Poly B Replacement in Oak Bay, BC
Oak Bay's character homes are mostly older than the Poly B era — but a generation of bathroom and kitchen renovations between 1978 and 1995 introduced Poly B selectively into many properties. We find it, replace it with PEX-A, and document the work for your insurer.
What Oak Bay Homeowners Say About Our Poly B Work
Real Victoria homeowners. Real jobs. Real results.
"I am a loyal customer with Clear Choice plumbing. I have PolyB (a real nightmare) plumbing. My first leak was above the kitchen fixture. Tyler fixed it and recommended that I have all PolyB removed and replaced with PEX. His quick estimate was accurate and the work was done on time. My home insurance company was ok with the results. Highly recommend."
"The Clear Choice team did an excellent job replacing the extensive Poly-B plumbing throughout our house and upgrading several outdated fixtures at the same time. They even repaired a damaged sewer pipe that was discovered while replacing the underground Poly-B connected to the municipal water meter. Professional, thorough, and great value."
"Clear Choice was exactly what their name says. They replaced old poly b pipe with PEX in the time they said for the price they said. Communication and professionalism was clear right from the start. Great team!"

Oak Bay is one of Greater Victoria's oldest and most prestigious municipalities — and that age profile changes the Poly B story. Most of Oak Bay's housing stock predates the 1978-1995 Poly B era entirely, which means the original plumbing in an Uplands estate, an Estevan Village craftsman bungalow, or a Henderson-area home is more likely to be galvanized steel or cast iron than polybutylene. But that's only the original plumbing. Decades of bathroom and kitchen renovations between 1978 and 1995 introduced Poly B selectively into many Oak Bay homes, hiding alongside the original galvanized everywhere else. We find it, replace it, and document the work.
Why Oak Bay Has Less Poly B (But Why It's Still a Real Issue)
Oak Bay's housing stock is dominated by pre-1970 construction. The municipality has one of the highest concentrations of pre-1970 homes in Greater Victoria — character bungalows in Estevan Village, stately estates in Uplands, mid-century homes along Cadboro Bay Road, and the older blocks of Henderson. The original plumbing in those homes was installed decades before polybutylene became the BC residential standard. So if Oak Bay homeowners ask us "should I worry about Poly B?", the honest first answer is: probably less than your friends in Saanich or Langford.
But that's only the original plumbing. The complicating factor is renovations. Most Oak Bay homes have been updated multiple times over the past 50 years — kitchens redone in the 1970s, bathrooms in the 1980s, additions in the 1990s. Many of those renovation projects, particularly the bathroom and kitchen work done between 1978 and 1995, used Poly B for the new branches. The result is that an Oak Bay home built in 1932 might have original galvanized supply lines feeding most of the house, copper running to a 1965 bathroom upgrade, and Poly B feeding the master ensuite added in 1987. All in the same house.
So when we assess an Oak Bay home for Poly B, we're not asking "is the house plumbed in Poly B?" We're asking "where did renovation work introduce Poly B branches?" That's a different diagnostic — and it's why a casual visual check often misses it.
Finding Poly B Among Oak Bay's Multi-Era Plumbing
Identifying Poly B in an Oak Bay home is a more careful diagnostic than the same job in a younger neighbourhood. The visual signature is consistent — grey (sometimes black) plastic pipe, typically stamped with "PB" — but in Oak Bay it's usually surrounded by other materials. We check every accessible point: under all sinks, at the water heater, in basement and crawlspace ceiling runs, at every fixture connection, and wherever an addition or renovation joins original construction. Where there's a finished basement or sealed wall section, we work from the visible portions of the system to map what's likely behind the walls.
Some Oak Bay homes have very little Poly B — a single bathroom branch that we can replace in half a day. Others have substantially more — an entire wing of additions and updates done during the Poly B era — which means a longer project. We tell you which one your home is before quoting, and we don't oversell scope. If a single branch is all that needs replacement, that's what we quote. If insurance is requiring full removal of any Poly B regardless of how isolated, we'll discuss what the policy actually requires before deciding scope.
Replacing Poly B in a Heritage Oak Bay Home
The other thing that makes Oak Bay Poly B work different is the construction itself. Most Oak Bay heritage homes have lathe-and-plaster walls instead of modern drywall, original hardwood floors, period mouldings, leaded glass, and finishes that are either irreplaceable or expensive to restore. A repipe job here is fundamentally a careful-access exercise. We plan every wall opening in advance, we route PEX-A through original chases and ceiling pathways wherever possible, and we cut plaster only where unavoidable — and when we do, we cut clean and small.
We pull the District of Oak Bay plumbing permit, schedule the inspection, and hand you the signed-off inspection certificate when we finish. That certificate is exactly what your BC insurer needs as documentation. For larger plaster restoration work after the project, we can refer you to a trusted heritage plaster restoration specialist who understands what 1920s lathe-and-plaster actually requires (it's not the same as patching drywall). Most Oak Bay Poly B projects take 2-4 days depending on scope — longer than a Saanich or Langford repipe of equivalent size, because the work needs more planning and slower execution.

Less common than in Saanich or Langford, but very real. Oak Bay's housing stock is older than the Poly B era — most original construction is pre-1970, before polybutylene was the dominant material. But Oak Bay has had decades of bathroom and kitchen renovations, and many of those were done between 1978 and 1995 when Poly B was the standard pipe for new work. So instead of a whole house plumbed in Poly B, an Oak Bay home is more likely to have Poly B in selected branches — feeding the master ensuite added in 1986, or the basement suite roughed in during a 1991 update — alongside original galvanized everywhere else.
The visual signature is the same as anywhere else: grey (sometimes black) plastic pipe, often with the letters PB stamped on it, found under sinks, at the water heater, or in basement ceiling runs. In Oak Bay specifically, what makes diagnosis harder is that Poly B is usually mixed with two or three other pipe materials in the same house — original galvanized steel, copper from a mid-century renovation, and Poly B from a 1980s update can all coexist. We do a full visual assessment to identify every Poly B run, not just the obvious ones.
Longer than a standard repipe — typically 2-4 days vs 1-2 for a newer home of equivalent size. The reason is the construction. Oak Bay heritage homes have lathe-and-plaster walls instead of modern drywall, tighter clearances, original layouts that don't match modern routing assumptions, and finishes you absolutely don't want to damage (plaster mouldings, hardwood, original built-ins). We work more carefully and route more thoughtfully, which adds time. The trade-off is that the home looks the same when we're done.
We minimize wall opening as much as possible by routing PEX-A through existing pathways — original chases, basement and crawlspace ceilings, attic spaces — and using small targeted access holes only where unavoidable. For a 1920s Estevan Village or Henderson home with intact original plaster, we plan every access point in advance and discuss it with you. Where we do need to cut plaster, we cut clean and small. For larger restoration, we can refer you to a trusted plaster restoration specialist who understands heritage finishes.
Yes. The District of Oak Bay requires a plumbing permit for full or partial repiping work, and the work must be inspected on completion. We pull the permit, schedule the inspection, and provide the signed-off inspection certificate when we finish. This certificate is what your insurer wants as proof that the Poly B has been properly removed and replaced to BC code.
Cost depends on how much Poly B is actually present (often less than expected in Oak Bay because it's mixed with other materials), home size, the condition and accessibility of the existing plumbing, how much plaster needs to be opened, and whether the heritage character of the home requires extra care. We provide a fixed written quote after a thorough on-site assessment. Financing is available through Financeit at 0% interest. Call (778) 265-6446 to book an Oak Bay Poly B inspection.
