Why does my window have condensation?
Tracking down the root cause of window condensation can be tricky, but in general, condensation occurs when warm, moist indoor air collides with a cooler surface. Because glass is one of the coldest materials in your home, excess water vapor condenses there first, causing that all-too-familiar fog effect. If the inside of your window simply refuses to dry up, we can help you track down the source—step by step.
What to do if windows are winterized?
Hey, it’s nothing to be ashamed of! If you’ve winterized your windows, ruled out the likely causes listed here, and checked for ventilation problems, hiring a home inspector (or a mold and mildew specialist) is your best bet. They’re trained to look for other hidden sources of moisture, like rainwater seeping into your foundation or crawl space. Moving quickly and working with a specialist will prevent further damage to your home, so it can be a smart investment.
Why do plants need to be moved off windowsill?
Plants release moisture into the air as they grow, so move them off your windowsill during the cold season.

Why do windows have condensation?
The main culprit of window condensation is excess humidity. Condensation forms when the warm air inside of your home comes into contact with the cold surface of your window. Because the indoor air has a higher humidity level, meaning its holding more moisture, the water vapor condenses into a liquid on your window pane. When the outside temperature drops, you can expect to see condensation on the inside surface of your windows. Your indoor air is usually more humid because of your everyday living. As you go about your day, you are adding more indoor humidity, increasing the inside temperature. This could be addressed by using a dehumidifier but sometimes this solution cannot fix every condensation problem.
How to prevent condensation on windows?
Presently, there are two different ways to deal with window condensation: 1) either replace the window -- you can usually replace only the glass unit and not the whole window -- or 2) hire a local company to drill holes in the outer pane, clean the windows from the inside, and install one-way air vents to help prevent future condensation.
What is double pane window?
Double pane windows, also called “insulated” or “thermal” windows, are made with two panels of glass sandwiched over a spacer and sealant, creating a space between the panes that is filled with air or with a gas, usually argon or krypton. It is this sealed space that gives the window most of its thermal performance. The spacer may also contain a desiccant material to help absorb any excessive moisture in the air within the sealed space. Interior condensation in a thermal window typically indicates a failure of the seal between the glass panels and/or saturation of the desiccant.
Why is condensation a problem?
Because a breached seal allows fresh air and water vapor to enter the window space, a condensation problem simply becomes a function of nature.

What does condensation in double paned windows mean?
In summary, condensation in double-paned windows indicates that the glazing assembly has failed and needs repair or replacement.
Why do double pane windows expand?
Although double-paned windows appear to be stable, they actually experience a daily cycle of expansion and contraction caused by thermal pumping. Sunlight heats the airspace between the panes and causes the gas there to heat up and expand, pressurizing the space between the panes. At night, the window cools and the space between the panes contracts. This motion acts like the bellows of a forge and is called thermal pumping.
What is the purpose of silica pellets in double pane windows?
In a double-paned window, silica pellets inside the aluminum perimeter strip absorb moisture from any incoming air that enters the space between the panes. If not for the silica desiccant, any moisture in the space between the panes would condense on the glass as the glass cools below the dew point temperature.
What is the dew point in windows?
A critical temperature, known as the dew point, exists where these water droplets will be forced so close together that they merge into visible liquid in a process called condensation. Double-pane windows have a layer of gas (usually argon or air) trapped between two panes of glass that acts as insulation to reduce heat loss through the window.
How does thermal pumping affect seals?
Over time, the constant pressure fluctuations caused by thermal pumping will stress the seal. Eventually, the seal will develop small fractures that will slowly grow in size, allowing increasing amounts of infiltration and exfiltration of air from the space between the panes.

Why is low E glass used?
Low-E glass coating helps block heat or cold from transferring from the outside to the inside of your home. By minimizing the transfer, low-E glass enables the exterior surface of window glass to cool along with the outside air, while the indoor side of the glass remains warmer. When indoor and outdoor temperatures and humidity levels combine in certain ratios, condensation can develop on the Low-E window coating. Alternatively, less energy-efficient windows are less likely to have condensation.
