How do I prevent mould in my Nairobi home?

Mould is common in Nairobi homes during the long rains (March–May) and short rains (October–December). Left untreated it damages surfaces and causes respiratory problems, allergies, and skin irritation.

Why Mould Grows in Nairobi Homes

• High humidity during both rainy seasons
• Poor ventilation in bathrooms, kitchens, and wardrobes
• Leaking pipes or roofs allowing water ingress
• Cold walls in elevated areas (Ngong Hills, Runda) causing condensation

Prevention Strategies

• Ventilate daily – Open windows every morning; run bathroom fans during and 15 minutes after showering
• Fix leaks immediately – Roof or plumbing leaks must be repaired within days
• Use dehumidifiers – In rooms prone to dampness; keep humidity below 50%
• Dry laundry outside – One load adds 2–3 litres of moisture to indoor air if dried inside
• Seal grout and tiles annually – Waterproof barrier prevents mould in grout lines

Professional Mould Remediation

Established mould requires professional treatment — DIY bleach kills surface mould but not spores embedded in porous materials. Bestcare’s remediation uses HEPA vacuuming, anti-fungal treatment, and surface sealing for lasting results.
