An inspection flagged polybutylene
Gray plastic supply pipe in a house built from the late 1970s to the mid-90s can stall a sale or a policy. You need a scope and a number before the due-diligence period ends.
Buying a house with polybutylene →The 1950s and 60s ranch, the 80s split-level with gray polybutylene, the 90s townhome: each era of Charlotte house hid a different supply pipe. Level Repiping Charlotte replaces the whole run with PEX or copper through licensed and insured contractors, on a crawl space or a slab.

What brought you here
Gray plastic supply pipe in a house built from the late 1970s to the mid-90s can stall a sale or a policy. You need a scope and a number before the due-diligence period ends.
Buying a house with polybutylene →One pinhole is a repair. Several along the same copper line point to the pipe wall itself, and that is a question about the whole system.
Repipe or repair →Galvanized steel rusts from the inside and narrows as it goes, so the farthest fixtures lose flow first. Street pressure and valves can cause the same symptom, so they are checked too.
Low water pressure →A hot water leak under a slab can be opened and repaired, or bypassed by running new lines through the attic and walls. The floor and the pipe's age decide which.
Slab leak repair →Services

Why this approach
How it runs
The age of the house, the pipe you have seen, crawl space or slab, and what has been leaking.
Pipe material, fixture count, access routes and street pressure, written up as a scope with a price.
New lines are run, then connected to fixtures and the water heater, then pressure tested before walls are closed.
The permit office inspects the new piping; access openings in walls and ceilings are then patched to the agreed scope.

What it costs
Plumbers in the Charlotte metro earn a median $28.22 an hour, about 8% below the $30.67 national median (U.S. Bureau of Labor Statistics). A wage is not a billing rate: the billed rate also carries licensing, insurance, vehicles and overhead.
The real choice
| Spot repair | Partial repipe | Whole house repipe | |
|---|---|---|---|
| Fits when | One leak on pipe that is otherwise sound | One branch or the hot side is failing and the rest tests sound | Polybutylene, galvanized, or repeat leaks across the system |
| Openings | One | Along that run | Planned access across the house |
| Permit | Depends on the scope | Depends on the scope | Usually; confirmed with the permit office for each project |
| Old pipe left behind | All of the rest | Every run not replaced | None of the old supply pipe in use |

Mecklenburg plumbing permits issued between April 2025 and October 2026 describe a repipe. Polybutylene and PEX are named most often in their descriptions.
Questions
A whole house PEX repipe on a single-family home typically runs $4,000 to $12,000 or more in the Charlotte area. The number of bathrooms, the number of stories, slab versus crawl space and PEX versus copper move it most. Copper is quoted per house.
Usually. Mecklenburg County Code Enforcement issues plumbing permits for Charlotte and the six towns and inspects the new piping. North Carolina exempts some like-for-like replacements under $40,000 in a single-family home, so whether a particular repipe needs one is confirmed for each project.
Both are approved under the North Carolina Plumbing Code. Charlotte Water is soft and adds lime to raise its pH for corrosion control. PEX bends around long crawl space and attic runs with fewer joints; copper suits owners who want metal pipe and is quoted per house.
No code requires it. Insurers and buyers treat polybutylene differently, and the North Carolina Real Estate Commission tells buyer agents to have clients check with their insurer before making an offer, so check before a listing or an offer.
You do. Charlotte Water maintains the line to the meter. The shutoff, the line from the meter to the house and all of the piping inside belong to the owner, and leaks on that side are the owner's to repair.
Charlotte Water's service line inventory lists no lead service lines among more than 333,000 connections, and 66 galvanized lines that need replacing, mostly in older central neighborhoods.
Yes. New lines usually run through the attic and drop down inside interior walls to each fixture, which leaves the slab alone. Pipes in an attic need insulation under the North Carolina code.
Charlotte Water says pressure ranges from about 40 psi on high ground to more than 100 psi in low areas near creeks. Where pressure is above 80 psi, the county requires a pressure-reducing valve on new or remodeled plumbing.
Usually. Lines run along the floor joists below the house, so first-floor fixtures need fewer wall openings than in a slab house. Second-floor fixtures still need access through walls or ceilings.
Yes, as separate scopes. Drain and sewer lines are a different system from the water supply, gas lines are handled by contractors licensed for fuel piping, and the line from a well to the house is quoted on its own.
