Condensation builds when warm moist air hits a cold surface. Reduce moisture and improve airflow and you’ll see fast results.
Quick Fixes
- Open trickle vents or crack the window for 5–10 minutes.
- Run a small dehumidifier on a humidity target (e.g., 50%).
- Use extractor fans during showers and cooking.
- Dry clothes in a single room with the door closed + dehumidifier.
Night Routine For Bedrooms
- Run dehumidifier on low before sleep.
- Keep doors slightly open for airflow if possible.
- Wipe heavy condensation in the morning to prevent mould.
Longer-Term Improvements
- Draught seals, thermal curtains, window film.
- Check for hidden damp sources (leaks, blocked vents).
