Petrin Mechanical began nearly 60 years ago with one man, Norm Petrin, under the name Norm Petrin Plumbing & Heating Co Ltd. At first it was just a man and a truck, but as time went on it grew to include his 3 sons, Norm Jr, Dan and Gilles, all of whom dug ditches side by side with their father, a fact they will all tell you contributed to the incredible work ethic they all share.

With 60 years of history and experience behind us, Petrin Mechanical (Alberta) Ltd continually strives to ensure a top quality product and service to all of our clients at a fair market price. We take great pride in surrounding ourselves with first rate employees, subcontractors and suppliers who have contributed to the overall success of Petrin Mechanical (Alberta) Ltd.

The Petrin Mechanical (Alberta) Ltd. family has remained an adaptive, cost conscience, innovative and moral company. With years of resources, we have the knowledge and means to take on any project. Petrin prides itself as a ‘Can Do’ and relationship based company that will provide a positive experience as part of your Construction Team.
