What they say

Michael & Suzi

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

Torch On mineralIn 2017 Forest Waterproofing was engaged to repair our flat membrane roof of 4-storey building in Kingsford and we were extremely satisfied with the work performed. Naoki’s service is professional, friendly and most accommodating. His attention to detail is outstanding. He even helped to fix and solved our TV reception problem which had troubled us for many years. We would have no hesitation in recommending Forest Waterproofing to anyone requiring the same service.
