Drafty windows can be a major source of energy loss and discomfort in your home, especially during the colder months. Fortunately, there are several effective ways to seal old storm windows and stop those pesky drafts without having to replace them entirely. By implementing these simple fixes, you can improve your home’s energy efficiency, reduce your utility bills, and maintain the character of your vintage windows.
Lock Your Windows and Apply Weatherstripping
One of the easiest and most cost-effective ways to seal old storm windows is to ensure they are properly locked and to apply weatherstripping around the frames. Locking the windows helps create a tighter seal, while weatherstripping fills in any gaps or cracks where air can seep through.
When applying weatherstripping, look for materials specifically designed for windows, such as foam, vinyl, or silicone-based products. These can be easily installed by cutting the strips to size and pressing them into place. Be sure to clean the surfaces thoroughly before applying the weatherstripping to ensure a secure bond.
Weatherproof Your Exterior Doors
In addition to sealing your storm windows, it’s also important to address any drafts around your exterior doors. Similar to the windows, you can use weatherstripping and caulk to fill in gaps and cracks around the door frames. This will help prevent air from escaping and cold air from entering your home.
For an extra layer of protection, consider installing door sweeps or draft blockers at the bottom of your exterior doors. These physical barriers can effectively seal off the space between the door and the threshold, further reducing air leaks.
Reglaze Loose Windowpanes
Over time, the glazing compound that holds the glass panes in place on your storm windows can become cracked or loose, allowing air to pass through. Reglazing these loose panes can help create a tighter seal and eliminate drafts.
To reglaze a window, you’ll need to carefully remove the old glazing compound, clean the surface, and apply a new layer of glazing. This process can be time-consuming, but it’s a great way to extend the life of your old storm windows and improve their overall performance.
Use Physical Barriers on Drafty Doors
In addition to weatherstripping, you can also use physical barriers to help seal drafty doors and prevent air leaks. One effective solution is to install door sweeps or draft blockers at the bottom of the door, which create a tight seal against the threshold.
Another option is to use a door snake or draft stopper, which is a long, cylindrical fabric tube that you can place at the base of the door to block air flow. These inexpensive and easy-to-install solutions can make a significant difference in reducing drafts and improving your home’s energy efficiency.
Layer Your Window Treatments
While not a permanent solution, layering your window treatments can also help to seal old storm windows and reduce drafts. Adding heavy curtains, drapes, or insulated window shades can create an additional barrier that traps air and prevents it from escaping.
Be sure to choose window treatments that are specifically designed for insulation, as they will be more effective at blocking air flow and keeping your home comfortable.
Fill in the Gaps to Seal Windows
If you’ve tried the above methods and still have persistent drafts around your old storm windows, you may need to take a more hands-on approach and fill in any remaining gaps or cracks. This can be done using caulk, foam sealant, or even rope caulk, which can be pressed into tight spaces to create a tight seal.
Be thorough in your inspection and sealing efforts, as even the smallest openings can allow significant amounts of air to escape. With a little time and attention, you can effectively seal your old storm windows and enjoy a more comfortable, energy-efficient home.
