If your North Vancouver home was built between 1978 and 1995, the grey pipe behind the drywall is very likely Poly B. We replace it in PEX-A and hand you the paperwork your insurer asks for.
Poly B is the grey plastic supply pipe stamped PB2110 that went into Canadian homes from 1978 until roughly 1995. It was designed for about 25 years of service, which means every system still in the ground in North Vancouver is past it.
Lynn Valley and the upper slopes filled in through the Poly B years, so those are the North Van addresses most likely to have it.
It fails from the inside out — chlorine in the municipal supply makes the pipe wall brittle, and the original grey acetal fittings are the weakest point in the whole system. Nothing about that is visible until water appears somewhere it should not.
We replace the lot in PEX-A, plan the routes first so we open as few walls as possible, and finish with the permit, the inspection record and photographs.

Permitted work in North Vancouver goes through the City or District of North Vancouver, depending on your address. We pull it and book the inspection as part of the job — you do not deal with the city.
The full rundown: why Poly B fails, what replacement involves, how long it takes and what it costs.
How Poly B replacement works →The North Shore is mixed. Lower Lonsdale and parts of Capilano are older, while a great deal of Lynn Valley and the upper slopes filled in through the Poly B years.
North Vancouver takes more rain than anywhere else in Metro Vancouver, and the steep lots mean perimeter drainage and sump pumps work hard every winter.
We will confirm whether it is Poly B, what condition it is in, and what replacement would cost in North Vancouver. No charge.
