"Gene and his crew did a great job on a difficult project. The house is over 100 years old and had been renovated several times in the past. Gene’s strength is to work collaboratively with his client to ensure the project meets the customer’s expectation. This project changed a couple of times based on what we found during demolition. Gene provided options and was always upfront about the cost of each option. We set out a schedule and the crew showed up on time for the day and on schedule for the week. I am very happy with the work."
