I wouldn't have thought that 20mm off a single joist would make a lot
of differerence.

Depends on size of the timber, length of the timber, live load, dead load
etc, and generally you would be right - but what about the unexpected?

But the one the one question that has yet to be asked - is why has a
(presumably old) joist bowed nearly one inch upwards for no apparent reason
(in a presumably) short time. Surely that reason has to be found before any
remedial works can be suggested?

Just out of curiosity though, how can you base your decision on a job that
you have never seen and with the minimal information given - you and Dennis
must have second-sight Harry
