DON’T Install A Chimney Liner Until You Read This!

Chimney maintenance is an essential aspect of home ownership, ensuring the safety and efficiency of your fireplace or wood-burning stove. Installing a chimney liner is often recommended to improve the chimney’s performance and safety. However, traditional chimney liner installation can be a daunting and costly task, involving craftsmanship, precision, expensive parts, and a considerable amount of mess. In this blog post, we’ll delve into the challenges of traditional chimney liner installation and explore the advantages of a cleaner and more affordable alternative: Thermocrete.

The High Price Tag of Traditional Chimney Liner Installation

  1. Craftsmanship and Precision: Traditional chimney liner installation is no job for amateurs. It requires skilled craftsmanship and precision to ensure the liner fits snugly within the chimney, sealing any cracks or gaps that may allow toxic gases to escape into your home. Hiring experienced professionals can be expensive.

  2. Expensive Parts: The materials used in traditional chimney liner installation, such as stainless steel or aluminum liners, can be costly. Additionally, there are often additional components like connectors, caps, and insulation that add to the overall expense.

  3. Demolition and Cleanup: Installing a chimney liner typically involves breaking down and removing the existing flue tiles or damaged liner. This process can be messy, involving dust and debris that require extensive cleanup.

  4. Time-Consuming: Depending on the complexity of the project, traditional chimney liner installation can take more than a day to complete. This extended timeline can disrupt your daily routine and lead to increased labor costs.

Thermocrete Application: A Cleaner, Less Expensive Alternative

Thermocrete is a revolutionary solution to the challenges of traditional chimney liner installation. It’s a ceramic flue lining system that offers several advantages:

  1. Minimal Mess: Thermocrete is mixed on-site and pumped directly into the chimney, eliminating the need for demolition and reducing dust and debris. This results in a cleaner installation process with minimal disruption to your home.

  2. Cost-Effective: While the initial cost of Thermocrete may be comparable to traditional stainless steel liners, the overall cost is often lower due to reduced labor and cleanup expenses. Moreover, Thermocrete can extend the life of your chimney, reducing the need for frequent relining.

  3. Precision Application: Thermocrete is pumped into the chimney and adheres to the existing structure, creating a seamless and airtight liner. This ensures the utmost safety and efficiency, much like traditional liners.

  4. Speedy Installation: Thermocrete installation is typically completed in a single day, minimizing inconvenience and labor costs.

HeatShield® is a specially formulated “Cerfractory®” sealant material that restores the integrity of your chimney’s flue to vent hazardous flue gases from your home. It eliminates the dangers in your chimney caused by gaps, cracks, and spalling for years to come. By using either the Repair System or the CeCure® Sleeve Relining System (depending on the defects found) your chimney will be restored to its original peak level of safety and efficiency.

Chimney Interior Flue Repair

To repair chimney interiors, one of three methods are used. The Joint Repair System is used for chimneys that only require repair of defective mortar joints. The Resurfacing System is used to repair mortar joints and other minor defects in tile lined flues. In chimneys with more serious defects or unlined chimneys, HeatShield® can be used with the CeCure® Sleeve Relining System.

Who Can Provide Thermocrete Application?

Thermocrete Ceramic Flue Liner can only be installed by a factory-trained technician. All installers are required to attend a comprehensive Thermocrete training program. After successfully completing the training, they receive official certification, assuring you that they are an authorized Thermocrete installer. Duct X – Air Duct Cleaning & Chimney Sweep is an authorized installer of Thermocrete in the state of Texas.


Installing a chimney liner is a crucial investment in the safety and performance of your chimney. However, traditional liner installation can be both costly and messy, requiring skilled craftsmanship and multiple days of work.

Before embarking on your chimney liner project, it’s essential to assess your specific needs and budget.

Ultimately, a well-maintained chimney will provide you with warmth, comfort, and peace of mind for years to come.
