Gas Conversion you can actually trust
Converting an open wood fireplace to gas means more than dropping in a log set. We run and pressure-test the gas line, install the appliance, and vent it correctly — B-vent through the existing masonry flue with a listed liner, or direct-vent through the wall.
Every Grimsby technician is WETT SITE-Basic certified at minimum, with two inspectors carrying full SITE-Comprehensive credentials.
