1. Store Insect Screens

Properly storing your insect screens each season will help protect them from ice and other damage.

Here’s how:

  • Start by removing the insect screens from the window frames.
  • Clean your insect screens by laying them flat on a solid surface and brushing gently with a soft brush and soapy water.
  • Store your insect screens upright or flat in a clean, dry area. For more detailed instructions, visit our Help Center.

2. Limit Drafts

Drafty windows and windows that are not properly insulated can increase your home’s energy use each year.

Here are three ways to help better insulate your home:

  • Check weatherstripping around windows and doors for any leaks and replace any that show gaps, damage or permanent compression. Find more information on replacing your weatherstrip, here. 
  • Fill any additional air gaps around the window with sealant.
  • Check to make sure all windows and doors are fully closed and locked. Windows that are closed and locked provide a tighter seal and greater energy efficiency.

3. Understand the Role of Humidity

Condensation appears when warm, moist air meets cooler surfaces, like a cold drink in the summer or the glass on your window on a cold winter’s day. Condensation will appear from time to time on even the best-performing windows—in fact, it’s often noticed more on high quality windows, because of their energy efficiency. You can help control condensation by reducing the humidity levels inside your house.

Here are a few ways to reduce interior humidity levels:

  • Use a dehumidifier
  • Turn the humidifier on your furnace down (or off)
  • Keep blinds or curtains open during the day
  • Leave ceiling fans on to promote air movement
  • Use an exhaust fan in bathroom areas when showering
