Drafts killing your vibe? Save money on heating bills and fortify your fortress by protecting against air leaks with a few quick applications of expanding foam or caulk. We could make a dirty joke here, but we’ll leave that in your hands.

How To: Check for air leakage by lighting a candle and watching for air movement around windows and existing cracks that disrupts the smoke. Insulate any cracks or holes with expanding foam or caulk made for the materials you need. Just shoot it in, let it dry, cut away the excess, paint, and then stop wearing so many socks around the house.
