1. Seal Cracks and Gaps with Caulk

One of the simplest yet most effective ways to stop drafts is by sealing cracks around your windows with caulk. Over time, gaps can form where the window frame meets the wall, allowing cold air to seep in. High-quality exterior caulk is designed to withstand weather changes, making it perfect for long-term solutions. Be sure to thoroughly clean the area before applying the caulk for a smooth, lasting seal.

2. Install Weatherstripping for a Tighter Seal

Weatherstripping is a budget-friendly and practical way to block air leaks around your windows. Self-adhesive foam, rubber strips, or V-seal weatherstripping can be applied to the movable parts of your window, like the sash and frame. This ensures a snug fit while still allowing the window to open and close easily. For older, draftier windows, layering weatherstripping with other methods can provide even better results.

3. Add Insulating Window Film

Window insulation film is an excellent option for older windows that lack double-pane glass. This clear, shrinkable plastic layer adheres directly to the window frame and creates a barrier against drafts. Once heated with a hairdryer, the film tightens to the glass, preventing cold air from infiltrating and reducing heat loss. It’s an affordable and seasonal fix that can make a noticeable difference in energy costs.

4. Invest in Heavy Curtains or Drapes

For an added layer of protection, consider investing in thermal curtains. These specially designed curtains are lined with insulation material that traps heat indoors and keeps cold air out. Beyond their functional benefits, they also come in a variety of styles and colors, allowing you to enhance your interior décor while reducing drafts. Pair them with blinds for even better insulation.

5. Maintain Window Hardware for a Secure Fit

Older windows often suffer from wear and tear that can impact their efficiency. Ensure that locks and latches are working correctly, as locking the window creates a tighter seal. Clean and lubricate any moving parts to ensure they close completely. If the hardware is damaged, replace it to maximize efficiency and minimize drafts.

Taking these steps to prevent drafts in older windows will not only enhance your home’s comfort but also reduce your heating and cooling expenses. While these fixes can significantly improve efficiency, older windows that remain drafty despite maintenance might be due for replacement. Upgrading to modern, energy-efficient windows can provide a more permanent solution and deliver long-term savings.
