We’ve just bought a granite cottage in Ashton near Helston. Some of the walls inside are pointed with just concrete ( recently I think as there’s a heavy smell of concrete in the house). We want to replace it with proper lime based pointing but there seems to be rather a lot of pointing around the stone and I wondered what the implications of that are. I’m also wondering if we could do your course and have a go ourselves or employ an expert like you to do the work. I have some pictures that I could send if it would your valued opinion please?
