Hello,

We have two videos covering wool pile removal that I'll put below for you to review. Some windows have openings in the corners of the sash that will allow you to easily slide the pile out. Yours doesn't appear to have that, so you'll need to follow our cut-out method to remove your existing weatherstripping. Thank you!
