Why Bishan sees this kind of mould
Bishan's housing stock is dominated by well-maintained 1980s–1990s HDBs and a strong cluster of premium condominiums (Sky Habitat, Bishan 8). Owners typically expect discreet, no-mess remediation — and we see a higher share of preventive repaints with Zinsser/Gush rather than emergency call-outs.

How this is calculated: live layer 60% — moisture & mould risk 30, outdoor air 20, thermal 10, from NEA humidity, temperature, rainfall, PSI and PM2.5 by reporting zone. Structural layer 40% — housing age and waterproofing 15, exposure 10, density and shading 8, our field record 7. Same 0–100 scale and bands (Excellent 85+, Good 70+, Fair 55+, Poor 40+, Critical under 40) as the Home Wellness Index. UV and noise are national context only and never scored.
