Sealing windows for winter helps prevent drafts and heat loss, improving energy efficiency and reducing heating costs. Common methods include applying weatherstripping, using caulk to seal gaps, and adding window insulation film to block cold air. These simple steps can make a noticeable difference in maintaining indoor warmth during the colder months.

To winterize your windows, first clean the frames and sills, then apply weatherstripping along moving parts of the window. For gaps and cracks, use caulk for a tighter seal. Adding insulating film to windows further blocks out cold air. This process can significantly enhance indoor comfort and reduce energy bills by preventing warm air from escaping, making your home more energy-efficient during the winter.
