Ask Us About Restoring Your Chimney Liner With HeatShield®

As fires burn in your firebox, gases are created that contain harmful byproducts, like soot, water vapors, carbon monoxide, and other corrosive or harmful chemicals. Now, your chimney liner is put in place to keep these fumes from damaging your system or entering your home, but sometimes liners break down, especially if they weren’t built correctly from the start.

What results is cracked flue tiles and spalling, both of which put your home and system at greater risk and increase your chances of experiencing a hazardous event, like a chimney fire, house fire, or carbon monoxide leak.

Fortunately, our techs can restore your liner with HeatShield®. HeatShield® is a specially formulated sealant that can restore your liner without forcing you to go through an expensive relining process. It’s reliable, effective, and has been used by certified sweeps in the industry for years. Rest assured, this is one product that will stand the test of time.

How Can Damages to My Liner Affect Me?

What happens if your liner isn’t repaired and simply continues to face damage? Well, you’ll be more likely to experience…

  • Fire Hazards: One of the biggest reasons liners are needed is to prevent the heat and flames from your firebox from escaping into your home. Even the smallest defects can put you and your system at risk and trigger more damage down the line. This is definitely an area you don’t want to neglect.
  • Gas Leaks: Because your system produces harmful gases, ensuring your family is protected from these gases is imperative. If openings and imperfections are present in your chimney liner, harmful fumes will have ample opportunity to enter your household, putting the health of those within it at risk.
  • Lowered Efficiency: Chimney liners need to be tight and damage-free to send smoke and fumes safely up the chimney. If cracking, gaps, or holes are present, you can bet that efficiency will be lowered significantly, and the system will consistently perform poorly.

What Are My Options With HeatShield®?

With HeatShield®, we offer a Joint Repair System if you simply need some gaps or voids filled, a Resurfacing System for flues that are facing more significant cracking or spalling, and a CeCure® Sleeve Relining System for systems that are unlined or so damaged that they need an entirely new liner applied.
