Get a quote

Tell us what needs waterproofing.

We will book a site inspection, diagnose the leak or check the wet area, and send back a by-the-m² quote split into clear lines, named to the Standard, so you can see exactly what you are paying for and compare it properly against anyone else. Want a number sooner? Send a photo of the stain or the bubbling tiles and we will give you an indicative price first.

Fast and free

Send a few photos of the stain or the bubbling tiles for an indicative price and a faster diagnosis before we even visit, then a call or text back within one business day. Free and no obligation.

Itemised, not a round number

A by-the-m² quote that names the area and the Standard it meets, the membrane system and the coats, the prep and any strip-out, the flood test and the certificate, with QBCC 0000000 on it. No surprise figure at the end.

Named to the Standard

AS 3740 inside a wet area, or AS 4654 outside on a balcony, deck or roof, on the page, so you can compare our quote like for like against anyone else.

No surcharge nearby

    What you will get back

    What an honest waterproofing quote itemises.

    The 7-line quote
    1. 1 The area, by the square metre. The price broken down by the m² and the area, not one round number for "the waterproofing". A shower recess, a bathroom and a balcony are different jobs, and the quote should show it.
    2. 2 The Standard it has to meet. AS 3740 inside a wet area, or AS 4654 outside on a balcony, deck or roof, named on the page. The Standard is what sets the coats and the detailing, so naming it is the honest part of the quote.
    3. 3 The membrane system and product. Cementitious, liquid-applied or sheet, and the actual product named, not "we will seal it". The system is chosen for the exposure and the substrate, and you should see which one you are paying for.
    4. 4 The number of coats. How many coats, because the most common cheap shortcut is one coat where the Standard needs two. It is invisible the moment the tiles go down, so it belongs on the quote.
    5. 5 Prep and any strip-out. The substrate prep, and the strip-out of failed tiles or membrane where it is needed, as their own line. Prep is a real cost before any membrane goes down, never folded into a round number.
    6. 6 The flood test and certificate. The flood test that proves the membrane holds water, and the compliance certificate a licensed waterproofer issues. The test is the difference between it looks done and it is proven.
    7. 7 The membrane warranty. The 10-year membrane workmanship warranty in writing, alongside the manufacturer system warranty. The cover a cheap operator will not put on paper, because they cannot stand behind a rushed job.
    If a quote doesn’t show these lines, you can’t compare it, and you don’t know what’s been cut.
