Another Victorian House question. Don’t know how long-standing it is as we’ve just moved in, but some pretty big sag in the floor (pictured). Spirit level leaves huge gap underneath. Second floor. Is this likely structurally sound?
Has there been any historic knocking through and lintelling over in the ground floor below?
Any cracks in internal walls or external walls?
Do all door & window heads look level and easily open?
Your joists are running from left to right of the pics.
Floor boards have been lifted previously - for whatever purpose,
Was this floor mentioned in the mortgage or private surveys?
Are we talking about one bedroom only ie Bedroom 2?
Does the sag extend across the room - does it show anywhere else on the first floor.
Is the knock-thro to the kitchen below this floor?
Use a long level or a level and a long straight edge to check the level of the knock-thro lintel.
But first check your bubble level for accuracy.
You could remove the board(s) at where you think a lintel might be, and have a look at whats there?
Are any or all the chimney breasts still intact from GF to stack?
Right, not got the tools to cut through the floorboards proper so removed as much as I can next to the dip. The previous work seems to have been cabling. Joist itself seems level over where the dipped boards meet. Boards are both 2cm. Floor sags in one direction a little on the left side of the room, and a little in the other on the right. And there seems to be some concrete further down (floor is highest there). Also (last two pics) added what the joist near the sag look like going in the other direction. I’m stumped!There might be two sets of long joists that meet over thin air, and have been nailed together - something I've seen. Or too big notching or boring for pipes. Or pianos or safes. There are quite a few possibilities for sagging joists.
Whatever, please post pics of whatever you expose even if it looks fine.
By and large, with care & experience fixing the floor back to level is no great sweat.

Haha, sorry Woody! Did you see rotten joist ends? Sorry, am inexperienced! The joists running across in the pictures run respectively into an internal wall and a shared terrace wall.Jesus, what a monster thread.
Joist ends rotten?
Thanks for all that effort.
Well done for laughing off that arrogant, cant bear to be challenged bit of sad sack.
Pic 395 shows what's probably the concrete hearth for the chimney breast.
The joisting around the hearth typically supports itself by Trimming - check google for trimming diagrams.
The joists are not supported by the c/breast itself.
The hearth is supported by the trimming, & sometimes is semi-supported by the c/b fireplace.
If you lift more boards you should expose the trimming.
Pics under the boards will show the trimmer if its there or will show joists going into the hearth.
Is the ceiling below the hearth flat & level looking?
Some of the characters who come on here simply want to be big shots, (on a DIY site?) - they have nothing else in their lives - they want to make points to the detriment of DIY'ers questions.
No need for fixing the floor very soon - perhaps its been like that for years.
But when the cause is determined you will be able to bite the bullet in your own time.
Any news on the hearth exposure issue?
