Whole-Home Repipe Cost in Vancouver: PEX vs Copper, Room by Room

The Honest Answer Up Front

A whole-home PEX-A repipe in Vancouver costs $4,800 to $12,000, quoted per home after a walkthrough. The low end of that range is a one-bathroom bungalow with good access — think a 1940s Kerrisdale house on an open crawlspace. The high end is a three-bathroom, two-storey with a finished basement, vaulted ceilings and tile everywhere the pipe needs to hide behind. Copper costs more in material and labour, and it is the right call in some homes; Chapter 3 compares the two honestly instead of selling one.

What the number includes in every quote we write: all supply lines replaced from the main through every fixture, new shutoffs at each fixture, the water heater tie-in, a plumbing permit and the inspections, drywall access openings patched paint-ready, pressure testing, and a 2-year workmanship warranty on the whole system. Nothing in that list is an add-on discovered later, because a repipe discovered-after is the worst version of this project.

Who this guide is for: homeowners of the poly-B era (roughly 1978 to 1995) watching fittings embrittle, owners of pre-1960s galvanized systems watching pressure drop and water discolour, and buyers whose inspection turned up the word polybutylene and an insurance question in the same week. Start with the plumbing services hub, the PEX repipe guide for Vancouver homes, or the plumber page for Vancouver for booking standards.

Why Vancouver Homes Repipe: Poly-B and Galvanized

Vancouver's repipe demand comes from two generations of pipe. Polybutylene — poly-B — was installed across the region roughly between 1978 and 1995, and it ages badly at exactly the points you cannot see: the fittings embrittle, the plastic loses flexibility, and the first failure tends to arrive without warning, usually inside a wall or above a ceiling. It does not need replacing today because a calendar says so; it becomes a repipe when the leak pattern says so, and by then the conversation is usually already late.

The other generation is galvanized steel, standard before the 1960s. It corrodes from the inside out, so the symptoms build for decades: pressure that drops when two fixtures run at once, water with a rusty tinge after a vacation, aerators that clog with debris. Galvanized that is still dry and functional can be lived with, but every year narrows its interior, and the day it starts leaking it tends to keep going.

Copper homes are not exempt — pinhole leaks can appear in copper that is decades old, driven by water chemistry — and some homeowners repipe simply because they are opening every wall for a renovation anyway and this is the cheapest moment in the home's life to do it. If you are unsure which era your home belongs to, the hidden leak detection guide lists the signs worth checking, and a 30-minute walkthrough with one of our technicians answers it definitively.

PEX-A vs Copper: The Real Trade-Offs

This is the decision every repipe quote forces, and the honest version has no villain. PEX-A costs less in material and dramatically less in labour, because flexible pipe fishes through walls and floor assemblies the way rigid copper never will; it carries water with fewer joints, and it expands rather than splits if water freezes inside it. Copper costs more, takes longer, and buys the traditional material: rigid, impermeable, immune to UV in exposed runs, and familiar to every plumber who will touch the house for the next fifty years.

Our default recommendation for Vancouver homes is PEX-A, with copper reserved for exposed runs, mechanical rooms and owners who want the traditional material at its price. Neither is wrong; they are trade-offs, and a quote that shows the line-item difference for your home is doing its job. For the deeper version of this comparison, the PEX repipe guide walks fittings, manifolds and routing in detail.

What Moves a Repipe Quote

The $4,800-to-$12,000 spread is not negotiation room; it is scope. These are the factors that decide where your home lands, in rough order of weight.

A note on material prices: copper tracks metal markets, and the spread between quotes two months apart can reflect the commodity, not the contractor. PEX pricing is steadier. When you compare repipe quotes, ask each company what material and what generation of fittings the price assumes, because PEX-A at expansion-fitting quality and PEX-B at crimp-ring quality are different products with different long-term behaviours.

Room by Room: What Each Scope Adds

A repipe is priced by fixture count and routing difficulty, which means the room list below is really the quote's table of contents. This is the scope we measure on the walkthrough, and it is why two houses on the same street can land $4,000 apart honestly.

The one scope decision worth making deliberately: valve quality at the fixture. A repipe is the moment to install proper quarter-turn shutoffs everywhere, because ten years from now the person fixing a faucet will either thank you or curse the multi-turn stops that were cheaper on the day.

The Job Itself: 3-5 Days, Permitted and Tested

Here is what the week actually looks like, because homeowners picture this project worse than it is. Day one: floor protection out, the plumbing permit posted, access openings cut where routing demands them, and the new main, manifold and trunk lines started. Middle days: home-run lines fished to each fixture, new shutoffs set, fixtures reconnected. Final day: pressure test on the whole system, the plumbing inspection, drywall patches finished paint-ready, and the old pipe hauled out.

Water is off during working hours — typically 8 to 4 — and back on every evening, with the kitchen and one bathroom hooked up first so the house stays liveable. Most families stay home for the whole project; the house is dustier than usual and there are a few holes in the wall on Wednesday that are patched by Friday, which is the honest description of a repipe week, not the brochure version and not the horror version.

The inspection is worth a paragraph of respect. A permitted repipe in any Metro Vancouver municipality is inspected, and the record of that permit is the single document that settles insurance questions, buyer questions and resale-value questions years later. Skipping the permit to save a small fee is the most expensive economy available in this trade; we include it in every quote without being asked.

Poly-B, Insurance and the Paper Trail

The insurance angle is now the quiet driver of most repipe decisions in Vancouver. Several insurers ask about polybutylene on new applications; some load the premium, some exclude water damage from poly-B failures, and some require replacement before binding. If you own a poly-B home, the practical sequence is: read your policy language, ask your broker directly, and get the answer in writing, because this is a market that shifts year to year and the answer belongs on file, not in a phone call.

What a completed, permitted repipe does is remove the question. The documentation our jobs close with — permit record, inspection sign-off, materials list, flat-rate invoice, photos, and the 2-year workmanship warranty — is exactly the package an underwriter wants, and exactly the package a buyer's inspector will hand to their client as a resolved item rather than a flagged one. In transactions we see, that paper routinely pays for itself in negotiation, and always pays for itself in certainty.

Partial Repipe vs Whole Home: The Honest Test

We do spot repairs every week, at $180 to $420, and they are the right call constantly: an isolated failure on an otherwise sound system deserves exactly that, and nothing more. The honest test is pattern. One leak in fifteen years is a repair. Three leaks in three years is the material telling you its plans, and on poly-B or galvanized, the material's plans are always the same — the failures continue, in places you cannot see, until the system is replaced or the house is opened for something else.

The economics compound quietly. A partial repipe moves the failure down the line, because the pipe you did not replace is the same age as the pipe that just leaked; two or three $400 repairs plus one $850 burst inside a finished ceiling, inside a few years, is repipe money spent without a repipe. And each emergency visit carries the possibility of the 2 AM premium, which Chapter 9 of the emergency plumbing guide explains, because after-hours failures on aging pipe are where the real cost of deferring a repipe shows up.

There is also a legitimate middle path we quote regularly: whole-home repipe with a phased schedule — wet walls this year, remaining runs at the next renovation — priced so the phasing is deliberate rather than accidental. The honest framing is that deferring is a decision; make it on purpose, with numbers, not by hoping.

Why PEX-A Is Our Default

PEX-A is the expansion-fitting generation of PEX, and the difference is in the joint. The fitting is inserted with an expansion tool, and the pipe shrinks back around it, forming a seal with no crimp ring biting the pipe — which means the failure points that age in a crimped system simply do not exist here. In a wet, mild climate with occasional hard freezes in exterior walls, the other property matters too: PEX expands with frozen water and usually survives it, where copper and older plastics split.

The manifold-and-home-run architecture we install with it is a quiet upgrade to daily life: each fixture gets its own dedicated line from a central manifold, so a shower stays steady when a toilet flushes, a fixture can be shut off alone at the manifold, and pressure balances across the house the way trunk-and-branch systems never quite managed. It costs a modest premium over PEX-B per foot — small against the total of a whole-home job — and it is the standard we install, backed by the 2-year workmanship warranty on the system.

What PEX is not: a material for long UV exposure or unprotected mechanical damage, which is why exterior and exposed runs get copper or protection. Every material has a lane; the honest design uses each one where it belongs, and the plumbing services hub covers the rest of the list.

How to Compare Repipe Quotes

Repipe quotes are the easiest in the trade to compare dishonestly, because the bottom numbers look similar while the scopes hide the difference. Five lines decide it: the material by type and generation (PEX-A at expansion fittings is a different product from PEX-B at crimp rings), the drywall scope (who patches, to what finish), the permit line (included or not, and it should be), the fixture valves (proper quarter-turns or the cheapest stops), and the warranty in writing.

Our answers to the five, so you have a baseline: PEX-A with expansion fittings by default; patching included and left paint-ready; permit and inspection included; quarter-turn shutoffs at every fixture; 2-year workmanship warranty, licence BC-PL-2019-4421, $2M insured. For standard repair rates to compare against, the plumber cost guide for 2026 has them, and the city pages — like plumber Burnaby — carry the same model region-wide.
