Replace Poly-B Without the Chaos.
Calgary’s turn-key solution for aging water lines. Permits, plumbing, patching, and paint handled start to finish so your home’s back together faster and your insurer’s satisfied.
What is Poly-B
Polybutylene (Poly-B) is grey plastic water line used in many Calgary homes built from the 1980s to late 1990s. It was later removed from the Canadian plumbing code due to higher leak risk as it ages. Westland Insurance
Why people replace it?
• Insurance: some insurers surcharge, exclude water-damage claims tied to Poly-B, or refuse coverage until it’s replaced.
• Risk profile: Poly-B can embrittle over time, especially with hot, chlorinated municipal water.
Permits and compliance
In Calgary, altering a domestic water system requires a plumbing permit. We handle permits and inspections. https://www.calgary.ca

What it can cost
Public, Calgary-area reports show whole-home projects commonly landing in the mid-thousands to low-teens depending on size, finish level, and whether drywall/paint is included. Examples shared: ~$6k plumbing only with DIY patches; ~$10–11k including drywall/paint for bungalow/2-storey; similar totals when trades split plumbing and finishing. Your home’s size, ceiling type (textured vs flat), and finished basement access drive variance. Reddit

FAQs
Do I need to replace every inch?
Best practice is full replacement. If a small, inaccessible fraction remains, we disclose it and discuss risk. Some homeowners phase work during other renos to reduce disruption. Reddit
Will my insurance get better?
Insurers differ. Many improve terms or remove exclusions once Poly-B is replaced and documented. We provide proof of work and permits to support your file. MyChoice
Is Poly-B safe if it hasn’t leaked yet?
Absence of leaks isn’t a guarantee. Degradation is chemistry- and time-driven and accelerates with hot, chlorinated water. Replacement removes that category of risk.
What about permits?
We pull the plumbing permit, book inspections, and share the approval record for your files. https://www.calgary.ca
