Repiping
When leaks keep showing up in different spots or water pressure has dropped throughout the whole house, the pipes themselves are usually the problem, not any one fixture.

How Do You Know You Need Repiping Instead of a Repair?
Repiping means replacing a significant portion, or all, of a home’s water supply lines, typically with copper or PEX, rather than continuing to patch individual leaks as they appear. It becomes the right call when the pipe material itself is failing systemically: galvanized steel pipes corroding from the inside, polybutylene pipe from the 1980s and 90s known for brittle failure, or copper that’s simply reached the end of its expected lifespan. The tell is usually pattern, not severity, one leak is a repair, but leaks appearing in new locations every few months, water pressure that’s dropped house-wide rather than at one fixture, or water that’s consistently discolored, all point to a system-wide problem that repiping fixes at the source. It’s a bigger job than a typical repair, but it also means no more repeat service calls for the same underlying issue.
You can only patch aging pipe so many times before patching becomes the expensive option.
Signs You Need Repiping
These signs point to the plumbing system itself, not just one bad fitting.
- Leaks appearing in different locations every few months
- Water pressure that’s dropped throughout the entire house, not just one fixture
- Consistently discolored or rust-tinted water from multiple taps
- Visible corrosion on exposed pipes in the garage, crawlspace, or basement
- A home over 40 to 50 years old that’s never had the supply lines replaced
What You Can Check Before Requesting Quotes
Repiping itself is licensed plumbing work from start to finish, but a little information upfront helps plumbers scope the job accurately.
- Check the approximate age of your home and whether the original pipes have ever been replaced
- Look at any exposed pipe in the garage, attic, or under sinks and note the material if you can identify it
- Track how many separate leaks you’ve had repaired over the past year or two
- Note whether low pressure affects the whole house or just specific fixtures
- Don’t attempt to replace supply lines yourself, this involves cutting into walls and requires licensed, code-compliant work

Frequently Asked Questions About Repiping
How much does repiping a house cost?

Most whole-home repiping jobs take three to five days, depending on house size and how much wall or ceiling access is needed.
