How to Choose a Repiping Company
By Ramin Shahbaziasl, Owner, Eastside Repipe and Plumbing · Last updated October 28, 2025
Finding a repiping company you can actually count on isn't easy. Everyone claims to be the best, but when the leaks come back, or the bill suddenly doubles, that claim doesn't hold up. You don't need flashy promises. You need someone who shows up, does the work properly, and stands behind it.
That's what we aim to be. Repiping is what we specialize in, not one service among many, which means we've seen what old pipes hide, where leaks tend to start, and how to fix it properly the first time.
When You Actually Need a Repipe
Sometimes a small leak isn't a small problem. It's a symptom.
Maybe a wall has started staining, or pressure is dropping in different parts of the house at different times. A plumber fixes one section. Two months later, another leak appears somewhere else. Same underlying issue, different spot.
That pattern is the signal to stop patching and start thinking about the whole system.
Signs it's time: a home over 30 years old, original galvanized or polybutylene pipe, brownish water, rattling in the walls, or leaks that keep recurring in different places. At that point it's not just a plumbing decision. It's about the house itself.
Why Specialization Matters
A general plumber fixes leaks. A repiping specialist rebuilds the entire supply system properly, and the difference shows up in the details: teams trained specifically for this kind of work, real experience with walls, permits, and inspections, and a process that doesn't leave your home looking like a construction site for a week.
You don't want someone learning the process on your house. You want a crew that's done it hundreds of times.

What a Good Repiping Company Actually Brings
Licensing, Insurance, and the Details That Matter
Start with the basics: licensed, insured, and bonded. You can verify any Washington contractor's license, bond, and insurance for free through the state Department of Labor and Industries rather than taking their word for it.
Then go further. Ask what material they're recommending and why, what their process looks like, and how long they've specifically been doing repipes rather than general plumbing. A company worth hiring explains the reasoning behind a quote rather than just handing you a number, including why they'd choose PEX-A over copper for your specific situation and what your home's water chemistry has to do with it.
How They Treat Your Home
This is where the difference is easiest to see. A good crew covers floors, counters, and furniture, cuts clean and controlled openings, and patches everything afterward, sometimes including the paint. A rushed crew leaves dust everywhere and messy cuts with no real cleanup. Watching how a company treats the house tells you a lot before the quote does.
Copper vs PEX
Copper. Durable, fire-resistant, and it's been the standard for decades. It costs more, and in some water conditions it can corrode gradually over time. If you're planning to stay in the home for decades and want a material with the longest track record, it's worth the extra cost.
PEX. Flexible, affordable, and it needs fewer joints than copper, which means fewer potential weak spots. Fast to install and considerably easier on the budget.
One detail worth knowing: not all PEX is the same. PEX-A is the standard worth asking for specifically. PEX-B and PEX-C are lower grades used by some installers to cut cost, and the difference shows up in flexibility and long-term reliability. Always ask which grade is being used before you sign anything.

What Drives the Cost
A full repipe typically runs from several thousand dollars into the tens of thousands, depending on complexity. What actually moves that number:
Access. Slab homes require more labour than a house with a crawlspace or basement
Material. Copper costs more than PEX
Finish work. Drywall repair, paint, and cleanup all add up
Permits and inspections. Necessary, and they take both time and money
A properly run repiping company explains every line of the quote rather than handing you a single number with no breakdown. Our plumber cost guide covers typical local pricing.
How Long It Actually Takes
A skilled crew repipes most homes in one to two days, with an additional day or two for patching and painting. That's the realistic timeline for a well-run job.
An inexperienced or disorganised crew can stretch the same job out to a week or more, and going without water for that long gets old fast. When comparing quotes, ask about the schedule directly: when work starts, when water comes back, and what happens after inspection.
How to Vet and Compare Contractors
Build a shortlist. Don't hire the first name on Google. Get three to five options, looking for companies that specialize in repiping rather than general plumbing, verified reviews, and before-and-after photos.
Ask direct questions: Do you handle permits and inspections? Will your crew patch and repair walls afterward? How long will the whole job take? What warranty comes with the work? Vague answers are the clearest red flag available.
Compare scope, not just price. Some bids skip drywall repair. Others exclude inspection costs or quote a lower material grade. Make sure you're comparing the same scope of work before comparing numbers.

After the Job
New pipes are in. A few things still matter.
Get your documentation. Permits, inspection sign-offs, and warranties in writing.
Ask for as-built notes showing where the new lines actually run.
Confirm your shutoff valve locations before the crew leaves.
Keep their contact details for future maintenance.
Ongoing maintenance that protects the investment:
Keep water pressure reasonable. High pressure shortens pipe life regardless of material
Watch for discoloration or unusual smells early
Insulate any exposed pipe in cold spots
Consider a filter or softener if your water is hard or corrosive
Which Material Adds More Resale Value
Updated plumbing generally supports resale value, since it removes a known deduction from a home inspection. If you're planning to sell soon, copper is sometimes viewed as the more premium choice by inspectors and buyers. If you're staying long term, PEX-A performs just as well at a lower cost, which matters more if resale isn't the immediate priority.
Either way, a full repipe done properly outperforms ongoing patchwork repairs on cost over time.
Frequently Asked Questions
What's the difference between a plumber and a repiping company?
A plumber fixes individual leaks. A repiping company replaces the system as a whole. If you're dealing with recurring leaks in different spots, that's the signal to move beyond repairs.
How long does repiping take?
Most homes are fully repiped in one to two days, with patching following soon after. Larger or older homes can take longer.
Will repiping damage my walls?
There will be small, controlled openings for access, which a professional crew patches and finishes afterward. Some disruption is unavoidable but should be minimal and short-lived.
What's better, copper or PEX?
Copper is durable and long proven. PEX is flexible and more affordable, with PEX-A being the grade worth asking for specifically. The right choice depends on your water chemistry, home layout, and budget.
Does repiping increase home value?
Generally, yes. It reduces the risk of future leaks and removes a known deduction during a home inspection, particularly when the work is done by a licensed, verifiable contractor.
