What our clients say

Jason is extremely professional and I would highly recommend him to anyone!

Emmalea Johnston Jonesborough, TN

We were very pleased with how efficient and knowledgeable he was. Our project was done in a good timely manner, and even 5 years later we are still extremely pleased.

Traci Stone Johnson City, TN

“When we decided to build a new home, we interviewed three different builders and chose Jason Day. He was the only one who had the knowledge to take our blue print and make changes to fit our wants and needs. He made major changes to our roof line by adding a large screened porch and extended length and depth to enlarge certain areas in the interior. We wanted a very upscale look to our interior with custom mouldings, extensive trim work, coffered and trey ceiling, large custom shower in master suite, large custom mirrors in baths, farm sink in kitchen with island and gas cooktop with large vent fan . He designed all of these and advised us to different products to make our home as maintenance free as possible. He built us a beautiful home and if you are looking for a builder that is knowledgeable, dependable, honest and up to date with all the latest trends than we highly recommend Jason.”
