"What impressed me the most about Andrew was his uncompromising commitment to quality. It was evident in every phase of the projects he did for me and even more so in the final results."

"I first learned about Andy and Red Hammer through my association with Theatre in The Open at Maudslay State Park. Andrew is the facilitators manager there and does wonderful work. I wanted to put a shed in my yard and with Andrews artistic vison and building expertise he built a shed that looks more like a magical house in the woods than a shed. It is very well built, has wonderful storage features, and a small stage as a sitting area. It is not often that people visit your home and the first thing they ask about is your shed. Andrew has done additional work with us since then. Not only is he a master builder but he’s responsible, easy to get in touch with, and a delightful person to work with. I can’t say enough good things about Andrew and his work."
