In recent years, residents of several Housing and Development Board (HDB) flats in Singapore, particularly in Sengkang and Punggol, have raised concerns about persistent mold growth in their homes. Among the affected estates are Anchorvale Parkview and Matilda Court, where homeowners have reported recurring mold problems despite repeated cleaning efforts. The issue has gained enough attention that HDB announced that it would commission an independent study to investigate the mold problems in these flats. This move came after residents and Members of Parliament (MPs) highlighted the health risks and structural concerns associated with persistent mold growth. 

This article examines the mold situation in Anchorvale Parkview and Matilda Court, exploring possible causes, health implications, resident experiences, and official responses.

According to a recently updated report (originally published in February 2023) by The Straits Times, residents in some Sengkang and Punggol flats have been struggling with mold growth on walls, ceilings, and furniture. The problem appears to be more prevalent in newer flats, with Anchorvale Parkview and Matilda Court, both of which were completed in 2017, being among the affected estates. Mold thrives in damp, poorly ventilated environments, and Singapore’s tropical climate—with high humidity and frequent rain—creates ideal conditions for its growth. However, residents argue that the issue in these estates goes beyond typical humidity-related mold, suggesting possible construction or material-related factors.

1. Recurring Mold Despite Cleaning

Many residents have reported that mold reappears within days or weeks of cleaning. Some have resorted to frequent scrubbing, using dehumidifiers, and even repainting walls with anti-mold coatings—only for the problem to persist.

2. Health Concerns

Exposure to mold can cause respiratory issues, allergies, and skin irritation, particularly in children, the elderly, and those with weakened immune systems. Some residents have reported increased asthma attacks and persistent coughs, leading to concerns about long-term health effects.

3. Structural and Aesthetic Damage

Beyond health risks, mold causes stains, peeling paint, and deterioration of walls and furniture. Some residents worry about the long-term structural integrity of their homes if the issue remains unresolved.

Potential Cause	Investigation Findings
1. Construction Materials and Design Flaws	Some suspect that certain building materials used in these estates may retain moisture, promoting mold growth. Others point to possible insufficient waterproofing or ventilation design flaws in newer HDB flats.
2. Delayed Defect Rectifications	A few residents claim that initial defects (such as leaks or cracks) were not adequately addressed during the Defects Liability Period, allowing moisture to seep into walls over time.
3. External Environmental Factors	Proximity to water bodies (such as the nearby Punggol Waterway) and higher-than-average rainfall in recent years may have contributed to increased dampness in these areas. In fact, reported cases of mold formation were known to increase during the rainy season.

Following persistent complaints, the HDB announced that it would commission an independent study to investigate the mold issues in Sengkang and Punggol flats, including Anchorvale Parkview and Matilda Court.

Key points from the HDB’s statement:

The study will assess whether there are systemic issues contributing to mold growth in these estates.

Findings will help determine if construction methods, materials, or environmental factors need adjustments.

HDB will work with affected residents to provide temporary solutions, such as inspections and remedial measures, while the study is ongoing.

While awaiting the study’s results, residents can take steps to minimize the impact of mold growth:

Improve ventilation. Use exhaust fans, open windows regularly, and consider using dehumidifiers.

Do regular cleaning. Use mold-killing solutions (e.g., vinegar, bleach, or commercial anti-mold sprays).

Check for leaks. Report any plumbing or ceiling leaks to HDB for repair.

Use mold-resistant paint. If repainting, opt for anti-microbial or mold-resistant coatings.

The mold issues in Anchorvale Parkview and Matilda Court highlight a growing concern among HDB residents in newer estates. While Singapore’s climate naturally contributes to mold growth, the persistence and severity of the problem in these areas suggest deeper underlying factors. HDB’s decision to commission an independent study is a step in the right direction, but affected residents hope for swift and effective solutions—whether through improved construction standards, better ventilation designs, or enhanced defect rectification processes. For now, residents must remain vigilant in managing mold growth while awaiting official findings and long-term fixes.
