Stop condensation from ruining your home

Ah, winterfall: that cold-yet-humid time of year that’s perfect for snow outside, and window condensation inside.

A problem in many homes (especially older builds), this type of moisture build-up can lead to mold, woodrot, and can cause other issues within the home as well.

To prevent condensation, you have to control the humidity and moisture levels in the house, manage the temperature and air flow inside, and keep cold air from getting into your home.


Using exhaust fans and vents throughout the house. Especially in dank places like the bathroom and with certain appliances that produce moisture.

Taking your plants outside. Indoor plants produce moisture which can exacerbate condensation issues. Place them outside whenever possible, or relegate them to a sunroom.

Turning off your humidifier. They’re designed to add more moisture to the air in your house, so if you’re experiencing moisture problems, turn off all the humidifiers in your house, including ones that are attached to the furnace.


Installing weather stripping to prevent cold air from blowing in from outside and cooling walls and windows.

Sealing cracks around windows and doors with caulking to prevent cold air from leaking into your home.


Opening the drapes. On sunnier days, open drapes and curtains to allow air to circulate; The warmth and light from the sun can also help dry out excess moisture

Using fans to move air around. Stand-up, oscillating, and ceiling fans are all great for circulating the air in your home. In winter, fans should rotate in a clockwise direction to help circulate heated air more efficiently.

And while it’s an expensive option, you could consider replacing older singlepane windows with storm windows that have double or triple glazing to improve the energy efficiency of your home, and reduce heating and electric bills.
