What Is HeatShield? – Chimney Liner Repair

Clay tiles have been used to line chimneys for decades. And although they can be very effective and durable, the heat and gases produced by the fire can cause them to crumble and crack over time. When cracks and gaps form in the liner, the liner must be repaired or relined for the safety and efficiency of the entire chimney system.

Is your clay tile liner in disrepair? A relining may not be necessary. The team here at Black Moose Chimney & Stove may be able to repair and restore your chimney liner with a cerfractory material known as HeatShield®.

chimney heat shield repair in Francestown NHThe HeatShield® Process

HeatShield® can be used for 3 different applications:

  1. Repair – If damaged or receding mortar joints in your tile liner are your issue, HeatShield® can be applied to the cracks and gaps to restore the liner. Once we’ve applied the product, we use a foam applicator to smooth over the product and make sure the repairs are airtight. We then video scan the liner to recheck our work.
  2. Resurface – Does your flue have cracks and damage throughout? Our technicians can apply HeatShield® to the liner in its entirety. We’ll apply a primer to prep the flue before using a custom-fitted foam applicator to smooth the product over the surface from top to bottom. Again, we’ll video-scan to make sure we’ve left a seamless, airtight liner.
  3. Reline – If your liner is in need of extensive repair, we may be able to restore it using the HeatShield® sleeve relining system. Just as we do in the HeatShield® resurfacing process, we’ll start by applying a primer coat to the entire flue surface. Next, our foam applicator will smooth a layer of HeatShield® over the entire flue. Once applied, we’ll slip a sleeve down into the flue, followed by another layer of HeatShield®. As always, we’ll video scan the flue to make sure our work was effective.

Is Your Chimney Liner In Need Of Repair?

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)
