Quick Answer
NeighbourCare fixes mould caused by a neighbour's aircon on a shared HDB wall. Part 1 uses thermal imaging, moisture readings and data logging to confirm inter-flat condensation and produces a Condensation Risk Report suitable for HDB or Community Mediation Centre submission. Part 2 treats your side of the wall with a thermal insulating primer and anti-condensation topcoat that lowers surface dew-point vulnerability by 4–6°C, so it works without your neighbour's cooperation.

The problem
In HDB blocks, a neighbour running aircon hard against a shared party wall chills the concrete on your side. Warm, humid air inside your flat condenses on that cold surface and mould follows — usually on the shared wall, often near a corner or directly behind their aircon unit. It gets worse when they run the aircon and improves when they are away.
What we do
- Part 1 — Detection & assessment: thermal imaging, surface and ambient moisture profiling, and data logging to distinguish condensation from seepage or rising damp. You receive a professional Condensation Risk Report.
- Part 2 — Treatment & protection: thermal insulating primer plus anti-condensation topcoat on your wall, with a conditional warranty tied to keeping indoor humidity below 65% RH.
- Documentation: the report is formatted for HDB and Community Mediation Centre submissions when a dispute arises.
Frequently asked questions
How do I know if my mould is caused by neighbour's AC or something else?
Inter-flat condensation typically appears on shared walls (party walls) with your neighbour, often near the corner or areas where your neighbour's AC is located on the other side. It worsens when your neighbour runs AC heavily and improves when they're away. Our Part 1 Assessment uses thermal imaging and data logging to definitively confirm the cause—ruling out seepage, leaks, or rising damp.
Does my neighbour need to cooperate for this service to work?
No, that's the key advantage of our Part 2 Treatment. The anti-condensation coating treats YOUR wall to prevent condensation formation regardless of your neighbour's AC habits. While we provide behavioural guides for both parties, the technical solution doesn't require ongoing neighbour cooperation.
What if I only need the assessment to show HDB or for CMC mediation?
Part 1 Detection & Assessment can be booked as a standalone service. You'll receive a professional Condensation Risk Report with thermal images, moisture readings, and data logging results—all suitable for submission to HDB or the Community Mediation Centre.
How long does the anti-condensation treatment last?
Our thermal insulating primer and anti-condensation topcoat system provides long-lasting protection with a conditional warranty. The treatment reduces surface dew point vulnerability by 4-6°C, preventing condensation formation under typical Singapore conditions. The warranty is conditional on maintaining indoor humidity below 65% RH.
Can I claim this against home insurance?
Most standard home insurance policies don't cover gradual condensation damage. However, if you're pursuing a neighbour dispute through mediation, our assessment report provides professional documentation of the cause and damage. Some comprehensive policies may provide partial coverage for mould remediation—check your specific policy terms.
What is the difference between condensation and seepage?
Condensation forms when warm, humid air contacts a cold surface—caused by temperature difference, not water infiltration. Seepage is actual water coming through the building structure from a leak or external source. They require completely different solutions. Our assessment uses thermal imaging and moisture profiling to accurately distinguish between them.
