Balcony Waterproofing in Nundah
In Nundah the first sign of a failed balcony usually shows on the ceiling of the unit underneath rather than on the balcony itself — a painted soffit staining, from an original membrane sitting under a tiled floor. Townhouses complicate it: the balcony is typically inside the lot, but the structure holding it up and the membrane protecting what is below may not be the owner's to maintain.

Balcony Waterproofing around Nundah
Six in ten dwellings here are flats or apartments — 60.5% — with a further 15.8% townhouses and only 23.5% separate houses. Three-quarters of Nundah therefore sits under some form of shared ownership arrangement, which is what shapes who commissions a repair.
The older walk-up stock around the village carries the pattern this trade sees most in Brisbane: a concrete balcony with a painted soffit and an original membrane under a tiled floor. With separate houses at 23.5% of dwellings, Nundah has proportionally less of the pre-1946 character stock than Clayfield does, so Council's overlay comes up less often here and the body corporate question comes up more.
Permits and Brisbane City Council rules
Nundah's townhouse share changes the shape of the ownership question rather than removing it. A townhouse balcony is usually inside the lot, which tempts owners to treat it as entirely theirs — but Queensland Government guidance is that the body corporate remains responsible for "roofing membranes if the balcony provides protection to lots and common property below" and for structural maintenance of the slab, whichever side of the boundary the surface sits on. On the walk-up stock the same rule applies more obviously, since the balcony is plainly the ceiling of the unit underneath. Either way, QBCC requires a waterproofing certificate — Form 43 or Form 12 — once the work exceeds $3,300.
