Brian Hayes Plumbing was a tremendous help in renovating our ensuite bathroom. Their work in assisting us with design and performing the installation went smoothly and efficiently in a timely manner. The staff were friendly, courteous and eager to help in any way at all times, even resolving last minute extras. Thanks to all!

Darryl and his team have helped us out several times over the years but last week when I called in a panic because I had no water, not only did they fix the problem but Darryl has continued to monitor the issue on a daily basis, as it may take up to a week to be totally resolved. I have always held DSM Plumbing in high regard but this experience has taken great customer service to the next level, I know I can always count on DSM Plumbing to come to the rescue when things go wrong.

I've used Vaillancourt three times now and am VERY satisfied and impressed. Mark was thorough and efficient - he did a wonderful job fixing our problems. And Patsy at the office? She's fantastic and always gives GREAT customer service. USE THEM - you won't be sorry!!
