Jim Baird Posted March 26, 2019 Report Share Posted March 26, 2019 (edited) Here is a fun problem. Where did these sand deposits come from both on the front and the side of a massive chimney column of a 70's brick ranch? The column rises from the ground up through it all, has a rectangular and a square clay flue, one for a gas furnace vent, another for a fireplace that was fitted later with gaslogs. Column up top lacks a cricket, as modern codes would require, but I could see no roof leaking around the column perimeter despite the really sloppy flashing. House has been unoccupied for an unknown time, no disclosure available. My thinking is that the sheer mass of this column's faces has resulted, in a wetter than average year, in moisture migration towards the ground, that pushed this sand out of the mortar joints.
