Weatherization Assistance Program (Wisconsin)
Last updated August 2026
Wisconsin's Weatherization Assistance Program improves the energy efficiency of low-income homes, run by the state through a network of local agencies. It makes the home warmer in winter, cooler in summer, and cheaper to heat, and the improvements stay with the building, so the savings repeat for years.
Here is the part that saves you a step: you do not apply for weatherization separately. If you are income-eligible based on your WHEAP energy-assistance application, your information is referred to the local weatherization agency, which contacts selected households. So the door to weatherization is the WHEAP application at energybenefit.wi.gov.
The income line matches WHEAP: 60 percent of Wisconsin's state median income. For 2025-2026 that is $3,201.75 a month for one person, $4,187 for two, $5,172 for three, $6,157 for four. A working household fits under that line more often than people expect.
The work starts with an energy audit. An auditor inspects the home and decides what will help most. The services differ per home, based on how it was built and its condition. Common measures include insulating attics, walls, and floors. Sealing air leaks. Insulating or replacing the water heater. Efficient lighting. Repairing or replacing the furnace.
There is more than insulation. Crews test and possibly replace an inefficient refrigerator, perform a general health-and-safety inspection, and leave you with maintenance and energy-saving guidance. It is a whole-home approach, not a single fix.
One eligibility boundary to check: weatherization is funded partly with state Public Benefits money, which can only be used on buildings served by a participating electric utility. Customers of certain cooperative or municipal utilities that run their own program may not qualify, so ask your WHEAP agency. Weatherization, WHEAP, and the furnace program all sit under Home Energy Plus, delivered by county agencies, tribes, and community organizations.
