01Sealing Windows and Doors

  • Check for gaps and cracks around windows and doors. Use caulking or weatherstripping to seal these gaps.
  • Apply weatherstripping to the sides and bottoms of doors to create a tight seal.
  • Consider installing storm windows or using window insulation film for added insulation.

02Sealing Electrical Outlets and Switches

  • Remove the cover plates of electrical outlets and switches.
  • Install foam gaskets behind the outlets and switches to seal them against air leaks.
  • Reinstall the cover plates.

03Insulating Attic and Basement

  • Add insulation to your attic to prevent heat loss.
  • Seal any gaps or cracks in the attic floor to prevent air leaks.
  • Insulate your basement walls and seal any gaps in the foundation.

This will not only reduce energy loss and improve energy efficiency, but also enhance indoor air quality by keeping out pollutants. Take these preventive measures to make your home more comfortable and cost-effective.
