Ensure Waterproofing asked me to write a review for them for the balcony they waterproofed in Point Frederick. Ensure waterproofing has exceeded my expectations of tradies by being on-time, and delivering exceptional workmanship using their sheet membrane. Previously I had water coming into my living room from my balcony and sliding doors and now...nothing! Thank you!
