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. In 2023, Kevin, Nolan, and their father Pat realized a long-time dream — leaving their respective employers & leveraging their decades of earned experience 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 experience since the early 1980s. What we have found is that timeless principles — integrity, diligence, respect & humility — paired with technical aptitude set us apart.

Integrity
Fidelity to truth; in deed & word, even and especially when no one is looking. What we say is what we mean and what we build is what we promised.
Diligence
Uncomprosing work on projects that can't fail. We do the unglamorous as well as the glamorous, and we see it through to the end.
Respect
Everyone on the project is a person first: the owner, the nurse, the carpenter. We treat others' projects, time & work as belonging to them, not to us.
Humility
We listen without the need to be right, and we spend what we're good at on other people.

Why We're Different

Real builders. /h2>

The construction industry has a growing 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 project conception to the final paint, we're laser focused on the actual details needed to build your project.
