A Coating Alternative to Relining
A Cost Effective Alternative to Relining When homeowners are faced with a damaged or deteriorating chimney flue, the traditional solution has often been a full chimney relining. While effective, relining can be expensive, labor-intensive, and sometimes more invasive than necessary. For chimney sweeps looking to offer their customers a reliable and cost-effective alternative, ceramic coating systems provide an innovative solution. Why Consider Ceramic Coating Instead of Relining? Relining with stainless steel is a significant investment for homeowners, and while it remains the right choice in most cases, ceramic coatings can be a more budget-friendly alternative without sacrificing safety or performance. By sealing cracks and gaps, reinforcing the existing flue, and providing a smoother surface for improved draft, ceramic coatings extend the life of the chimney and help restore proper venting. They’re also versatile enough to be applied in a range of flue types and shapes, making them a flexible solution when a liner isn’t the best fit. Recommended Products: FireGuard & HeatShield At New England Chimney Supply, we recommend two well-established ceramic coating systems, FireGuard and HeatShield. Both have been widely used by sweeps across the country and are trusted for their durability and performance. The FireGuard System The FireGuard ceramic coating system was the first of its kind introduced in the United States back in 2003, and it remains one of the most advanced options available today. FireGuard is known for its durability, its rigorous certifications, and its innovative application method. Its patented vibration technology allows the ceramic material to penetrate deeply into problem areas, creating a strong, seamless surface that strengthens the chimney from within. In fact, FireGuard is the only system that combines vibration motors and custom foam applicators, giving sweeps a reliable way to achieve an exceptionally smooth and consistent finish. FireGuard has been certified and listed through Guardian Fire Testing Laboratory under UL standards, providing added assurance for both sweeps and homeowners. It also carries the highest temperature rating in the industry at just over 3,200 degrees, which means it’s built to endure the toughest chimney conditions. With its two-component ceramic formula, FireGuard achieves excellent bonding strength, ensuring a long-lasting repair. For homeowners, the lifetime transferrable warranty provides peace of mind, while for sweeps, the system’s proven track record and unique application process make it an attractive option to offer as a premium ceramic coating solution. The HeatShield System While FireGuard is recognized for its innovative application system and unmatched temperature rating, HeatShield brings a legacy of proven European technology with a focus on adaptable repair methods. The HeatShield Flue Sealant & Repair System offers another strong path for chimney restoration, particularly for clay tile and masonry flues. In suitable chimneys, HeatShield can be tailored to the situation: it can be applied just to fill missing or defective mortar joints, or it can be applied as a thin, continuous coating over the entire flue to repair cracks, seal gaps, and reinforce the interior walls. What sets HeatShield apart is its Cerfractory technology, a hybrid blend of ceramic and refractory materials first developed in Europe more than 30 years ago. This blend combines the strength of high-fired ceramic with the heat resistance of refractory cement, producing a durable seal that restores venting safety. By eliminating gaps, cracks, and spalling, HeatShield significantly reduces the dangers caused by chimney deterioration. HeatShield is also noteworthy for being eco-friendly, since it is made from recycled and naturally occurring materials, and it provides a less invasive, less costly alternative to full chimney rebuilding or tile removal. The system is thoroughly tested and exceeds industry standards: it is rated “Super-Duty” under ASTM testing.
