Heatshield Chimney Relining Image - Crofton MD - Clean Sweep AAA failing chimney liner puts your home in danger. When your chimney liner is cracked or flaking, or has developed gaps, heat and smoke can reach your home’s structure, putting your home at risk of a fire. Those weaknesses also can allow carbon monoxide to enter your home’s living spaces, putting your family and your pets in danger of carbon monoxide poisoning.

Replacing a chimney liner can be expensive. To rebuild a clay tile liner, the entire chimney has to be disassembled and rebuilt; stainless steel chimney liners are an option, but they can cause stress on the system while being installed.

Our certified chimney technicians are factory trained in the application of Heatshield and are experienced in relining many clay tile liners with this product. Our technicians can inspect your flue to see if Heatshield Cerfractory Flue Sealant is the best repair for your liner.

What is HeatShield Cerfractory Flue Sealant?

HeatShield Cerfractory Flue Sealant is a hybrid product that combines ceramic material and refractory cement. The ceramic makes gives HeatShield strength, while the refractory cement gives it the ability to handle the extreme heat from your fireplace.

How does HeatShield work?

HeatShield is a powder that’s mixed with water to create the pourable cerfractory material. An applicator is made to fit the inside of your flue and it is dropped down into your chimney. The material is poured down the chimney, and the applicator is pulled up to smooth the material into the cracks and grooves of your flue. It then hardens to a cement-like finish within your flue, creating the new flue liner.

When can HeatShield be used?

Over time, the heat of your fireplace, moisture from the atmosphere and the corrosive byproducts found in soot and smoke can erode the inside of a clay tile flue liner. The mortar joints between the tiles can crumble away, leaving gaps within your fireplace; the tiles can crack; or the faces of the tile can fall away, a problem referred to as “spalling.” HeatShield can be used to solve any of these chimney liner problems. Depending on the severity of the liner defects, HeatShield Cerfractory Flue Sealant can be used alone, or it can be combined with other HeatShield products to restore the integrity of your chimney liner.

How do can you be confident HeatShield will last?

After your chimney liner is restored with HeatShield Cerfractory Flue Sealant, your chimney technician will perform a digital inspection of your chimney’s interior, so you will be able to see the new liner that has been smoothed into place. HeatShield has been UL tested, in accordance with the standards of chimney liners. HeatShield Cerfractory Flue Sealant carries a 20-year manufacturer warranty.
