Serving Duncan and surrounding areas on Vancouver Island.
Duncan and the Cowichan Valley have a mix of rural acreage and growing suburban development. Land clearing, road building, and site prep for new builds are big parts of what we do here. Homeowners with established properties are also investing in retaining walls, drainage systems, and driveway work. The valley's mix of flat farmland and hilly terrain means every project needs to be assessed on its own.
Black Mountain Dirt Works is an owner-operated excavation and landscaping company serving Duncan and all of Vancouver Island. We work directly with homeowners and property owners on everything from backyard transformations to full site preparation for new builds. We try to approach every job the same way — carefully, and with the same attention we'd put into our own place.
