As a master builder, building extraordinary homes for my clients, I depend upon the expertise of my subcontractors. Coffman Excavation has proven over the 15 years that I have worked with them to be professional, trustworthy and dependable. I have found that Coffman’s ability to research and the fact that they are well regarded with the county building officials have been beneficial to my company. I would highly recommend Coffman Excavation and consider Coffman Excavation to be a significant member of my team.”

“We have worked with the Coffman Excavation team on many of our larger on-site wastewater treatment systems projects. We can recommend them to any of our clients without hesitation, and always include them on our invitation to bid lists. We find Coffman’s pricing competitive, their installations quick, well built, accurate to our designs, and with excellent communication and follow up from the preconstruction meeting through system start-up to site clean-up and finish work. [...] They definitely make our designs look as good on the ground as they do on paper.”
Robert F. Sweeney, President, Environmental Management Systems, Inc.
