Balcony leaks show up in someone else's ceiling, which is why they become sectional title disputes before they become repairs.

Get a Balcony Leak QuoteWhere Balconies Fail
- The membrane under the tiles, especially where it was never turned up behind the door threshold.
- The door threshold itself, the single most common entry point.
- Blocked or badly positioned outlets, so water ponds instead of draining.
- The junction between balcony slab and building wall.
- Cracked screed and open perimeter joints.
- Failed handrail and balustrade fixings penetrating the waterproofing.
Sectional Title
In most Cape Town schemes the slab and its waterproofing are common property maintained by the body corporate, while the tiled finish is often the owner's. Get the entry point documented in writing before the argument starts; it decides who instructs and who pays.

Coating a balcony without correcting the falls means water still ponds, just on a newer surface. Ponding is what kills membranes, so drainage has to be fixed at the same time.

Frequently Asked Questions
Who pays for a balcony leak in a sectional title scheme?
It depends on the scheme's rules and on where the failure is. Slab and structural waterproofing are usually common property; the tiled finish is often the owner's. A written detection report identifying the entry point is what settles it.
Can a balcony be waterproofed without removing the tiles?
Often, with a liquid-applied membrane over the existing surface, provided the tiles are sound and the falls are correct. Where the screed is cracked or water ponds, the deck has to come up.
Why does it only leak in heavy rain?
Because the outlets cannot cope and water backs up above the threshold or the membrane upstand. That points at drainage and detailing rather than at the membrane itself.
