Balcony Waterproofing prices in Sydney
This page publishes no price band, and the reason is worth stating plainly: a survey of the six businesses competing for this work in Sydney found no published figure on any of them, so any number here would be invented rather than sourced.

This lists each source's own lines as read; it is not legal advice, and it sets no price. The value that counts is the value of the work, including materials, labour and GST.
What moves the number
Four things, roughly in order. The area of the balcony. Whether the existing tiles have to be removed, which the Sydney market genuinely disagrees about and which depends on the condition of the bond underneath. Whether the falls have to be corrected rather than just re-membraned, since that is structural work rather than a coating. And access — on an apartment building, getting materials and people to a fourth-floor balcony can cost more than the membrane on it.
How you get a real figure
Someone inspects the balcony, taps the tiles, checks where water actually sits, and looks at the outlet and the door threshold. That produces an itemised scope you can compare against another quote. A number given over the phone before any of that is a guess with a decimal point.
