Why Coastal Properties Face Extra Challenges
- Higher humidity - Sea evaporation increases ambient moisture
- Salt deposits - Attract moisture and damage protective coatings
- Temperature fluctuations - Sea breezes cause condensation
- Accelerated weathering - Seals and caulking degrade faster
- Metal corrosion - Including window frames and AC units
Special Precautions for Coastal Homes
- Use marine-grade sealants around all openings
- Install high-capacity dehumidifiers in sea-facing rooms
- Rinse exterior surfaces monthly to remove salt buildup
- Service AC systems quarterly (salt accelerates wear)
- Apply anti-corrosive treatments to metal fixtures
- Choose mould-resistant furnishings and fabrics
Leveraging Sea Breezes
While coastal location increases mould risk, sea breezes can help if used strategically. Open windows during dry, breezy periods to flush out humid indoor air. Close up during rain and high-humidity conditions. Use cross-ventilation to maximize the drying effect of sea breezes.
Frequently Asked Questions
Does salt air increase mould growth?
Indirectly, yes. Salt in the air is hygroscopic - it attracts and holds moisture. This can increase surface humidity on exposed materials, creating conditions favourable for mould. Salt also damages protective coatings, allowing moisture into building materials more easily.
Are coastal condos more prone to mould than inland properties?
Yes, coastal properties face: higher ambient humidity from sea evaporation, salt deposits that attract moisture, more intense sun/rain cycles, and often larger windows that increase condensation. However, good sea breezes can help if used strategically for ventilation.
How often should coastal properties be inspected for mould?
Quarterly inspections are recommended for coastal properties, compared to biannual for inland homes. Pay special attention during monsoon transitions. Check window seals and external walls more frequently as salt accelerates their deterioration.
What special maintenance do coastal homes need for mould prevention?
Coastal properties need: more frequent exterior cleaning to remove salt deposits, marine-grade sealants around windows and doors, dehumidifiers especially in sea-facing rooms, regular AC maintenance (salt accelerates corrosion), and anti-corrosive treatments on metal fixtures.
