Air Sealing For Winter

Fall is in full swing which means means it is time to start preparing for winter. Getting an early start for your customers will pay big dividends to them down the road. Stopping air leaks for your customers can be your low hanging fruit you can take down early.

When on the premises of your customer’s home, walk around the outside looking for any visual cues that air may be leaking. Typical exterior places to inspect for leaks are outside water spigots, where siding & chimneys meet as well as where the foundation and siding assemble.

Venture inside the home to further inspect for air leaks once the exterior inspection is complete. A common location that is a likely culprit is around electrical outlets. You can combat most air penetration around electric outlets with a simple outlet gasket.

Below is a small list from the DOE for common air leak locations inside a home. Also attached below is a great image highlighting the most likely places for air leaks.
