Generations of craftsmanship & honesty


Our story

His father is a very skilled carpenter, teaching him and working alongside him into his adult years. In 2005, he purchased Stambaugh Pole Buildings, erecting Pole Frame Structures. Since then, he has used his skills to expand the services he offers to include:

- Excavation of all sorts
