Old or damaged pipes can turn into a constant headache, and many Seattle homeowners eventually reach a point where repairs just don’t cut it anymore. When the plumbing system starts aging out, a complete repiping or targeted pipe replacement can restore safety, improve water flow, and prevent costly water damage that sneaks up on you when you least expect it.
At Gene Johnson Heating, Cooling, Plumbing & Electrical, we have been serving the Greater Seattle area for decades. We got our start as Gene Johnson Plumbing & Heating, and although our services have expanded, plumbing is still at the heart of what we do. Our repipe specialists help homeowners across Seattle, WA, including West Seattle, with reliable, long-lasting solutions that protect their property and save money in the long run.
Our Repiping Services for Seattle Homeowners
We offer a range of repiping services designed to fix small issues before they become expensive repairs and to keep your piping system working in good condition.
Water and Gas Line Repiping
Our water and gas line repiping services address outdated, damaged, or unsafe piping throughout your home. We carefully remove old materials and install modern, code-compliant pipes that improve water pressure, reliability, and overall system safety. From single-line replacements to full-home upgrades, our work ensures your plumbing and gas systems operate efficiently and safely for years to come.
Sewer Line Repiping
Sewer line problems can quickly lead to unpleasant odors, slow drains, and serious property damage if left unaddressed. Our sewer line repiping services replace deteriorating or collapsed pipes with durable materials designed to handle long-term use. By restoring proper flow and structural integrity, we help protect your home from sewage backups, soil erosion, and costly foundation or landscape damage.
Trenchless Pipe Repair
Trenchless pipe repair offers an efficient solution for underground pipe issues without the mess of traditional excavation. Using advanced techniques like pipe lining and pipe bursting, we repair or replace damaged pipes from within the existing line. This repiping approach preserves your landscaping, driveways, and hardscaping while delivering long-lasting results and minimizing disruption to your daily routine.
Appliance Relocation Repiping
Relocating appliances requires precise plumbing adjustments to maintain safety and performance. Our appliance relocation repiping services ensure water and gas lines are properly rerouted to support new layouts for water heaters, boilers, furnaces, or other appliances. We design efficient piping configurations that meet local codes, reduce strain on your system, and allow your remodeled space to function reliably and efficiently.

What to Expect from Gene Johnson During Your Home Repiping
We want the experience to be smooth and predictable, even when big projects like house repiping feel a little overwhelming.
- Step 1: Initial Inspection. We inspect the system to confirm the source of leaks, corrosion, or pinhole leaks, then determine whether partial or whole home repiping is needed.
- Step 2: Planning and Preparation. We map out the line layout, discuss materials like copper pipes or PEX, prepare the work areas, and explain the plan so you are not left with unanswered questions.
- Step 3: Opening the Access Points. We carefully open walls, floors, or the crawl space as needed, taking steps to limit disruption while accessing the old pipes safely.
- Step 4: Installing the New Piping. Our plumbers remove the failing pipes and install new lines that improve flow and reliability, making sure everything is connected properly to faucets, sinks, appliances, and fixtures.
- Step 5: Testing and Clean Up. We test the entire plumbing system to confirm performance, then close up the access points and leave the house clean so the job feels complete.
Once your system is upgraded, we walk you through the results and show you what was replaced. You receive honest recommendations to help keep your new pipes in good condition.
Types of Pipes We Use for Seattle Home Repiping
We use only high-quality materials that provide strength, safety, and long service life for Seattle homeowners.
- Copper Pipes: Copper remains a popular choice because it holds up well to freezing temperatures and everyday use. It does not rust easily, lasts for decades, and supports a steady water supply throughout the house.
- Galvanized Steel Pipes: Some older homes still have galvanized pipes. They can be reliable when maintained, but we mainly replace them because they corrode over time. Updated lines provide better water flow and eliminate problems caused by internal rust.
- CPVC Pipes: CPVC piping is lightweight, efficient, and resistant to corrosion. It is a good option for hot and cold water lines in homes where homeowners want durability without the cost of copper.
- PEX Pipes: PEX is flexible, easy to install, and ideal for tight spaces or long runs behind walls. It also performs well in cold climates and can help reduce leaks because it has fewer connection points.
- Polybutylene Pipes: Many homes built in the past decades still contain polybutylene, which has a reputation for failing over time. We replace these older lines with safer and more reliable materials that protect your property for the long haul.
Choosing the Right Material
We help you compare each type of piping so you can select what works best for your home. Some families prefer the reliability of copper, while others want the flexibility and affordability of PEX. We take the time to explain how each material performs in Seattle’s climate, how long it typically lasts, and what kind of maintenance it may need over the years. Our goal is to give you clear, practical information so the choice feels easy rather than overwhelming.
Every recommendation we make is focused on long-term safety and value. We look at the age of the house, the layout of the plumbing system, and any past issues like corrosion or leaks. Once we understand the full picture, we point you toward materials that will keep your home protected and help you save money in the future.
How Do I Know If My Home Needs Repiping?
If the plumbing system keeps causing trouble, your home may be ready for repiping. Older pipes eventually break down, especially in houses exposed to freezing temperatures or long term corrosion. Watch for warning signs that suggest your pipes are wearing out and may need replacement.
Signs your home may need repiping include:
- Frequent leaks that keep returning
- Low water pressure affecting multiple fixtures
- Rust colored water coming from faucets
- Pinhole leaks in copper or older materials
- Water damage appearing behind walls or ceilings
- Plumbing lines that are more than 40 years old
If you notice several of these symptoms, an inspection can confirm whether partial or whole home repiping is needed.
How Invasive Is Home Repiping?
Home repiping can be somewhat invasive because we often need to open walls, ceilings, or floors to remove old pipes. It depends on the age of the house and how accessible the line routing is. Some older homes have pipes tucked behind multiple layers of materials, so we approach each area with care.
Even though the process can be disruptive, we do everything we can to keep your home comfortable and safe during the project. Our Seattle plumbers cover workspaces, protect your belongings, and clean up daily so the disruption stays manageable. We also communicate clearly so you always know what part of the house we will be working in next.
How Long Does a Full Home Repiping Last?
A complete repiping, when done with high quality materials, can last several decades. Copper pipes and PEX systems routinely provide reliable service for 40 to 70 years when installed correctly. Most homes will never need another full repipe once the job is completed.
Regular inspections and basic maintenance help the new piping system stay in good condition and prevent leaks caused by mineral buildup or pressure changes. With proper care, your updated plumbing will give you peace of mind for a very long time.
How Much Can a Home Repiping Cost in the Seattle Area?
Repiping costs depend on the size of the house, the materials chosen, and how accessible the pipes are. Copper pipes usually cost around 1 to 4 dollars per foot. PEX piping is more affordable and runs about 50 cents to 2 dollars per foot. CPVC and other materials fall into similar ranges depending on market availability and labor.
For an average Seattle house with two bathrooms and around 1,800 to 2,200 square feet, total repiping may range anywhere from 8,000 to 20,000 dollars. Homes with complicated layouts, finished basements, or extensive corrosion may cost more because the preparation and repair work takes longer. An on-site inspection gives you the most accurate estimate, and we are always happy to provide a free quote.
Does Repiping Increase Home Value?
Repiping often adds value because buyers appreciate a modern plumbing system and the reassurance that they will not face slab leaks or corrosion issues after they move in. Updated pipes eliminate concerns about rusty water or structural damage caused by old lines.
Home value benefits may include:
- More interest from potential buyers
- Higher selling price in competitive markets
- Less risk of inspection-related repairs
- Stronger long-term confidence in the property
If you plan to sell in the next few years, repiping can be a smart investment that helps the house stand out.
Can I Repipe Only Part of My Home?
Yes, partial repiping is possible and sometimes the most practical choice. Many Seattle homeowners have small areas of older piping near sinks, water heaters, or bathrooms that need replacement, while the rest of the house remains in good condition. Our team inspects the entire system first so we can determine whether a targeted repair is enough or if a complete repiping is the safer option. Partial projects can save money and reduce disruption while still protecting your home from leaks.

Our technician arrived promptly the morning after we called, he figured out our problem in a short amount of time and then arranged to come out the next day and replace our failed pressure relief valve. We messaged our neighborhood WhatsApp group to see if others noticed increased water pressure. Hugo went above and beyond when he went to our neighbors to test their water pressures to see if they had issues. Some did. I’m sure it will lead to follow on work. He was courteous and efficient. We are happy with his work.
Stuart Webber
Great work, clear explanations, pleasant and courteous…very happy

We had Colby from Gene Johnson come out to estimate a gas line move for a kitchen remodel as well as a tankless water heater. He was professional (they wear shoe covers!), friendly and very honest about the requested services pricing and feasibility with a 100+ year old house. We haven’t chosen them for the actual work yet but most likely will given the experience. I will be sure to update my review when that happens!

Mike K was great. We’re in a new house, so Mike gave great advice on what to watch out for in a brand of toilet we’ve never used. Very friendly and walked me through all of our options to arrive at the best possible price.

Just a small bathroom sink job but Mark was fantastic. All is now functioning properly

Steven and Edgar were professional and timely – great communication as well. Would recommend!

Summary: Gene Johnson sent a tech (Matt Hunter) to address our home heating system, which was sending no heat at all to many rooms in the house. Our system is a wonky spaghetti mess of piping, controllers and pumps that theoretically delivers hot water to legacy cast iron radiators, new floorboard radiators, and seven in-floor hydronic loops. It has not worked as intended since we bought the house 15 years ago. It has likely *never worked right since the last house renovation 25 years go (2000), given the horrid “design” that was implemented then. Matt was the first tech ever to figure out how it all works. He repaired every failed component and problem that could be fixed, given our disastrous configuration. We are completely satisfied with Matt’s work and privately are enormously grateful that this money hole has now been tamed.
Our house dates to 1918, so challenges in upgrading the heating plant in 2000 were a certainty. However, the zoo in our HVAC room is nearly indecipherable. I have hired one HVAC company after another over last 15 years to make sense of it, at great expense.
Ninety percent of past techs gave incomplete explanations, proposed the replacement of a pump or controller, or the addition of a valve, and then left. Some were honest enough to simply offer a theory of how it works, while admitting they didn’t know, and then left us with a big bill.
Enter Matt Hunt. Not sure if Matt looks the part of genius plumber, but then I’ve never seen one till now. He’s a little nerdy perhaps (like me) and also a dirt bike racer. Whatever: Matt alone successfully unraveled the mysteries of our home hot-water distribution plant. He confirmed that the entire house is controlled by two thermostats, which are, incredibly, located just 16 feet apart on the first floor. (One controls all hot water distributed on the north side of the house; one controls all hot water sent to the south side. Go figure.) Matt explained why heat often doesn’t reach the upper floors even when the system is “working” (if it’s warm on the first floor, naturally, no heat is available to the second and third floors).
Matt discovered that the pressure in the water distribution lines was only 4PSI (target range: 13-22PSI), determined that the cause was huge amounts of air in the pipes, and the culprit was a broken refill valve. The new valve includes a pressure gauge so we can now see when the pressure in the water lines has fallen so low that the system can’t deliver hot water to the upper stories. He also spotted problems with the air eliminator, i.e. the “burping” component that normally should purge some/most of the air. He has proposed replacing that (agreed).
Matt drained the pipes on all floors; refilled the lines; purged all zones of air; and replaced the (broken) thermal expansion tank. Heat began to flow again to all rooms. He demosnttated that heat only happens on the upper floors provided that the two first-floor thermostats that control distribution to the entire home are below target temps and are calling for heat.
Matt mapped every radiator and hydronic zone to the main thermostat controlling it. He also determined which rooms/areas the hydronic thermostats control. (Of course, the hydronic thermostats, which are sprinkled around the house, are comic: they only perform as intended when the primary thermostats on the first floor are delivering hot water.) Matt gave us a detailed written explanation of what each component does and how it’s controlled.
Matt did all this in less time than some prior techs took to try and ultimately give up.
Our home heating system is a design wreck and will never deliver heat around the house reliably. However, with the fixes (and insights) mATT delivered, we now get heat when we want it with some work-arounds (like cooling down the first floor therostats). Further, we understand how to spot problems and fix the system going forward.
Thank you, Matt!

Steven came out to troubleshoot our tankless water heater and quickly identified the issue as a clogged condensate pump. What really stood out was the time he took to explain everything in detail. He walked me through the condition of the unit, the manufacturer’s recommended lifespan, and the condensation damage and rust that had already occurred due to the blockage.
Steven gave me honest, thoughtful guidance and helped me make an informed decision about replacing the unit, without any pressure whatsoever. He clearly explained that we could have gotten by with a descaling for now, but also helped me understand why replacing it would likely save money and headaches over the long run.
He was patient, knowledgeable, and answered all of my questions thoroughly. I really appreciated his transparency and professionalism, and I would absolutely recommend Steven and Gene Johnson to anyone needing plumbing or tankless water heater service. Thanks!
Casey Feaster
Very knowledgeable. Mike Keane really did an awesome job. Highly recommend these guys for all your plumbing needs. Definitely going to be a life long customer.
Dana McKenzie
Joseph F came for a leak we were experiencing along with his partner and was beyond helpful. We have a 4 month old and also had a contractor there at the same time. He was kind enough to entertain our little one in his swing while my husband was moving some things in the bathroom and I was talking to the contractor. So unexpected and beyond the call they came out for. Thank you!
