He has a great team who helped us remodel our kitchen. Francisco was awesome! We decided to go with Nick because he is knowledgeable and was able to answer our questions. For instance, during the initial consultation, we had questions about removing kitchen soffits… Nick literally took out a hammer to see if they were removable or not and told us the cost upfront. We are already having Nick come back to help us with another project. We highly recommend Nick and his team!
