Water down the chimney
We had a long soaking rain event this weekend in MA. I took the opportunity to do a careful leak exam on the interior of our reno (dryed-in but interior walls are still open).
The first and second floor fireplaces, both attached to the same tall chimney, had water running down the interior of chimney into both fireplaces. There were also signs of water leaking through the brick into the interior. I’ve never experienced this before with other chimneys. The chimney may be 100 years old, but it was inspected and determined to be sound.
Question … is the water entering at the top of the chimney or is it blowing through the substantial length of brick/mortar extending above the roof? The former could be remedied with a chimney top damper? If water is leaking through the brick / mortar, that would seem to mean flue gases could as well.
