Hi there! I recently used my new DJI Spark drone to visually inspect my chimney from above (picture attached). As one can see, there appear to be gaps / holes to the side of the smoke stacks (if that is the correct term here). I wonder if I need to have those repaired (and how) or if installing a chimney cap would suffice to prevent rain from entering my chimney.
In general, should I worry about water entering? None of my neighbors appear to have chimney caps, so maybe I'm overthinking it?
Thanks!
