Hi there handy, clever people! My ceiling had a leak and now part is sagging at the join and coming unstuck in my living room. Also think my 85 year old home is sagging so problems in front bedroom in ceiling, also had massive construction on street digging 6 mtr deep huge storm hole drains which created subsidence. Also the Fix ideas please?
I'm a novice so need step by step help



.., or should I get a professional? Thanks!
