Air sealing is the process of filling the gaps and cracks in a home’s exterior to prevent air leakage. Leaks in your home can waste energy, making it more difficult to maintain a comfortable temperature inside. Drafty windows, doors, and walls allow air to enter and escape your home, causing your heating and cooling systems to work harder and use more energy. Allergens and pollutants can also enter your home through these leaks, affecting the air quality. Sealing these gaps and cracks can boost your home’s energy efficiency, save money on your utility bill, and improve air quality. In this blog, we will discuss what exactly air sealing is and how it can benefit your home.

What Is Air Sealing?
As mentioned above, air sealing fills gaps and cracks in your home’s exterior to prevent air from leaking in or out. This can be done using various materials such as caulk, weatherstripping, sealant, and more. The process begins with thoroughly inspecting your home to identify areas where air leaks and then addressing those areas with the appropriate materials. The goal of air sealing is to create a tight protective shield around your home that prevents unwanted air exchange.
Why Is Air Sealing Important for Home Energy Efficiency?
Air sealing is crucial for home energy efficiency because it helps to reduce the amount of energy needed to heat and cool your home. When leaks are in your home’s exterior, heated or cooled air can escape, forcing your HVAC system to work harder to maintain a comfortable temperature. This leads to higher utility bills and unnecessary energy use.
How Much Can You Save On Utilities By Sealing Your Home?

The amount you can save on utilities by sealing your home will vary depending on several factors, such as the size and age of your home, the extent of air leaks, and climate. However, studies have shown that homeowners can typically save 10-20% on their energy bills after completing air-sealing measures.
Does Air Sealing Help Improve Indoor Air Quality?
When outside air enters your home through leaks, it can bring in pollutants, allergens, and other harmful particles that can affect your indoor air quality. Air sealing helps to prevent this, creating a cleaner and healthier indoor environment for you and your family.
Where Are the Most Effective Places to Air Seal?
The most effective places to air seal in a home are where there is the highest potential for air leaks. These include areas around doors and windows, electrical outlets, unfinished spaces like attics and basements, and any cracks or gaps in the exterior walls. At AES, we offer no-cost home energy audits that can identify the key areas where you are suffering the most energy loss. This will help you maximize your air sealing efforts and save money.
