Hi All,

This post could have just as well have been titled "can I remove this opening" because much of the joists in question are already extended, kinda. So basically I have two openings which make up my front door area. The exterior wall is a front gable made of cinder block w/ brick siding. The old front door used to reside in a block opening but was moved back into a framed (but not headered) 2x3 opening in the early 90's. There is another opening right behind that opening about 2 feet back into the house which is headered and on which several 2x8 floor joints reside. These are floor joists in name alone because there is no living space above them, just walled off odd-angled space. The joists connect on the non-opening end to the stairway box further behind, maybe 4-5 feet back.

What I'd like to do is build a proper 2x4 or 2x6 headered opening for the door and remove the existing headered opening to give the area a little more openness. To do that, I would need to extend most of the joists sitting on that header. Interestingly a few of them are already lapped and set into the block wall. Please don't ask me why they bothered to lap them, unless they cut them all sort and this was the fix in 1951 :p

I've attached a top-down illustration which hopefully shows you what I'm dealing with. You can see which joists extend to the masonry wall and which just stop. There is also a double joist to deal with.

I figure at the very least the two that are not set in the block need to be extended to sit on top of the new header, maybe with beefier scabbing on the top one in the pic. Then I can drill and put some bolts through the ones that are already set in the block. The big question is what to do with the double, as I'm not sure you can extend a double joist with one lap, That one is also a PITA as I can't just move it over since it's set in block.

I realize I need to consult w/ an SE to really do it right, so for now I'd just like some opinions on whether it's worth trying to proceed. Thank you for any advice!

If I understand correctly you want to remove the red header. I do not believe that is possible without installing a flush beam. I don't think glue and bolts are enough to fasten those members together.

A consult from the structural engineer is in order.

Yes correct, the red header. A flush beam is not impossible (I actually have a scrap of LVL which is the perfect size but attaching hangers on to the sides closest to the right of that drawing would be a monumentally tight squeeze. I have no access through the ceiling to the right of the red header.

So you are saying a beefier header built against the block wall would not suffice (noting that the three blue stubs are set directly into the block)? It just stinks that they took the trouble to make those little laps and then set them in the block. Why not just run them all straight back?

I'm no structural engineer but joined joists with no support under the joint doesn't seem correct to me.
The support doesn't need to be in the same position as the red one now. It does need to be under the end of the existing green joists.
