"which floors are you meaning with solid? ground floor concrete is no problem. it's if the upstairs floor is conctrete, that you have problems."
Good question, honestly I will need to double check if both the ground floor and first floor are solid (concrete). I've just been reading around that most of the council houses from the 60s used solid floors.
I just realised that I read "If you first floor is solid construction you can't put in recessed lighting without a drop ceiling." as ground floor - so I'll need to double check up on the first floor
The property is out in Haydock ( a couple miles north of NewtonLeWillows) , is that out of your patch?
