I can help
Can you take a look at the following link and answer the questions at the bottom of the sheet? Your answers will allow me to accurately model the loading and size your beam. Thanks
1. So your pocket door is located in the basement and the beam/header will be similar to New Beam #1 in my sketch?
2. What are floor Joist #1 and #2 spans (distance between supports)?
3. Could I get your address so I could look at a Google Streetview of your home to get a general idea of your building configuration?
Is your house right on the corner with a small one car garage on the right side?
Would you be able to take a couple of picture for me and share them on the Chat Window?
I want to make sure I fully understand your configuration.
Maybe one from outside in the area of the project and one inside of the wall in question. It would be great if you could be standing back a bit when you take the picture so I can see the surrounding area.
Let me know when you come back online.
