Why Windows Get Drafty

Old windows weather over time and even good windows will need some maintenance over the long haul. Glazing putty can fall away, cracks can develop, caulking can degrade, and some types of windows can shrink with age. If your windows are letting in cold air or not working as well as they could, your energy bill is probably suffering for it. That’s why it’s worthwhile to look for ways to fix drafty windows and extend their usefulness.

In fact, there are several ways to breathe new life into your existing windows without shelling out big money for replacements. If you’re looking for the best way to fix drafty windows and improve efficiency, here are six simple methods to consider:

  • Repair, replace or add new weatherstripping
  • Get a window draft stopper
  • Cover cracks with nail polish
  • Wrap the windows with film
  • Reglaze the window panes
  • Use interior storm windows or inserts
 

Repair, replace or add new weatherstripping — One way to prevent drafts from windows is with weatherstripping. Install it along the side sashes and instantly improve the window’s insulation from outside temperatures.

Wrap the windows with film — During seasons when you know you won’t be opening your windows, you may want to apply insulating film. Held by double-sided tape and easy to mount, shrink film can create an airtight seal over your existing windows.

 
 

Repair, replace or add new weatherstripping — One way to prevent a draft from windows is with plastic weatherstripping. Install it along the side sashes and instantly improve the window’s insulation from outside temperatures.

Reglaze the window panes — The glazing putty that seals window panes into the frame is prone to degradation over time. Removing all the existing putty and replacing it with fresh material can improve your windows’ insulation for a few dollars and a little bit of time and effort.

 
 

Use interior storm windows or inserts —The beauty of interior storm windows is that they fit directly into your existing window frames, require minimal effort to install and significantly improve insulation. They don’t change the look of your windows, preserving their original beauty or historic charm, and they cost less than a full window replacement. They also can improve energy efficiency.
