We requested to have our 5x8 bathroom remodeled. Quincey responded to my message right away and showed up the next day to view the bathroom and give an estimate. He was very fair with the pricing and also honest about what to expect. This was our first remodel experience and it was beyond what we expected. The subcontractors were all very professional and talented. Quincey was instrumental in guiding me on design choices (he's got a great eye). The most impressive was the fact that they finished a day early!! We were so impressed with the workmanship and final product that we booked another project with them!

Great job from start to finish. We contracted them to remodel our primary bathroom. They gave us a good estimate and stayed within the budget. Very responsive via text and throughout the entire remodel. All of the sub-contractors were easy to work with and did a great job. Would definitely hire them again to do any remodel work.

Castillo RemodelZone did an amazing job on my bathroom restoration! Quincy and his entire team were very professional, friendly, and responsive. They were all very patient and knowledgeable when answering my many questions and responding to any concerns that I had. They also provided a cleaning service after the restoration to cleanup any debri that was left behind, which left everything spotless and smelling clean and fresh! I definitely plan to use Castillo RemodelZone's services again for future projects! :)

Michelle and Quincy Castillo were amazing to work with from start to finish. I had a really bad experience with the previous contractor and they definitely made what I envisioned come to life beyond any of my expectations. They quickly came in made a plan and everything happened on time as planned and they finished off my guest bathroom and the primary bathroom. Michelle and Quincy were personal and professional and went above and beyond to meet my expectations. I would highly recommend that anybody use them for whatever you need. Fantastic experience! I even feel like I gained a couple of friends and Quincy and Michelle.
