Can't really give you a figure, wolfie.
There will be a charge for materials *and* labour............
Will all or only 'some' plaster need to come off ?
The roof and wall (a dormer) have been leaking for about 3 years - kept getting it patched up and it kept leaking. Got it done properly this time and I feel confident enough to 'think' about plastering. The wall is a mess and will need to be de-plastered I think.
It is right beside my bed and I have been sleeping in the spare bedroom on a mattress on the floor for months.
This year has been bad for things going wrong in the house and I really hope things improve before I have to raid the kittie's piggy bank.
It will take quite a while to dry out completely. It's been going on for so long that the masonry will be saturated. If you do go for knocking off, then have it done as soon as possible to let the wall dry out naturally. As Jack says, I can't be specific, keeping an eye on the colour of the masonry will give a good indication as to how it's going.
Could you post a couple of pics?......... with maybe a close-up?
Post them on my FB wall?
some of it already has. at times it has been very very wet
Q>> Is it plaster directly onto brick/stone?
i didn't know that there was a difference between a brick and a stone
Q>> If it's just damp, what makes you suspect that it may need to be re-plastered?
it was more than damp. prior to 13 December 2008 it was damp. after that is was wet. Anyway I have an asthmatic pussy cat I don't need damp in my house. The poor wee lad would get sick. ;-)
I think the builder was meaning 'masonry' rather than a specific type.
This will need to dry out before it can receive a new plaster finish; this may be a two-coat finish, which will need 'in-between' drying time.......hence a couple of days from your plasterer at whatever daily rate he charges.
