Sealing Air Leaks Ensures the Conditioned Air You’re Paying for Stays Indoors

Sealing Air Leaks Ensures the Conditioned Air You're Paying for Stays IndoorsSure, there are more interesting, high-tech ways of saving energy than sealing air leaks in your Indiana home. However, few others pay you back as much or as fast. Homeowners can immediately cut cooling and heating costs as much as one-third by the simple, unglamorous task of caulking and weatherstripping cracks and gaps in the house that allow heat gain and loss. The cumulative size of all small leaks in a home can be the equivalent of cutting a 3 foot by 3 foot hole in an exterior wall. Leakage from some houses can total as much as 60 percent of conditioned air. Detecting and sealing air leaks is a low-cost no-brainer for increasing home energy efficiency.  Here are some tips to get the job done:

  • Locate air leaks by using smoke from a stick of lighted incense to detect tiny air currents. After closing doors and windows and turning on exhaust fans, wave the smoke around doors and windows, electrical outlets, plumbing entry points, ceiling lights and attic doors. If the smoke stream deflects, you’ve found a leak. Another useful method is to turn on interior lights at night, then step outside and look for any spots where light leaks out of gaps or cracks.
  • Close the gaps around movable surfaces of doors and windows using adhesive-backed foam or rubber weatherstripping.
  • Fill structural holes and cracks 1/4-inch or smaller with caulking. Fill larger spaces with expandable spray foam.
  • Seal large gaps where plumbing pipes enter the house or where vent pipes pass from living spaces into the attic with expandable spray foam.
  • Use foam or rubber weatherstripping to seal gap around the attic access hatch.
  • Install gaskets behind A/C electrical outlets and switch plates.
  • Make sure the fireplace flue closes tightly and keep it shut when the fireplace is not in use.
  • Close leaks around fireplaces and furnace and water heater vents with sheet metal,  heat-proof sheetrock or fire-resistant caulking.
