Replacing joists / installing lintel

[danr86]

Some of the upstairs joists in the kitchen below the third bedroom are rotten and some have bowed. Some of the joists are sitting on a wooden plate which has rotted and sits between the layers of bricks. I need to replace part of the plate but was it the best way of doing it?

Should I just remove all the joists and redo the entire bedroom floor? If so how do I do this - anchor bolt a new plate to the brick work and use jiffy hangers to hang new joists - if so what size plate / joists / anchor bolts / spacing etc.

Another problem issue is on opposite side of the kitchen - it seems the previous had double glazing installed but there is only a wooden lintel above the window frame. Above this there is the wooden plate which spans the length of the wall and supports the joists. Also above this is a stud wall which is further causing a large dip in the upstairs floor? How can I fix this? Should I rent some acrows, remove the joists, jack up the plate and then insert a concrete lintel?

Lastly it seems that the wall of the extension has come away from the rear of the house? Should I be concerned by this and what can I do to fix it - will sand and cementing over it be sufficient? I'm intending to have a boiler installed on that wall.

It may not be as rotten as you think. If it is oak, and it looks it to me, it can have enormous strength even when the outer faces have rotted away badly.
But the best advice I can give would be to have a professional person visit before you start propping up the floor and removing structural timbers.

You will need to support it correctly before you remove anything.

Also,

The crack needs to be investigated.

Could be the foundations that have some movment.

That's why I said he need's a professional to investigate before he does anything.

Surveyor said when I purchased the property that
"Although evidence of previous movement was apparent typical of a property of this age, we noted no evidence of recent significant movement to suggest problems at foundation level."
