I've chizeled out the parts of the chimney that blocked my repairs and added another board to block the hole. Also caulked around the edges, but im not sure i got everything i should. Forgot to bring my phone, so no pics. Will take some pics next time we go to the house.
While i hate heights, going up the ladder is getting easier for me. It's just the looking down part that ties my nuts in a knot.
Once/if we get a new dumpster is when i'll be tearing out the molded wall/s and temporarily replacing them with plywood
