Find trusted waterproofing contractors in Botany

"Need professional bathroom waterproofing in my [suburb/city, e.g., Sydney CBD] home. The bathroom is approx. 3m x 2.5m, including shower recess, floor, and lower walls up to 2m height. Currently stripped/prepped (tiles removed, surface ready for membrane application). Scope: - Apply high-quality waterproof membrane (e.g., liquid-applied or sheet system) to floor, shower walls, and junctions. - Seal all penetrations, corners, and wall-floor joins properly. - Provide waterproofing certificate of compliance upon completion (required for building regs/insurance). I can supply photos of the current state if needed. Materials can be provided or you quote including them—let me know your preference. Flexible on dates but ideally within the next 2 weeks. Looking for experienced, licensed waterproofers with good reviews. Please include your quote, timeline, and any questions in your offer. Budget around $800–$1,500 depending on exact scope (open to negotiation). Thanks!"
