I had a Majestic wood burning fireplace insatalled back in the 80"s and can locate the manual. I am not sure of the style. It has artificial stone surronding it to the ceiling. My concern is that it was covered with three feet of flood water recently. Is it still safe workable or do I have mold and mildew inside the wood frame now. How should I preoceed. To tear down or repair? Thank you.
