Jeff Hamilton
We are the proud owners of a beautiful custom home built by KC Custom Homes. From the initial meeting with the architect to help design our dream home to selecting our tile, paint colors, stone and light fixtures, the whole process was personal, professional and so easy flowing.  We are so happy with the attention given to us personally by all the Castro family and their employees. Our home is beautiful and we love everything about OUR CUSTOM home, it is perfect!!

Jamie Garza
We had a fantastic experience working with KC Custom Homes. The entire process was comprehensive. The sales team, Chris, Cameron, and Rudy were incredible. They sat down with us, thoroughly provided us with step-by-step details of their process, and were professional and very responsive in answering our questions. Then they provided a warm handover to their operation team Ryan and Shawn (Project Manager). These two gentlemen were true professionals. They hand-carried us through the groundbreaking to the final walk-through inspection. Their professionalism and assistance helped minimize some of our stress, which we were grateful for! We genuinely enjoyed working with KC Custom Homes and appreciate everyone involved in making our dream home come to life.
Geoffrey Dean
KC Custom Homes built our beautiful dream home and we are enjoying every bit of it!  When we started the process, we had about 4 builders lined up to meet with initially.  KC Custom Homes was our first  and last builder that we met with.  After meeting with the owner, his designer, the project manager and other staff members we knew then that we didn't need to look any further because KC Custom Homes was the best builder out there to meet our needs.  KC Custom Homes made our building experience like winning the lottery!
