Mainstream Mechanical Ltd

Mainstream Mechanical Ltd operates as a general contractor headquartered in Grand Forks, Washington, with a project footprint spanning British Columbia, Alberta, and multiple American states. Incorporated on 13 January 1981 by Philip Novokshonoff, the firm has built its reputation exclusively on commercial, institutional, and industrial work rather than residential service. The company holds coverage across Grand Forks, surrounding areas of Washington, and extends throughout BC and Alberta, though prospective residential customers should confirm service scope before calling.

What distinguishes Mainstream Mechanical is their vertically integrated 'from the ground up' capability, handling everything from initial engineering through underwriter approval, startup, commissioning, and ongoing maintenance. Their crew combines over 80 years of specialized piping knowledge across a small core team, allowing them to tackle cross connection control and testing projects requiring the most current equipment and procedures. The firm maintains commercial certifications for fire protection, industrial gas installation and service, and carries Caterpillar and JLG heavy equipment for large-scale jobsite deployments, positioning them distinctly against contractors who subculture major scopes.
