Poly-B Replacement in North Vancouver
If your home was built between 1985 and 1997, the grey plastic water pipe in the basement or behind the walls may be Poly-B. The plastic fittings get brittle and split at a joint, and the first sign is usually a stain on the ceiling or a drip under the floor. We swap it for PEX or copper and walk you through the work first.

Signs Your Home Has Poly-B
A few minutes in the basement usually tells you whether this is the pipe you have.
Dull grey pipe
Flexible grey pipe about the width of your thumb, often stamped "PB2110" along the side.
Crimped joints
Metal or plastic rings clamped at each fitting, with no threads. The joints are where leaks usually start.
Built 1985 to 1997
Poly-B was common through the late 80s and 90s. If that is your build year, it is worth a look.
A note from your insurer
Some insurers now ask about Poly-B or hold off on renewing until it is replaced.
Replacing the Pipe, Room by Room
We replace the Poly-B running through your home with PEX or copper, starting at the main shutoff and working out to each fixture. Where we can, we run the new lines through the basement, crawlspace, and open walls so we cut as little drywall as possible.
Before we start, we walk the house with you and mark where the pipe runs, where we need access, and which walls or ceilings may need a small patch after. You get the price in writing before any cutting begins.
