Hello, I am a new first time homeowner and within a few months of moving in to my house (built in 1915), I had a the chimney swept by a CSIA listed company and they didn't raise any issues with the masonry fireplace but did make a complete mess of my first floor-- there was soot everywhere that we spent the day cleaning up. In any event, my wife thought it made sense to have another company come out and take a look and do an inspection to make sure the fireplace was safe. I scheduled the appointment but in the meantime tested the chimney with some incense first and then a small fire followed by a couple larger fires. The smoke went up the chimney and all seemed to be in order. Just had the inspection and the inspector said I have some holes in some spots (images below) and he recommended "smoketite" at a cost of 1275 plus a cement gap at lintel for 250. I have no clue whether any of this is necessary, and plan on having a second opinion, but wondered if any of you experts had any thoughts based on the attached images. Also, he recommended completely changing my dryer vent and doing some video inspection to reline the natural gas boiler flue -- his description of the issue on that flue was "gas flue 4" 76,000, 7" 245,000 is not lined at base must be video scanned for relining. Not safe to use." He didn't give me an image for this one. Thoughts comments etc very much appreciated. Many thanks.
