I removed bathroom/bedroom partition and exposed the floorboards to reveal rot (picture upload not working). At least top 50mm of 165mm joist is completely rotten. It is a 1978 Wimpey end terrace with joists running between party wall and end wall. The rot is adjacent to the end wall and is obviously the result of a leaking shower.
If I lift the floorboards and take down the sagging ceiling I can get good access. Can I DIY? I'm thinking an Acro supporting the mid point of the joist, support the rotten end by tying to a 2x4 stud across adjacent joists. Cut the joist 600mm (2') from visible rot (about 1.5m from the end). Splice a new section with joist splice plates.
If there are no noggins, should I raise the Acro while splicing the joist to pre-tension the joint?
Where can I get splice plates? SabreFix SP82 look suitable but can't find a supplier.
