"Geo and his workers were professional and kind and added unexpected touches that made our new screened in porch especially beautiful and safe for older people. We also explained about the unusable height of our dog when he stands on his hind legs, and put in the best pet screen everywhere. We were surprised at how quickly they worked, but the quality is wonderful! Couldn't do better. Visitors love it."
"I have to admit that without any personal referrals I was a bit hesitant to hire them for the job, but I had a very good feeling about the company so I hired them for part of what I wanted done. I am SO HAPPY I did!! They were amazing!! They showed up on time, and all their team members were very respectful. I was immediately impressed!! Throughout that part of the project I continued to to be impress with their knowledge, work ethic, and integrity. In the end, that part of the job was beautiful and perfect!! I could not have been happier!!"
