In less than four hours you can significantly reduce air infiltrations by installing gaskets at all electric switches and plugs. You can do your entire home for less than $10. The process is simple: Remove the cover plate, place the gasket, replace the cover plate. If you are handy with a screwdriver, this process can take less than 2 minutes -- start to finish. To test for air leaks, hold a lighted candle next to a plug or switch on the inside of an exterior wall. If the flame flickers, it's time to gasket. And if the flame goes out -- we wouldn't want to have your heating bill. And that's the On The House tip for today.
