The Weatherization Assistance Program (WAP) is a government-funded program to help low-income homeowners and renters lower their energy costs by making their homes more energy efficient. The program saves households an average of $350 per year in energy costs. Energy inspectors visit eligible households to see what work needs to be done to save energy. The inspectors also do a health and safety check to make sure that all energy-related systems are working properly. Trained weatherization workers then make needed energy-saving improvements such as insulating the attic and walls, sealing cracks, wrapping the water heater and pipes, installing storm windows, or making other energy-related improvements. Following the work, an inspector will check to make sure that everything was done properly.

​

WAP services are free. Some homes need more work than others, so the value of the work varies depending on need. The average value is $5500. The cost limit per home is $10,000 in energy improvements.
