Who We Are

We’re the owners of the company — and we provide the work product. It’s personal.

Founded in 1996 as Constructech Inc., our company began as a family side business while careers progressed in the industry. In 2023, Kevin, Nolan, and their father Pat realized a long-time dream — leaving their respective employers to launch the company’s next era as Shaffer Building Company.

Our foundation, principles, and experience are derived from personally held values and decades of hands-on construction work since the early 1980s. What we have found is that timeless principles — integrity, diligence, respect & humility — paired with technical aptitude set us apart.

Integrity
We say what we mean and deliver what we promise — even when no one's watching.
Diligence
Saturday nights, Sunday mornings — we show up when the work needs doing.
Respect
Personal relationships over contractual ones. We earn trust, not transactions.
Humility
No egos. No bureaucracy. Just builders focused on your project.

Selected Projects

Real builders. Not brokers of contracts.

The construction industry has a problem: companies staffed with managers who've never picked up a tool. They react to problems instead of preventing them. Our team started as carpenters, elevator mechanics, and superintendents — we've been building since the early 1980s.

That applied experience means we plan construction to minimize problems before they start. We define scope beyond what's on the drawings, price the full reality of a project, and take responsibility from day one. No change order games. No surprises. From the foundations to the final paint, we're laser focused on the actual details needed to build your project.
