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.

Seasonal Rainfall

Cooler Months Give Better Results
