I kept feeling a draft around my door. I bought weather stripping and placed it around the door. It didn't make a difference. So yesterday I decided to pull the trim off and see if maybe it needed to have some insulation placed. That was an absolute understatement.
It only took me about 45 minutes. Using a prybar to removed the trim and spray insulation to fill the cracks was all it took. I'm afraid of what is lurking behind the window trims now.
On a side note I have to brag on myself. When I was married to husband #1, I would beg him to help me hang pictures or a shelf. Now I do that and build a privacy fence, replaced a door knob, and much more. If you had told me 6 years ago that I would be doing this I'd have laughed at you.
