About

O'Brien Fabrications Ltd. is a Full-Service Metal Contractor servicing Guelph, Kitchener, Waterloo, Cambridge and surrounding areas since 1989. We specialize in custom metal fabrication, welding, commercial HVAC, and metal roofing and siding projects.

Started by Mike O’Brien and Bill Green, O’Brien Fabrications opened its doors for business in Guelph in July, 1989, with 2 employees, 1 pickup truck, and a 1000 square foot shop to work in. At that time, the primary source of business was supplying and installing metal roofing and siding work for Wm. Green Roofing Ltd., our partner company. Gradually, our business grew to include metal siding and roofing, all types of HVAC work, CWB certified welding and fabrication, as well as specialty metal projects. Today, we are a thriving company with approximately 30 employees, and an 8000 square foot shop which includes welding, HVAC, and metal roofing and siding departments.

We are fully insured, WSIB certified, and able to offer tender and performance bonding if required. We take pride in working safely and providing our employees the training they need in order to do their jobs effectively.

Whatever the project, we are committed to meeting and exceeding the needs of our customers. We are proud to have been in business for over 30 years, and believe in doing things the right way. Let’s get to work!
