What Orange County Homeowners Say

Cutler Construction was the contractor for a major renovation (floors, redesigned kitchen, bathrooms, etc.) of our home and I highly recommend them. Josh and his team were good to work with, communicated well and, most importantly, did high-quality work and took pride in doing great work. We had never done anything like this, but Josh was patient about guiding us and helping us choose fixtures, appliances, colors and the many other things that must be decided when undertaking such a large project. He also made some of our ideas happen, going above and beyond to make sure things turned out as we wanted. We have been showing our place to friends and several, including a retired contractor, have made unsolicited comments about the high-quality workmanship. We continue to marvel at the results and how much our home has been improved.

Cutler Construction did an amazing job on remodeling our 2 bathrooms. When we first met with Josh, we tasked him with taking 2 smaller bathrooms: enlarge them, add double sinks, and maximize the space. This was a challenging task, but the result turned out beautiful and beyond our expectations. The crew was always courteous and professional, they cleaned up at the end of each work day. Josh always answered our questions and gave us solutions when needed. He continually gave us updates on work being done each week. There were never any issues with inspections or obtaining permits because the work done was professional and without shortcuts. It is difficult to find a company that shows integrity. We are thankful for our experience with Cutler Construction.
