Your chimney is designed to last, but many factors can cause it to become worn and damaged. In some cases, your chimney can require drastic repairs and even a rebuild. When damage is caught in time, it can be repaired simply, with industrial solutions that have been tested and designed for just that.

All About HeatShield Image - Boston MA - Billy Sweet Chimney SweepHeatShield® Cerfractory® Technology

HeatShield® combines the strength of a high fired ceramic with the heat resistance of high temperature refractory cement. This technology is long-lasting, heat resistant, and versatile. Thus, it can repair in a few ways. The material is a powder that is mixed with tap water before the job is done. Therefore, HeatShield® Cerfractory® sealant is not wasted, and costs remain low. Since it’s creation, chimney experts have been using HeatShield® to restore chimneys, using one of three systems of repair:

  1. Joint Repair System
    This system repairs joints correctly, strengthening your chimney and restoring it to full function. When there are gaps between flue tiles, a foam applicator blade is fit for your chimney and positioned below each gap. The HeatShield® mixture is placed into the gaps by the tool and the flue is smoothed as the tool moves upward.
  2. Resurfacing System
    What if the chimney is sound, but has cracks, spalling, and gaps in the flue? The resurfacing system restores the flue from top to bottom. The custom foam applicator is used, as it is in the joint repair. However, this time it is placed at the bottom of the flue, and hoisted upward with a wench. This tool applies a “tie coat” material to the flue walls, which cleans and primes the flue walls. After this coat dries, HeatShield® is applied, with a thickness of 1/4″ again using the foam applicator/wench system. This process is completed with a video scan to ensure the flue is restored, smoke-tight, and smooth.
  3. CeCure® Sleeve Relining System
    Much like the resurfacing system, this system requires a custom foam applicator/wench that applies HeatShield® Cerfractory® Flue Sealant. Next a CeCure® Sleeve is lowered into the chimney and attached to the top. This sleeve is a high-density, low profile, ceramic insulation sleeve, reinforced with stainless steel fabric. It is pressed firmly into place when the foam applicator tool is pulled back down the flue. Afterwards, the job is completed when a coat of HeatShield® Cerfractory® Flue Sealant is applied on top of the sleeve. This job is checked with a video scan, and a complete relining system. This restores a damaged liner, or lines an un-lined flue. This system is appropriate for all fuel types and is long lasting.
