You should ask a builder or plasterer to fix it but first ask them if they know about ammonium sulphate contamination before they do any work , this is the cause of the problem , if they don't know about this , get a damp proofing company and ask the same question until you find a knowlageble person , you could waste plenty of money on not fixing it !
Hi Kirsty, I would always say roofer, because it sounds like your chimney breast needs pointing or flashing or capping! and although a builder is capable of doing this type of job, they have to have a good head for heights, and are able to work under the stress of working at height. and don't become more focused on their safety instead of doing a good job!
