Hi John

Thats it! Youve made up my mind that I have to rip down the old plaster and
lathe to get at the underside of the stairs.

Do you forsee any problem with doing this?

I think these days the fire regs require plasterboard under the wooden
stairs. My last house had it, current 1930s house does not.
I'm sure no-one will miss it. People tramping up and down the stairs
may appear to make more noise without it. But to fix stairs properly
you have to get underneath. I need to fix my stairs soon ...
