Repiping a house in NoVA: what it costs, how long it takes, and when it's worth it

Your pipes have sprung their third leak this year, and you're looking at another water-stained ceiling. Three leaks in a year usually means the problem is the pipe itself, not one bad joint.

A full repipe makes sense for polybutylene, for galvanized steel that runs rusty, and for copper with repeat pinhole leaks. Most repipes take 2 to 5 days, and the cost is driven by your home's size, access, drywall repair, and permits. Here's how to tell which camp you're in.

Repipe or repair?

A repipe is usually the right call if you have:

• Polybutylene pipe (installed 1978 to 1995): gray plastic pipe that breaks down from the chlorine-based disinfectants in treated water and can leak without warning. If your home was built in that window, have the pipes checked for polybutylene pipe replacement.
• Galvanized steel with rusty water: brown, red, or black water from the cold taps, and a shower that barely rinses shampoo. Those old pipes are choking your system.
• Repeat copper pinhole leaks: three or more pinholes usually means the copper is failing throughout. Water chemistry is a factor in copper pinhole leaks.
• Weak flow at several fixtures at once, not just one.

A spot repair is usually enough if:

• You have one leak in otherwise good copper pipe
• The leak is at a joint, fitting, or fixture, not in the pipe wall
• Your pressure is strong and the water runs clear
• The copper is relatively recent

When we make a repair, we'll show you the inside of the pipe we removed. If the walls look good, we'll tell you spot repairs are the right call. If you're on your third leak in two years, more are usually coming, and it's better to plan a repipe than face a burst pipe emergency that floods your basement.

If your home still has its original pipes, it's worth having them checked before the leaks start. Polybutylene-era homes are the first place we'd look.

What drives the cost of a repipe

• Home size and layout: more bathrooms and a more complex layout mean more pipe and more labor
• Access: finished basements, finished walls, and tight crawl spaces take more work
• Pipe material: PEX is our standard for Northern Virginia repipes
• Drywall repair: plan for patching wherever pipes run
• Permits and inspections: typically required across Northern Virginia

Access is the biggest variable. A home with an open basement ceiling and drywall is simpler than one with a finished basement and finished walls everywhere the pipes run. Pioneer gives a written, upfront quote before any work begins.

Why we repipe with PEX

PEX (cross-linked polyethylene) is flexible, so it routes around obstacles with fewer joints and fewer wall openings. It holds up well to chlorinated water, and it doesn't build up minerals inside the way galvanized steel does.

It's also more forgiving in a freeze than copper, which matters in our winters.

We've repiped homes originally plumbed with polybutylene, copper, and galvanized steel, and PEX has performed better than all of them in our climate and water. If you want the longer comparison, see our post on copper vs. PEX vs. CPVC. Our PEX repiping page covers the service itself.

How long a repipe takes

Most repipes take 2 to 5 days, depending on the size and layout of the home. The order of work looks like this:

1. Water shut off, walls opened, new lines run

2. Pressure testing on the new system

3. County inspection before the walls are closed

4. Drywall patching and cleanup

You'll be without water during working hours, but we restore service each evening so you can shower and cook dinner.

If you're already opening walls for a renovation, do the repipe at the same time. Coordinating with your contractor means the walls only get opened once.
