"Great service, work, and people. Highly recommend for small or larger jobs."

"Great experience working with everyone on the team and the pole barn turned out great. Thank you!"

"Got three bids from excavation companies for a residential dig out on a 5 degree sloped property. The two we didn't go with took the run of the mill approach. If you looking for an excavation team that has vision and can provide you with options outside the norm, I highly recommend this group. Ryane and team are complete professionals who are in the business to work for YOU with focus on providing an end product that meets your expectations. The team is quick to respond, kept communication on the forefront everyday during the project, and provided us with invaluable advice with the build as a whole. There was never any guess work or lack of communication. We could not be happier with the support we got from them."

"Columbia Groundwork replaced a sewer line at our commercial building. I used their website to contact them, the response was fast. They were able to handle every detail of the project and made valuable suggestions. There was minimal disruption and they were very professional. I would highly recommend Columbia Groundwork."

"Columbia Groundwork provided conduit excavation services to bury overhead power lines and resolve water drainage issues at our residential home in the historical neighborhood in Longview, WA. Ryane and his team were very professional and caring to ensure that the work was done correctly and that the best choice was made. All work was done in a timely matter. We would gladly do business again with Columbia Groundwork."
