Tips for flats and housing societies
- Seepage on your ceiling usually comes from the flat above. The repair is generally done in that flat — involve the owner above and your maintenance office early.
- Seepage from external walls, the terrace or common pipes is usually the society’s responsibility to fix.
- Fix seepage before the monsoon and before painting, not after.
- Keep photos and dates of the damage — they help when discussing the issue with neighbours or the RWA.
How to prepare
- Take photos of the affected areas and note when you first noticed them.
- Find out whether the flat above has had recent bathroom work.
Frequently asked questions
Who pays for seepage coming from the flat above?
Generally the owner of the flat where the leak originates is responsible for fixing it. Your society’s bye-laws and maintenance office can help resolve disputes.
How much does bathroom waterproofing cost?
Small repairs like re-grouting cost ₹3,000–₹15,000; complete floor waterproofing with re-tiling usually costs ₹25,000 or more.
Can seepage be fixed without breaking tiles?
Often yes, using epoxy grouting or chemical injection. Severe cases need re-tiling with a proper waterproof layer.
How long after repair can I paint?
Usually a few weeks, once the wall has dried completely. Painting too early causes peeling.
