HeatShield® — The Chimney Liner Repair & Resurfacing Solution That Works Fast & Lasts For Decades

Are you dreaming of nights by the fireside? Is your chimney ready for those nights or is it time to schedule some repairs? Here at Firesafe Chimney Services, we want to make sure your fireside experience is as safe and as enjoyable as it can and should be, and that means your liner has to be in tip-top shape.

Terra cotta or clay tile chimney liners have been used for decades because of their affordability and effectiveness. But what we often find when inspecting these liners is that cracks are present, gaps have formed between tiles, and the surface has been damaged over time.

When we let our customers know that repairs must be made before they use their fireplaces again, we can see the panic. Maybe you’ve experienced it — you think that means an expensive, time-consuming, messy rebuild or the purchase of a brand new chimney liner is in your future. That’s likely not something you’ve budgeted for, and it can be especially frustrating when it’s just a single crack or a gap here and there.

Thankfully, there are other options with the HeatShield® system.

HeatShield® offers three different solutions to liner damage, but all three start with the cleaning and prepping of the flue. All three also involve the use of the HeatShield® Cerfractory Flue Sealant and a customized foam plug or applicator.

The Cerfractory Flue Sealant is a ceramic/refractory hybrid. It’s able to take the abuse of moisture, corrosive flue gases, and incredibly high heat (even temperatures exceeding 2900 degrees F). Not only does it meet NFPA and IRC codes, it exceeds them — and it’s approved for all fuels.

Here’s how HeatShield® works:

  • HeatShield® Joint Repair (The Sporadic Damage Solution) — For gaps between flue tiles here and there, the HeatShield® Joint Repair system is the solution. To repair the flue, we use the applicator blade to apply the Cerfractory Flue Sealant to gaps, voids, cracks, and other small areas that need to be sealed and filled. The applicator pushes the product into place and smooths over the surface.
  • HeatShield® Slip Casting (The Resurfacing Solution) — When the surface of the flue liner could use some repair all over, we use the Slip Casting or Resurfacing system. To make the repairs, we place the foam plug at the bottom of the flue, pour the Cerfractory Flue Sealant down into the flue, and pull the plug up from bottom to top. As the plug travels up the chimney, it pushes the sealant into any cracks, voids, gaps, and holes, and leaves behind a smooth, streamlined surface that’s free of openings and damage.
  • HeatShield® CeCure Sleeve (The Relining System) — If the flue needs a little added strength and structural support as well as repair, we’ll use the CeCure Sleeve option. We start by doing everything we do during the Resurfacing process, only once we’re done, we insert a CeCure Sleeve (which is made of ceramic and stainless steel mesh) down into the flue. Once in place, we repeat the resurfacing process, sealing the sleeve in between two layers of Cerfractory Flue Sealant.

After we’ve repaired, resurfaced, or relined your flue, we’ll use our video scanning equipment to look at the interior and make sure every damaged area is properly sealed and repaired. We’ll show you the before and after photos/video so you can see for yourself just how amazing HeatShield® is!
