Tip 5: Prevent Other Air Leakage

There are many places around your house where leakage occurs. Inspect all areas where different materials meet, for example where brick meets wood along the siding, or between the foundation and walls, or between a chimney and siding. Be sure to try to spot any cracks and spaces that could cause air leaks in these places:

• Wherever service wires (cable, telephone or electrical) enter the home
• Around external faucets
• Door and window frames
• Mail slots
• Around air conditioners
• Fans and vents from the kitchen, bathroom or clothes dryer

As the U.S. Department of Energy advises: "For a thorough and accurate measurement of air leakage in your home, hire a qualified technician..."

Once identified, use caulking and weather stripping to seal these problem areas.
