Weatherization is the foundation for your home, regardless of how you heat (and cool) it, you want to keep that temperature inside. There are two main aspects of weatherization: air sealing and insulation. Air sealing ensures that your home doesn’t have leaks. Once leaks are under control, insulation can do its job by keeping indoor temperatures stable at a comfortable level. The combination of insulating and air sealing a building has many benefits, including maintaining a more consistent temperature, controlling moisture, keeping pests and pollutants out, and saving money on energy. 

Efficiency Vermont’s Home Performance with Energy Star (HPwES) program covers 75% of project costs up to $2,000 or $5,000, depending on income, for weatherization projects. Low-income households can receive free weatherization through the Weatherization Assistance Program. Up to an additional $8,000 in federal incentives will become available to eligible homeowners through the Inflation Reduction Act. The IRA incentive programs are not yet available as of November 2022.
