Ceiling Leak Repair in Singapore
A leaking ceiling is almost always a symptom of a failed seal in the wet area above. Painting over the stain hides it for weeks; we trace the water back to its source so the repair actually lasts.
Signs you need this
- Brown or yellow water rings on the ceiling
- Paint peeling, blistering or flaking off
- Active dripping after someone showers upstairs
- Sagging or soft plasterboard
- Mould spreading across the ceiling corner
How we fix it properly
Because the cause sits above your ceiling, we coordinate access and use moisture and thermal tools to confirm exactly where the water enters the slab. This avoids the common mistake of treating the ceiling while the real leak continues overhead.
For HDB inter-floor seepage we follow the recommended approach of treating from the source unit where possible. Where ceiling-side sealing or PU grouting is the right call, we explain why and what to expect.
After the source is fixed we make good the ceiling — skim, prime and repaint — so you are left with a clean, dry finish rather than a patched stain.
Common causes we look for
- Failed bathroom or kitchen membrane in the unit above
- Leaking concealed pipe in the inter-floor slab
- Cracked floor screed letting water through
- Blocked or poorly sealed floor traps upstairs

Why does my ceiling leak come back after painting?
Paint only covers the stain. If the source above is not fixed, water keeps entering the slab and the stain returns. We treat the source first, then make good the ceiling.
The leak is from my upstairs neighbour — can you still help?
Yes. We are experienced with HDB and condo inter-floor seepage, including coordinating access and documenting the cause for discussions with neighbours, the MCST or Town Council.
Is PU grouting enough to stop a ceiling leak?
Sometimes. PU grouting seals cracks in the slab and is effective for certain seepage paths, but if the membrane above has failed, that is the real fix. We advise honestly on which your situation needs.
