Finding and Sealing Air Leaks

Posted May 08, 2014 by Gabriel Posternak

Energy loss refers to the loss of heat through the walls, floors, and ceilings in your home. Especially when there are cracks or weaknesses in your walls or around doors, pipes, and ducts, air escapes your home and costs you hundreds of dollars. Thankfully, energy loss can be prevented.

You can save money and conserve energy by finding and sealing air leaks to prevent major energy loss in your home. All it takes is a little time and know how.

Know The Trouble Spots

Before you begin your inspection to find any air leaks, you should arm yourself with the knowledge of where air leaks are most likely to occur. When you perform your inspection, you will want devote extra attention to these potential trouble spots:

  • Windows
  • Doors
  • Outlets
  • Air Ducts
  • Pipes
  • Fireplace Flue
  • Recessed Light Fixtures
  • Wall Around Fireplace
  • Attic Ceiling
  • Attic Access Door
  • Drop Ceilings
  • Switches
  • Plumbing
  • Utility Access Points


You can perform an inspection fairly easily by yourself. To start, close all doors and windows. If you have a fireplace or chimney, make sure the flue is closed. You will want to turn off any gas appliances. Before you start the inspection, turn on any ceiling, exhaust, or floor fans. This will draw air in to the house.

Focusing on the trouble spots, inspect your home by running your hands over potential areas where an air leak could occur. You can do this with your hands slightly wet to increase sensitivity, and feel for any small drafts. Another way you can do this is to use an incense stick and watch for the smoke to alert you of an air leak.

Once you have located and noted where your potential air leaks are, you can start repairing or reinforcing to prevent further energy loss.


For door and window frames, as well as around pipe fixtures and air ducts, you can use simple caulking to seal and prevent air leaks. Caulking is fairly inexpensive and can be found in any hardware store.

Weather Stripping

For areas that require movement, such as doors, you can use weather stripping to prevent drafty air leaks. Weather stripping is extremely simple to install and can be found in hardware stores everywhere. Once applied, it can prevent drafts while still allowing the movement required to open and shut the door.


If you have located weak areas in your home’s insulation, you might look at filling in or replacing your insulation. Thanks to government programs to help conserve energy, there are multiple options for energy saving insulation. Unless you have experience, you might seek information on what insulation is best for your home, as there are different materials and thicknesses available.

Energy loss accounts for hundreds of dollars of wasted dollars each year. Each of those hard earned dollars are floating through your walls, floors, ceilings, and doors. Thankfully, you can easily find and seal the air leaks that are responsible for the lost energy in your home.
