How do I raise Joists???

[Deadstar]

Hi all, I've bought a 1904 detached place which had slipped at the front and was underpinned - Had the structural engineer go over the place and its fine. I am however left with all the first floor rooms slopping towards the front of the property. As I intend to replace all the ceilings and replaster all the walls, can i use use bottle jacks and acro's to lift the joists then pack underneath them? And just to make it interesting, the front room ground floor rooms are suspended - does this effect anything in terms of lifting the joist?
Thanks

Any help advice tips etc much appreciated.

Not sure I understand this but

The joists will probably go into the walls , the skirting and the plaster in the rooms above would foul . I would remove the old fllorboards and pack them up and lay some 18mm or 20 mm flooring

remove flooring and level joists with strips of wood nailed to the top start at the highest point in the room then relay floor with p5 boards nailed and glued

See the DIY Doctor projects section, levelling floor joists.

maybe the rooms you're talkin' about are built on a porch foundation, that would be the reason for the pitch, so any water on an open porch would drain away from the foundation./ ext. walls.if that's not the case , it might be an extention with a bad foundation. if it was done in a slab , look outside where the structure starts and look for cracks where they married the foundation, [ this is also the case with a block or poured foundation.] you should check the ceiling joists, if they arre level, [or much less than the floor] then it was probably built on a porch structure. [this is better than a poor foundation.!] if not , YOU WILL NEED START WITH A REAL FOUNDATION! it is very important. if you cheap out on it, it WILL cost you sooner than you think. but it's still not that bad if you have the $$ . [ i'm not trying to sell you, i do fine home improvements on F.I , NY, ONLY....] so , DO NOT do it , unless the foundation is sound. if it is , you could rip out the flooring [ down to the joists] and sister them up level, new subfloof, ten flooring. i hope i helped.
