Your Guide to Fixing Drafty Winter Windows

Once again, winter is rapidly approaching, and the Midwest region is in store for cold weather and high winds. With these come uncomfortable indoor drafts. If you have drafty windows, the tips below will help you deal with the problem and stay more comfortable this winter.

How to Handle Drafty Windows

Window Caulk

The first step to dealing with problematic drafts is to seal the windows from the outside. Apply window caulk around the outside perimeter of the window frame using a caulking gun. First, however, scrape the surface clean using a putty scraper and sandpaper.

This ensures a firm adhesion and an adequate seal. If you don’t have a caulking gun, another alternative is to apply a roll of rope caulk with your fingers and a wooden dowel. This is a less permanent solution, but it removes easily once winter is over.


Once the frame is sealed, it’s time to deal with leaks coming from the sash or movable parts of the window. From indoors, apply weatherstripping (various types of adhesive-backed foam)—around the edges—particularly between the sash and the frame—to ensure a firm seal when the window is closed. This keeps cold air from seeping in through gaps. You can buy weatherstripping at any home improvement retailer and most department stores.

Shrink Film

Sometimes, the cold is seeping through the window glass itself. Modern double- and triple-glazed windows solve this issue, but it is still common with older, single-pane varieties.

You can address this problem with a roll of plastic shrink film. Cover the window with clear plastic, attaching it to the inside window frame using double-sided tape. You can then shrink it to fit the expanse using a hairdryer.
