Why is there Moisture Inside my Windows?

If you notice moisture or condensation forming inside your windows, it could be an indication of an issue with the window or the indoor environment. Here are a few possible reasons why moisture may be present inside your windows:

  1. Poor insulation: Inadequate insulation around the window frames can allow warm indoor air to come into contact with the cold glass surface. When the warm air cools down, it releases moisture, leading to condensation on the windows.

  2. High humidity levels: If the humidity inside your home is consistently high, it can contribute to condensation on the windows. Daily activities such as cooking, showering, or drying clothes indoors can release moisture into the air, which then condenses on the cooler window surfaces.

  3. Leaking or damaged windows: Damaged or poorly sealed windows can allow water vapor from the outside to seep inside, causing condensation. This can occur if the window seals are worn out, the glass is cracked, or there are gaps between the window frame and the wall.

  4. Indoor moisture sources: Certain indoor activities, like using humidifiers excessively or not venting moisture-producing appliances (such as clothes dryers) properly, can increase the humidity levels in your home. This excess moisture can then lead to condensation on windows.

  5. Cold outdoor temperatures: During cold weather, the temperature difference between the indoor and outdoor environments can cause condensation to form on the windows. If your windows are not well-insulated or have single-pane glass, they may become colder, making condensation more likely.

To address moisture inside your windows, you can take the following steps:

  • Ensure proper ventilation in your home by opening windows or using exhaust fans in areas prone to moisture, such as the kitchen and bathroom.
  • Use dehumidifiers to reduce indoor humidity levels.
  • Check for any leaks or damage in your windows and have them repaired or sealed if necessary.
  • Improve insulation around windows by adding weatherstripping or caulking to reduce the temperature difference between the indoor and outdoor surfaces.
  • Consider upgrading to more energy-efficient windows with double or triple glazing, which can help reduce condensation.

If the issue persists or if you suspect a significant problem with your windows, it's advisable to consult a professional window contractor or a qualified technician who can assess the situation and provide appropriate recommendations.

Removing your poorly sealed windows and replacing them with newer ones is your best bet to restore insulation once window condensation has been identified. This removes the source of the condensation, giving you a fresh start and windows that will last for many years and backed by a warranty.
