Our history

A family tradition since 1955!

As Durham Region's oldest plumbing and drain company, Vaillancourt Plumbing & Drains has been serving the plumbing needs of residential and business customers since 1955 — a testament to our customer-centric approach to our business. As founder Ed Vaillancourt says "Service is our business!" Although daily operations have passed forward to Ed's son, Brian Vaillancourt, Ed still advises, drawing upon his many years of experience and expertise. We are committed to a high-level of quality workmanship and customer care when it comes to your plumbing needs. Our expertise, friendly service and competitive rates will ensure you receive the exact repairs you need.

Had an estimate done for a fairly significant job - relocation of a laundry room. Very detailed, professional, and provided options that others hadn't, also appreciated explanation of building code policies. Impressed by the time spent and obvious expertise.
