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.

  • 01
    Licence number

    On the quote, and verify it before work starts.

  • 02
    Compliance certificate

    An AS 3740 certificate promised before tiling starts.

  • 03
    Membrane brand

    The exact membrane product, not just 'waterproofing'.

  • 04
    Substrate preparation

    Grinding, priming and levelling, so nothing is skipped.

  • 05
    Number of coats

    Liquid membranes need at least two coats.

  • 06
    Flood testing

    A 24-hour flood test before the tiles go on.

Cheapest isn't always the best. Check these before you hire anybody.

  • Recent, genuine reviews

Frequently asked questions

Hiring waterproofers

How much do waterproofers typically charge?
Costs for waterproofing jobs vary depending on the type of job and its complexity. Area, access, the membrane system specified and whether remedial work or after-hours attendance is needed all influence price. This page shows live pricing for typical jobs to help you compare quotes.
Do waterproofers charge call-out fees?
Many waterproofers charge a call-out fee to attend and carry out an initial inspection, which covers travel and the diagnostic visit. Call-out fees are usually separate from labour and materials costs. It's wise to confirm any call-out terms when requesting a quote.
Do waterproofers need a licence in Australia?
Yes. Waterproofing work generally must be carried out by a licensed waterproofer in every Australian state and territory; in NSW, licences are managed by NSW Fair Trading. Providers should be able to supply their licence number and written membrane system specifications. It's common for reputable waterproofers to hold public liability insurance and for site workers to have a White Card.
Can I get an emergency Waterproofer in New South Wales?
Many waterproofers in New South Wales offer same-day and after-hours callouts. Get quotes from local waterproofers and ask about emergency availability when you book.

Using SureQuote

Is the SureQuote estimate a quote, and why can a tradie's quote be different?
No. Your estimate is a guide price for a typical job that matches your answers. A tradie prices your actual job in their quote, once they've seen things like access, condition, materials and the full scope. Read the full answer
What happens after I submit my job, and how many tradies will contact me?
We email you your estimate and a link to your job. Up to 3 local tradies can take it and contact you to quote; only they get your name, phone and email, and you choose who to hire, if anyone. Read the full answer
Is it free to get quotes, and does the tradie's fee raise my price?
Yes, getting quotes is free and you don't have to hire anyone. Tradies pay us a capped fee to take your job, and we set it before they quote, so nothing is added to your quote. Read the full answer
Can I add photos to my job?
Yes. Add up to 10 photos in the chat after you give your contact details, or later from the job in Hire, and tradies see them before they take the job. Read the full answer
Do I have to hire one of the tradies?
No. Getting quotes is free, you're never obliged to hire anyone, and you pay only the tradie you choose to hire. Read the full answer
Does SureQuote check tradies' licences and insurance?
We collect each business's ABN, licence, insurance and warranty details and keep them as up to date as we can, so you can see them in one place on its profile. We don't guarantee them, so always check the licence yourself on the relevant licence register before you hire. Read the full answer
