They could be beautiful, historic or even high-quality, but if your windows are letting in air, you’ve got a problem. If you’re facing this issue at your home or business, you may be wondering how to stop drafty windows. Do you have to replace them outright? Are there other effective ways to stop drafty windows? Fortunately, there’s good news. Rather than paying for all new windows to be installed at your location, you have several alternatives for drafty window repair.

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 solutions 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

By prioritizing these energy saving methods, you could save an average of 20% on your energy bills, which will really add up over time!

 
 

Repair, replace or add new weatherstripping

Another 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.

Get a window draft stopper

A draft stopper or draft snake is one of the most simple ways to block cold air from coming in through your window. Draft snakes are tubes or sleeves filled with dense materials that you place on the bottom edge of your window. They are not permanent and can be removed (or sometimes knocked down) very easily.

Cover cracks with nail polish

Very small cracks in your window can be painted with clear nail polish. Don’t try this with any windows that have coating as this can harm window coating.

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. This non-permanent fix is a great way to stop window drafts, but the adhesive often damages surfaces during removal in the spring.

 
 

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. While interior storm windows give a tight seal against window drafts, they don’t change the look of your windows. You preserve their original beauty or historic charm with zero risk of damage to the frame. And they cost less than a full window replacement. They also can improve energy efficiency.
