How to Seal Power Outlets and Switch Airleaks

Duck socket sealers to insulate interior and exterior power outlets.

In the quest to better seal up my home from the winter weather, I found many websites that suggest searching for air leaks. One low cost area is the gap in the power outlets and wall switches. And a quick search shows that a pack of 24 socket sealers by Duck brand costs only $2.88 (add-on item) from Amazon. Even though I wasn't able to use all 24 due to outlet shape, I did get some of them to work. Because it was only a $2.88 investment, it was well worth it to improve energy efficiency.

What to verify before purchasing Socket Sealers? For me, I was disappointed because most of the socket sealers did not fit in the power outlets at my house. My outlets look more like GFCI outlets, with a rectangular cutout by the power outlets instead of two individual circles. Take a quick look at the picture of the package to get a good idea.

Luckily for me, I had a few interior outlets in the style required by Socket Sealers. Installation of the socket sealers to reduce air draft was easy and only requires a small screwdriver. I didn't even both shutting down the power, though to be extra careful, it might not be a bad idea. The socket sealer is Styrofoam without any sticky mess to deal with. The holes pre-cut holes on each sealer matched very snuggly with my existing outlet.
