drafty window question

[Steve]

Hi all, I have a basement window that has been drywalled over. I can feel a draft in the basement and know that it is coming from the old window. The outside of the window has a piece of plywood covering it. Is there anyway that i can seal the window from the outside? I would replace the window and drywall around it but it hjas a pipe in front of it, so it is not the best window. Any suggestions on what i should do? thanks Steve

You could cover the outside with plastic, preferably under the plywood to protect it from sunlight. Or you could use foam-in-a-can around the edges of the plywood.
