Sources of Air Leaks in Your Home

Weatherization

Warm air leaking into your home during the summer and out of your home during the winter can waste a substantial portion of your energy dollars. One of the quickest dollar-saving tasks you can do is caulk, seal, and weather strip all seams, cracks, and openings to the outside. You can save 10% or more on your energy bill by reducing the air leaks in your home.

Draft-Proofing and Energy Saving Tips.

The materials you need to seal the gaps are inexpensive. You can purchase many of them at local hardware stores and install them yourself. You can prevent warm or cold air leaks around your window and doors by applying weather-stripping or caulking to windows, and by putting weather-stripping along the side and the top of exterior doors. Baseboards on outside walls leak air too, so prevent this by using paintable or clear caulking along the top and bottom seams, or take the baseboard off to caulk between the wall and the floor. Install electrical outlet gaskets behind plugs and wall switches on your outside walls to keep them insulated.
Your attic might be a source of heat loss as well, so be sure your attic hatch is weather-stripped. If your windows are getting old, consider replacing them with energy-saving models from House Smart Home Improvements.
You can check for air leaks around your house yourself by using incense (it’ll either glow red or the smoke will trail towards the leak), or get a professional energy audit that makes you eligible for government rebates. To save on heating in the winter, turn your thermostat down a degree and wear sweaters and slippers in the house. As well, use area rugs on bare floors. Clean or replace the air filter in your furnace monthly to increase its efficiency.

How to draft proof your home:

  • It’s good to start at the bottom of the house and work your way up.
  • Remove any old, damaged caulk or weatherstripping before you begin.
  • Caulk around baseboards, sump pump lids, openings in the attic and between an uninsulated attic or basement and the living areas of the house. Seal the top of foundations for added efficiency.
  • Use a smoking incense stick to find leaks or run your hand over windowsills, doors and walls to feel for cold drafts.
  • Doors get warped by use and weather, leaving gaps between the door and frame. If your exterior doors are drafty, caulk between the doorframe and the wall and add weatherstripping along the top and edge of the door. For added protection, you can also put weatherstripping along the vertical doorstop to press against the face of the door when closed.
  • Install a door sweep on the bottom edge of your door, or attach weatherstripping along the bottom of the door or on the threshold. Weatherstripping attached to the door itself needs to be extra durable.
  • Use weatherstripping and caulking to seal around windows.
  • Joints shift over time and with changes in moisture and temperature, leaving gaps and cracks. Use caulking to seal the spaces between interior joints, around non-opening windows and spaces around water pipes and vents. Choose a caulking that is appropriate to the task. Refer to the Buyer’s Guide for information on selecting a product.
  • You can purchase gaskets that fit behind the cover plates of electrical outlets and lighting fixtures to reduce leakage. Caulk the edges of these gaskets.
  • Child safety plugs fitted into infrequently used electrical outlets can help reduce heat loss into exterior walls.
  • Hang interior window coverings to help regulate temperature. See our Shade Your Windows tip to learn more.
  • Cover single-paned or inefficient windows with plastic in the winter.
  • It is possible to over seal your house, leaving it prone to mold or carbon monoxide issues. While it is unlikely to do so with weather stripping and a caulking gun, keep in mind that controlled air circulation is essential for a healthy and comfortable home. Have an electrician install a dehumidistat in your bathroom. These devices can be set to automatically turn on the fan when moisture levels get high. See our Upgrade Your Ventilation tip for more information.
