Air Leakage
Sealing air leaks in your home “envelope” with caulk, sprayfoam and weather stripping is often the most cost-effective way to improve the energy efficiency and comfort of your home. More than any other time of year, you notice your home’s air leaks in the winter. Most people call these air leaks "drafts." You may feel these drafts around windows and doors and think these leaks are your major source of wasted energy. In most homes, however, the most significant air leaks are hidden in the attic, crawlspace and/or basement. These are the leaks that significantly raise your energy bill and make your house uncomfortable.
In cold weather, warm air rises in your house, just like it does in a chimney. This air, which you have paid to heat, is simply wasted as it rises up into your attic and draws cold air in all around your home—around windows, doors, and through holes into the basement. Locating these leaks can be difficult because they are often not visible to the naked eye. Even if you have plenty of insulation, sealing air leaks is the only way to enhance the performance of your insulation and make for a much more comfortable home.
Call Energy Check to schedule a Home Energy Audit before starting your home improvements. A blower door test will reveal where your home is losing air to the outside world and pinpoint opportunities where — with the proper sealing — your home could do a better job of retaining energy.
