Columbia Excavation did an outstanding job. Their pricing was very affordable compared to other quotes I received, and the quality of their work exceeded my expectations. The crew was professional, hardworking, and respectful throughout the entire project. Everything was completed efficiently and the results were excellent. I would highly recommend them to anyone looking for reliable excavation work.

This team did a sewer line replacement for me that was not a normal replacement. There were many obstacles they had to overcome and they handled them quickly and professionally. Very easy to work with.

Thanks for the service. As for the payment, the guy asked me for payment as soon as they finished the job by mentioning a verbal invoice amount. I gave him my credit card payment but still did not receive any official invoice. Will you send me invoice? I paid already. Joseph/509-863-6***.

We recently worked with Columbia to redo bathroom tiles from our remodel that was done last year. In the original bathroom remodel we had concerns about how the tiles were laid (they didnâ t lay completely flat). Columbia was very responsive to our concerns, they scheduled a time to come back out and assess the job, and ultimately ended up redoing the tiles in both bathrooms. Weâ re so glad they did! Once they opened everything up, we became aware of few other issues that needed to be addressed. The team from Columbia were diligent about correcting any issues that arose and went above and beyond to make sure we were happy with the end results. We now love our bathrooms and would highly recommend the team at Columbia Contractors!

Did a good job hooking up my sewer but ruined my backyard in the process. The credit they gave to my account wont cover the repair costs.
