Poly-B plumbing: what Ottawa homeowners should know

Grey poly-B supply lines in 1985-97 Ottawa homes, why insurers worry about them, and replacing them during a renovation.

Homes built roughly between 1985 and 1997 often have grey poly-B (polybutylene) supply lines. That covers large parts of Kanata, Orléans, Barrhaven and South Keys. Insurers increasingly treat it as a concern.

The concern

Poly-B has a history of failures at fittings and connections. Some insurers now decline coverage or add a surcharge for homes that still have it. A failure can mean significant water damage.

Replace it during your reno

If you are already renovating a bathroom, kitchen or basement, it's the ideal time. That's when to replace poly-B with modern PEX or copper, with no duplicate drywall work later. It gets done once.

How we help

We flag poly-B at quote time and scope the replacement honestly: what actually needs doing, not what would be overkill. We complete it as part of the renovation, so you only pay for finishing once.
