What Is Air Sealing?

Most houses are not air-tight. Many are riddled with so many gaps and cracks it’s equivalent to leaving a window wide open all year long! That wastes a lot of energy and money. 

Air sealing is the process of locating and closing the gaps and cracks that allow heat and AC to leak out of your home. These openings are most commonly found around attic hatches, basement rim joists, plumbing and wire penetrations, doors and windows, and many other places in your home. Our team will find and seal them before insulating your home to maximize your energy bill savings.

Why Insulate and Air Seal Your Home?

Insulation and air sealing work together to prevent energy loss, keeping your home comfortable year-round and saving you money.

Energy Savings

 Insulation and air sealing solve problems like temperature fluctuations, cold drafts, and hot spots

Air Quality

Air sealing closes off entry points for pollen and other outdoor air pollutants.


Insulating and air sealing reduce the risk of moisture intrusion, pest infestation, ice dams, and more.
