I bought a 1925 built house last year. When we got it we had a chimney guy come out and fix the top and check it. He re built the top of the chimney and said we are good to go. I asked about it being lined and he said it was fine.
This year I had another company come out with a camera. They cleaned the chimney and ran a camera. The smoke box is just brick. Seemed like an issue but he said it was still ok. Above that there is the original terracotta liner (rectangular). Some places where the terracotta section meets another there are gaps where some of the mortar is missing. Not a hole just a depression. The largest was about the size of my index finger, length and depth (average adult male). Meaning I could lay my finger in the groove and it would fit perfect. Only one of the gaps is that large and most places the grout or whatever it is is fine.
Basically we had one guy say its fine another say its a fire hazard and it would be $5000 to repair it.
- How dangerous is it? Small fire risk and keep using it, or oh my god the house is going to burn down anytime if you use it.
- An estimate for a 4 foot smoke box and 20 foot high chimney relining does 00 seem high?
- Most importantly can I use it through the holiday season? I used it all last year and since its been cold this year.
Thanks
