7 Signs of Balcony Water Leakage
- Peeling or bubbling paint
- Mould and mildew growth
- Persistent damp or wet areas
- Cracks in balcony walls or floor tiles

If these signs continue after rain or washing, arrange an inspection to identify where the water is entering before carrying out the repair.
What Causes Balcony Leaks?
Damaged or Worn Waterproofing Membrane
An old or damaged waterproofing membrane can allow water to penetrate the balcony surface.
Cracked Grout or Damaged Tiles
Cracks and gaps around tile joints can allow water to pass through the tiled surface.
Poor Drainage and Water Pooling
Blocked or insufficient drainage can cause water to remain on the balcony floor for long periods.
Cracks in the Concrete Slab
Cracks in the concrete slab can allow water to seep into the structure below the balcony.
Failed or Poorly Applied Waterproofing
Waterproofing can fail when the system is unsuitable for the area or has not been applied correctly.

Our team will inspect the affected area and recommend the repair or waterproofing method based on the source and condition of the leakage.
