is at the heart of every project we build and is central to our story. PATCO Construction has thrived since its inception in 1985 and our longevity includes four experience-building decades that few other Southern Maine general contractors can match. It all began when Irving Patterson, a Sanford native, invited his son Mark to come work with him in new home construction. A few years later, son Greg joined as a third partner and helped PATCO expand with a commercial construction company branch of the business specializing in steel and metal building construction. Over the years, the Patterson family all worked together to build the business, with Irving’s wife Lorene, and three other sons helping out when needed. Irving never could have envisioned that his family-run business would become a pillar of the Sanford business community and a leader in Maine and New Hampshire’s construction industry. From the beginning, the Patterson family has focused on doing the right thing and PATCO became known as a Maine general contractor that always puts the customer first. The hard work and commitment to client satisfaction paid off and what started as a four-person company has grown into a team of over thirty construction professionals. As one of the most respected and trusted Southern Maine general contractors, we deliver comprehensive design-build solutions, encompassing planning, design, preconstruction, engineering, and construction right through to project completion. We remain a family-owned enterprise, and have prospered under the leadership of Greg and Mark, the second generation of the Patterson family. Greg continues to oversee the commercial construction division, focusing on custom metal buildings through a design-build methodology and self-performed erection. Meanwhile, Mark excels in new home construction, designing and constructing residential homes, whether within company-owned developments or tailored to individual customer lots. The values of teamwork and integrity are a part of our foundation and how PATCO Construction has been able to serve Maine and New Hampshire for over 35 years. Both Mark and Greg, as well as their team members, embody those core values which permeate the entire organization. As commercial general contractors and residential home builders, our teams demonstrate precise attention to detail and a commitment to surpassing client expectations. We collaborate with engineers, architects and subcontractors throughout the pre-planning, preconstruction, and construction stages to ensure our standards of quality are met every time.
