I have an Andersen sliding glass door and stationary window. The stationary window is on the left and the sliding door moves right to left. I need to install the weather strip on the stationary window to prevent drafts and cold air from coming in.
I have the weather strip and related stuff that came with it. I don't know the proper way to install it. I know I need to use some type of bead glue or something to make it stick and nails.
If you're talking about the space between the inner door and outer door/window frames, both panels should be removable. (You may need to unscrew some hardware to be able to remove them.) They should in theory lift up and pull out. You should be able to just remove the sliding door, stick on the weather strip, and reinstall the door.
