Balcony Leak Warning Signs to Check After Rain
What staining, failed joints and surface deterioration can tell you about a tiled balcony.
Start with the symptom
Balcony leaks often become obvious after rain, but the stain below may be some distance from the actual entry point. Water can travel through joints and interfaces before it becomes visible.
What the condition can mean
Warning signs include deteriorated grout, failed perimeter joints, cracking, water sitting near thresholds and staining to ceilings or walls below. Outdoor exposure means these areas deal with sun, rain and movement.
Choosing the next step
Photograph both the balcony surface and the area where moisture appears. That context is useful when deciding whether targeted regrouting or sealing is appropriate, or whether a broader waterproofing scope needs consideration.
