An important, early step to higher home energy efficiency.
Reducing the amount of air that leaks in and out of your home is a cost-effective way to cut heating and cooling costs, improve durability, increase comfort, and create a healthier indoor environment. Caulking and weatherstripping are two simple and effective air-sealing techniques that offer quick returns on investment, often one year or less. Caulk is generally used for cracks and openings between stationary house components such as around door and window frames, and weatherstripping is used to seal components that move, such as doors and operable windows.

Professional energy assessors use blower door tests to help determine a home's airtightness. Our blower door instructional video illustrates how a blower door test is performed, and how your contractor utilizes the diagnostic information provided to identify areas of air leakage in your home, and make energy-saving improvements.
Controlling moisture can make your home more energy-efficient, less costly to heat and cool, more comfortable, and prevent mold growth.
Properly controlling moisture in your home will improve the effectiveness of your air sealing and insulation efforts, and these efforts in turn will help control moisture. The best strategies for controlling moisture in your home depend on your climate and how your home is constructed. Proper ventilation should also be part of a moisture control strategy.

can help you understand the whole picture of your home's energy use, comfort, and safety. An assessment can help you determine how much energy your home uses, where your home is inefficient, and which problem areas and fixes you should prioritize to save energy and improve the comfort of your home. A home energy assessment should be your first step before making energy-saving home improvements, as well as before adding a renewable energy system to your home.
Professional Home Energy Assessments
The U.S. Department of Energy does not offer energy assessments. Visit RESNET or the Building Performance Institute to find a professional assessor near you.

Insulation in your home provides resistance to heat flow and lowers your heating and cooling costs. Properly insulating your home not only reduces heating and cooling costs, but also improves comfort. Installation methods, materials and location all matter. Make sure you know what you're geting and why.
Saves energy and can make your home more comfortable.
Conduct a home energy audit to start building your strategy for weatherizing your home, then learn about air sealing, insulation, moisture control, and ventilation.
Weatherization assistance is offered by states; eligibility requirements vary. Find out how to apply for weatherization assistance.
