  • “I hired Goncon to redo my kitchen, bathroom, living area and dining room, Jose did an excellent job in completing my projects, he was great about picking up materials, making recommendations about the latest trends, which was extremely helpful, and most importantly completing all the work on time per his estimated timeframe. Jose made sure I was completely satisfied with all the work that was done. I highly recommend and would definitely use him again for any major home project.”

    —Elena Foster

  • “Highly recommend GONCON. They did an excellent job helping us repair, restore, rebuild our bathroom after the condo above us flooded. Jose worked with on what needed to be done and give great advise and suggestions that we never would have considered without his insight and are so thankful we listened to him. The craftsmanship and professionalism of him and his team were exceptional. They were great guys who did fantastic work. I'm truly thankful we received their referral and hired them.” — RJ Dunn

  • “We were very pleased with the work done by Jose Gonzalez and his crew on our kitchen remodel. The quality of the work was excellent. Jose was very responsive to questions, showed up daily on the job, made useful suggestions and closely monitored the project. He is super easy to work with and the crew was delightful. I don't think you can go wrong if you hire Goncon Design & Build for your next project!”
