Why would my basement beam be sagging so much?

Can I replace joist bridging in one bay with partial blocking?

Yeah, you can. That bridging serves to hold the joist in position and to transfer load from one joist to another. It's not a critical component, really. It just improves overall stiffness in the floor,...

How much of a problem is this rotted joist end and what should I do about it?

Carve out the rotten part and don't try to restore it, If the rot is too bad to continue using this joist repair it (using new wood and repair plates/sistering etc) or replace it.

Follow up to an old question

Is a 3-1/2" x 3-1/2" 1.8E parallam PSL header sufficient for 3' door opening in load-bearing wall?

No. The bare minimum bearing header is a double 2x6 (the 5¼" size for this product). That's even questionable for this span. I'd want to see a double 2x8 or 2x10. It doesn't matter that you have ...
