Hello!

  
My husband and I are in the process of buying our first home! There's some foundation issues so we got an estimate for repairs. The seller got an estimate too. Both foundation contractors went down in the crawl space and took pictures (attached are the pictures the foundation contractor we sent took) and came back with different remedies (attached as well).



One major difference I know is our contractor said they would go through the floor (vs going through the crawl space) to do the work. And it seems like they're replacing the joist vs sistering it (which looks to be what the seller's contractor is proposing to do). But I don't know what's the better solution.



If it's helpful this is what the inspector said about the foundation: 

"*Repairs needed. Multiple rotted structural components were noted on one side under house. The wood bottom plate that sits on brick and supports the entire house is extremely rotted. Some of the ends of the joists that support the floor above are extremely rotted as well. Any rotted material under house (foundation) needs to be remediated to ensure a strong foundation.*"



This is (hopefully) going to be our house–I just want to know which is the correct fix. Any help and insight on this is really, really appreciated. I'm lost with this. 😞

Foundation repair–which is correct? I'm lost.
