Is your house leaking money? If your home is like most, the greatest amount of heat loss is from air leakage; heated air escaping to the colder outdoors through hundreds of tiny holes and cracks around your home.
In fact, up to 40% of your home’s heating bill is spent on heating cold air that has leaked into your home, because hot air has leaked out. The movement of air in and out of your home is increased by the wind, the difference between inside and outside temperatures, and the operation of mechanical systems in your home, such as dryers, exhaust fans and furnaces. It is not unusual for your home to undergo minor expansion and contraction as it adjusts to climate changes, thereby creating air leaks as your home ages and weathers.
But there’s good news! Preventing cold air from entering and exiting your home is easy to do. Of all the
energy saving jobs that need to be done around the house, caulking and weather-stripping
are perfect candidates for do-it yourself projects. A thorough and
effective air sealing job can save up to 15% on your heating bill. Of
course, the first step is to figure out where the cold drafts are
entering and where the warm, moist air is leaving.
