"Mandi and his assistant did a great job on our deck. He replaced the flooring, support post, and other elements that needed repair. He then sealed and stained, two coats each. All work was completed in 3 days! Mandi's professionalism and expert craftsmanship were evident in the final product. We especially appreciated how Mandi discussed details and consulted us about our preferences when changes to the original plan were needed. I highly recommend hiring Mandi."
