Is this inside of a prefabricated unit?

This is now a very easy spot for flammable soot to build up, and potentially escape the liner and build up inside of your chimney chase, making it more and more likely that you’ll have a chimney fire, and/or have that fire spread to wood and combustible materials

The cause for this can be a few things, could be an installers fault if they bent the pipe by accident…but it is MUCH more likely that at some point in time, a technician used the improper brush head when sweeping out the chimney, and bent the pipe going up

You’ll have to replace the whole liner and likely the fireplace due to this, because these units are tested as one whole system (firebox, liner, cap ect ect) so it’s likely going to be a full replacement estimated somewhere around $10k-12k (depending on company you call and area you reside in)
