Outside bottom rubber/plastic weather seal

Hi there, and Happy Holidays. I'm looking for a replacement bottom seal for my windows. I believe these are single hung windows (pic of full window attached). I searched everywhere on the window for the make/model, but I couldn't find any identifying markings. I have included two pics of the windows and the bottom outside seals - one window from the front of my house, and the other window that faces the back of my home. They both have the same dimensions. However, as you can see from the pics( the window that faces the front of my house ) the rubber bottom part of the seal is completely gone, and all that's left is the jagged plastic like edge of the top part of the seal. It seems like the seal is made of two parts, the top part of the seal that is attached to the window is hard plastic, and the bottom part is made of rubber and has a lip shape. The other pic is of the back facing window where the seal is still in good shape, so I included that pic as a reference. The seal faces the outside only on both windows and measures 33 3/8 inches (the same width of the window).. Do you carry this replacement seaI? If so. I would need 2 of them, both sets of my front facing windows have the same issue. Please keep me posted, or if you need any more information. Thank you in advance. Cheers, - Ken

Hello,
We'd be happy to look into this for you but we can't be sure if any of our seals would work with yours still installed. If you could remove a less damaged piece and show us an end profile photo, we can go from there. See the video below showing what we'll need to see. Thank you!

Hi Casey thanks for reaching back. I hope the holidays treated you well. Soo It looks like the rubber seal is an extension of the bottom part of the window's sash, so it does not slide out like most other weather seals. It's strange I couldn't find anything comparable online. I was really hoping to avoid buying a whole sash, or window, since the damage is just isolated to that bottom part, and the rest of the sash is in good shape. Anyway, I attached a few more pics. If you or any of your colleagues have any ideas please let me know. Thanks again. Cheers , Ken

Unfortunately, we do not carry a seal like yours that uses a flexible flap to fill the gap between the sash and window sill. It's possible that it may install with a type of kerf base but we can't be sure. If so, you may need to use something like a putty knife or slotted screwdriver to carefully remove it from the sash frame.
