While the sawmills get all the industrial glory for early Muskegon, none of these mills would have been able to operate long without support business such as The Muskegon Boiler Works. The boiler works provided crucial repair service to keep these sawmills running and built new equipment for many of the businesses and homes that would come afterwards. The company would at its height be constructing massive boilers throughout the United States and stayed in business until the 1980s.
