I have a broken flue tile in the flue used for my wood stove. After looking at the web for answers about what to do to fix the problem, I like the pour in place system but, I have not been able to find anyone that has used this system. I have contacted different contractors but they could be bias and I was hoping to speak with someone who has had the pour in place installed and get some advice. The first question is the cost relative to putting a ss system in? Are there any drawbacks to installing a pour in place? Which system will last longer? Which system is better and safer? Any help would be appreciated.
