What exactly is HeatShield®?

HeatShield® is a ceramic refractory sealant which is used to fill in any cracks and gaps in your clay chimney liner. HeatShield® restores your old liner by creating a smooth, even, and air-tight surface. This formula has been tested extensively to guarantee its resistance to moisture and other damage from the corrosive by-products of combustion. Trained in the application of HeatShield®, the certified chimney technicians at Winston’s Chimney Service are experienced in relining all sorts of clay tile liners with this product.

What are the different types of HeatShield®?

Joint Repair

If your chimney liner is only suffering from damaged and deteriorated joints, Winston’s Chimney Service uses this type of HeatShield®. Our certified chimney technicians will apply it by using a custom-fitted applicator which strengthens the joints of your clay tile liner.


If your clay chimney liner is cracked, we can resurface the entire liner with this type of HeatShield®. After cleaning and priming your liner, the expert technicians from Winston’s Chimney Service will apply the sealant down the length of your chimney with the custom-fitted applicator.


When your clay tile chimney liner has suffered from damage that is beyond simply repairing, we can completely reline your flue with the HeatShield® CeCure Sleeve relining system. Involving a custom-designed ceramic and stainless steel sleeve, our chimney technicians will install this sleeve and reinforce with two surrounding layers of the HeatShield® ceramic refractory sealant. If your chimney has no liner, we can also use this type of HeatShield® to provide you with a high-quality functioning liner.
