I had a look at said cracks this afternoon when I went round to speak to them – they are all hairline cracks. In my opinion caulk would do the job fine – its only cosmetic plaster cracking not the actual bricks underneath.
As has been said if it was settlement you would expect some new cracking in my house – which there is none – it may be due to vibration I will concede.
I really want to make good this for them – I just feel that they have gone to an expensive tradesperson – told them they are not paying we are and he has gone to town.
Everyperson who has seen the cracking i.e. my builder (not impartial i realise) and building control feel that the price quoted is ridiculous.
Hopefully our tradesperson can come up with a more reasonable quote – if he comes back the same then I guess we have to suck it up.
