Newbie here so thank you all for reading. Have a wood burning fireplace built around the mid 1990s. Rarely used, maybe once or twice a year. Never swept since it was an older woman's house and it was rarely used. Tried to have it swept now and was told it can't even be swept because of the heatilator tubes. Something about it not being up to code and he's legally not allowed to sweep it (there is no access door for the heatilator tubes was noted). Also told the size of the firebox is too big for the size of the liner in the chimney and was offered electric or wood inserts ranging from $3K to over $7K. If the fireplace will now be used regularly, we'd like to have it swept so its not a hazard. Is the not legally being able to sweep it thing true? Also, he said because of the size difference with the firebox, smoke probably comes into the house. When it was used, we didn't have smoke in the house that I ever remember. Would it not be noticeable or I was getting the hard sell from the chimney company to spend more money? I already paid a couple hundred dollars for this "advice" and I thought I'd ask here before I have to pay again for a second opinion.
