Our Story
Learn about our journey and how we became
a premier excavation company in the region.
Black Diamond Landworks was founded in 2022 with a simple goal: build a company centered around quality workmanship, reliable service, and a passion for shaping the land. After returning to the Flathead Valley from Spokane, WA, owner Mack brought years of experience working on residential, commercial, and public works projects, including road reconstruction, utility installation, site development, paving, and project management. Working under strict specifications and demanding timelines helped develop the planning, precision, and attention to detail that define our work today.
What started with a mini excavator and skid steer has grown into a full-service excavation and land development company with a skilled team, a modern fleet of equipment, and the capability to handle projects of all sizes throughout Northwest Montana. Today, Black Diamond Landworks proudly serves homeowners, builders, and developers across Kalispell, Whitefish, Columbia Falls, and Flathead County, delivering dependable solutions built on experience, integrity, and a commitment to doing things right.
