Air Seal Your Walls

Sealing up all the cracks, gaps and holes in your home will ensure that conditioned air, which has been warmed by your heater or cooled by your air conditioner, stays inside longer. Air sealing can include everything from installing weatherstripping and door sweeps to plugging gaps around your window frames, door frames, behind baseboards and moldings, and around the places where floor meet walls, known as rim and band joists.
