i need help with a problem with a exterior part of the fireplace. it is leaning 6-7 inches away from the house. the inside looks good and we have gas logs not being used because (the gas company )said they were not vented properly. not been used in 10 years. the fireplace had to be rebuilt about 20 years ago due to a storm, and i guess that it was not done right then. i don,t know we had fires in it until the vented gas logs for a few years. it does not have to stay a full masonry fireplace since we have the vented logs i would like to make them work if possible but we need to do something ASAP, and as in expensive as possible. i am notsure where to start and what to save. PLEASE HELP!!!!
