Weatherization Assistance for Connecticut Residents

Designed to assist low-income households for free.

Say goodbye to soaring energy bills and hello to a cozier living space.

Reduce Your Heat and Utility Bills

Understanding Weatherization

Weatherization helps improve energy efficiency by sealing air leaks, insulating walls, attics, and floors, and optimizing heating and cooling systems. By reducing the energy needed to heat or cool a building, weatherization lowers energy bills for homeowners and tenants, saving them money in the long run. This makes your home healthier, cooler in the summer, and cozier in the winter.

No-Cost Weatherization

The US Department of Energy funds the Weatherization Assistance Program and assists low-income persons in minimizing energy-related costs and fuel usage in their homes through retrofits and home improvement measures.

Eligibility

The Weatherization Assistance Program uses the same eligibility criteria as the Connecticut Energy Assistance Program. The eligibility is set at 60% of the State Median Income. For multi-family dwellings, at least two-thirds of the tenants must be income-eligible. Learn more.

The windows weren’t really insulated, the walls were not insulated, the floors were cold during the wintertime. We would have to pretty much hibernate upstairs in the bedrooms because it was just so cold. Now … we can cook in the kitchen and walk around barefoot and I don’t have to worry about my children getting sick.
