Whole-Home PEX Replacement in Portland, ME
PEX-A is the most common replacement for polybutylene because it is flexible, scale resistant and easy to route. We use Uponor PEX-A with expansion fittings that do not restrict flow. New lines run from the main shutoff to every fixture, water heater and appliance. Most homes are completed in two to four days.

Insurance and Home Sale Documentation in Portland
Some insurers decline or surcharge policies on homes with polybutylene. Buyers and lenders may also ask about it during inspections. After replacement we provide permit records, invoices and photos showing the new system. That paperwork helps with insurance renewals and real estate transactions.
Copper Repiping Solutions in Portland, ME
For homeowners in Portland, ME who prefer traditional materials, we also offer full polybutylene pipe replacement with copper. Copper piping is known for its longevity, resistance to bacterial growth, and proven track record. While more rigid than PEX, modern copper installations are highly durable and provide excellent water pressure. Our plumbers are skilled in careful copper soldering and installation, creating a robust and reliable plumbing system that will last for decades, often outliving the home itself when properly maintained.
Polybutylene Identification and Inspection in Portland
Polybutylene is usually gray, though it can be white, blue or black, and is often stamped PB2110. You may see it at the water heater, under sinks or near the main shutoff. We inspect visible lines, check the stamps and trace runs through the attic. You get a clear answer and a written replacement estimate.

We provide detailed, upfront estimates after a careful inspection.
