If your home is too hot in the summer and too cold in the winter, read on.
Air passing through walls -- whether they are insulated or not -- can cost you big bucks. To slow that air flow, all you have to have are gasket plugs and switches. The gaskets are quite inexpensive and usually are available in packs of 12 or so. Installation is easy; a screwdriver is the only tool you will need.
Make sure to turn the power off before you begin. Then, remove the cover plate, place the gasket over the switch or plug, and replace the cover. How about that? A home improvement that you can accomplish in less than a minute.
