Why Some Homeowners Still Choose Copper
Copper has been a standard plumbing material for decades because it’s durable, resistant to bacterial growth, and holds up well over a long lifespan, which is why many homeowners specifically request it during a repipe even though it costs more upfront than PEX. It’s a solid, proven choice, particularly for homeowners planning to stay in their home long-term.
Copper pipe installed decades ago is often still going strong today, that track record counts for something.
When Copper Repiping Is Worth Considering
These situations often lead homeowners toward copper specifically.
- You’re planning to stay in your home long-term and want a proven, durable material
- Your home’s existing supply lines are aging galvanized steel or corroded copper
- You have concerns about plastic piping materials leaching into water
- You want a plumbing material with a long, well-documented performance history
- A previous repipe quote left you deciding between copper and PEX
What to Ask Before Getting a Copper Repiping Quote
This is licensed-only, whole-house work, but the right questions help you compare fairly.
- Ask about the copper pipe grade (Type L is common for residential supply lines)
- Confirm whether wall repair after installation is included
- Ask how copper pricing compares to PEX for your specific project
- Get a clear timeline, since soldering copper joints takes more time than PEX connections
Why Compare Quotes Instead of Calling Just One Plumber
Here’s what matters when comparing copper repiping quotes:
- Matched with licensed, insured plumbers experienced specifically with copper installation
- Compare pricing, since copper typically costs more in materials and labor than PEX
- Free to use, with zero obligation to hire anyone you're matched with
Copper is a proven, long-lasting choice for homeowners who want it. Comparing quotes helps you see the real cost difference against PEX for your specific home.

Everything You Need to Know About Copper Repiping.
Why do homeowners still choose copper for repiping?
Copper has been used for water lines for decades because it’s rigid, resists bacterial growth, tolerates high temperatures, and holds up well over a very long service life. It’s a common choice for homeowners doing a full repiping project who want a material with a long, proven track record. The tradeoff is a higher material and labor cost compared to PEX, since copper requires soldered or pressed joints rather than quick push-fit connections.
How much does copper repiping cost compared to PEX?
Copper repiping generally costs more than PEX repiping for the same home, largely because copper material prices fluctuate with commodity markets and installation takes longer due to soldering each joint. The exact gap depends on current copper prices and your local labor rates, so it’s worth getting quotes for both materials before deciding. Some homeowners choose a hybrid approach, using copper for exposed or visible runs and PEX in walls, though this should be discussed with your plumber. If you’d like more background, our whole-home repiping project page covers related options in more detail.
Does copper pipe ever fail or develop leaks?
Yes, copper can develop pinhole leaks over time, especially in areas with acidic or highly mineralized water that gradually corrodes the pipe wall from the inside. This is different from the widespread failure seen in galvanized steel, but it’s still worth having leak detection done periodically if your home has older copper. If a pattern of repeated pinhole leaks shows up, it may be time to consider full whole-home repiping rather than continuing to patch individual leaks.
How long does copper piping typically last?
Copper piping commonly lasts 50 years or more under normal water conditions, making it one of the longer-lived plumbing materials available. Its lifespan can be shortened by aggressive water chemistry, so homes with unusually acidic or soft water may see earlier pinhole leaks. A water quality test can help determine whether your water conditions are likely to shorten copper’s expected lifespan. If you’d like more background, our PEX alternative page covers related options in more detail.
Is copper repiping noisy or prone to water hammer?
Copper can transmit a banging or knocking sound known as water hammer if pipes aren’t properly secured or if there’s no cushioning at fixture shutoffs, though this is a workmanship issue rather than a flaw in the material itself. A well-installed copper system with properly strapped pipes and, where needed, water hammer arrestors should run quietly. If you’re hearing banging after a copper repipe, ask your plumber to check the pipe strapping and consider whether a pressure regulator adjustment would help. If you’d like more background, our plumbing inspection page covers related options in more detail.
Can copper pipe be used with any water heater or fixture?
Copper is compatible with virtually all standard water heaters and fixtures, including tankless water heaters, since it handles higher temperatures well. It’s a reliable choice when connecting to a variety of fixture types without needing special adapters. Just be cautious about mixing copper directly with galvanized steel fittings, since that combination can accelerate corrosion at the joint. If you’d like more background, our full services list page covers related options in more detail.
How long does a copper repiping project take?
Because copper requires cutting, fitting, and soldering each joint, a copper repipe generally takes a bit longer than an equivalent PEX job, often three to five days for an average single-family home. Homes with more bathrooms, multiple stories, or difficult attic and wall access will take longer. Ask your plumber for a day-by-day schedule so you know when water will be interrupted in each part of the house. You can also compare this against whole-home repiping project and PEX alternative to see which fits your situation.
Is copper repiping a good long-term investment for an older home?
For homeowners planning to stay long-term, copper’s decades-long lifespan and resale reputation often make the higher upfront cost worthwhile, especially when replacing failing galvanized pipe. It also removes the corrosion and rust-colored water issues common with old galvanized steel systems. If budget is the primary concern rather than resale value, PEX offers similar reliability at a lower cost. If you’d like more background, our plumbing inspection page covers related options in more detail.
Do I need a permit for copper repiping?
Yes, replacing a home’s water supply piping with new copper typically requires a permit and inspection in most cities and counties, the same as any other whole-home repiping material. A licensed plumber will usually handle this paperwork as part of the project scope. Permit and inspection timelines can vary, so ask your contractor about typical turnaround in your specific city or county. It’s also worth reviewing full services list if you’re weighing this against other options, and whole-home repiping project for a wider view.
What's the environmental and recycling angle on copper pipe?
Copper is fully recyclable and retains scrap value, which is one reason old copper removed during a repipe is often hauled away and recycled rather than sent to a landfill. It’s also a naturally occurring material without the plastic content found in PEX, which some homeowners prefer for personal preference reasons. If sustainability is a deciding factor for you, ask your plumber how they handle removed pipe and whether locally sourced copper is available. See PEX alternative for a closer look at that option, and our plumbing inspection for everything else we cover.
Frequently Asked Questions
Is copper more expensive than PEX?

How long does copper piping typically last?
Well-installed copper piping can last 50 years or more, which is part of its appeal.
Does copper have any downsides compared to PEX?
It’s more rigid and time-consuming to install, and in some water conditions can be more prone to pinhole leaks over many decades.
Can copper and PEX be mixed in the same repipe?
Yes, some homeowners choose copper for exposed or high-traffic areas and PEX elsewhere, though a plumber can advise on the best approach.
Is copper repiping noisier during installation?
It can involve more cutting and soldering work, which may be somewhat more disruptive than a PEX installation.
Is comparing quotes free?
Yes, with no obligation to hire anyone you’re matched with.
