What waterproofing costs
Across Australia, waterproofing typically runs $831 – $2,371 for shower waterproofing, and $550 – $1,843 for leak investigation.
Local prices vary, so these are typical Australia-wide ranges, not a quote for Western Australia. What you'll pay comes down to the size of the job, the condition of what's being worked on, and the finish you choose. Get a few quotes to see your exact number. It's free.
Things to consider before you book
The local conditions that shape the job, the best time of year to book, and what to sort out before you choose a waterproofer.
Seasonal Rainfall
Most of Western Australia gets moderate rainfall, so timing matters for exterior waterproofer work. Targeting the drier months gives the best run of uninterrupted days.
What's in a good Waterproofing quote?
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.
- 01Licence number
On the quote, and verify it before work starts.
- 02Compliance certificate
An AS 3740 certificate promised before tiling starts.
- 03Membrane brand
The exact membrane product, not just 'waterproofing'.
- 04Substrate preparation
Grinding, priming and levelling, so nothing is skipped.
- 05Number of coats
Liquid membranes need at least two coats.
- 06Flood testing
A 24-hour flood test before the tiles go on.
Cheapest isn't always the best. Check these before you hire anybody.
