Condensation on windows commonly happens, especially during winter. Condensation forms when moist, hot air inside the house comes in contact with the cool surface of window panes. During condensation, water vapor is converted to water droplets that attach to any solid object such as windows. Condensation on windows is natural, but not doing anything about it could prove to be harmful in the long run. The good news is, it’s possible to get rid of window condensation overnight. And with proper house routines and the right windows, you can prevent condensation from becoming a huge problem. Here’s a list of 10 ways to get rid of window condensation: 1. Improve ventilation. 2. Maintain a consistently warm temperature inside. 3. Keep kitchen and bathroom doors closed. 4. Use lids when cooking 5. Don’t dry laundry inside the house. 6. Invest in better insulation. 7. If you have an ERV or HRV unit, make sure it’s turned on. 8. Open window drapes and avoid blocking your windows. 9. In case of exterior condensation, simply wait for the sun to dry the moisture. 10. Replace your windows in case of condensation between panes.

7. Improve ventilation
Open windows when you can to allow air to
circulate. Install extractor fans, especially in the
kitchen and bathroom where humidity is
constantly high

8. A consistent warm
temperature inside
By maintaining a warm temperature, even on
low settings, you can ensure that surfaces
remain well above the dew point so that
condensation doesn’t occur.

9. Keep kitchen and
bathroom doors closed
These are the most humid areas of the house, and
when you keep them open, you draw moisture
from these rooms to the rest of the house.

10. Use lids when cooking
Steam is released while cooking, contributing to
the moisture in the air. Whenever cooking, use
lids to cover pots and prevent steam from
escaping too much.

11. Don’t dry laundry inside
the house
Drying one full load of damp laundry releases
almost 5 pints of water in the air. If you can, dry
laundry outside the house.

12. Invest in better insulation
If condensation is a recurring issue, consider
reinsulating your walls and installing new
windows

13. Turn on your ERV/HRV unit
Modern houses are built s airtightly to prevent
drafts from entering. This can cause poor air
circulation and too much humidity.

14. Avoid blocking your windows
Closed drapes trap moisture and heat on
window panes. They block air movement across
glass surfaces allowing cool air to pool at the
window sills.

15. Exterior condensation
If you want to prevent exterior condensation,
consider placing tall trees and shrubs to create
a shaded area near your windows. This traps
heat and prevents exterior condensation.

16. Replace your windows
Condensation between two window panes
indicates unit failure. The window unit already
has a leak that allowed moisture to get inside
the air gap.
