    Hi, I’m Derek Pucci. I’ve spent the last decade swinging a hammer and honing my craft across every stage of the building process. I started in the trenches of new home framing and deck construction, learning exactly what it takes to make a structure solid and safe. Over the years, I’ve shifted my focus toward renovations and finishing work. I believe in honest work, clear communication, and craftsmanship that speaks for itself. If you have a project in mind, I’d love to help you build it right the first time.
