What’s the Best Method for Sealing Windows Against Drafts in an Older Home?
Sealing windows against drafts is a crucial step in maintaining a comfortable, energy-efficient home. Especially in older houses, window seals can deteriorate over time, allowing cold air to seep in and warm air to escape. The result is a drafty home that struggles to retain heat, leading to a spike in energy bills and a drop in comfort. But fear not, there are several solutions available to you. This article will guide you through the best methods available to seal your windows against drafts, helping you to save energy, reduce your heating bills, and create a cozy environment all year round.
Weatherstripping: An Easy and Effective Solution
Weatherstripping is a popular method for sealing windows against drafts. It involves applying a thin strip of material around the edges of your window frames to block out drafts. Weatherstripping is a quick, cost-effective solution that you can easily accomplish by yourselves.

Before applying weatherstripping, clean the surface of your windows. Once the window surface is clean, measure and cut the weatherstripping to fit your window frames. With the adhesive side, stick the weatherstripping around the edges of the window frame. Press firmly to ensure a good seal.
Weatherstripping comes in various materials, including foam, rubber, metal, and vinyl. The best type for your home will depend on your specific needs and the condition of your windows. For example, foam weatherstripping is excellent for sealing irregular gaps, while vinyl weatherstripping is durable and resistant to moisture.

Caulking: Providing Long-Term Insulation
Caulking is another effective method for sealing windows against drafts. It involves filling the gaps around your window frames with a flexible, waterproof material. This material hardens upon drying to create a tight seal that prevents drafts and offers long-term insulation.
Before you start caulking, ensure your windows are clean and dry. Next, apply the caulk around the window frame using a caulking gun. Be sure to apply it smoothly and evenly to provide the best seal.
Caulk comes in several different types, including silicone, latex, and acrylic. Silicone caulk is typically the most durable and weather-resistant, making it an excellent choice for sealing windows against drafts. However, latex and acrylic caulks are easier to apply and clean up, making them a good option for beginners.
Window Film: An Invisible Barrier Against the Cold
Window film is a transparent, plastic material that you apply directly to your window glass. It creates an invisible barrier that helps to prevent drafts and heat loss, improving the energy efficiency of your home.
To apply window film, start by cleaning your windows thoroughly. Then, cut the film to the size of your window glass and apply it using a squeegee to smooth out any bubbles or wrinkles. Some window films also require a heat source, such as a hairdryer, to shrink the film and create a tighter seal.
Window film is an excellent option for adding an extra layer of insulation to your windows without altering their appearance. It’s also a great choice for older homes with unique or decorative windows that you don’t want to cover with weatherstripping or caulk.
Draft Snakes: A Simple, Low-Tech Solution
If you’re looking for a simple, low-tech solution for sealing windows against drafts, consider draft snakes. These are fabric tubes filled with insulating material that you place along the bottom of your windows to block drafts.
To use a draft snake, simply place it along the bottom of your window frame where the window meets the sill. The draft snake acts as a barrier, preventing cold air from seeping in and warm air from escaping.
Draft snakes are a great solution for those who want a quick and easy way to seal windows against drafts. They’re also an excellent option for renters or those who don’t want to make permanent changes to their windows.
Insulated Curtains: Adding a Layer of Warmth
Insulated curtains, or thermal curtains, are specially designed to insulate your windows and prevent drafts. They work by trapping air between the window and the curtain, creating a barrier that prevents heat loss.
To use insulated curtains, simply hang them as you would regular curtains. Make sure they cover the entire window, from top to bottom and side to side, to provide the best insulation.
Insulated curtains not only help to seal your windows against drafts, but they also add a layer of warmth to your home. Plus, they come in a variety of styles and colors, making them a stylish as well as practical addition to your home.
Spray Foam: For Larger Gaps and Cracks
Spray foam is another solution that is specifically formulated for sealing larger gaps and cracks around windows. It is an excellent option when traditional weatherstripping or caulking is not enough to tackle the size of the air leak.
Before you start using spray foam, it is crucial to examine your windows carefully. Look for any significant gaps or cracks that may be causing drafts. Once you’ve identified the problem areas, you can start applying the spray foam.
Ensure the area you’re working on is clean and dry. Shake the can before use, then attach the applicator straw to the can’s nozzle. Spray the foam into the gap or crack, starting at one end and moving slowly to the other. Keep in mind that the foam will expand significantly once it’s applied, so it’s best to fill the gap about 50% of the way.
Spray foam, which often comes in polyurethane and latex types, hardens and seals the space thoroughly, preventing cold air from entering and heated air from escaping. It’s a strong and lasting solution for larger air leaks. However, be cautious during the application as it can be messy and difficult to remove if it lands on unintended surfaces.
Storm Windows: The External Shield
Storm windows, an additional layer of window, can be installed on the inside or outside of your existing windows. These act as an extra shield against drafty windows, providing a pocket of insulation that reduces air leaks.
Before installing storm windows, measure your window frame carefully to ensure a proper fit. Remember that correct installation is key to maximizing the benefits of storm windows. They should be securely mounted and sealed to prevent drafts and potential damage.
External storm windows are often constructed from plastic panels or glass. They offer the benefit of being less visible than internal storm windows, preserving the view and appearance of your existing windows. Internal storm windows, on the other hand, are easier to install and remove, making them a flexible option for varying weather conditions.
Storm windows, while requiring a more significant initial investment, provide a long-term solution for sealing window drafts. They also offer additional benefits such as noise reduction and protection against damage to primary windows.
Conclusion: The Importance of Sealing Windows Against Drafts
A drafty older home can lead to increased energy bills and a less comfortable living environment. However, with the right tools and techniques, you can effectively seal your windows against drafts. From weather stripping and caulking to window film and draft snakes, there are options to suit different needs and budget. Larger gaps might need spray foam, while storm windows can provide an additional layer of protection.
Before deciding on the best method, consider the specific needs of your home, the condition of your windows, and your DIY skills. Remember, a well-insulated home isn’t just about comfort — it’s also about energy efficiency and reducing the environmental impact. So, take the time to identify and address air leaks around your windows doors and enjoy the warmth and savings that come with it.
