Say whether the balcony is tiled and where water shows, and get quotes.
Get Waterproofing QuotesWhat Balcony Waterproofing Covers
- Membrane. A waterproof layer under or over the finish, turned up at walls and edges.
- Falls. Screed corrected so water runs to the drain or edge, not to the door.
- Door thresholds. Sealing where the balcony meets sliding or French doors.
- Drains and spouts. Outlets sealed into the membrane, not just to the tiles.
- Balustrade fixings. Bolt holes and posts sealed where they pierce the slab.
Signs the Balcony Is Leaking
- Ceiling stains. Brown rings or bubbling paint in the room or garage below.
- Loose or hollow tiles. Water under the tiles has broken the bond.
- White deposits. Efflorescence on grout, edges or the soffit.
- Ponding. Water that stands for hours after rain.
- Damp at the door. Swollen skirtings or flooring inside the doorway.
Methods and When Each Fits
- Tiles off, new membrane. The reliable fix when the original membrane has failed or was never installed.
- Clear sealer over tiles. A cheaper option for sound tiles with minor grout leaks. It does not fix failed membranes or bad falls.
- Liquid or torch-on membrane on untiled slabs. For exposed concrete balconies, often with a walkable coating on top.
- Detail repairs only. Thresholds, drains or balustrade fixings resealed when the leak is local.
The right method depends on an inspection and where the water is actually getting in.

Get Waterproofing QuotesWhat Affects the Quote
- Tiles on or off. Lifting tiles and screed adds labour, rubble removal and retiling.
- Size and shape. Small balconies have high fixed costs per m².
- Details. Thresholds, drains and balustrades take time to seal properly.
- Access. Upper floors may need scaffolding or rope access.
How the Work Normally Runs
- Inspection. The contractor checks falls, drains, thresholds and the ceiling below, sometimes with a water test.
- Scope. You get a written quote stating tiles off or over-tile, the system and the tiling.
- Preparation. Tiles and loose screed are removed, cracks repaired and falls corrected.
- Waterproofing. The membrane is applied and turned up at walls and the door.
- Flood test. Good contractors test before tiling.
- Finish. Tiles or a walkable coating go down and the drain is reconnected.
Preparation and Disruption
- Clear the balcony. Remove furniture, pots and braais.
- Door access. The balcony door may be unusable for a few days.
- Noise and dust. Tile removal is loud and dusty.
- Weather. Membranes and tiling need dry days.
Maintenance and Questions to Ask
- Keep drains clear. Leaves and dirt block outlets and cause ponding.
- Check silicone yearly. Reseal joints at doors and walls when they crack.
- Ask. Is the quote tiles off or over-tile, and why?
- Ask. Will you flood test before tiling?
- Ask. What written guarantee do you offer, and what voids it?
Balcony Waterproofing FAQs
Can a balcony be waterproofed without lifting the tiles?
Sometimes. A clear sealer can help with sound tiles and minor grout leaks, but it will not fix a failed membrane or poor falls.
How long does balcony waterproofing take?
Small over-tile jobs can take a day. Tiles-off work with retiling usually takes several days, depending on drying times and weather.
Why does my balcony leak at the door?
The membrane often stops short of the threshold or the door frame was never sealed into it. This is one of the most common leak points.
Will the new tiles match?
Not always. Ask the contractor about available tiles before the old ones are lifted.
Do I need a flood test?
It is good practice. Ponding water on the membrane before tiling shows whether it holds.
