What moves the number

Scope depth first — reseal, new membrane, or full strip and rebuild are three different jobs. Then access, which on a high-rise balcony can exceed the waterproofing itself. Then detail count: drains, upstands, planter junctions and balustrade fixings each have to be dressed, and each is a place a price gets made or lost.

Getting a real number

None of the bands on this page is a quote for your balcony, and no Gold Coast operator we checked quotes without seeing the job.
