Whole House Repiping and Polybutylene Replacement

How much does whole house repiping cost in the Carolinas?

Published local ranges for a polybutylene to PEX repipe run from about $3,500 to $12,000, driven by square footage, number of bathrooms and wall access.

If your home was built in the late 1970s through the mid 1990s, there is a real chance it has polybutylene supply pipe. If it was built before that, it may have galvanized steel that is rusting from the inside.

Repiping is a big job, so we walk the house, map the system and give you a written scope before you commit.

What is different about the Carolinas

Polybutylene was widely used in subdivisions across the Carolinas during the late 1970s through the mid 1990s, so it shows up in a lot of Raleigh, Cary, Charlotte and Rock Hill neighborhoods. Older in town homes in Myers Park, Dilworth, Oakwood and Trinity Park may still carry galvanized lines.
