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 do I properly install weatherstripping on a window?
Proper weatherstripping installation involves cleaning the surfaces where the seal will be applied. For adhesive-backed types, ensure the window frame or sash is dry and free of dirt or old adhesive. Cut the weatherstripping to the correct length for each section. For V-strip or foam tape, apply it along the edge of the sash where it meets the frame when closed. For tubular gaskets, they often fit into a channel or can be adhered to the frame itself. Test the window's operation to ensure it still closes and locks securely.
