What Patco Construction does

Patco Construction is a family-owned design-build general contractor headquartered at 1293 Main Street, Sanford, Maine, founded in 1985 by Irving Patterson with his son Mark. The company operates two specialized divisions: Patco Residential, which delivers new home construction, custom and pre-designed homes, woman-centric home design, waterfront construction, and build-on-your-lot services; and Patco Commercial, which focuses on custom metal buildings, steel roofing, commercial renovations and expansions, and commercial building repairs. Under second-generation Patterson family leadership — Greg Patterson overseeing the commercial/steel division and Mark Patterson leading residential construction — PATCO employs a design-build methodology spanning planning, design, preconstruction, engineering, and construction, with self-performed steel erection via an in-house Steel Crew on commercial projects.

The company's go-to-market is direct and sales-led, primarily through its headquarters phone line and three web properties (patco.com, patcohomes.com, patcocommercial.com) that route prospects to the appropriate division. Revenue is generated project-by-project via custom-quoted contracts; pricing is not publicly disclosed. The customer base consists of residential homebuyers and commercial property owners across Southern Maine and New Hampshire, with no named-logo or project-level revenue disclosures in available materials.

PATCO has grown from a four-person operation in 1985 to a team of over 30 construction professionals. It remains under family ownership with no external investors, no disclosed funding rounds, no acquisitions, no software platform, and no disclosed AI/ML capabilities. The operating model is that of a traditional regional construction services firm differentiated by longevity, family-brand reputation, niche specializations (waterfront, woman-centric design, metal buildings), and in-house steel self-performance on the commercial side.
