The crown was in disrepair and the flue liner was cracked. Crowns with cracks can leak water which can get into your home. Water also can leak behind the flue tiles causing separation and potential protruding mortar joints. When mortar joints protrude, there is potential to fall out which can also cause flue tiles to collapse allowing for buildup behind it. If your chimney presents with this issue, when we come sweep your chimney, there is no guarantee to get the debris in between this uneven surface.
