Our home was built in 1896. It has 2 coal burning fireplaces which we have never used and probably haven't been used for many years. Noticed dirty water leaking out of basement clean out door of the chimney. Opened the door and found it is completely impacted with mud! I cleaned some of it out but there is still a bunch left. There also looks to be tree roots in there too 😬 Has anybody seen anything like this? I do have a chimney guy coming to look at it , but was curious if anyone else has had this happen and what kind of fix it requires.
