With a little DIY, you can keep your home cozy while reducing heat loss by up to 10%. Seal up drafty doors and windows with self-adhesive foam insulation and easy-to-apply weatherstripping. Plug cracks along window panes, baseboards, walls and vents with caulk or silicon sealant. Another fast fix to keep heat inside: install heavy curtains and keep them closed at night.
