Spray foam, patches, and weather-stripping are used to fill in holes and cracks to create a tighter home. Simply adding insulation does not fully address the root of the issue which is outside air making its way into the home.
Identifying Problematic Areas Related To Home Air Sealing
A reputable contractor, through the utilization of diagnostic testing, can work with you to determine areas where a home is leaking air. Winter is an optimum time for a home energy evaluation because the interior of the home varies so much from the exterior home air temperature. A heat map analysis utilizes thermal imaging which can rapidly allow a contractor to identify pockets of cold air within your home.

Attic Sealing Benefits
From a comfort, energy efficiency, and utility savings standpoint, home air sealing is a win. Once all necessary areas have been properly sealed, your home’s interior temperature is better regulated, allowing your home heating systems, like a furnace, to run less. Upon proper completion, there should be less of a variance between the temperatures in rooms throughout your home. Attic air sealing and insulation services are the best way to ward off the risk of ice dams on your roof. In addition, homeowners that have had attic sealing done will notice a quieter home, lower home air moisture and humidity, and a drop in the amount of dust circulating in the air.
