Why is there condensation on my windows?
When air cools down, it reaches its dew point (the temperature at which condensation forms). The higher the humidity level of air, the higher the dew point. The problem is not bad windows — it’s good science. Condensation on your windows means the humidity levels in your house are too high. If you’re getting condensation on your windows, you’re likely getting condensation within the exterior wall cavities of your house!
What do I do now?
Reduce moisture sources within your house:
- Don’t store firewood in the home.
- Repair foundation leakage problems.
- Turn down or turn off your humidifier.
- Cover any exposed earth floor in a basement or crawl space.
- Cover sump pits.
- Don’t hang laundry to dry inside your home.
- Limit the use of vaporizers or steam generators.
- Dehumidify your basement with dehumidifier.
Ventilate your home:
- Vent your clothes dryer to the outside.
- Use exhaust fans when showering or cooking.
