Tuck pointing 101

So as I type, there are two wonderful people working on replacing the mortar in the really bad wall of our house. I can not describe how relieved I am, just to have someone working on it. They should be done Monday. YAY! They are grinding out the old, well, sand right now. Who knew? Well, besides people who actually research these things before they throw themselves headlong into owning a pretty old house. (refer to the end of the very first post).
