Confirmed
Multiple evidence points support the cause.
What you are seeing
Symptoms and likely causes
Typical signs
- Damp streak on the wall under the balcony after rain
- Water sitting at the sliding-door track
- Rust or gaps at railing post bases
- A neighbour on the floor below reporting a ceiling patch under your balcony
Causes we actually check
- Failed waterproofing at the door threshold
- Open joints at railing post penetrations
- Blocked balcony outlet, so the slab ponds against the door
- A previous acrylic coat that did not detail the posts
How Gracia diagnoses
Evidence before treatment
Visual of threshold, outlets and posts; moisture on the wall below. Thermal on the ceiling under the balcony when the stain is offset. Treatment is quoted on the balcony system — later civil cuts at the railing are excluded unless re-detailed.
Miyapur, Kukatpally and Gachibowli apartments: the first-floor balcony marks the elevation. Our Miyapur case is this — acrylic system, threshold detailing, outlets cleared, hose test after curing.
Probable
Evidence indicates the cause; further verification may still be required.
Possible
One or more clues exist, but the evidence is not enough for a firm conclusion.
Excluded
Inspected, and no supporting evidence found in the inspected area.

About this problem
Same family of systems, different details. Balconies fail at the door track and railing posts more than in the field of the slab. The quotation names those details.
