What Does Poly B Replacement Cost?
Whole-home Poly B replacement typically runs $8,000 to $18,000 in total, with most single-family homes landing between $10,000 and $13,000. Where your home falls in that range comes down to real, specific factors — not a flat per-square-foot rate — which is why we never quote a fixed number without seeing the job.
Expect roughly $800 to $1,500 added per bathroom beyond the base scope, since every additional fixture group means more pipe runs and more access points to open and close. Want a personalized planning range before you book? Try our free Poly B replacement cost calculator.
What Drives the Price
The Real Cost Drivers
Home size and the number of fixtures and bathrooms are the biggest factors — more plumbing runs mean more pipe, more time, and more wall or ceiling access. The number of storeys matters too, since multi-level homes need vertical runs that single-storey homes don't.
How your home is built changes the job as well: a slab-on-grade home is a different repipe than one with a full basement or crawlspace, and finished walls that need to be opened and closed add a drywall-restoration step that unfinished basements skip. Fixture relocations — moving a sink or shower rather than repiping it in place — also add cost.
Access is the factor homeowners underestimate most. A home with an open, unfinished basement is generally faster and less costly to repipe than one where every run is buried behind finished walls and ceilings, simply because there's less cutting and less drywall to restore afterward.
One Price, Not Two Bills
Why We Quote the Pipe and the Drywall Together
A whole-home repipe means cutting into walls and ceilings, and most plumbers leave you to find and pay a separate drywaller to close everything back up. We don't — our in-house drywall team is part of the same quote, so the number you get covers the pipe and the walls in one price, not a plumbing bill stacked on top of a drywall bill you have to chase down yourself.
That also means one schedule instead of two, and no gap where your home sits torn open waiting for a second contractor to show up.
It also removes a common source of scope disputes — when the plumber and the drywaller are two different companies, disagreements about who's responsible for what can leave homeowners stuck in the middle. With one crew and one quote, that problem doesn't come up.

Common Questions
Frequently Asked Questions
How much does Poly B replacement typically cost?

Does the price include fixing the walls afterward?
Yes — our in-house drywall team is part of the same quote, so you get one price for the pipe and the drywall restoration together, not a separate bill later.
Why does the cost vary so much between homes?
Home size, number of bathrooms and storeys, whether you have a basement or slab foundation, and how much finished wall needs to be opened and closed all change the scope of the job.
Do you offer financing?
Not yet on a confirmed program we can advertise. Every quote is fixed and written up front regardless, so there are no surprise costs either way.
How do I get a firm price?
Request a referral — a licensed plumbing contractor inspects your home and gives you a firm, written quote with no obligation.
How much does it cost to replace Poly B in a 1500 sq ft house?
Poly B repipe cost tracks fixture count and how reachable the runs are far more than floor area alone, so a 1500 sq ft bungalow with one bathroom and a 1500 sq ft two-storey with three can land a long way apart. The calculator builds a range from your own home's details rather than a square-foot rule of thumb.
Why are repipe quotes so different, and how do I compare them?
Two quotes for the same house diverge most often because one includes restoring the walls and the other stops at the pipe. When you compare repipe quotes, line them up on four things: what is being replaced, whether every opening is patched and finished, whether permit and inspection are included, and what happens if something unexpected turns up once walls are open. A Poly B replacement quote comparison is only fair when all four match.
What affects repipe cost, and what are the hidden costs of repiping?
What affects repipe cost most is fixture count, number of storeys, and how much of the run can be reached without opening finished ceilings. The hidden costs of repiping usually sit after the plumbing rather than in it - patching, texture matching and paint. A number that looks like affordable repiping can finish higher than a complete quote once that work is added back.
Does a repipe include drywall repair?
Ask explicitly, because it is the single biggest reason quotes differ. A Poly B replacement cost with drywall repair should cover every opening made during the work, patched, finished and left paint-ready. Where a cheap Poly B replacement excludes it, the wall work returns later as a second trade and a second bill.
What is the Poly B replacement price in 2026?
Poly B replacement cost 2026 still has no single national number - it comes down to fixture count, access, and whether restoration is included. The calculator gives a range from your own inputs, and a firm Poly B replacement price only comes from a licensed contractor who has seen the home.
How to compare repipe quotes when one includes the drywall?
Start with one question - does repipe include drywall repair - and put it to every bidder in the same words. That single line explains most of the spread between quotes, because a plumbing-only price and a plumbing-plus-restoration price are not the same product being sold.
