Drafty windows can be addressed by sealing air leaks, adding insulation, or considering window upgrades to improve comfort and reduce energy waste.
Stubborn cold spots near windows often stem from air leaks around the frame or sash, poor glazing, or insufficient insulation in the surrounding wall. Start by inspecting for obvious gaps and drafts, then consider temporary fixes like weatherstripping or window film. For more persistent issues, professional assessments can identify specific problems and recommend targeted solutions, ranging from minor repairs to full window replacements.
The effectiveness of any solution can vary based on the specific cause of the draft and the construction of your home.
How can I inspect my windows for air leaks myself?
You can perform a simple DIY inspection for window air leaks using a few common household items. On a windy day, hold a lit incense stick or a thin piece of tissue paper near the window frame, sash, and where the two meet. If the smoke or tissue wavers, you've found an air leak. You can also feel for drafts with your hand. Pay close attention to the edges where the window meets the wall, and around any moving parts of the sash.
