Cloudiness between your glass or moisture between the glass is an indicator of seal failure. If you can wipe the moisture off this is most likely condensation. Seal failure may be covered under your warranty or may be pro-rated.
Condensation forms when warm, humid air contacts a cold surface. Moisture is in the air all around us and warmer air can hold more moisture. As air cools, it contracts and its moisture condenses. When the temperature drops, the first place you will see any condensation is on the windows. Your windows are the coldest surfaces indoors. During colder months, indoor air is much warmer and holds more moisture than outdoor air, which is colder and dry. Warm, humid indoor air cools and contracts; as it contacts the cooler windows, the moisture condenses on the glass.

No, you dont have to buy a new window. Some, but not all windows, allow for the glass to be replaced which is usually less expensive than buying a complete new window. In this instance, we suggest reaching out to a glass company first. Additionally, if you purchased your window from us, you can provide us with the warranty sticker, and we can assist in getting the glass replaced. Please see the next question on how to get replacement parts.
Most windows have a sticker somewhere on the window that should not be removed as it has the necessary warranty information. Its best to have a picture of your issue as well as a picture of the sticker to simplify the warranty process. The sticker on the window identifies not only the window order, but the specific window in question which makes ordering the correct parts much easier. Please note, that most warranties will provide the part, however, labor is not included.
