About Us

History of the Marleau Family/Group Making the Cornwall Landscape for 3 Generations

Founded on a family tradition that dates back to 1881, Marleau Mechanical Ltd. has been an integral part of the Cornwall community for four generations. Throughout the years, the Marleau name has acquired an enviable reputation in the commercial construction industry.

Our mandate is clear: to deliver quality work in a timely manner and at a fair price. These founding principles have allowed us to win most major bids and gain market share in Eastern Ontario. Despite the increasing complexity of our industry, we pride ourselves in getting the job done properly. Keeping abreast of technological changes is essential to remaining competitive, so we use only state-of-the-art equipment and employ an extremely well-trained staff.
