When water leaks through the ceiling from the flat above, the repair is shared jointly by the upper- and lower-floor flat owners, because the slab between them serves both. Under HDB’s Goodwill Repair Assistance (GRA) scheme, HDB pays 50% of the repair cost for wear-and-tear leaks, and the two owners split the remaining 50% equally, so each pays a quarter. If the leak was caused by renovation in the upper flat, its owner pays the full cost. Seepage through external walls or from the roof into a top-floor flat is different: those are common property, and the Town Council is responsible.
A drip from the ceiling is stressful, and it often lands just as you have finished painting. The good news is that the rules are settled. Here is who does what.
Quick facts
- Inter-floor ceiling leaks: joint responsibility of the upper- and lower-floor owners.
- Goodwill Repair Assistance: HDB co-pays 50%; the owners share the other 50% equally.
- Renovation-caused leaks: the upper-floor owner bears the full cost.
- External walls: common property managed by the Town Council.
- Roof leaks into top-floor flats: the Town Council is responsible for the roof.
- Flats with ceiling leaks reported in 2025 averaged about 40 years old.
Who pays for which leak?
| Type of leak | Who is responsible | Help available |
|---|---|---|
| Ceiling leak from the flat above (wear and tear) | Upper- and lower-floor owners jointly | HDB pays 50% under GRA; owners split 50% |
| Ceiling leak caused by upper-floor renovation | Upper-floor owner, in full | None from the shared scheme |
| Seepage through an external wall | Town Council | HDB gives technical advice on complex cases |
| Roof leak into a top-floor flat | Town Council | HDB advises the Town Council |
| Defects in a newly completed flat | HDB, within the defects liability period | Report through HDB’s defect channels |
A worked example: splitting the bill
Suppose the contractor quotes $2,000 to fix a wear-and-tear leak in the bathroom slab between two flats, and the case qualifies for Goodwill Repair Assistance.
- HDB pays 50%: $1,000.
- Upper-floor owner pays 25%: $500.
- Lower-floor owner pays 25%: $500.
If the leak traced back to the upper flat’s recent renovation, the upper-floor owner would pay the full $2,000. The figure here is an illustration, not a typical price; quotes vary with the cause and the method.
What to do when you spot a leak
- Record it. Take dated photos of the stain, drip and any damage.
- Work out the source. A ceiling stain usually points to the flat above; a damp external wall or top-floor ceiling points to the Town Council.
- Talk to your neighbour. Repairs are usually done from the upper flat, so you need their cooperation and access.
- Contact HDB for inter-floor leaks, or your Town Council for external walls and the roof.
- Ask about Goodwill Repair Assistance before work starts, so the cost share is agreed in advance.
For serious leaks, MND said in September 2025 that HDB will expedite repairs, subject to the upper-floor owner’s availability, and may do temporary repairs in the lower flat. Residents who need help with their share can be referred to grassroots organisations and Community Development Councils.
The WahLiao Verdict
Knock on your neighbour’s door early and kindly; a leak fixed together is cheaper and calmer than one fought over. Report inter-floor leaks to HDB and ask about the Goodwill Repair Assistance share before any contractor starts, and send external wall or roof problems straight to your Town Council. If you are renovating, waterproof properly, because a leak your works cause is yours to pay for in full.
Questions people ask
My upstairs neighbour won’t cooperate. What now?
Contact HDB, which helps with investigation and advice on inter-floor leaks. For a stubborn dispute, community mediation or the Community Disputes Resolution Tribunal may help.
Does HDB fire insurance cover leak damage?
HDB fire insurance is designed for fire damage to the flat’s structure. Check your home contents or home insurance policy for water damage cover.
Who fixes damp patches on my outside wall?
External walls are common property, so your Town Council is responsible. Report it to them directly.
I live on the top floor and the ceiling leaks. Who pays?
If the water comes through the roof, the Town Council is responsible for the roof. Report it to them.
