Repiping in Raleigh, NC

Which Raleigh homes are most likely to need it

Raleigh's housing is newer than in many North Carolina cities. Census survey data puts the median build year at 1997, and about 23% of homes date from before 1980. That older share is concentrated in in-town neighborhoods such as Historic Oakwood and Boylan Heights, where original galvanized steel supply lines may still be in the walls. Homes built from the late 1970s into the mid-1990s may have polybutylene, a gray plastic pipe with a poor track record.

Raleigh's water is not the usual culprit. The City's 2025 water quality report puts average hardness at about 25 ppm, which is soft, so scale buildup inside pipes is a minor concern. Pipe age, material and workmanship matter far more.

Signs it is time

• Two or more leaks in different spots over a few years
• Brown or rusty water from several fixtures, on both hot and cold
• Pressure that is weak throughout the house even though the city supply is normal
• Visible corrosion, green crust or pinhole leaks on exposed pipe

PEX compared with copper

PEX is the common pick for repipes now, though copper is still a good material. Ask the plumber to explain the choice for your house.

How the work goes

In a crawl space home, most new pipe runs underneath, with short drops into each wall, so drywall repair stays limited. Slab homes usually get new lines through the attic. Water is typically shut off for part of each workday rather than the whole job. Trade permits are filed through the City of Raleigh's Permit and Development Portal, and the plumber normally takes care of it.

What affects the cost

Bathroom and fixture count, total pipe length, crawl space or slab access, material choice and wall patching all affect the price. Get a written scope that states whether drywall repair is included, and ask how many days the water will be off so you can plan around it.
