We used Forest Waterproofing for a new extension at our home in Leichhardt. Naoki did an amazing job for us on our bathroom and upstairs balcony. The balcony was critical as it was incorporated into the roof situated directly above our new kitchen/dining area below. Naoki sealed it and made sure it was completely waterproofed as we were concerned and knew it needed to be done correctly. We have had huge downpours and torrential rain and have not had one issue with it. We would highly recommend Naoki and Forest Waterproofing. He was always courteous and very easy to work with and incredibly helpful and always left his work site clean and tidy. Michael & Suzi, Leichhardt
