Revolutionary Chimney Repair HeatShield® Restores Your Chimney

Chimneys were never designed to be taken apart and then put back together. However, that’s exactly what we used to do when installing a new stainless steel flue liner to meet the manufacturers requirements. That’s why we recommend the #1 preferred method of chimney reling restoration, HeatShield®.

Why You Should Consider a Revolutionary Lining Repair Method

  • Chimneys systems are constructed with intentional adherence to mathematical sizing. The HeatShield® Method does not compromise this and there is no requirement for downsizing.
  • There is no demolition on or in your home.
  • Similar methods of repair have been made in Europe for over 30 years.
  • All American Chimney Service has been vetted and trained to meet strict standards to be approved for HeatShield® application.

HeatShield® is formulated specially as a “Cerfractory®” sealant that helps restore the integrity of a chimney flue. Your chimney will vent hazardous gases from your home without the danger of gas and debris venting out the gaps and cracks, as well as preventing spalling for years to come.

The smoke chamber will most likely need repair as well during the process due to the same wear and tear found in the flue. By using either the Repair System or the CeCure® Sleeve Relining System (depending on the defects found) your chimney will be restored to its original peak level of safety and efficiency.

Joint Repair

We use one of two methods of repair when the joints of the ceramic flue tiles come out of alignment.The first is a Joint Repair System used for chimneys that simply requires the repair of defective mortar joints. These are the joints that hold the flue tile together. The second is called the Resurfacing System and is used when mortar joints, as well as additional minor defects in tile lined flues, need repaired. With Heatshield® (patent pending) Joint Repair system, your chimney is fixed right the first time.

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 mortar joint. The HeatShield® Cerfractory® Flue Sealant mixture is added. Each defective mortar joint in your flue is filled as HeatShield® mixture is extruded into the gap by the tool. Your repaired joint is then made smooth as the blade passes over the filled void as the tool is pulled upward. The repair is immediately looked at with a specially designed video camera that is attached to the bottom of the applicator tool. Our professional HeatShield® installers will verify that each gap or void has been properly repaired as it is immediately viewed on the camera's monitor.

Resurfacing System

The Resurfacing System is used when a chimney has a cracked or spalled flue liner that is otherwise functional and sound. With this system, a coating is applied over the entire flue and a camera is used to verify the repairs. Resurfacing the interior is the perfect way to restore integrity to the entire flue liner. A custom-made foam applicator plug is lowered to the bottom of the flue and attached to a winch that is placed on top of the chimney. A “tie coat” material is poured into the flue and applied to the walls as the plug is pulled upward by the winch. The “tie coat” cleans any remaining dust in your flue and acts as a primer for the HeatShield® Cerfractory® Flue Sealant. Once the tie coat dries, the material is poured again into the flue and applied onto the inner wall at a thickness of about ¼”. The foam plug makes sure the material is smooth as it is pulled upward by the winch. This method is known as “slip casting” or “slip cast extrusion”. Your professional HeatShield® Installer then verifies that your newly-restored chimney is completely sealed and smoke-tight by video scanning your completed repair.
