Why do my windows keep fogging up in the winter?
Interior window condensation or “fogging” occurs when excessive moisture builds up inside a home and that warm air meets a cold window – that’s when condensation or “fogging” occurs.
Many times, window condensation can be a sign of several issues:
- The humidity level in your home is too high
- Significant moisture has been generated in your home over a short period of time due to events such as cooking, multiple showers, etc. If the condensation dissipates within a few hours, this is nothing to be concerned about, however, if it remains, it could be a sign of a more significant issue
- Insufficient air flow and circulation throughout your home
- Windows or doors could have an issue and are not sealing tightly
Here’s a few things you can do to eliminate window condensation:
- Turn down the humidity in your home by 5-10% and allow 24 hours for your home to adjust
- Turn on your furnace fan to help circulate the air more efficiently. A new furnace with the proper thermostat will give you the ability to adjust the speed of your circulation fan – which is very convenient.
- Use bathroom and kitchen fans to help exhaust humid interior air
- Check the humidifier on your furnace to see if it’s operating properly or call in an Energy Clean certified technician to service it and ensure its operating correctly.
- Open your blinds or drapes to allow warmer air to circulate away from the windows.
- Buy and use a portable dehumidifier or install a central dehumidifier.
- Open your windows for a few moments, if the outside temperatures are not prohibitive.
- Check and possibly replace the weather stripping around your windows and doors
- Use storm windows and doors if you don’t already have them
- If the problem is ongoing, consider purchasing an air exchanger (HRV, ERV) for your furnace by speaking with an Energy Clean Home Services Comfort Specialist
- Move your plants away from windows – plants generate moisture and therefore aid in the humidity process which can fog your windows
