Why Seal and Insulate

Sealing air leaks around your home and adding insulation can help your home be more comfortable and energy efficient and provide up to a 10% savings on your annual energy bills. Simple fixes include installing weather stripping on doors and caulking around windows, while bigger jobs might include sealing leaks and adding insulation in your attic. First, use these resources to choose and prioritize your air sealing and insulation projects. Second, use the how-to instructions to do it yourself, or link to qualified professionals who can help you do the job.
