Stack.

I was worried about the damp that has been creeping into the small bedroom. I thought the pointing was suspect and decided too check it out. BIG MISTAKE! I got up there, a flipping long way, and it was shot. I took down about a third of the stack as it was held together with black mortar, that was stinking and just dust with no cohesive qualities.

Cue me rushing to the builders merchants and getting sand, cement and buckets too do the work. I hope that this has resolved the matter and it wont get worse before winter sets in. Fingers crossed.
