Windows and doors are notorious culprits for heat loss as temperatures drop. Begin your weatherization project by inspecting all exterior doors and windows for gaps or damaged seals. Caulk any visible cracks and replace worn weatherstripping to keep drafts at bay.
Install door sweeps on exterior doors to prevent cold air from entering at the threshold. For older windows, consider applying transparent window film—a quick solution that can noticeably improve insulation. Don’t forget mail slots, pet doors, and areas where pipes or cables enter the home; these are often overlooked sources of heat loss.
Pay attention to attic hatches and basement rim joists as well, which can be weak points in your thermal envelope. A weekend spent weatherproofing your home brings immediate savings on heating bills and a tangible increase in indoor comfort through the autumn and winter months.
