I think I demolished a partition wall replaced floor joist.

Hello.

I am renovating the kitchen and therefore tore down a wall to enlarge the space. The kitchen has already been purchased and everything is basically ready for guessing and lowering the ceiling to install hutonit.

Previously, I fixed up my son's room on the upper floor (just put flooring over the existing vinyl and skim coated) and was in there today and thought the floor was swaying a bit in the middle. If you stomp, it makes noise on the changing table and a shelf in there. I have begun to suspect that I dismantled an interior wall that functioned as a floor joist... the house is from the 1920s. What do I do now? I can't install a beam from underneath because I have already bought the kitchen and there's no room for it now... Can I tear up the floor and anchor a new floor joist into the exterior wall? Can I brace to reinforce the upper floor? Is it urgent or can it wait? Grateful for an answer...

You should talk to a designer about how to solve the problem.
It's impossible for us to say anything here as you only describe the problem in text and do not show any drawings of the house.

The only drawings I have are hand-drawn. I assumed it wasn't load-bearing as I have always assumed that all the ones going from the chimney are. Maybe I'm worrying unnecessarily.

What are load-bearing walls in plank houses mainly depends on the direction of the floor joists. Walls that are needed to support the floor joists above are load-bearing.

Addition:
When houses settle, other walls can also become more or less load-bearing or stabilizing.
I agree with Purre that a structural engineer is probably the right way to go.

Hi.

I am renovating the kitchen and thereby tore down a wall to enlarge it. The kitchen is already purchased and everything is basically ready for guessing and lowered ceiling to set hutonit.

Previously, I fixed up the boy’s room on the upper floor (just laid flooring on existing vinyl and did some wide spackling) and was in there today and felt that the floor was a bit wobbly in the middle. If you stamp, it makes noise with the changing table and a shelf that is in there. I have begun to suspect that I tore down a partition wall that acted as a floor joist...the house is from the 1920s. What do I do now? I can't put a beam from the underside as I have already bought the kitchen and there is no way it will fit now...can I tear up the floor and anchor a new floor joist in the outer wall? Can I use blocking to reinforce the upper floor? Is it urgent or can it wait? Grateful for an answer...

I had more wobble than that. Four-meter long 145 joists without blocking. Tore up the floor, sawed all the joists in half and cast a concrete beam across. Also installed blocking.
Now it feels sturdy.
