Asheville and the surrounding WNC communities are full of beautiful older homes with real character. From historic Montford bungalows to mid-century ranches tucked into the mountainsides, the housing stock in this area is one of the things that makes it special. But that character often comes with a catch: aging plumbing systems that may be nearing the end of their useful life.
If your home was built before the 1990s, there's a reasonable chance the original pipes are still doing the heavy lifting. And while plumbing is built to last, it doesn't last forever. Knowing the warning signs of failing pipes can save you from unexpected water damage, costly repairs, and the headaches that come with plumbing you can't rely on.
Whole-house repiping might sound like a big undertaking, and it is a significant project. But for many Asheville-area homeowners, it's also one of the smartest long-term investments they can make. Here's how to know if your home is telling you it's time.
Quick Summary:
- Homes built before the 1990s may still have original plumbing that's nearing the end of its lifespan
- Warning signs include discolored water, frequent leaks, low water pressure, and visible pipe corrosion
- Common pipe materials in older WNC homes (galvanized steel, polybutylene) are known to deteriorate over time
- Repiping during a remodel is the most cost-effective approach since walls are already open
- A full repipe protects your home's value, your water quality, and your peace of mind
What Is Whole-House Repiping?
Whole-house repiping is exactly what it sounds like: replacing all or most of the water supply pipes in your home with new materials. This typically means removing the old pipes and installing new ones, most commonly copper or PEX (cross-linked polyethylene), throughout the house.
The process involves accessing pipes inside walls, ceilings, crawl spaces, and sometimes floors. A professional plumbing team will plan the most efficient route for the new pipes, complete the installation, and then restore access points. The scope depends on the size of your home and the complexity of your existing plumbing layout.
It's not a weekend project, and it's not something homeowners should attempt on their own. But with an experienced team, the process is well-organized and designed to minimize disruption to your daily routine. Barlow Plumbing has extensive experience with whole-house repiping across the Asheville area and can walk you through exactly what to expect for your specific home.
5 Warning Signs Your Home May Need Repiping
Your plumbing system usually gives you plenty of signals before it fails completely. The key is knowing what to look for and taking those signals seriously rather than patching problems one at a time.
1. Discolored Water
If the water coming from your taps has a brown, yellow, or reddish tint, that's rust and sediment from corroding pipes. You might notice it most when you first turn on a faucet in the morning or after the water has been sitting in the pipes for a while. Occasional discoloration after utility work is normal, but persistent discolored water coming from your own plumbing is cause for concern.
2. Frequent Leaks in Multiple Locations
One leak might be a bad fitting or a localized issue. But when you're repairing leaks in the kitchen one month and the bathroom the next, it's a sign that the pipe material itself is deteriorating throughout the house. At some point, patching individual leaks becomes more expensive than replacing the system.
3. Low Water Pressure Throughout the House
Low water pressure can have several causes, but one of the most common in older homes is pipe corrosion. As pipes corrode from the inside, mineral deposits and rust narrow the interior diameter, restricting water flow. If your water pressure has gradually declined over the years and isn't related to a municipal supply issue, your pipes may be closing up from the inside.
4. Visible Pipe Corrosion
This is the most straightforward sign. If you can see exposed pipes in your basement, crawl space, or utility areas, take a close look. Green discoloration on copper pipes, flaking or dimpling on galvanized pipes, and any visible pinholes or wet spots are all signs of advanced deterioration.
5. Metallic-Tasting or Metallic-Smelling Water
Water that has a noticeable metallic taste even after running the tap indicates the pipe material is likely leaching into your water supply. This is more than an inconvenience: it's a water quality concern that a quality water filtration system can help address in the short term, but repiping solves at the source.
Common Pipe Materials in Older Asheville Homes
Understanding what type of pipes you have is an important part of evaluating whether repiping is in your future. Here are the most common materials found in WNC homes and what each one means for homeowners.
Galvanized Steel
Galvanized steel was the standard in homes built from the early 1900s through the 1960s. These pipes are steel coated with a layer of zinc to prevent rust, but that zinc coating wears away over time. Once it does, the steel underneath corrodes, narrowing the pipe interior and contaminating the water. Galvanized pipes have a typical lifespan of 40 to 70 years, which means many in the Asheville area are well past their prime. If your home has galvanized pipes, repiping is generally not a question of "if" but "when."
Polybutylene
Polybutylene (poly B) pipes were widely used from the late 1970s through the mid-1990s. They were marketed as an affordable alternative to copper, but they turned out to be a problem. Polybutylene reacts with chlorine and other oxidants in municipal water supplies, becoming brittle and prone to cracking and failure over time. These pipes are notorious for failing without warning, and most plumbing professionals strongly recommend replacing them. If your home was built during this era, it's worth checking what's in your walls.
Copper
Copper pipes have been a reliable standard for decades and can last 50 years or more with good water conditions. However, copper is not immune to problems. Acidic water, which can occur in some WNC areas with well water, can accelerate corrosion. Pinhole leaks in copper are a known issue in certain regions. If your copper pipes are older and you're experiencing pinhole leaks, repiping with modern materials may be the best path forward.
PEX (Cross-Linked Polyethylene)
PEX is the most common material used in modern repiping projects. It's flexible, resistant to corrosion and scale buildup, and performs well in the temperature extremes that WNC mountain homes experience. PEX is typically more affordable to install than copper because its flexibility requires fewer fittings and allows for faster installation.
What to Expect During the Repiping Process
One of the biggest concerns homeowners have about repiping is the disruption to their daily life. It's a fair concern, and a good plumbing team will be upfront about what's involved.
The timeline for a whole-house repipe typically ranges from a few days to about a week, depending on the size and layout of your home. A single-story ranch with an accessible crawl space will go faster than a multi-story historic home with plaster walls and limited access points. Your plumber should be able to give you a realistic timeline after evaluating your specific situation.
During the process, there will be periods when your water supply is shut off, but an experienced team works to minimize this. Most of the work involves accessing pipe routes through walls, ceilings, and crawl spaces, running the new pipe, and then patching access points. Barlow Plumbing works carefully to keep the impact on your home as contained as possible and cleans up as the job progresses.
After the repipe is complete, you'll likely notice an immediate improvement in water pressure and water quality. Many homeowners say the difference is striking, especially if they'd been living with gradually declining performance and didn't realize how much they'd been compensating.
Repiping During a Remodel: Why It Makes Sense
If you're planning a kitchen or bathroom remodel, or a home addition, it's worth having a serious conversation about repiping at the same time. The reason is simple: the most labor-intensive and expensive part of repiping is accessing the pipes inside your walls. When those walls are already open for a remodel, you eliminate a significant portion of the cost and disruption.
This is especially relevant in the Asheville area, where many homeowners are renovating older homes. If you're gutting a bathroom down to the studs or reconfiguring a kitchen layout, your contractor is already exposing the plumbing. Adding a repipe to the scope of work at that stage is far more efficient than doing it as a separate project later.
Even if your current remodel only involves one section of the house, it's a good opportunity to assess the condition of the pipes you can see and make a plan for the rest of the home. Your plumber can evaluate the exposed pipes during the remodel and give you an honest assessment of how much life is left in the rest of the system.

How Repiping Protects Your Home's Value
A full repipe is an investment, and it's one that pays for itself in several ways.
The most immediate benefit is reliability. New pipes mean no more surprise leaks, no more worrying about water damage behind your walls, and no more gradually declining water pressure. You'll have consistent, clean water flow throughout your home, and you won't be calling a plumber every few months to patch another failing section.
From a real estate perspective, repiping is a significant selling point. Buyers and home inspectors pay close attention to plumbing condition, and a home with new pipes is far more attractive than one with aging galvanized or polybutylene systems. In Asheville's competitive housing market, outdated plumbing can stall a sale or lead to lower offers after inspection.
There's also the insurance angle. Some insurance companies are increasingly cautious about covering homes with known problem pipe materials like polybutylene. A repipe can simplify your coverage and reduce your risk profile.
Most importantly, repiping gives you peace of mind. You're not wondering when the next leak will appear or whether that discolored water is getting worse. You know your plumbing system is solid, and you can focus on everything else that makes your home worth living in.
Frequently Asked Questions
How long does whole-house repiping take?
For most residential homes in the Asheville area, a full repipe takes between three and five days. Larger homes, multi-story layouts, or homes with limited access to pipe routes may take up to a week. Your plumber will provide a specific timeline after evaluating your home. During the process, water shutoffs are kept as brief as possible.
Will repiping improve my water pressure?
In most cases, yes. If your low water pressure is caused by corroded or mineral-clogged pipes, which is very common in older homes, new pipes will restore full water flow. The improvement can be dramatic, especially if the old pipes had decades of buildup narrowing the interior diameter. If low pressure persists after repiping, the issue may be on the municipal supply side.
How do I know what type of pipes I have?
The easiest way to check is to look at exposed pipes in your basement, crawl space, or utility room. Galvanized steel pipes are typically dull gray and may show rust or corrosion. Copper pipes have a distinctive copper color that may have turned green in places. Polybutylene pipes are usually gray, white, or blue plastic. PEX piping is flexible plastic, often red (hot) and blue (cold). If you're not sure, any licensed plumber can identify your pipe materials during a routine visit.
Is It Time for Your Home?
If you've been noticing the warning signs, or if you know your home has aging pipes that are past their expected lifespan, repiping is worth a closer look. It's one of those projects that's easy to put off but gets more expensive and more urgent the longer you wait.
