What to prepare before HDB looks at a ceiling leak

Last updated 31 October 2026. Prices below are bands already printed on HomeySG. This page is not legal advice.

A brown ring on an HDB ceiling is not yet a bill and not yet anyone’s fault. It is a mark you should date. HDB’s letter to the press on the Goodwill Repair Assistance scheme says flat owners maintain the interior, and that a leak in the floor slab between flats is a joint responsibility of the upper and lower owners. The practical sentence is the one people skip: the lower owner should approach the upper owner early, so the leak is fixed while it is small. Waiting until the paint is on the floor, then demanding a full toilet upgrade upstairs, is how a repair becomes a feud.

The same letter describes the scheme HDB offers for leaks from wear and tear over time. Repair works are done in the affected areas of both flats. HDB pays 50 percent of the repair cost. The remaining 50 percent is shared equally by the upper and lower owners. Once both agree, HDB arranges the contractor. The work can include a new waterproof membrane on the upper floor and skim coat, sealer and paint on the lower ceiling. It does not include your lights, cabinets, shower screen or other fittings you installed. Claims for those are a private matter between owners. That is HDB’s wording, not a ruling on your flat. The short page on who pays is still worth reading. This page is the folder you bring to the inspection.

A second letter, in May 2021, shows the edge of the scheme. A resident’s kitchen ceiling was leaking from a water-supply pipe inside her own flat, which she had covered with trunking. HDB inspected the same day and said the goodwill scheme did not apply. She had hoped wear and tear of an original pipe would be enough. It was not, because the scheme is aimed at the slab between flats, and at breaking a deadlock between neighbours. One flat, one pipe, no neighbour: engage a plumber. Read that letter before you insist on a scheme your photos may not support. Our leak-detection page is how you find out whether the meter is moving.

What the officer is trying to learn is the path. Rain only, with the bathroom unused, may be the external wall or, on the top floor, the block roof. Both are town-council common property. HDB’s ceiling-leak page says so. A stain that grows when the upper bathroom is used, with a still water meter, is the pattern of a membrane or a waste fitting. A meter that moves with every tap shut is a supply leak, and the second letter is the warning that a supply leak may not be the scheme. You help the inspection by not mixing the tests. Do not shower, run the aircon and open the windows in a storm on the same afternoon and then ask which one did it.

Keep the finishes on until someone who can authorise the hack has looked. A private contractor who lifts the upper toilet tiles “to be helpful” can destroy the evidence, can breach the 3-year rule if the block is new, and can take the repair outside the scheme the officer was about to offer. HardwareZone threads describe residents being told that a chemical or flood-injection method was not the goodwill path, and that the subsidised path was a conventional hack, membrane and re-tile. Those are forum accounts, not the letter. Ask the officer which methods the scheme will pay for today. Do not let us sell you a method that knocks you out of a subsidy you wanted.

The 3-year rule and the 1-year defects period are different clocks and both matter at an inspection. Toilet finishes must not be replaced for 3 years from the block’s completion. A new flat’s defects liability period is 1 year from key collection. If you are inside the defects year, report the leak as a defect before you agree a private cost share. If the upper flat was just renovated, say so. A membrane damaged by a hack is not the same story as wear and tear, and the letter frames the scheme around wear and tear. Whether a particular renovation throws the case out is the officer’s call. It is not ours.

Residents on HardwareZone discuss a cap, sometimes described as a few hundred dollars per toilet, and a defects period on the council’s or HDB’s contractor. The two HDB letters cited here do not print a dollar cap. We will not print one either. When the officer offers the scheme, ask what is included, what each household will be billed, and what happens if the stain returns. Write the answers down. The who-pays page on this site is the short map. If a number on an old forum post disagrees with the officer, believe the officer and the current letter, not the thread and not us.

Homey Furnishing Pte. Ltd. (ACRA UEN 202018148K), 27 Mandai Estate, #06-10 Innovation Place, Singapore 729931, invoices permit-exempt leak checks, regrouting, silicone, and making-good after the water has stopped. V On Construction Pte. Ltd. (ACRA UEN 201611708H), on the HDB Directory of Renovation Contractors, invoices an HDB renovation permit when bathroom finishes are hacked or a new membrane is laid under new tiles. A concealed or new water-supply pipe is a PUB licensed plumber. Homey Furnishing is not that plumber and does not publish a waterproofing warranty term.

Curtains, blinds and roller shades are not part of this booking. Fabric window treatments are a different product, and these pages do not quote them.

Build a thin folder. Officers have a lot of flats. A clear folder is how yours gets a clear answer.

1. Date the first photo of the stain. Tell the upper owner. Keep the message.
2. Make a three-column note for a week: rain, showers upstairs or yours, and anything else (flush, aircon, heater).
3. Photograph the meter once with everything off, and again after 15 minutes, so a supply leak is not argued from memory.
4. Do not hack, do not paint, and do not silicone the lower ceiling shut.
5. At the inspection, ask whether it is common property, a supply pipe, or a slab leak that can be the goodwill scheme. Ask what each party pays. Leave with the answer in writing if they will give it.

This page is the HDB process. A condo does not have this scheme. Use the MCST page for strata. A landed house has no upstairs HDB officer.

You do not have to diagnose the membrane. You do have to be precise. “It drips when they shower, and it did not drip during Tuesday’s storm” is useful. “The upstairs people are inconsiderate” is not. Offer access. A locked flat during the appointment is how a case sits for weeks. If water is hitting a light, say that first and isolate the circuit. Safety is not a talking point to save for the end.

Ask whether both toilets upstairs were checked. Forum accounts describe a second bathroom being the real source after the first was repaired. That is a reason to test both wet rooms, not a reason to accuse the officer. If you are the upper owner, do not refuse access and do not start a renovation that lifts the tiles the same week. Cooperation is what the letter says unlocks the contractor.

If the scheme is offered and you both accept, the membrane and the ceiling paint are their scope, on their specification. Extra tiles so the upper bathroom matches a new design are, on the letter, not part of the fittings they cover. Budget that yourself or keep their tiles. If the scheme is refused because the meter moved, book the leak-detection visit at S$140 to S$220 and a licensed plumber if the pipe is concealed. If it is refused because the wall is external, go back to the town council with the officer’s note.

Paint the ceiling when it has stayed dry. The hairline and water-stain band is S$150 to S$400. Painting the week of the leak seals the water in and the stain returns, which looks like a failed repair and restarts the argument. Window-frame drips that were blamed on the flat above belong on the window sealant page once the ceiling test says the slab is dry.

Use this after the inspection, or to prepare for it. It is not a decision you should enforce on a neighbour.

Questions for the officer, and for any contractor who wants to start before the officer comes.

1. Is this common property, an in-flat pipe, or the slab between the flats?
2. If it is the scheme, what percentage is HDB paying, and what is each owner billed? Is there a cap on this case?
3. Which rooms are included, and are my fittings included?
4. Will a no-hack injection be accepted, or only a hack and membrane?
5. The block completion date and the key-collection date: which clock are we in?
6. If I paint now, does that affect the inspection?

Start with the neighbour and HDB’s ceiling-leak page. If the conversation has already failed, the officer is the escalation, not a lawyer you found first and not a hack you arrange at the weekend. This page is not legal advice and not a prediction of what HDB will decide.

If concrete is falling or water is in the electrics, deal with that hazard the same day. Isolate power. Keep people out of a drop zone. SCDF at 995 if you cannot make it safe. Do not open a household shelter to “see where it comes from”.

How you're charged

A leak or waterproofing job that already has a sentence on HomeySG uses that sentence. Nothing in this table is a fuel surcharge, and the handyman hour is not added on top of a band unless the written scope says so. A membrane, a balcony, a planter, a roof, an epoxy-grout system, or a listening survey with no matching row is quote on inspection.

Who is allowed to do the work

HDB’s renovation pages split a coat of silicone from a hacked bathroom. Replacing toilet wall and floor finishes is not allowed for 3 years from the completion date of the block, because a membrane sits on the screed. After that, a replacement uses pre-packed waterproofing screed, a membrane upturned at least 150mm at walls, kerbs and pipes, a UPVC floor-trap grating with a long collar, and a water test. Fines for unauthorised work are already written on the permit guide as up to S$5,000. Homey Furnishing does not sign the permit invoice.

• Regrout, a silicone zone, hollow-tile injection and a stain repaint after the water has stopped stay on the published rows. They do not replace a membrane.
• Opening the bathroom floor or wall finishes is V On Construction when the flat is HDB and the work needs a permit.
• PUB’s leak leaflet says it is an offence under the Public Utilities Act to engage an unlicensed worker for plumbing work. A concealed or new supply pipe is a licensed plumber. An exposed trap is a different visit.
• External walls of an HDB block are common property. The town council on the S&CC bill is the first report, not a private injector.
• SCDF does not allow hacking of household-shelter walls, floor slabs or ceiling slabs to chase a pipe. The leak is found another way.
• A window-frame leak is the window sealant page. Exterior rivets and stays stay with a BCA approved window contractor.
• Curtains, blinds and roller shades are not quoted here.

Ways to keep the bill smaller

• Photograph the stain, the wet room, and the water meter before anyone hacks. A hack that destroys the evidence is a second problem.
• Run one test at a time. Shower, flush, aircon and rain on the same afternoon make a useless log.
• If the joint is only mouldy silicone, the published zone is S$80 to S$150. That is not a membrane.
• If the ceiling is already dry and the source is fixed, the hairline repaint is S$150 to S$400. Paint on a live leak is how the stain returns.
• One clear week of notes is the cheapest way to avoid paying the wrong trade. Do it before you agree a share.

Official pages, not a legal opinion

Read the letters. If HDB’s page has been updated since 31 October 2026, the page wins and this article is behind it. Nothing here is a legal opinion.

• HDB goodwill scheme letter. HDB pays half. The two owners share the other half. Fittings are excluded.
• HDB letter, scheme refused. An in-flat supply pipe was not the scheme.
• HDB ceiling-leak guide. Common property goes to the town council.
• New-flat defects. One year from key collection.
• 3-year finish rule. Do not replace toilet finishes inside that window.
• Parliament on seepage. External walls are the town council. 859 complex cases in 2024 is HDB’s figure for cases it assisted.
