If your home experiences any of these problems, it might be a good candidate for an attic air sealing project:
- Drafty rooms
- Hot and cold rooms; uneven temperature between rooms
- High heating or cooling bills
- Ice dams in the winter
- Dry indoor air in winter
- Dust (especially in rooms directly below the attic)
What to Look For
You might also consider hiring a home energy professional to perform a comprehensive energy audit to pinpoint specific solutions for your home and identify potential safety hazards.
Did You Know?
Many local utilities may offer rebates for a professional home energy assessment and certain home air sealing and insulation projects.
Be sure to contact your utility company before beginning a project to see what incentives are available in your area. You can also check for incentives using the DSIRE database for state incentives.
Savings in Energy and Money
The attic is usually where you can find some of the largest opportunities to save energy in your home. By air sealing in your attic, you can stop many major air leaks and help to maintain the desired temperature throughout your home. Combined with attic insulation, air sealing can help to alleviate the formation of dangerous ice dams in the winter.
If your attic is accessible and not too difficult to move around in, and you enjoy tackling bigger home improvement projects, attic air sealing may be a good DIY project. Otherwise, consider finding a contractor to complete the project for you.

EPA's ENERGY STAR program provides great DIY resources to help you get the job done. However, if you find any of the following conditions in your attic, it is recommended that you hire a professional to correct these problems before proceeding:
- Difficult attic access and limited space to work
- Wet or damp insulation, indicating a leaky roof
- Moldy or rotted attic rafters or floor joists, indicating moisture problems
- Kitchen, bathroom or clothes dryer vents that exhaust moist air directly into the attic space instead of outdoors
- Little or no attic ventilation
- Knob and tube wiring (pre-1930), which can be a fire hazard when in contact with insulation
