How to Keep Cold Air Out — Simple Window and Door Sealing Tips

Keep the Cold Outside and the Warmth In

As temperatures drop, even the smallest draft can make your home feel chilly — and drive up your heating costs. The good news? With a few easy DIY fixes, you can stop the cold air from sneaking in and enjoy a warmer, more efficient home.

1. Find the Drafts

Start by walking through your home and checking for cold air leaks near windows, doors, and baseboards. A lit candle or stick of incense can help — if the flame flickers, there’s a draft.

2. Seal Gaps with Weatherstripping or Foam Tape

Weatherstripping is one of the simplest ways to improve insulation. Foam tape or V-strip weatherstripping can easily be applied to door frames and window sashes to stop leaks and create a tight seal.

3. Caulk Around Trim and Baseboards

Use a silicone-based caulk to fill cracks around window frames, baseboards, and even outlets on exterior walls. Silicone holds up well against temperature changes and moisture.

4. Add a Window Insulation Film Kit

Shrink-film window insulation is a quick weekend project that pays off all season. After applying the film, use a hair dryer to tighten it for a clear, invisible barrier that locks in heat.

Final Tip

A few dollars spent sealing leaks can save you up to 20% on your heating bills — and make your home feel warmer instantly.

Stay cozy, save energy, and make this winter more comfortable with easy DIY insulation.
