About RG Penfield & Sons

Our Story: A Legacy of Craftsmanship and the Next Generation of Builders

Since 1970, our family has built and remodeled more than just homes—we’ve built community trust, relationships, and a legacy of excellence. As a second-generation residential contractor now grooming the third generation, we are proud to serve homeowners in Greenfield, MA, and throughout Western Massachusetts with a dedication rooted in family tradition and community service.

It all began with our father, RG Penfield, whose passion for quality craftsmanship laid the foundation for what would become a multi-generational commitment to exceptional home building and renovation. He believed that a house is more than just walls and a roof—it’s a place where memories are made and where families grow. This belief was passed down to his sons Mark and Jason, who have grown the business and instilled the same standards of integrity, precision, and care.

As the current generation leading the business, we continue to uphold this tradition while actively mentoring and involving the third generation—our sons Mitch and Jason—in the art and responsibility of the craft. By blending time-honored techniques with modern innovations, we ensure that our family’s legacy not only persists but evolves to meet the ever-changing needs of our clients and community.

Whether we’re tackling full-scale renovations, exterior home improvements, home additions, ADU’s or small projects, we bring the same level of dedication and craftsmanship that has defined our work for decades. Choosing our services means more than hiring a contractor, it means partnering with a professional team that treats every home as if it were our own, using the finest materials and quality construction.

For more than 50 years, the Greenfield community and surrounding areas have come to trust in our multi-generational legacy.
