FireGuard - Ceramic Flue Repair

Certified FireGuard Resurfacing – The Superior Choice for Chimney Flue Repair

At Chimney Bear, we take chimney safety and restoration to the next level as one of only two companies in Illinois certified to perform FireGuard Resurfacing.

The patented FireGuard ceramic system, certified by Guardian Fire Testing Laboratory, Inc. (ISO 17025), is the only industry-certified ceramic resurfacing and mortar joint repair system designed to restore damaged or defective clay flue liners with precision and durability.

Unlike traditional methods, FireGuard uses pinpoint vibration technology to penetrate tight mortar joints and fractures deeply, creating a solid, uniform ceramic coating that effectively seals and strengthens the chimney flue. Without this precision process, ceramics cannot fully penetrate or form a consistent, long-lasting bond.

Fun Fact: FireGuard’s top competitor, HeatShield, stole the proprietary formula from the inventor of FireGuard. However, they could not replicate the patented vibrating applicator, which is essential for deep penetration and uniform coverage. Because of this, the HeatShield method lacks durability and is more prone to failure, making FireGuard the superior and more reliable choice for long-lasting chimney resurfacing.

With a temperature rating of 3,205°F—the highest in the industry—FireGuard offers superior heat, acid, and water resistance, significantly reducing heat transfer and virtually eliminating gas seepage through flue liners. This advanced chimney resurfacing solution is suitable for any size or shape of flue, making it one of the most reliable and durable chimney repair methods available.
