Lake Oswego’s Trusted Deck Builder & Outdoor Living Contractor

Since 2005, GrassRoots Construction has been Lake Oswego’s trusted deck builder and outdoor living contractor. We began as a landscape maintenance company and saw the need for more intensive construction projects – today we specialize in custom decks, patios, and backyard living spaces across the greater Portland, OR area. Today we focus on low-maintenance construction and landscapes that are built with quality to outlast the elements. We have a team that has knowledge in all aspects of construction and we really enjoy what we do.

Founded in West Linn, Oregon, and now based in Lake Oswego, we build custom decks, patios, retaining walls, and artificial turf for outdoor living spaces throughout Lake Oswego, West Linn, Tualatin, and the greater Portland metro area.
