Structural, civil, and general construction services supporting mechanical and process facility projects across Southern Ontario and beyond.
In addition to our core mechanical capabilities, Dunbar Mechanical Services provides a full range of civil and general construction services to clients across Southern Ontario. Our skilled trades personnel have the experience to take on structural, civil, and site work alongside mechanical scopes — streamlining project delivery, reducing contractor coordination, and keeping projects on schedule.
Whether it is site preparation ahead of mechanical installation or structural steel erection as part of a full facility build, we have the capacity and experience to execute the work to the same standard of quality as our mechanical services.
