Hi.
I have taken on a pretty challenging renovation project of a victorian end terrace. The ceiling if flexing in the 2nd bedroom (approx size 12'x9'). The flexing is definitely the ceiling joists and they are very small, I would say they are less than 3"x2".
I think I will ultimately need to underboard the ceiling but can't go to the expense of tearing the old ceiling down and also replacing all the joists.
I am considering propping the ceiling in the middle to lift and support it and then adding additional support to hold it up. What options do I have to add support?
Ideas I had some up with were:
1. Bolting 4"x2" to the side of the current joists.
2. Running some 4"x2" beams across the top of the current joists (supporting properly at ends) and tieing the old beams to these cross beams.
3. dropping some ties down from the main roof joist (don't know what it's called but it's very thick) which runs across the roof at about 18" above the ceiling joists.
Any preferences or other suggestions?
Is it acceptable to underboard with 9.5mm plasterboard to keep weight down and make it easier to manhandle?
