Worth knowing: getting two or three quotes is the simplest way to land a fair price — and it costs you nothing.
Licence number. On the quote, and verify it before work starts.
Compliance certificate. An AS 3740 certificate promised before tiling starts.
Membrane brand. The exact membrane product, not just 'waterproofing'.
Substrate preparation. Grinding, priming and levelling, so nothing is skipped.
Number of coats. Liquid membranes need at least two coats.
Flood testing. A 24-hour flood test before the tiles go on.

Things that can impact your job
These factors affect waterproofing work in this area — worth discussing with your tradie.
Shorter Lifespan on Exterior Finishes
Botany is right on the coast — exterior surfaces and finishes typically last 5–7 years here, compared to 10+ inland. Coastal-grade products aren't optional when salt air is this constant.
Schedule Outdoor Work for Drier Months
Botany gets more rain than most areas — exterior waterproofer work benefits from scheduling in the drier months. Your tradie will work around the forecast, but booking ahead gives the best run of clear days.
Strata Area
Botany is predominantly apartments and units — body corporate approval is often needed before external work can start. Check with your owners corporation early in the process.
Body Corp Sign-Off May Be Needed
Botany is predominantly apartments and units. Body corporate approval is typically required before waterproofer work affecting common property, shared wiring, or building systems. Check with your owners corporation early — approval can add weeks.
Premium Finishes
Properties in Botany typically feature higher-end finishes and fittings. Ask your waterproofer about their experience with premium materials — the right techniques and products make a real difference with quality surfaces.
Your Botany waterproofing checklist
- Coastal-grade products for all exterior surfaces
- Book exterior waterproofer work for the drier months
- Check body corporate approval requirements
- Check body corporate approval before booking
