1. Combine window treatments

For protection against the elements, combine blinds, sheer curtains, and heavy drapes. Keep everything closed when it’s cold outside. If it’s cold but not frigid and the room gets sunlight, raise the blinds, open the drapes, and let some sunlight into the room to warm it up.

2. Use window snakes

Window snakes are long tubes filled with sand or water-absorbing material that are placed at the bottom of windows to block drafts and/or absorb condensation. You can also use a rolled up towel or blanket instead. Change these often if they become wet after absorbing moisture.

3. Cover windows with plastic

Window insulation kits, which seal the window with a plastic film, are available at your local hardware store or online. These kits include plastic sheeting that you affix to the jambs with double-sided tape. Once in place, heat the plastic with a hairdryer. The shrinking action will make it look like another glass pane.

4. Fill in any gaps around windows

If you have spaces in your window frames that you can fit your finger into, fill them with a gap filler. A popular choice is foam rope that comes on a roll and in various sizes to fill both small and large gaps. Press it into the spaces and trim off the excess with scissors.

5. Reglaze loose window panes

If your windows are old and wooden, check to see if any of the glazing is missing or loose. If so, reapply glazing in these areas to create a better seal around the glass. Just be sure to do this before the temperature dips below 10 degrees Celsius, as the putty won’t cure properly when cold.

6. Lock windows and apply weatherstripping

Last but not least, one of the most vital steps when winterizing your home is to lock the windows. Window locks pull the sashes together, closing up the space that cold air leaks through. Most of a window’s heat loss occurs through gaps between the sashes and the frame. You can reduce drafts by weather-stripping where two surfaces push together (the horizontals of a double-hung window and the verticals of a casement or gliding window) or where two surfaces slide against each other (the verticals of a double-hung window and the horizontals of a gliding window).

A word of caution: If you are planning on using rope caulk or other sealants that permanently render an operable window non-operational, make sure that you keep at least one working window in each room. Building codes require that basements and sleeping rooms have at least one functioning means of egress.
