Working with KC/Nathan has been an incredible experience from start to finish. They are truly professional and exceptionally organized, which made the entire process smooth and stress-free. Their team consistently showed up on time, worked extremely hard, and kept the job site spotless throughout the project. What stood out the most was how much they truly care about their clients and the quality of their work. Every detail was handled with precision, and they went above and beyond to make sure everything was done right the first time. Communication was clear and consistent, which gave me peace of mind during the entire process.

The only regret you’ll have is choosing someone else.
We recently had KC Custom Builders remodel our kitchen and family room and we couldn’t be happier with the results! They were top notch: experienced, talented, and a pleasure to have in our home over the duration of the job. The Subcontractors chosen by Nathan Casey were similarly reliable and talented. Nathan, himself, was here frequently, supervising and readily available to answer questions and explain the progress of their work. Job tweaks along the way were handled quickly and priced fairly. Daily cleanup and dust control couldn’t have been better. We strongly recommend KC Custom Builders and we would not hesitate to call them again for a new project.
I worked with Nathan and the team at KC Custom Builders on a home remodel, including a major kitchen renovation, and the experience was fantastic from start to finish.The crew was skilled and respectful, the subs were top quality, and the attention to detail was spot on — which, as a designer, I really appreciated. Nathan kept everything organized and running smoothly, and communication throughout was clear, responsive, and collaborative.The process felt easy, and the results speak for themselves. The clients are thrilled, and so am I. I’d gladly work with Nathan and KC Custom Builders again and highly recommend them.
Nathan and his team did an incredible job on our full home renovation! We took our 1950s house down to the studs, added 600 square feet, and completely transformed the space into our dream home. Nathan was fantastic to work with—professional, communicative, and truly invested in bringing our vision to life. His crew and the subcontractors he hired were all top-notch, skilled, and respectful throughout the entire process. Even years later, we continue to appreciate the quality craftsmanship and attention to detail in every corner of our home. We couldn’t be happier with the results and highly recommend Nathan to anyone looking for a reliable and talented contractor!
