Insulation and Air Sealing

Home Performance with Energy Star

Ready to insulate your home?

One of the best ways to improve comfort, lower your energy costs and boost efficiency in your home is through insulation and air sealing. These home improvement projects can also help remedy and protect against ice dam issues in the winter and air quality issues year-round. Focus on Energy offers incentives to bring down the cost of insulation and air sealing, and a list of Trade Ally contractors to help you complete the project with ease. Or, if you prefer a hands-on approach to home improvement, check out our available DIY Incentives

Consider an energy assessment

To achieve the greatest benefits, it’s best to look at your home as a system with many different parts working together. The right mix of improvements can make a huge difference in how your home performs. A home energy assessment will identify areas in your home that cause drafts, discomfort and high energy bills. Assessments are performed by trained and certified Trade Ally contractors who will also look at health and safety issues that you may not otherwise consider. Using special diagnostic tools, such as a blower door test, our Trade Ally contractors can locate any air leakage sites and other trouble areas. You’ll walk away with a clear road map of:

  • Where your home is performing well, and where you could benefit from efficiency improvements
  • Specific solutions for comfort, health and safety issues, as well as ideas for lowering energy costs
  • Available financial incentives that cover assessment cost and provide funding for additional work

From there, you can determine which improvements to make, like adding insulation to your attic or walls, and we can put you in touch with a Trade Ally contractor to complete the work. 
Energy assessments typically range between $200-$400 dollars, and in return you’ll gain access to greater financial incentives.

Whether you start with a home energy assessment or you’re ready to jump right to an insulation and/or air sealing project, Focus on Energy is here to help you make your home more comfortable and efficient. Find a Trade Ally contractor to help you get started.
