Greenish damp patches on walls or ceilings inside a room can occur due to various reasons, including:-
1. Water seepage or leakage:-
Through roofs, walls, or pipes, allowing moisture to enter and create an ideal environment for mold and mildew growth, appearing as greenish patches.
2. High humidity:-
Excessive moisture in the air, often due to poor ventilation, leading to condensation and dampness.
3. Leaking windows or doors:-
Allowing rainwater or outside moisture to enter the room.
4. Rising damp:-
Groundwater rises through the walls, carrying salts and minerals that can cause greenish discoloration.
5. Poor waterproofing:-
Inadequate or damaged waterproofing measures, such as faulty flashing or inadequate sealants.
6. Plumbing issues:-
Leaks from pipes or fixtures, causing water to seep into walls or ceilings.
7. Flooding:-
Previous water damage or flooding events that weren’t properly addressed.
These greenish patches can be a sign of a larger issue, and it’s essential to investigate and address the underlying cause to prevent further damage and potential health concerns.
