Southern Maine Commercial General Contractors & Home Builders

PATCO Construction has thrived since its inception in 1985, with the longevity of 4 experience-building decades that few other general contractors in Maine can match. Our construction company delivers comprehensive design-build solutions, encompassing planning, design, preconstruction, engineering, and construction right through to project completion. As a family-owned enterprise in Sanford, Maine, we have prospered under the leadership of Greg and Mark Patterson, the second generation of the Patterson family. Greg oversees the commercial construction division, focusing on custom metal buildings through a design-build methodology and self-performed erection. Meanwhile, Mark excels in designing and constructing residential homes, whether within company-owned developments or tailored to individual customer lots.

Both siblings and their team members embody the core values of integrity and collaboration, which permeate the entire organization. Both of the commercial and residential 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. If you’re searching for a residential architect, a new home builder, or a commercial general contractor specializing in custom metal buildings, Patco Construction is at your service in our local Maine and New Hampshire communities.
