If you have rising damp symptoms in particular you will need an invasive damp survey. This means some amount of opening up will be necessary to locate potential physical damp proof courses, and eliminate any bridging of the damp proof course. Drilling and removing Plaster/mortar samples for further analysis (BRE DIGEST 245, plenty of info on the website about this). The British Standard
BS 6576,
also explains all the potential damp issues that need to be eliminated before coming to a conclusion, along with as a minimum, carbide meter tests, or better still gravimetric analysis. These tests can help differentiate between different causes of rising damp symptons, which a damp meter can't. Has your surveyor carried out such tests? Many damp experts will not offer invasive surveys. This is because it will add considerable time to the survey, and also time and expense with the analysis. Some don't have suitable equipment either. Have you been told by your surveyor to have a non invasive damp survey? We provide surveys for the below issues. Rising damp symptoms cause

Please note we don't offer free surveys. To get a price for the survey you require, you will need to speak to Ross Charters our surveyor, and go though your issues. From there depending on whats likely to be needed costs can be given. Further info can be found on the website on the types of surveys we offer along with images of issues.
