Who We Are

We are highly skilled craftsmen who value quality and attention to detail as the foundational principles of our business. But, our true core is communication. It’s what defines us. Communication is the structure that provides strength to our relationships.

Since we began in 1995, we’ve understood we are more than builders. We are partners with people who put a part of their future in our hands. The details, angles and sight lines create the space where lives are shaped and the future is created. We want to see that vision through your eyes before we begin to build. Good communication makes a measurable difference.

No two projects are ever alike and projects don’t always unfold as planned. Sometimes changes become obvious as the build takes shape. We’re sensitive to these issues and believe they are the reasons to stay connected throughout the process. We’ll talk in person or use the latest technology to look at the specifics together. We are schedule driven, because you are schedule driven. The sooner we are finished, the sooner your future begins.

The Rittenhouse Team

is comprised of people with diverse backgrounds and varied skills. Yet the common Rittenhouse DNA shared by all is our singular focus on craftsmanship and excellence. As a company we accept nothing less, and as individuals our team is never satisfied with anything less.

George Metzler

founding partner

When George founded Rittenhouse Builders he embraced the notion that construction was more than lumber and nails and tools. The building elements would generate more than walls and roofs; they would build a family’s dreams, the spaces where they would live and laugh and cook and entertain and carry on with their lives every day.

The seriousness of that responsibility required a rock-solid commitment to putting forth the absolute maximum effort and painstaking attention to every detail, all day, every day. George’s avocation is competitive long distance bicycling. He likens the discipline and focus required for that sport to the combination of short- and long-term perspectives needed to successfully shepherd a project from beginning to end.

George grew up on a dairy farm in Lancaster County, Pennsylvania. His parents worked hard on the farm, George learned early on what hard work meant, and that it took a team to make the farm work. George currently lives in Lancaster County with his wife and three children.
