Our History.

Quast Excavating was founded in 1980 by the late Garry Quast. The company started as a small residential excavation operation within the Manotick area, and by the early 2000’s it became a joint father son operation that expanded across the Ottawa South area. Quast Excavating is now proudly owned and operated by Eddie Quast.
