Yesterday, I went over to our front door and was surprised to feel how cold it was by the door. I was so puzzled. I caulked around the outside of the inside trim of the door last spring when I realized cold air was pouring in there. I couldn't understand why it was so cold. We have a storm door on the door and I'd caulked... what else could be wrong?
I went over to the door and held my hand up to the door frame. First, I put my hand around the outside of the trim. No air coming in.
Then I put it up to the gap between the frame and the door.
I moved my hand around and discovered that the air was coming from where the trim meets the door frame. I wish I could draw a picture to illustrate.... but since I can't--picture an arch of the door trim around your door frame. Last year, I caulked on the outside where the trim met the wall. Now the air was still coming in where the trim meets the frame on the inside edge!
I pulled out a tube of clear caulk from the basement and quickly caulked all four edges where the trim meets the door frame.
This morning I went over by the door frame.
It felt warm. It felt WARM! YIPPEE!
Caulk is a wonderful thing. A very wonderful thing :)
