been looking at putting an insert in my old masonry fireplace, I had a sweep come out last week and he told me at some point that I have had a chimney fire and should discontinue use until damage was fixed. He took pictures from inside the house and down the chimney on the roof and I had vertical cracks in my flue tiles and also missing grout and bricks in my smoke chamber also crown needs to be resurfaced due to cracks, firebox is warped and grout missing around edges of that also plus several other things. insurance company is sending another company to look at it later this week, my question is when they do the work do they have to bring my fireplace and chimney up to 2014 IRC codes house was built in 1969 and if so will insurance cover the cost of that also or will they only pay for what was damaged in chimney fire [liner and smoke chamber], sorry so long and Thanks for replies
