Common Rainy Season Home Maintenance Problems and Solutions in Singapore
Singapore's monsoon seasons from November to January and June to September bring heavy rain and high humidity, leading to leaks, mould, clogged gutters, and flooding in HDB flats, condos, and landed properties[1][5]. Homeowners can prevent most issues with simple checks like cleaning gutters, sealing cracks, and ensuring ventilation, avoiding costly repairs that average S$500-S$2,000 for water damage[4]. This cluster article provides actionable fixes, building on our pillar guide to Complete Singapore Home Maintenance Guide.
1. Roof Leaks and Waterproofing Failures
Roof leaks are the top rainy season problem, caused by cracked tiles, poor seams, or degraded materials during Singapore's intense downpours[1][4]. In HDB flats, check common roof areas accessible via town council; condos follow MCST rules for shared roofs. Water seeps through ridges or equipment mounts, leading to interior damage.
Actionable Solutions:
- Inspect roofs before monsoons: Look for loose tiles, cracks, or rust. Use binoculars for safety[1].
- Apply silicone sealant temporarily on small leaks, but hire BCA-licensed waterproofers for PU grouting or membrane coating (S$1,200-S$3,000 for 1,000 sq ft)[4].
- Secure tiles with screws and eaves guards to prevent wind uplift[4].
Book verified roof experts via Homejourney for upfront quotes and service guarantees, ensuring HDB-compliant work.
2. Clogged Gutters and Downpipes
Leaves, twigs, and debris block gutters, causing overflow that damages walls and foundations, especially in landed homes or high-floor HDB units[1][3][5]. PUB notes poor drainage contributes to 30% of flash floods in urban areas.
Step-by-Step Fix:
- Wear gloves and use a ladder to remove debris; flush with hose[3].
- Install gutter guards (S$10-S$20 per meter) to reduce cleaning frequency[3].
- Check monthly during rains; contact town council for common drains[1].
For professional cleaning, Homejourney connects you to vetted providers with transparent pricing (S$150-S$400 per session), preventing S$1,000+ flood repairs.
3. Mould Growth and High Humidity
Humidity above 80% in bathrooms, kitchens, and storage fosters mould, risking health issues like allergies per NEA guidelines[2]. Basements in landed properties and poorly ventilated HDB corners are hotspots[2].
Prevention Tips:
- Monitor with hygrometer; keep below 60% using dehumidifiers (S$200-S$500)[2][7].
- Improve ventilation: Run exhaust fans 30 minutes post-shower; open windows during dry spells[2].
- Clean with mould-resistant products weekly; repair leaks immediately[2].

4. Wall and Floor Seepage
Cracks in walls or floors allow water ingress, causing peeling paint, rusting rebar, or electrical hazards—critical in older HDB blocks[4]. Balcony drains often clog, worsening seepage.
Solutions Framework:
- Seal gaps around doors/windows with weatherstripping (S$50 kit from hardware stores).
- For severe cases, use epoxy injection or wall waterproofing (S$800-S$2,500)[4].
- Check electrical points; elevate plugs 1m above floor per BCA safety standards.

5. External Drainage and Flooding Risks
Blocked walkways and drains cause localized flooding, common in low-lying estates like Bedok or Jurong[1][5]. Trees near homes risk branch falls during storms[4].
Quick Checks:
- Clear litter from drains weekly; report to town council if clogged[1].
- Trim overhanging branches; install sandbags for flood-prone areas (S$20 per bag)[5].
- Elevate appliances and use waterproof covers.
