As most of you I have become much more aware of the leakiness of my house. We pulled up all our carpet recently and are going to stay with the hardwood underneath with some area rugs. I pulled up the trim along the walls and in the mornings when it's really cold, I can feel cold air coming in along the edges of the walls/floors. I'm thinking of caluking all the areas where the walls meet the floors before putting the trim back in. Anybody else done this and are there any "gotchya"s to be aware of?
