The weather's getting colder and that means it's time to check your doors and windows to ensure they aren't letting cold air in or heated air out. (Insert Dad's voice here: "Do you think I want to heat the whole outside?!?")
Here's something you may not have considered. Insulate your switchplates and electrical outlets on exterior walls to save energy and money. You can get pre-cut foam sheets to fit behind the plates and all you need is a screwdriver. To keep ants away, put a few drops of peppermint oil on the foam before installing it.
When my mom had a blower door test done in her old house it was amazing watching the smoke actually trickle out around the sockets. Also the hole in the door frame where the latch goes. If the hole is all the way through the wood, cold air just pours in. Before we insulate the sockets in our new house I want to find out what kind of foam those are made of, though.
