The detail
What a good waterproofing quote includes
A good quote spells out how the job is priced and what's covered — labour, materials, prep and clean-up — so you're comparing like for like. Check what each waterproofer's quote covers before you choose.
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.
Heritage Presence
Sydney has a strong heritage presence — some properties may have restrictions on exterior changes. If your property is older, it's worth checking with council before starting exterior waterproofer work.
Salt Air Exposure
Sydney is close enough to the coast for salt air to noticeably shorten the life of exterior finishes. Coastal-grade products are strongly recommended — standard options won't last as long here.
Schedule Outdoor Work for Drier Months
Sydney 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
Sydney 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
Sydney 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.
Your Sydney waterproofing checklist
- Check heritage status with council if property is older
- Coastal-grade products for exterior surfaces
- Book exterior waterproofer work for the drier months
- Check body corporate approval requirements
- Check body corporate approval before booking
