This was a bad winter here in the Northeast. Bitter cold, lots of snow. Spent a good portion of last fall weatherizing the house, but wasn’t perfect. I kept feeling drafts that I couldn’t find. Black and Decker have released an affordable Thermal Leak Detector for $50 that might be helpful next time around.
