What is Repiping?

Repiping is the replacement of a home's water supply lines, either whole-house or by section, typically when original piping is failing or problem-prone. Common triggers include aging galvanized steel that corrodes and restricts flow internally, gray polybutylene supply lines known for leaks, repeated pinhole leaks, discolored water, and persistently low pressure. Replacement usually uses PEX or copper.

Why it matters to you

Much of the Lowcountry's housing stock is older, and supply lines running through humid crawlspaces carry decades of history — when leaks start repeating, patching one spot at a time can cost more than replacing the system.

Practical guidance

If you've had more than one leak in a short span, have discolored water, or know your home has polybutylene or galvanized lines, ask for a full piping assessment before the next emergency. Homes over crawlspaces are often easier to repipe with less wall and floor disruption.
