Everything You Need to Know about Window Condensation – Part 2: How Window Condensation Affects Your Home

There are other situations when condensation happens for a reason other than excessive indoor moisture. If the condensation forms between the panes of glass, for instance, it can only mean the seals on your double-pane windows are failing or have already deteriorated. This makes it easy for outdoor air to enter your home, leaving moisture to get trapped between the panes until it condenses.

How Window Condensation Affects Your Home

Window Condensation and Your Home

What happens when the condensation forms in the center of the glass? Your windows probably have a gas leak–that is, the insulating gas filling the air space between the panes is escaping. When it has leaked out, the window won’t provide proper insulation, allowing for condensation. Both instances can greatly affect your home and quality of life. Here’s how:

    • Window condensation obscures the view If you’re lucky enough to own a home with a stunning view, you won’t get to enjoy it much when there’s fog on your windows. Condensation can block out your view, while filtering the amount of natural light that spills into your rooms. This results in hindered outdoor views and a dimmer home.
    • Window condensation can lead to significant energy loss. Because the seals on your windows have already failed and its gas fill has oxidized, cold air can make its way into your home while heated, regulated air escapes out. This compromises the thermal stability of your living spaces, pushing your HVAC system to work overtime to fill the gap, which leads to higher energy bills.
  • Window condensation can physically damage your units. The water accumulating on window glass will drip eventually. Aside from causing unsightly water stains to form on your windows, dripping water can pool, leaving your window frame vulnerable to permanent moisture damage, encouraging mold and rot.

To prevent these issues and maintain your home’s comfort and energy efficiency, you should take proactive measures that help reduce excessive indoor moisture. These include investing in replacement windows from a trusted contractor in your area that offer excellent ventilation.

In the last installment of this three-part blog series, we share tips on reducing the potential for window condensation in your home. Stay tuned!


"I would recommend RBA of Central Illinois for QUALITY windows and doors. Compared to our old cheap, thin vinyl windows, Andersen blows them away. You can easily tell by how well the sliding doors fit and close, and how heavy duty they are. We also cannot hear the wind rushing through the house in inclement weather anymore! And the black window frames we went with are amazing to look at. Aaron, Al, Darrell, and Cory all were professional and went all out to finish the job, given the weather they had to deal with. I would definitely recommend. They were also on top of communicating with me given the weather delays, and what I could expect for them coming out. Five stars!"
