Removing moisture between the glass in double-pane windows typically requires replacing the glass panes. In some instances, the whole window will need to be replaced, as the build-up is likely caused by broken seals and excess condensation, as stated by StanekWindows , a window repair and replacement company.
To reduce the likelihood of condensation build-up throughout the home:
Step 1: Lower humidifier settings, or reduce their use.
Step 2: Use a moisture-eliminating product.
Step 3: Utilize bathroom and kitchen fans.
Step 4: Use ceiling fans to circulate the air.
Step 5: Open the windows to release the warm, moist air.
Step 6: Raise the window temperature.
The window temperature can be increased through a higher thermostat setting, or through the use of curtains or drapes.
Step 7: Install weather stripping.
Step 8: Install storm windows.
Step 9: Move plants away from the windows.
Step 10: Utilize a dehumidifier.
Step 11: Utilize an air-to-air exchanger.
Step 12: Install a window insulation kit.
When installed on the window's interior, these kits create a better seal around the window and can reduce condensation build-up.
Condensation between the glass on double-pane windows is likely the result of a damaged seal, and the glass or entire windows likely need to be replaced, but the steps indicated above should reduce overall condensation in the home to help prevent build-up.
