HeatShield Can Repair, Resurface, or Reline

Through the years, you will need repairs for your chimney and fireplace for it to continue working safely and efficiently. You might need a new liner, repairs, or resurfacing. These suggestions might sound scary to a lot of homeowners. However, at Black Moose Chimney & Stove, we try to give our customers the safest and most efficient chimney systems at the best value. That’s why we trust HeatShield for resurfacing, relining, and repairs.


HeatShield is a cerfractory technology that combines the heat resistance of refractory materials with the long-lasting strength of ceramic. It is factory tested and found compliant in performance tests and against high heat. HeatShield lining systems are also as durable and long-lasting as a stainless steel liner, while being a fraction of the cost. Using HeatShield Cerfractory sealant, we can repair joints, resurface a flue completely, or even install a liner system using a CeCure® Sleeve.

Joint and Liner Repair

In order to apply cerfractory sealant into gaps and cracks, we first install a custom-fitted foam applicator blade into the system. This is positioned below the damaged portion of liner. Once we mix the product and place it in the applicator, the foam applicator blade is pulled upward using a winch system at the top of the chimney. While the blade is being pulled upward, it pushes the product into gaps and voids, and the blade smooths it over the surface.


When your chimney flue is badly damaged with cracks and spalling, we may choose to resurface the flue completely with HeatShield. Using the same applicator and winch system, we place the applicator at the bottom of the flue and pull it upward, applying a “tie coat” to clean and prime the surface. Then in the same way, we apply the sealant at a thickness of ¼ inch along the length of the flue.

CeCure® Sleeve Relining

If you’re shopping for a new liner, the cost can add up quickly because metal liners and tile liners are priced by length. Using HeatShield, we can reline your chimney using cerfractory sealant and a CeCure® Sleeve. These products are a high-density, low profile ceramic insulation sleeve reinforced with stainless steel fabric. Then, we measure and lower this sleeve into the chimney, as it’s sandwiched between two layers of HeatShield cerfractory sealant using the custom foam applicator.

The foam applicator not only applies the sealant, but it also presses the sleeve in place before it is covered in another layer of sealant. Once dry, this lining system is as durable and long-lasting as stainless steel. It is also cheaper and safe for all fuel types.

I wanted to give 5 stars but they are very busy which meant I had a good wait for both the inspection/cleaning, then for a quote on repairs and then for the repairs. Their prices seemed a little high to me but I have nothing to compare with as they were highly recommended by someone I trust and other companies had plenty of negatives reviews which kept me from getting additional quotes. I am happy with the work and they promptly returned to fix a mistake that had been made. Chris the inspector, Jennifer in the office, and Alex and his repair crew were all pleasant and took the time to answer all of my questions. Alex and his crew even took their shoes off (it was winter) before entering my house without even being asked! So if you are not in a rush and want to ensure you chimney is as safe as possible then I think you'll be happy with Black Moose.

After a recent sweep of our chimney, it was discovered that our flue tiles were cracked. Black Moose techs were hard working, detail oriented and professional! Nice jobs guys! See you next year for my cleaning!

Excellent I highly recommend Black Moose Chimney and Stove; Kelly and Liam are awesome, they did a great job. Extremely professional, arrived early, went through everything with a fine tooth comb ensuring pellet stove was thoroughly cleaned. They also were respectful of my home, conscientious and cleaned up after themselves. Made sure stove worked prior to leaving and told me to call promptly if anything came up afterward. Will definitely use them again.

We've had Black Moose clean our chimney for a number of years.But recently, we had an emergency situation at our home involving our chimney & oil furnace flue, which was caked full of soot from a malfunctioning furnace. They came & cleaned out both flues in no time, even going up on the roof with snow on it! They cleaned up after their work in the interior rooms where the oil furnace and the woodstove are located. Great work. Reasonable prices. Very nice people. You can't go wrong with Black Moose.

Goods: The technicians know their business, very efficient in cleaning/inspection along with cleaning up after the 'dirty work'.Others: Communications could be more effective. Despite early coordination about scope of work (multiple flues within same chimney) the estimate provided did not reflect this and the final invoice was significantly more than the estimate provided.Quote for follow-on chimney relining was significantly more than that offered by other companies in the area (and far more than neighbors experienced for similar work accomplished by other companies)
