Repointing or rebuilding a chimney top
Most chimneys I look at need their joints and flashing fixed, not a rebuild, because that's where the wear usually is. I lean toward repair when the brick is sound and the chimney stands straight. When bricks are cracking, flaking or loose near the top, patching just buys time, and taking the top down to good brick and laying it back up is the better call. I'll tell you which one yours needs, and why.
