Why Do My New Windows Have Moisture on the Room Side of the Glass?

Humidity

• Condensation occurs on the room side of your windows when your home has too much humidity. You might notice that the condensation is excessive when you boil a pot of water, do your laundry, or take a long and hot shower. Enhanced humidity in your home also encourages mold and mildew growth, which can lower your home's value.

Temperature Difference

• Temperature can contribute to the rate at which condensation forms on your windows. Condensation will occur more often when warm air hits a cold surface. This is why condensation happens more often in the winter and why it forms on your windows more often than it does on your walls. This often only happens, however, when your home is also humid.

Broken Seals

• Condensation can happen because the seals in your double or triple-paned windows are broken. This causes the condensation to form in the inside of the glass, which you cannot simply wipe off. This tends to only happen on old windows, but it is possible that it would form on new windows if you purchased low-quality windows that were not installed properly.

Condensation Issues

• Condensation can cause several issues. It can make droplets run down your walls and onto items in your home, causing paint to peel and serious water damage on upholstery or wood floors. Condensation in the window can decrease the insulating properties of your multipane windows as well.

Repair

• Repair condensation issues as soon as you notice them by resealing the windows. If the condensation continues, lower your homes humidity with a dehumidifier. Cover pots when boiling water and use ventilation fans whenever cooking or taking a shower. Also, lower your home's temperature so there is not a stark contrast between your room temperature and the temperature of the window.
