How To Fix Drafty Windows

Drafty Windows

When it comes to dealing with drafty windows, you’re not alone. In fact, it’s one of the top concerns from homeowners, especially as it becomes colder and colder here in Michigan. There are a few different reasons that you could be experiencing cold air entering your home. The windows may be old or improperly installed, the seal of your windows may be broken in places, or there could be cracks in the frame or the caulk holding it together. Let’s take a look at a few solutions and see if we can solve this problem once and for all for you!

Storm Windows

Have you replaced your window screens with storm windows? Storm windows provide you with an extra layer of protection to keep cold air outside where it belongs. The plexiglass or acrylic material of an interior storm window will increase your insulation without breaking the bank. Plus, they’re easy to install and will pay for themselves over time thanks to a decrease in energy costs each month.


Weatherstripping is an extremely cost-effective way to reduce drafts in the home. You can quickly apply V-seal weatherstripping along your window sashes, which will still allow you to open and close the windows if needed. There are many different types of weatherstripping and if you aren’t sure which one is right for your home, the Department of Energy has a helpful guide and grid you can check out. You can also look into plastic shrink wrap, which can allow a room to retain more than 50% of its heat.


If you’re looking to create a line of defense against the harsh temperatures outside, pick up some caulk at your local hardware store. Inspect the windows throughout your home to identify any cracks or openings that allow air to enter the home. Clean the windows beforehand to ensure good caulk adhesion. Note that the best time to apply caulk is when the temperature outside is above 45°F. Caulk can also degrade over time and continue to allow air leakages so use this only as a temporary solution as you pursue something more efficient and long-term.

Heavy Curtains

Each year when summer ends, you can switch out your lightweight curtains for a heavier fabric which blocks out UV light and cold air. Many stores sell thermal or insulated curtains that are energy efficient solutions for drafty windows.
