I was stripping wallpaper and found that a section of plaster came loose under the bay window. I removed what was loose and it has revealed that the brick underneath is loose too. I haven't removed more plaster, but should I? Should I just get some (lime) mortar and try to fix it back in place, or should I be removing more plaster to check out the surrounding bricks/getting someone more knowledgeable to investigate? The house is circa 1910.
Thank you
