My HDB toilet ceiling is leaking from above — who pays?
For HDB flats, upper and lower units split costs 50/50. HDB's Goodwill Repair Assistance (GRA) scheme covers most of it — each owner is capped at around $350 per toilet. If you're on the top floor, the Town Council pays.
How much does no-hack toilet waterproofing cost?
No-hack flood infusion or chemical grouting costs $600–$1,500 per toilet. PU injection starts at $600 for one toilet or $950 for both (e.g. Sin Jit Seng, XRY, DryProof pricing). This is for HDB flats across Tampines, Jurong, Woodlands, and all SG areas.
Should I use flood infusion or full hacking?
Flood infusion is faster, cleaner, and cheaper ($600–$1,500) but works best for minor to moderate leaks. Full hack, membrane replacement, and retiling ($1,500–$4,000) is the permanent solution for severe slab or drainage failure.
My upstairs condo neighbour refuses to fix their toilet leak — what can I do?
Under the BMSMA, the upper unit is presumed liable. Escalate via your MCST or managing agent, then file with the Strata Titles Board (STB) with a $500 filing fee. You can claim up to $20,000 via the Small Claims Tribunal. Mediation takes 4–8 weeks.
Is there emergency waterproofing that can come today?
Yes. Several Singapore contractors offer same-day inspection. WhatsApp response is typically within minutes, with on-site visit within 2–4 hours for urgent cases like active leaks or mold growth — from Bedok to Yishun, all areas covered.
What's the difference between PU injection and traditional waterproofing?
PU injection targets specific cracks from below — no hacking, $300–$1,000, completed in 1 day. Traditional waterproofing involves hacking the floor, applying a new PU/cementitious membrane, ponding test, and retiling — $1,500–$4,000. PU is faster but may not address widespread membrane failure.
My BTO flat is leaking — is the developer responsible?
Yes — within the 12-month Defects Liability Period (DLP), the developer covers defective waterproofing. Document defects and submit before DLP expires. Post-DLP wear and tear falls on you or your neighbour.
