Each insurer sets its own rules on polybutylene. Some write the policy, some ask questions, some decline. The answer that counts is your carrier's, in writing, and the paperwork from a repipe is what changes it.

Short answerPolybutylene insurance depends on the carrier. No North Carolina or South Carolina law requires polybutylene to be replaced, but each insurer decides whether to write or renew a policy on a house that has it and on what terms. Ask your own carrier in writing, before buying or renewing, and keep the permit and invoice if you repipe.
Polybutylene insurance is a question that comes up at two moments: when a buyer finds the gray pipe during due diligence, and when an owner’s carrier asks about the plumbing at renewal. Level Repiping Charlotte arranges polybutylene pipe replacement across Charlotte and the surrounding counties through licensed and insured contractors, and the insurer’s answer is often what sets the timeline. This guide explains why insurers care, what they may decide, and what to ask.
Homeowners insurance pays for sudden damage. A polybutylene fitting that lets go inside a wall or a ceiling can soak framing, insulation, drywall and floors before anyone notices, and that kind of claim is what carriers worry about. Polybutylene was installed in many houses from the late 1970s to the mid-1990s and has a long record of fitting and pipe failures, so many insurers treat it as a known risk.
How they act on that is up to each carrier. There is no single industry rule and no North Carolina or South Carolina law requiring replacement.
Homeowners in Charlotte and around North Carolina describe a range of answers. In one Charlotte discussion, an agent told a buyer that many homeowner policies would not cover polybutylene; another owner said they had to ask specifically to make sure it was covered, and that not every company would. Others report their insurer didn’t care. Buyers elsewhere report sellers being asked for credits on the grounds that a house with polybutylene would be hard to insure, and sellers pushing back.
None of that tells you what your carrier will do. It does tell you to ask before relying on an answer.
The North Carolina Real Estate Commission suggests buyers discuss polybutylene with their insurer before making an offer. Whether you are buying or renewing, ask:

Many homeowners policies separate two costs. Water damage from a sudden leak, to ceilings, walls and floors, is the kind of loss policies are usually written to cover. The cost of replacing the pipe that failed, and damage from a slow leak over time, is often treated as maintenance or wear and left to the owner. Policies vary, and the wording in yours decides. The repiping insurance guide goes into what policies typically cover and what a repipe can change.
The class-action settlement that once paid for polybutylene replacements is no longer a source of money. Homeowners report its claim windows closed years ago.
If a repipe is what the carrier wants, the documents matter as much as the work:
A partial repipe leaves some polybutylene in service. Tell the carrier exactly what was replaced; a partial job described as a full one is a problem at claim time.
When a carrier sets a deadline, the assessment and written scope come first, then scheduling. Most families stay in the house during a repipe. A whole house PEX repipe on a single-family home typically runs $4,000 to $12,000 or more in the Charlotte area; larger, two-story and slab homes run higher. The repipe cost guide explains what moves it.
If you are buying, the guide to buying a house with polybutylene covers the due-diligence side. If you aren’t sure the pipe is polybutylene, start with the pipe identification guide.
If your carrier has asked about the pipe, call (704) 452-4386 and have the letter or email at hand.
Questions
Many applications ask about the age and type of plumbing, and some carriers ask about polybutylene by name. An inspection report from a purchase may also reach the insurer. Answer accurately: a misstatement on an application can cause trouble later with a claim. If you don't know the material, find out before you apply.
Yes. Carriers set their own underwriting rules, so a decline from one does not mean every carrier will decline. An independent agent who works with several carriers can ask on your behalf. Get each answer in writing, with any conditions, such as a deadline to replace the pipe.
The North Carolina Department of Insurance regulates insurers doing business in North Carolina and handles consumer questions and complaints about them. In South Carolina the state Department of Insurance does the same. Neither sets a rule that polybutylene must be replaced; underwriting decisions are each insurer's.

Polybutylene usually turns up in the inspection report, partway through due diligence, with an offer already on the table. Here is what to confirm, who to call, and how buyers handle it, in the order the clock allows.
A policy usually pays for the damage a sudden leak causes, not for replacing the old pipe. Where a repipe helps is with the insurer's view of the house, and that depends on the carrier.
Five supply pipes turn up in Charlotte-area houses. Color, joints, markings and a magnet tell most of them apart in a few minutes, as long as you look in more than one place.
