When Patching Stops Making Sense

Every plumber reaches a point with a client where another patch repair is no longer the right call. When pinhole leaks appear in the copper every few months, when galvanised pipe pressure has dropped to a trickle, when polybutylene fittings have failed twice in a year — the conversation shifts from repair to replacement. A whole-home repipe is a significant investment, but it is also the definitive solution to a systemic plumbing problem. This guide tells you exactly when to make that call, what materials to use, what it costs in Vancouver, and what to expect during the process.

Signs Your Vancouver Home Needs a Full Repipe

Not every plumbing problem calls for a full repipe. But these specific patterns indicate that the supply system as a whole has reached the end of its reliable service life:

  • Repeated pinhole leaks in copper: Copper is excellent pipe — under normal conditions. But in some Vancouver homes, particularly where water pH or chloramine levels have interacted with Type M copper (thinner-walled), pinhole corrosion develops throughout the system. If you have had more than two pinhole leaks in different locations within a few years, the entire copper supply is suspect
  • Polybutylene (PB) pipe: Grey or blue flexible plastic pipe installed in homes from approximately 1978 to 1995. PB reacts poorly to chlorine in municipal water over time, becoming brittle and prone to sudden catastrophic failure at fittings. Most BC insurers no longer cover homes with original PB pipe. See our dedicated guide on polybutylene pipe replacement for full detail
  • Galvanised supply throughout the house: Low pressure, rust-coloured water, and chronic leaks at joints. Once galvanised pipe internal corrosion reaches this stage throughout the interior, targeted repairs are not cost-effective
  • Discoloured water from all hot and cold taps: Indicates supply pipe corrosion rather than a water heater or drain issue
  • Low pressure across every fixture simultaneously: When pressure is weak everywhere at the same time, the problem is systemic rather than localised
  • Insurance ultimatum: Insurer has flagged the pipe material and given a replacement deadline

Material Options: PEX A/B vs Type L Copper

Two materials dominate whole-home repipes in Vancouver: PEX tubing and Type L copper. Both are BC Plumbing Code-approved. Here is a straightforward comparison:

  • PEX A: The most flexible PEX variant. Can be expanded at fittings for exceptionally secure connections with no crimps. Excellent freeze resistance — it can expand rather than burst. Easier to route through wall cavities than copper, reducing drywall cutting. Cost-effective. Our most common repipe material
  • PEX B: Slightly stiffer than PEX A, uses crimp or clamp fittings. Also excellent performance. Lower material cost than PEX A. Both PEX A and PEX B have a long track record and are the go-to for most professional repipers in British Columbia
  • Type L copper: Heavier-wall copper with a proven 50+ year track record. Preferred by some insurers, lenders on high-value homes, and clients who want a fully traditional material. Higher material cost and more labour-intensive to install (requires soldering or press-fit connections). Better suited to locations with UV exposure or where pipe may be visible and aesthetics matter

We discuss both options with every repipe client. In most Vancouver homes, PEX A is the practical choice for its combination of performance, ease of installation, freeze resistance, and cost. On heritage or high-end homes where pipe may be partially visible, Type L copper is often the better fit.

Typical Whole-Home Repipe Costs in Vancouver

Repipe costs in Vancouver vary significantly based on home size, number of bathrooms, number of storeys, wall construction type, and how much finish-out (drywall repair, painting) is included. Typical ranges:

  • 2-bedroom condo or townhouse: $8,000–$12,000 (PEX, 1–2 bathrooms, includes permit)
  • 3-bedroom detached house, single storey: $10,000–$16,000
  • 3–4 bedroom, two storey: $14,000–$22,000
  • Larger homes (5+ bedrooms, multiple bathrooms): $20,000–$25,000+
  • Type L copper vs PEX: Copper adds approximately 20–35% to the material cost
  • Drywall and plaster repair: Typically quoted separately or as a line item; budget $1,500–$5,000 for a typical house depending on the extent of wall access required

These are ranges, not fixed quotes. The only way to get an accurate number for your specific home is an on-site assessment. We provide written, itemised quotes — no vague estimates.

How Long Does a Repipe Take and What Is the Disruption?

A typical Vancouver whole-home repipe takes 2 to 5 working days of plumbing work. Water is generally shut off during working hours but restored each evening. Here is what to expect:

  • Day 1: Main shut-off confirmed, routing planned, and old pipe removal starts. New pipe rough-in begins
  • Days 2–3: New supply piping completed throughout the house; connections made to all fixtures
  • Day 4: System pressure-tested. Plumbing rough-in inspection booked with the city
  • After inspection passes: Walls are patched and finished. Final fixture connections made

We minimise wall openings by planning pipe routes to use existing floor, wall, and ceiling cavities wherever possible. In a PEX repipe, flexible tubing can often be snaked between storeys without opening every wall — this is one of PEX's key advantages over copper in a retrofit repipe.

Permits and What Happens Without One

A whole-home repipe requires a plumbing permit in every municipality in Greater Vancouver. The permit requires a rough-in inspection before walls are closed and a final inspection. A repipe done without a permit will surface as a serious problem during a future home sale, insurance claim, or renovation permit application. We handle all permit coordination as part of our standard project scope.

If you are also replacing the water main from the street as part of the project, that requires a separate permit — see our water main repair page for that scope of work. For more on polybutylene-specific replacement, see our post on PB pipe replacement in Vancouver.
