Hello,
Built the house in 2000 and installed LP vinyl windows. Don't recall much from when it was first built but these windows leak mostly at the joint of the 2 windows and somewhat at the top at the sides of the bottom window. Joint for the 2 windows is like a U channel on each window that interlocks. On sides is a "fuzzy" strip/seal which should also be replaced. Pictures attached to help see the seal arrangement. Homeowner but capable of changing these out.

Thanks for reaching out to us. Sounds like you need two different weatherstripping styles. We may be able to help, but I'm afraid I can't make a recommendation based on the provided images. You'll need to remove a sample of each type and show me a clear photo of the cross section. We will also need precise, written dimensions. The video below will clarify.
