutylene was the budget-friendly pipe material of its decade: flexible, inexpensive, and fast for builders to install. The problem is that chlorine in Gresham’s municipal water supply degrades polybutylene from the inside, creating micro-fractures that grow invisibly through the pipe wall. A pipe that appears perfectly sound from the outside can split along its full length without warning, flooding a room in minutes and saturating crawl spaces in hours.
The danger with polybutylene is the absence of warning signs. Unlike galvanized pipe, which telegraphs its deterioration through gradually declining water pressure and rusty water, polybutylene looks and feels normal right up until the moment it fails. Home insurance claims from polybutylene failures are among the most expensive residential water damage events we see in Gresham. Proactive repiping with PEX eliminates the risk entirely — and at a cost that is a small fraction of what a catastrophic poly-B failure and the resulting water damage restoration would total. We can repipe a typical Gresham ranch home in a single day.

Copper Pinhole Leaks in Gresham’s Centennial and Rockwood
Gresham’s Centennial neighborhood and portions of Rockwood contain a high concentration of ranch and split-level homes from the 1960s and 1970s that were plumbed with copper supply lines. At 50 to 60 years of age, these copper systems are developing pinhole leaks — tiny perforations caused by internal pitting corrosion that eats through the pipe wall from the inside. Pinhole leaks tend to appear first at elbows and tee fittings where turbulent water flow accelerates the corrosion process, and they concentrate on hot water lines where higher temperatures speed the chemical reaction between copper and dissolved minerals.
A single pinhole leak in a Centennial home can be patched in an hour. The second leak, appearing a few months later in a different room, is the signal that the corrosion is systemic — every copper joint in the house is aging at roughly the same rate, and more leaks will follow on a tightening schedule. At this point, continuing to patch individual leaks becomes more expensive over time than replacing the entire system at once. PEX repiping in Gresham’s ranch-style homes is efficient because the single-story layout and accessible crawl spaces allow our team to route new lines with minimal wall openings. The result is a home with brand-new supply plumbing, zero leak risk, and water pressure restored to what these homes delivered when they were new.

PEX Repiping and Freeze Protection in Gresham
Gresham sits at a slightly higher elevation than central Portland and is more exposed to cold east wind events that push through the Columbia Gorge corridor. While Gresham does not experience the extreme Gorge winds that Troutdale faces, the city sees enough winter cold to make freeze protection a legitimate consideration for any home with pipes in crawl spaces, exterior walls, or unheated garages. Copper and galvanized pipe are rigid materials that crack when frozen water expands inside them — a burst copper line in an exterior wall can release gallons of water into the wall cavity before anyone realizes what has happened.
PEX’s molecular structure allows it to expand slightly under the pressure of freezing water without rupturing. This is not a guarantee against freeze damage — a prolonged hard freeze can still overwhelm PEX — but it provides a meaningful safety margin that rigid pipe materials simply do not have. For Gresham homeowners repiping from copper or galvanized, the switch to PEX delivers both a corrosion-free supply system and an inherent resistance to the freeze events that occasionally test homes in Gresham’s Pleasant Valley and Powell Valley neighborhoods. Combined with proper crawl space insulation and frost-proof hose bibs, a PEX repipe positions the home to handle whatever winter brings.

Gresham Repiping: Process, Timeline, and What It Costs
A whole-house repipe in Gresham follows a straightforward process. It begins with an in-home assessment where our plumber maps the existing system, identifies the pipe material and condition, measures water pressure, and plans the routing for the new PEX lines. For a typical three-bedroom Gresham home with two bathrooms, the installation takes two days. Larger homes in Pleasant Valley or Powell Valley with three or more bathrooms and finished basements may take three days. Water is turned off during work hours and restored each evening.
Gresham repiping costs range from $4,000 to $8,000 for a standard PEX repipe, depending on the home’s size, number of fixtures, and accessibility. Copper repiping costs 20 to 40 percent more. These figures include all materials, labor, permits, inspections, and wall patching. We provide a written estimate after the in-home assessment — no surprises, no hidden fees, no charges that were not discussed upfront. Financing options are available for Gresham homeowners who want to address their pipe system now without paying the full amount out of pocket.

Repiping in Gresham — Common Questions
If your 1980s Gresham home has polybutylene supply pipes, repiping is strongly recommended. Polybutylene is prone to sudden failure at fittings and connections, and the risk increases as the material ages. Even if you have not experienced a leak yet, proactive replacement prevents potential water damage and protects your home’s value.
PEX is the most popular choice for Gresham repiping projects because it offers excellent durability, flexibility, and affordability. Copper is also an excellent option with a longer track record. Both materials work well in Gresham’s water conditions. Our technicians discuss the pros and cons of each during your consultation.
Polybutylene pipe is a flexible plastic pipe that is gray, blue-gray, or sometimes black in color. Look at exposed supply pipes near your water heater, in your crawl space, or at the water meter connection. Polybutylene fittings are typically copper or plastic crimp rings. If you are unsure, our technicians can identify the material during an inspection.
