I contacted KCB back in 2013 for an addition to my residence. My budget was tight but I found out that KCB was willing to work with me. Young gave me a few options on how to proceed with my project whilst being able to sign under my budget. We ultimately decided to hold off on the bathroom for the addition but still ran the necessary pipes and electrical wires into the space. By holding off on the bathroom for the addition, I was able to comfortably sign well below my budget. Since the piping and electrical wiring was completed during the addition, this gave me time to save in order to complete the bathroom at a more comfortable date. Having the wiring for the bathroom done during the remodel ensured that costs would be low once I decided to finish out the bathroom since no walls would be opened up. I truly appreciate Young and Victor's creative suggestion and success in keeping project costs in line with my expectations.

We hired Kim's Custom Builders to do a large remodel of our home, adding around around 900 sq/ft including family room, master bedroom, master bath, office and some remodeling of the kitchen. I would definitely recommend this company to my friends. We've worked with a few different local contractors but Mr Kim is the best used.

The quality of the work was consistently excellent with great attention to detail and was also delivered right on schedule. Mr Kim was extremely helpful and knowledgeable, he clearly explained all the design decisions and was very hands-on in all phases of design and construction. He was sensitive to keeping costs down by suggesting economic alternatives without compromising on quality.

Mr Kim also has his own cabinet shop so was able to build us some great custom cabinets at a reasonable price and match the color and construction of our existing cabinets.

We would highly recommend him and his crew."

Yay!! We're the first!

We hired Kim back in 2009 to build our new home in Cupertino. We went with KCB since they were extremely professional from the start. It took three days for us to receive our bid after the preliminary walk through. Having the bid line itemized helped us see the breakdown of cost per section and gave us confidence in their transparency.

Once we broke ground, Kim held weekly meetings to keep us up to date on the construction. They were also very knowledgeable when it came to questions regarding renovations or upgrades that would efficiently maximize my property value.

We pushed out our completion date by a few weeks due to our change orders but the project itself finished according to schedule. They even threw in freebies such as my lovely linen closet and in-wall ironing unit.

To say that my experience with KCB was enjoyable would be an understatement. Being able to choose from the abundance of different finishes made me feel like a designer! Maybe I can convince the hubby to do a light remodel this year

Victor if you're reading this say hi to the kids for me!

We've done several projects with KCB and we love them. Victor is very easy to work with and extremely reliable, which is a rare quality for a contractor. He's designed an entry cabinet for us and did some build-ins for our family room. He was willing to work with our tight budget and delivered everything in a very timely manner. Kenny and Luis were very thorough with the installation and also did a crown molding for us. We would definitely recommend KCB for their quality and reliability.

We would highly recommend him and his crew."
