We have been married for 30 years. In those 30 years, we have lived in four different homes. Two homes were rented and one was an older home that was remodeled. 


This was our very first new home and new build. The process went smoothly from day one. Any changes, from floor plan to colors, were met with an "okay" and a smile.


Everyone on the project was knowledgeable and professional. Thank you Castle's Custom Homes. We love our new home.
