I wonder if you took temp readings of that area under the pipe (where the condensation is occurring) if that brick (for whatever reason) is colder than the bricks around it, where the condensation is not occurring.. It seems to me the bricks would need to be cold for condensation to form on them. Unless the moisture is coming directly thru the brick from outside. I think your first step to solving the problem is to see if possibly the bricks are just cold, causing condensation to form from moisture in the surrounding air. Where is the ground level directly on the other side of that area below the stove pipe? or is that an interior chimney?
Thank you. I will try to measure it. This red brick wall is an inside wall. Chimney then goes out into the external brick chimney that is white brick. I think the ground level is a little bit lower on the other side for the white brick chimney than the black spot is situated. So really it's not the problem lighting it up, it is more a problem of structural integrity whether condensation is not ruining my wall. I will wait for the proper conditions - it's usually when raining outside and my room is colder than the outside - and measure the temperatures.
By the same token, can anybody recommend a simple inexpensive IR T-meter?
