I am looking at re-opening my old fire place and have seeked professional installers. I was advised by the install to insert a 6x6" hole in the place the original fire place opening was and get a chimney sweep around to ensure the flue was clean and clear.<br><br>I've created the hole and can see into the original fireplace cavity, however it is particularly filled with what looks like rubble/bricks/pourd concrete and 3 dead birds. <br><br>Also there seems to be a hole in the back of the cavity wall, lower right side and I can see what appears to be a metal structure of some sort. Could this be the rear of next doors fire place?<br><br>Even though this rubble seems to have blocked the flue, smoke is still drawn into the hole.<br><br>I've concluded this rubble must have fallen from above taken the birds down with it and upon impact on the bottom of the fireplace must have ruptured the cavity wall?<br><br>See attached images.<br><br>Has anyone come across this before and are able to advise.
