"They showed up on time each day, were very knowledgeable of the work they performed. Showed up for the quote when we scheduled the first meeting and we were very impressed with the overall experience. The deck they built was spot on and perfect for our needs. They did make some recommendations as to how it would look and work better for us and we went with their decisions and are so happy and impressed. They were very neat about their work and very easy to talk with. I would never use anyone else, and HIGHLY RECOMMEND them for whatever you need. So great to work with."

"I hired Barnett as the contractor for a bathroom remodel. We ended up doing much of the running around for materials and the project took more than 3 months and still did not get completed. It also cost significantly more than the original estimate do mostly to poor project management. I would not hire this company for another project."

"Overall, the finishing of my basement went pretty smooth. The Owens Corning product, drop down ceiling, and flooring are all really sharp. In the beginning everything went fast and smooth with the framing and wall/floor/ceiling install being done within 2 weeks. There were some hiccups with minor imperfections, tv mount in wrong spot, etc. Those were fixed promptly. After that is when I ran into issues with other items in my contract that were not taken care of and the project felt forgot about. Just had some minor electric work, stairs to get carpeted, and didn't receive hanging clips yet. I had to constantly ask about these items and every answer would be "I forgot to ask or send the clips". I eventually got the items completed, but am not happiest that it took almost a month and constant reminding to get these items that should've been scheduled for during the project."
