The Best Solutions for Drafty Windows

Posted in Windows , Replacement Windows

When the weather is comfortable, the last thing you might be thinking about is drafty windows. In January, however, poorly sealed or poorly installed windows might become top-of-mind as it can negatively affect your comfort level. This common window problem also impacts the overall energy efficiency of your home. Since more homeowners seek out solutions for drafty windows in the winter, the warm-weather months are often the best time to seek out a solution.

So, what should you do about drafty windows? Here are your best options.


Weatherstripping is a cost-effective and easy-to-install solution that helps seal gaps and cracks around your windows. A temporary solution, it involves applying strips of adhesive-backed foam, rubber, or silicone to the window frames and sashes. Weatherstripping provides an airtight seal, preventing cold drafts from entering and warm air from escaping. It is an excellent option for windows that have small gaps or spaces. There are various types of weatherstripping available, including adhesive-backed tape, V-strip, and door sweeps. Just keep in mind that this option will degrade at some point and, eventually, you will likely need to replace your windows.


Caulking is another effective method for sealing gaps and cracks around windows. It involves applying a bead of caulk along the window frames and joints to create an airtight seal. Before caulking, make sure to clean the window surfaces and remove any old caulk or debris. Silicone caulk is a popular choice as it provides flexibility and durability. For larger gaps, consider using expanding foam sealant before applying the caulk. Caulking not only prevents drafts but also helps to improve energy efficiency by reducing heat loss. This is best administered by a professional window company.


Representing a bigger investment than other solutions on this list, window replacement is one of the most effective solutions you'll find for drafty windows. Why? Because in addition to getting better, newer, more energy-efficient windows, you'll also have the opportunity to address the frames for the windows and ensure there are no gaps or drafty spots. At Expo Home Improvement, many of our windows are custom made after we meticulously take measurements of each window opening and configure them appropriately.

Insulation Film

Similar to how a Band-Aid covers a wound, window insulation film is a simple and affordable solution to combat inefficient windows. It is a clear plastic film that can be easily applied to the interior of windows. The film creates an insulating barrier that reduces heat transfer and reduces drafts. It's a temporary fix, however, so it should only be considered in the short term.


Window treatments not only enhance the aesthetics of your windows but can also help to reduce drafts. Thick and insulating window curtains or blinds act as a barrier against cold and hot air infiltration. Look for curtains or blinds made from heavy fabrics like wool or thermal-backed materials that provide extra insulation. When closed during colder months, these window treatments can help to minimize drafts and retain heat inside your home.

By employing the right solutions, you can effectively seal those gaps, minimize drafts and create an energy-efficient home. To get a window replacement consultation, contact Expo Home Improvement today by giving us a call at 469-652-8695.
