Air leak control is one of the most important factors when trying to save energy in your home. Blocking drafts reduce heat loss, which will cut energy costs and save you money. Some of the draftiest areas in your home are also the easiest to fix such as the electrical outlets, trim areas, and windows seals. Checking these three main areas will make a noticeable reduction in your energy costs.
Electrical outlets can provide a direct path of air through your walls and into your living space. There are special foam pads that have been approved by CSA International, which fit under the cover of your outlet. The pads will act like insulation, blocking the flow of air. You can also buy insulated plug covers, which have the pad fastened. These can be a little pricier, but you will be saving the difference in energy costs.
Trim areas like baseboards, moldings and window casings can all be areas of energy inefficiency. To stop air flow you can seal all the joints by using a flexible caulk. Caulking comes in clear or a color that will match your trim. Either way both can be painted over. The most effective way to save energy is to carefully remove the old trim and seal the area behind it using a type of expanding foam that will get in all the cracks and crevices. Your old trim can be put back on right over top.
Window seals between the glass and wood should be tight. Every year you should check the glazing and make the material is still intact with no cracked or missing sections. If there is a problem it must be repaired with a putty or glazing compound. Putty usually costs less but needs to be replaced more often. Remove the old material and apply the new with a putty knife, making sure to press it into place. If you have a window that you never open, consider sealing it with a strippable caulk that can be removed easily in case you wish to use it later.
Home owners can usually do an effective job stopping drafts to save energy if they have the time and a little patience. However, if you live in a historical building or older home you may need the help of a professional. Contractors are more experienced in locating and sealing air leaks. Every draft stopped is a step towards energy saving and several small steps can go a long distance towards efficiency and air leak control.
