A simple paper test can help homeowners check if their windows are properly sealed against cold air, potentially reducing heating costs. By placing a sheet of paper between the window frame and sash, users can assess the seal's effectiveness. If the paper slides out easily, it indicates a poor seal, often due to worn gaskets or misaligned hardware. Homeowners should inspect gaskets for damage and ensure the closing mechanism is functioning correctly. Temporary sealing solutions can be applied until permanent repairs are made. Regular maintenance of windows and proper ventilation are also essential for maintaining warmth during winter.
