Hello,
I have recently had to have my entire bathroom replaced due to water damage from leak including the floor (changed floor boards to 75mm ply due water damage). I was told that joists were ok, although I now have reason to suspect that they could do with strengthening.
If possible I'd like to do this by going through the ceiling below (i.e. pulling it down) because I don't want to take my only bathroom out of action (and pulling up floor tiles is a nightmare). My concern is that by going from underneath I won't be able to screw the floor boards to the sister joists very easily, which leaves me wondering if glueing the top of the joist to the floor from under neath and using right angled brackets that will allow me to screw upwards will be good enough to re-secure the floor (if it has, I suspect, come slightly away from the joists). I would secure the sister joists to the original either with screws or bolts.
Does this sound like it would work? Are there better ways of doing this?
Thanks.
P.S. The joists are not rotten, I'm just concerned that the plumber has weakened them by cutting too many notches out of them.
