Approved Industries, the leading manufacturer of advanced ceramic coatings and thermal protective systems, provides chimney professionals with robust, cost-effective solutions for restoring damaged liners. Flue liners, vital for venting combustion byproducts, are susceptible to cracking due to age, heat exposure, and even chimney fires. Thermocrete® is a durable, long-lasting alternative to more expensive liner repairs and relining. Its proprietary heat-resistant ceramic coating effectively seals cracks in flue liners, resulting in a smooth, uniform surface for safer and more efficient venting.
What Happens When the Chimney Liner Is Damaged?
A damaged chimney liner is a big problem that poses serious fire, health, and safety hazards, including:
- Carbon Monoxide Exposure: Liner cracks allow toxic carbon monoxide exhaust to seep into your home. Exposure to this odorless, colorless gas can cause carbon monoxide poisoning. Symptoms include headaches, nausea, and drowsiness, followed by death.
- Fire Hazards: The intense heat in the flue can escape through cracks in a damaged liner, igniting nearby combustible materials, such as the wood chimney chase, attic, or roof deck. When this occurs, the fire can quickly spread from the chimney to the rest of the house.
- Reduced Efficiency: A compromised liner hinders proper draft, leading to inefficient combustion and increased fuel consumption. It also produces more creosote and pollution, increasing fire risk and reducing indoor air quality.
- Structural Damage: When using a fireplace or stove in a chimney with a damaged liner, moisture and corrosive byproducts can further weaken the interior masonry walls, resulting in deterioration and costly repairs.
Common Signs of Liner Damage:
Recognizing the signs of a failing liner is crucial for timely intervention. Look for:
- Cracked or missing flue tiles.
- Debris in the fireplace or at the base of the chimney.
- White, powdery deposits (efflorescence) on the exterior of the chimney.
- Damaged or deteriorated mortar joints.
- A smoky or musty odor in the home.
- Visible cracks in the crown or chimney structure.
How to Repair Damaged Liners with Thermocrete®:
Approved Industries’ Thermocrete® offers a revolutionary approach to liner repair, bypassing the need for expensive and disruptive complete liner replacement. A factory-trained chimney professional uses a specialized spray applicator. The applicator is lowered into the flue, applying a consistent, even layer of Thermocrete® ceramic coating. The coating penetrates and seals cracks, gaps, and joints, creating a smooth, durable, airtight, and heat-resistant surface. This method significantly reduces repair time compared to traditional relining, providing a quick and effective solution.
Thermocrete® gives chimney sweep professionals the ultimate cost-effective solution for relining residential and commercial flues, with fast application, easy maintenance, and a limited lifetime warranty.
