If you suspect you have air leaks, you’re probably right. Most homes in the U.S. do, and according to ENERGY STAR®, air leakage is responsible for up to 40% of the energy loss in American homes. Yikes! That’s a lot of home energy waste!

As winter approaches, now is the time to inspect your home for air leaks around windows. Leaks reduce indoor comfort and lead to higher heating costs.

If you can see daylight around the edges of a window frame or if a window rattles slightly when touched, air is likely leaking. You may also notice drafts near doors or windows, higher than normal energy bills, cracks or gaps in your home’s exterior, uneven temperatures between rooms or excessive dust. All are indicators that air is leaking.

Caulking and weatherstripping are simple, effective methods for sealing windows. These materials are available in a variety of compounds and forms, each designed for different types of surfaces. Choose the right product and apply it properly to reduce heat loss, improve comfort and lower energy bills.
