    We had a great experience working with Acton ADU on our ADU project, and I want to give a special shoutout to Sandro. Sandro was fantastic from start to finish—always professional, easy to talk to, and super responsive whenever we had questions. Sandro kept everything on track, paid close attention to detail, and made the whole process feel smooth and stress-free.

    Our ADU turned out exactly how we hoped, and we really appreciate the effort Sandro and the Acton team put into it. Highly recommend working with them!

    Building an ADU is a daunting task. Our Acton on site general contractor, Sandro helped us through the process literally from the ground up. His professionalism and guidance eased a lot of stress as we went through the process of this build that had many custom details. He is personable, answered our questions and followed through with many of our inquiries. He has great rapport with the on site workers and vendors and made sure the process moving along went smoothly. His expertise and experience are evident every step of the way. We appreciate his quick response and clear communication.
