To repair chimney interiors, one of two methods are used. The Joint Repair System is used for chimneys that only require repair of defective mortar joints. The Resurfacing System is used to repair mortar joints and other minor defects in tile lined flues.
With our (patent pending) Joint Repair system your chimney is fixed right, the first time.
First, a special foam applicator blade is custom made to fit your chimney. The applicator tool and blade are then plunged down your chimney and positioned below each gap or void.
The HeatShield® Cerfractory® Flue Sealant mixture is added. Each void in your flue is filled as HeatShield® mixture is extruded into the void by the tool. Your repaired void is then made smooth as the blade passes over the filled void as the tool is pulled upward.
Your repair is then immediately scanned with a specially designed video camera. The Chimney Sweeps of NE Tennessee technician then verifies that each gap or void has been properly repaired as it is immediately viewed on the cameras monitor.
