Sydney Waterproofing FAQs
Common questions about waterproofing in Sydney and NSW
Waterproofing costs in Sydney typically range from $800 to $5,000+ depending on the scope. A standard bathroom costs $1,500 to $3,000, while large commercial projects can exceed $10,000. Costs vary based on area size, membrane type, access difficulty, and whether it is new construction or remedial work. We'll pass your enquiry to a local contractor for a free quote.
Yes. In New South Wales, waterproofing work valued over $5,000 requires a contractor licence issued by NSW Fair Trading. Before you book, check the contractor's licence on the NSW Fair Trading register and ask for a certificate of currency for their insurance. You can verify any contractor licence at the NSW Fair Trading website.
A typical bathroom waterproofing job in Sydney takes 2 to 4 days, including surface preparation, membrane application, and the mandatory 24-hour curing period before tiling. Larger projects like balconies or basements may take 5 to 10 days. Weather can affect external waterproofing timelines, especially during Sydney's wet season.
AS 3740-2021 is the Australian Standard for waterproofing of domestic wet areas. It applies to all bathrooms, showers, laundries, and other wet areas in residential buildings across Sydney and NSW. Compliance is mandatory under the National Construction Code. Ask your contractor to confirm their work will comply with AS 3740.
Common signs include water stains on ceilings below wet areas, musty odours, peeling paint, bubbling tiles, damp or discoloured walls, efflorescence (white salt deposits) on masonry, and visible mould growth. If you notice any of these in your Sydney property, we recommend getting a waterproofing inspection before damage worsens.
