Dana Sirois from Maple Leaf Radon Defence

Dana Sirois is a Master mason by trade. With an incredible 45 years of foundation and Masonry experience. He started in the industry in the early 1970s and has worked many Heritage, commercial and residential buildings in Canada during his years. Dana has always been ahead of his time when it comes to customer care making sure the job is done well even going as far as doing extra work and not charging the homeowner or simply leaving the job better than when he got there. Dana makes sure everyone at Maple Leaf Radon Defence continues that effort in "WOOWING" the homeowner. That is one of the many reasons why he is well-known in Ontario.
