Can anyone help? We have a very uneven old house and one side of the ceiling is at least 3in lower than the other. (This is historic movement and should have stopped now). I think we should plasterboard and skim, but I'm unsure how to fix the plasterboard.
So far... I have this info
1. Use a laser level to find the correct level of the ceiling.
2. Find the joists
3. Screw plasterboard to joists
The problem is how to I lower the one side of the ceiling by 3in and fix it without removing the orginal ceiling and keep the weight down to a minimum? (Weight issue is why we haven't used bonding to level the ceiling.) Are there ultra lightweight plasterboards I can use?
All advice would be really useful.
