Meet Nathan Casey

Since I founded KC Custom Builders in 2006, my goal has been to provide discerning clients with a remodeling or new build experience that is better than the rest. Over the last 14 years, I’ve worked with some amazing people from various backgrounds, helping dozens of families create their dream home.

Remodeling your home or building a new home is a significant investment of your time and money. You want to be certain that the contractor you choose to build your dream home is honest and reliable. You want someone who cares about more than just your service, someone who wants to get to know you.

When I ask people why they choose me over other contractors, they often tell me it’s because of my personality. I invest a lot of time in getting to know people before starting on their project. We’ll talk about your career, your family, your interests, or whatever else comes up. My goal is to connect with each of my clients. We’ll be spending a lot of time together, so making sure we’re the right fit for each other is key to a successful project.

When all is said and done, and your dream home is complete, I hope to be more than just your business partner, but also a lifelong friend.

KC Custom Builders did an awesome job with our 3 months long kitchen and family room remodeling project. What impressed us the most were * their impeccable attention to details when it comes to the quality of their work: they caught more imperfections before the final walkthrough than we did; * great coordinations with suppliers: they went the extra distance to overcome mistakes made by suppliers; * super nice people: we really enjoyed interacting with their employees and contractors. We highly recommend KC to anyone.

I would highly recommend Nathan and his staff at KC Custom Builders for any home construction project. We hired them for a primary bedroom, bath closet project in 2023 and would use them again for any further projects. Nathan was organized and efficient. The technology app they use made the communication and process regarding progress and adjustments seamless. Nathan and his team were courteous and easy to have at our home at all times. They even went above and beyond in helping us with an unrelated water leak! The final project is beautiful, high quality and is exactly what we envisioned and more. I would hire them for any house project in a heart beat.

KC Custom Builders did an outstanding job on my kitchen/bath/living room remodel. They were professional and easy to work with.

We have done two significant kitchen remodels with KC - the first in 2019 and the second in 2023. In both cases the work was done with care and the results were excellent. The unexpected things which always turn up in remodels were dealt with honestly and fairly. We would recommend KC without reservation if you want a high quality job done.

I would like to thank KC Builders for all their due diligence, As a professionally run contractor. As a subcontractor I have been with KC Builders for about six years, Nathen is very adamant about schedule and quality of workmanship Which I respect myself. I have seen Nathen go above, and beyond even at his cost To make the project come out to his satisfaction. I would seriously consider to all consumers to proceed with KC Builders. When completed with your project, you will know you made the right choice Michael with Creative Drywall

We engaged with KC Custom Builders, specifically Nathan Casey, as one of several contractors we were considering for our project. They did not end up fitting our needs for this particular project, but we are eager to work with them in the near future. Going through the budgeting process with them was extremely valuable. They were knowledgeable, responsive, and detailed. The communication was thorough, candid, and extremely helpful. Additionally, we were able to visit one of their finished projects and were extremely impressed with the quality of work. The owner was very complimentary of their experience - any issues that arose (as they do in construction) were always addressed to their satisfaction. This was our first time remodeling and working with contractors and Nathan was proactive in considering what we should know and what would set up our home for long-term durability. It was clear to us that they would have ensured a high quality of work and had the best interest of our home in mind.

KC Custom Builders did an extensive remodel of our kitchen in mid-2019. The result was great and we hit our budget and (almost) timeline despite some of the surprises that always come with this kind of project. Nathan, who personally managed the project for us, was outstanding to work with, managed the subs beautifully, and rolled up his sleeves when needed to stay on track. We also want give a special shout out to Jesse who was the lead on the construction work. He was reliable, courteous, professional, and did excellent work. We are delighted with the result and, while a remodel is always disruptive, KC Custom made it a very positive experience.

Working with Nathan Casey was an absolute pleasure. He is extremely skilled, pays careful attention to every detail, and employs sub-contractors that share his enthusiasm for craftsmanship. I have many friends who were not so lucky with their contractors and suffered through their projects. The experience with Nathan was exceptionally positive. He estimated the budget very accurately and kept to it. I highly recommend KC Custom Builders.

KC Builders did an excellent job on our Condo in Berkeley. They full remodeled two bathrooms but when we removed the walls we found significant dry root in both bathrooms. They worked with the city to get new permit requirements meet and were very clear on the work to be done to fix this and the cost. Berkeley permit department was very difficult in all aspects but KC Builders handled this very professionally and shielded us from them. In the end everything was perfect, the city was happy and my wife and I were very happy.
