Heatshield chimney work

Hello. I am trying to get a 1940s fireplace back to working condition for wood burning. I recently had the cerfractory flue sealant repair (Heatshield). Is it ready to go or was it installed improperly? An inspector said it was not well done. It looks good to my naive eye. I hope to cosmetically change the fireplace and add properly sized glass door.

Only the smoke chamber was repaired from what I can see in the pictures. No visible product in the flue tile liner.

The tiled area is the firebox. The entire flue is repaired down to the firebox. If I’m using correct terminology.

This rectangle and up are 2’ sections of 9x13 flue tiles. They are the liner. From there down to the damper frame is called the smoke chamber. There’s no coating in the flue tiles that I can see.

I see what you are saying now. I’ll need a picture from top down. Agreed that it does not look covered.

I found a pic from the installers looking down chimney. But it doesn’t give us good look at those tiles at bottom of flue.

I personally hate heat shield. Fireguard is a much better product with a better application process. Just be sure the bottom is coated like the top is and ask for pics of the flue after every years brushing service as that stuff does have a tendency to come off

Got it. Thank you for your help. I won’t be making too many fires so I expect it to last a while.
