No matter how you look at it, drafty windows suck money from your bank account. Replace them and you’re looking at a hefty sum. Leave them as is, and watch your heating bills skyrocket.


If you’re not ready to take on the expense of replacing windows, these DIY projects can fix drafty windows and save you some money.



  • Check the wood around the windows for rot. Small chips or gaps can be patched with an epoxy wood filler; if larger sections of the wood has rotted, you’ll need to replace the entire sash or frame.

  • If you can feel cold air coming in around the sash, frame, and window dividers, you need to seal the gaps with new caulk or weatherstripping. Replace any damaged weatherstripping with a quality product, like Frost King’s Silicone Weatherseal, which fills gaps tightly, has built-in memory, and is guaranteed not to harden, crack, or freeze for 10 years.

  • For the best seal, cover drafty windows with a Frost King Window Kit, which includes a crystal clear plastic sheet that shrinks tight and wrinkle-free with an ordinary handheld hairdryer. This easy and affordable solution can help with drafts, window condensation, and even a broken window pane. Watch our video for installation tips.
