"The team at Copperhead helped us build a garage from start to finish. They were extremely helpful in working with our suggestions and what we wanted, and pointed out things that we didn't even think about. Their employees were there on time and always friendly. The owners/managers were always available to help with any questions we had and so were their workers. This all took place during the busy storm season, and while I'm sure they were busy with other jobs, they made us feel like we were the most important."
