Old galvanized pipes don’t fail all at once. They corrode slowly, restrict water flow, and spring small leaks — until one day the damage is impossible to ignore. By then, waiting has already made the situation far worse than acting early would have. Whole house repiping is the solution that stops that cycle for good.
At Pike Plumbing & Sewer, our team, including Anthony Estrella, Corey Moline, Maxx, and Deven, has completed this type of work across King, Pierce, and Snohomish Counties. With 30+ years of combined plumbing experience, we’ve seen what happens when homeowners wait too long — and what a properly repiped home looks like when the job is done right. Whole house repiping is the largest project within our piping and repiping services.
What Is Whole House Repiping?
Whole house repiping is the complete replacement of a home’s existing water supply pipes with new piping material. Rather than patching individual leaks or replacing one section at a time, repiping addresses the entire supply system in a single, coordinated project.
This is not a minor repair. It’s a planned renovation of the plumbing infrastructure that runs behind your walls, under your floors, and through your crawlspace. When done correctly, it eliminates the root cause of recurring leaks, poor water pressure, and discolored water — problems that no amount of spot repairs will permanently fix.
Repiping for the Whole House: What the Process Actually Involves
A full repipe means accessing the existing supply lines throughout the home. That typically involves opening walls, working through crawlspaces, and routing new pipe to every fixture — sinks, showers, toilets, appliances, and outdoor connections.
The scope depends on the size of the home, how the pipes are routed, and what material is being replaced. Homes with galvanized steel pipes from the 1950s through 1980s are the most common candidates. Polybutylene pipe — a gray plastic material installed in many homes through the 1980s and 1990s — is another frequent driver of full repipes due to its known tendency to crack and fail.
Once the new lines are in place, drywall is patched, connections are tested, and the system is inspected before water is restored. A well-organized crew can complete most residential repipes with minimal disruption to the home’s occupants.
What Materials Are Used in a Repipe?
The two most common materials used in whole house repiping today are copper and PEX (cross-linked polyethylene).
| Material | Key Strengths | Common Use Cases |
|---|---|---|
| Copper | Long lifespan, heat-resistant, proven track record | Hot and cold supply lines, exposed applications |
| PEX | Flexible, freeze-resistant, easier to route through walls | Residential supply lines, crawlspace runs, retrofit projects |
Both materials are durable and often used together. Pike typically uses PEX for most supply runs and copper for stub-outs, with the exact mix based on the home’s layout and conditions.
A Full Replacement, Not Another Patch
Whole house repiping replaces your home’s entire water supply system — not just a section of it. The goal is a fresh start for your plumbing, not another temporary patch. If a single line has already split, our pipe burst repair team stops the damage first and then helps you decide whether the rest of the system should follow.
Repiping for the Whole House: Signs You Need It
Knowing when to repipe is half the battle. Your home’s plumbing will usually show clear warning signs before a major failure — if you know what to look for.
Recurring Leaks in Multiple Locations
One leak is a repair. Two or three leaks in different parts of the house within a short period is a pattern — and patterns point to systemic pipe deterioration. When the pipe material itself is failing, fixing individual joints and fittings is a temporary measure at best.
If your plumber has visited the same home multiple times in a year for water leak repair in different places, it’s time to have an honest conversation about whether a full repipe makes more sense than continued repairs.
Discolored or Rusty Water
Brown or reddish water coming from your taps is a direct sign of corroding pipes. Galvanized steel pipes rust from the inside out. As the corrosion progresses, it flakes into the water supply and eventually reduces the interior diameter of the pipe — cutting your water pressure along with your water quality.
This is not a water heater problem. If the discoloration appears in cold water lines as well as hot, the issue is almost certainly in the supply pipes themselves.
Consistently Low Water Pressure
Mineral buildup and corrosion inside aging pipes narrows the passageway water travels through. The result is noticeably reduced pressure at faucets and showerheads — pressure that doesn’t improve no matter how many fixtures you clean or replace.
If you’ve ruled out pressure regulator issues and your pressure is still weak throughout the house, the pipes themselves are likely the bottleneck. When the restriction is in the line between the street and the house, water line replacement may be the right fix instead of, or alongside, an interior repipe.
Pipes That Are Simply Old
Age alone is a legitimate reason to evaluate repiping. Galvanized steel pipes have a functional lifespan. Polybutylene pipes are considered a ticking clock by most plumbing professionals. If your home was built before 1985 and the original pipes have never been replaced, a plumbing inspection can tell you exactly what condition they’re in and what your realistic timeline looks like before problems become serious.
Key Takeaway
The Four Clearest Signs It Is Time to Repipe
Recurring leaks, rusty water, low pressure, and old pipe materials are the four clearest signals that whole house repiping deserves serious consideration — not another round of spot repairs.
Seasonal Considerations for Whole House Repiping in the Pacific Northwest
Timing matters for a repipe — and in King, Pierce, and Snohomish Counties, the seasons create real plumbing pressures that homeowners need to account for.
Why Winter Accelerates Pipe Failure
Washington winters bring freezing temperatures, and freezing temperatures are hard on aging pipes. Galvanized steel and older plastic pipes are far more vulnerable to freeze-related stress than modern copper or PEX. When water inside a corroded pipe freezes and expands, a pipe that was already weakened by corrosion is far more likely to crack or burst.
If your pipes have been showing signs of wear heading into fall, winter is when those vulnerabilities tend to reveal themselves in the worst possible way — often at night, often when you’re least prepared to deal with it.
The Best Time to Schedule a Repipe
Spring and early summer are generally the most practical windows for whole house repiping in the Pacific Northwest. Temperatures are mild, the risk of freeze-related complications during the project is low, and scheduling tends to be more flexible before the peak summer rush.
Fall is also a reasonable window — but waiting until late October or November means you’re rolling the dice on whether aging pipes survive another winter. If your plumbing inspection reveals significant deterioration in late summer, don’t delay the decision until spring.
Crawlspace Conditions and Seasonal Access
Many homes in the greater Seattle area have crawlspace plumbing runs. Crawlspace access and site conditions can affect the project timeline, so Pike assesses access during the initial walkthrough and explains any preparation needed before work begins. Standing water in a crawlspace is not normal; if you see it, tell us, because it can point to a leak or drainage problem that should be fixed.
Customers who’ve worked with Pike Plumbing & Sewer on crawlspace repipe projects have noted the difference a well-prepared crew makes. Sabrina Stengle, who had Maxx and the team handle her repipe, noted: “Maxx and his crew were amazing. They were professional, efficient, and left everything clean. I couldn’t be happier with the work they did.” That kind of attention to the details — including crawlspace access and site cleanup — reflects how we approach every project.
What to Expect During a Whole House Repipe
A repipe is a significant project, but it doesn’t have to be a chaotic one. Understanding the process from start to finish helps homeowners plan ahead and avoid surprises.
The Initial Assessment
Before any pipe is touched, a licensed plumber will assess the existing system. This includes identifying what material the current pipes are made of, mapping the supply line routes, evaluating the condition of fixtures and shutoffs, and noting any areas that will require special access.
This assessment drives the scope of the project. A smaller home with straightforward pipe routes is a different job than a larger home with multiple stories, a finished basement, or a complicated crawlspace layout.
The Repipe Itself
Once the scope is confirmed, the actual work begins. Your water will be shut off during active work periods. Most residential repipes are completed in one to three days for the pipe installation itself, though drywall patching and finishing work adds time on top of that.
A well-coordinated crew minimizes the number of wall openings and plans access points strategically — reducing the amount of repair work needed after the pipes are in place. At Pike Plumbing & Sewer, we take that coordination seriously. The goal is a clean result, not just a functional one.
After the Repipe: Testing and Inspection
Before water is restored to the home, the new system is pressure-tested. This confirms that every connection is secure and that there are no hidden issues before the walls are closed.
Once testing is complete and water is restored, you should notice an immediate difference in pressure and water clarity — especially if the old pipes had significant corrosion buildup.
Key Takeaway
What a Complete Repipe Includes
A professional repipe includes an upfront assessment, coordinated installation, and a pressure test before the project is considered complete.

Frequently Asked Questions About Whole House Repiping
How long does a whole house repipe take?
Most residential repipes take one to three days for the pipe installation. Drywall patching and finishing work add additional time. The exact timeline depends on the size of the home, pipe routing complexity, and how many fixtures are being served. Your plumber should give you a realistic project timeline before work begins.
Will I need to leave my home during the repipe?
Not necessarily. Water will be shut off during active work periods, but most homeowners remain in the home throughout the project. Your plumber will communicate daily schedules so you can plan around water shutoff windows.
What type of pipe is best for a whole house repipe?
Whole-house repipes commonly use both copper and PEX. Pike typically uses PEX for most supply runs and copper for stub-outs and other exposed connections, with the exact mix based on the home’s layout and conditions.
How do I know if my home needs a full repipe or just a repair?
A plumbing inspection is the most reliable way to answer that question. If leaks are recurring in multiple locations, if your water is discolored, or if your pipes are made of galvanized steel or polybutylene and are several decades old, a full repipe is likely the more practical long-term solution. A licensed plumber can assess your system and give you an honest recommendation.
