Interior window condensation is one of the most annoying things to accompany the arrival of the heating season, obstructing the view to the outside and causing homeowners to constantly have to wipe down their windows. During the cold winter months, some homeowners will find that condensation is produced on the inside of windows. This problem can be extremely damaging not only to the affected windows, but to everything around it. If you’re plagued by winter window condensation, there are a few ways you can reduce or eliminate this annoying problem.

What is interior window condensation and why is it a problem?
Condensation happens when water vapor or moisture in the air is turned into liquid water. It happens after interior air that has been able to warm up and hold more moisture cools down and contrasts, reaching a saturation point where the excess moisture turns into liquid water.

Condensation happens on windows so regularly because the warm air circulating around your home makes contact with cold window panes, causing the air to quickly cool and reach its saturation point, releasing excess moisture as liquid on the surface of the window. Condensation regularly happens on window exteriors, especially during more humid summer months – that condensation is considered to be normal, whereas excess interior window condensation is not.

Condensation on window interiors can quickly become a major problem for homeowners, as it means that there may be excessive moisture in your home. This can eventually cause problems that include mold growth on and around the window, as well as visible rot and decay around the windows. The unchecked spread of mold, rot, and decay can cause damage to your home and to the health of those within it. If this is not remedied, it can cause irreparable damage to the windows and surrounding parts of the home, demanding costly repairs.

Monitor internal humidity levels and adjust accordingly
One of the first steps in eliminating window condensation is to monitor the humidity in your home with a hygrometer, a device that allows you to easily gauge internal humidity levels. Being able to determine how much humidity is in your home is key to deciding how to tackle the problem. If your home contains higher than normal humidity levels, purchasing a dehumidifier is recommended, as it will regulate internal humidity levels which has been shown to reduce internal condensation on windows. If you have a modern thermostat in your home, it may come with a built-in humidity meter.

Lower the temperature
While it may seem counterintuitive to lower the temperature during the winter months, doing so will go a long way to reducing buildup of condensation on windows. Warm air in your home contains more moisture, so lower the thermostat by even a degree or two will greatly reduce its ability to carry excess moisture. If you can spare a couple degrees, lower the temperature inside will reduce some of the humidity and condensation.

Improve ventilation and seal leaks
Improving the ventilation is another major way to reduce condensation on windows. To do this, homeowners can run fans while using appliances like ovens or dryers, or even during showers. Unblocking covered or blocked vents is another way to improve the ventilation in your home – this can be done by moving furniture away from vents and cleaning ventilation covers to ensure that air can easily move around your entire house. Vents should be cleaned if you notice large amounts of dust, as dust can impair ventilation and reduce airflow.

Changing filters and monitoring filter health is another recommendation to improve air quality and ventilation. It’s also recommended that you seal any leaky ducts that may exist in your home, as these leaks are responsible for a huge amount of air loss from your home. Fixing these leaks can improve the flow of air and improve air circulation, reducing humidity and condensation. With the right strategy, your windows can be free of condensation this winter. The winter season provides the perfect opportunity for homeowners to install new windows in your Muskoka home or cottage. Not only will upgrading windows reduce interior condensation, they also work to prevent energy loss, keeping you more comfortable and increasing your home’s overall energy efficiency.
