enter image description hereBought this home over the summer. I recently rebuilt the exhaust flu for my boiler because it was deteriorating from water damage. The round hole in the basement foundation wall that the boiler exhaust exits through has water making its way from underneath the chimney. You can see in the pictures what the water has done to the exhaust over the years. When I removed the old exhaust it happened to be pouring outside and I was able to see exactly where the water was coming from (see the 2 red arrows). It appears that water is coming from underneath the base of chimney and squeezing itself between the clay chimney liner and whatever that black material is at the base of the chimney. It drips down the wall onto the floor. I was told to seal up the section where the water was entering the base with cement which I did about month ago. There have been several hard downpours since then and I havent seen any water leaking until today.
I havent been on the roof to check the chimney for cracks on top but when I look into the base of the chimney from the basement, the chimney walls are always dry and the water is only coming from under the chimney base. So I have to assume the top of the chimney is fine. My gutters are clean and the gutter drain is far away from the chimeny base.
What can I do here myself before calling in a professional. I was thinking about digging out all the dirt around the base of the chimeny to check for cracks but I dont know if Im wasting my time. [![enter image description here]]
