It's winter time again and our windows are really drafty so I am going to start replacing some of the old cracking caulk around the windows on the exterior of the home. In the process of examining my windows, I noticed that there is what looks to be a drip edge above the window but underneath the lintel. See attached images for reference.
My questions are:
- Is this actually a drip edge (it is plastic and not metal)?
- If so, is the drip edge normally installed under the lintel instead of on top of it? I haven't seen that done before.
- If it is a drip edge, should it have been sealed with caulk between it and the lintel as shown in the picture?
- If it is not a drip edge, can I caulk it to prevent drafts that may be caused by it?
