About Sentinel Builders

Since 1997, Sentinel Builders, Inc. has been building quality homes in East Tennessee. Gary Duncan, President and Founder of Sentinel Builders, grew up in the industry and saw an opportunity to help future homeowners combine their basic need of shelter with functionality, design, style and value. With over 20 years of experience, he has surrounded himself with a team of dedicated professionals committed to building a company on the foundation of security and excellence.

We have built hundreds of homes since 1997. We have also created communities like Plantation Springs (the 2005 Metropolitan Planning Committee Excellence Award Community), Creekside Plantation, Hannah’s Grove, Copperstone, Turnberry, Chanterelle Glen, Joshua’s Landing and Cherrybrook. Our custom homes, semi-custom, condominums, and villas incorporate efficient products and exemplary craftsmanship.

As a Licensed Contractor, we work with craftsmen, subcontractors and vendors who share the same commitment to excellence we seek. We are proud of the relationships we have in the community and in the industry. Providing you with the right products and services is our goal.
Most importantly in every project, we value each of our homeowners. This is afterall, your home. We value the time it takes to listen to your needs and answer your questions at every stage of the process. If you are interested in building a custom home or joining one of our neighborhood communities, we look forward to hearing from you and providing you an overview of our services.
