Short answer: Probably, if the flat is new enough. HDB fixes defects reported within the one-year defects liability period. After that, new flats carry a 5-year warranty on ceiling leaks and external seepage and a 10-year warranty on spalling concrete. The ceiling-leak warranty ceases if floor tiles are changed or the waterproofing system is tampered with.
Seepwise writes these guides from HDB, MND and BCA sources and published Singapore price data; each claim links to where it comes from.
The three time windows
| Window | What is covered | Who fixes it |
|---|---|---|
| Defects liability period, 1 year | Defects reported during the period | HDB, at no cost to you |
| Warranty, 5 years | Ceiling leaks and external seepage | HDB |
| Warranty, 10 years | Spalling concrete | HDB |
Sources: HDB; the DLP start date is set in your agreement and guides describe it differently (Dollars and Sense).
What ends the ceiling-leak warranty
HDB states the 5-year ceiling-leak warranty ceases if floor tiles are changed or the waterproofing system is tampered with (HDB). Renovation guides add that wet-area floor tiles in new flats should not be changed in the first three years (Hometrust). Defects caused by your own renovation or poor maintenance are not covered (Qanvast).
What to do if your BTO ceiling leaks
- Photograph the stain with the date and note when it grows.
- Check the unit above: if it is also new, the leak is likely within the warranty.
- Report it to HDB before any contractor touches the tiles.
- Keep copies of everything you send and receive.
After the warranty
Once the warranty ends, ceiling leaks become a shared cost between the upper and lower owners, with HDB’s Goodwill Repair Assistance having co-paid 50% (MND). See who pays for an HDB ceiling leak.
Bottom line
New flat, new leak: report to HDB first and leave the tiles alone. Outside the windows, request an inspection to find the source and the cheapest route to fixing it.

More questions
When does the defects liability period start?
It runs for 12 months; guides describe it starting from key collection or shortly after the Temporary Occupation Permit, so check your agreement for the exact date.
Who fixes leaks after the warranty ends?
The owner, with HDB's Goodwill Repair Assistance available for wear-and-tear ceiling leaks and spalling.
Should I renovate the toilet before reporting the leak?
No. Changing tiles or the waterproofing can end the warranty that would cover the repair.
