Hello, I have NO masonry skills or knowledge and am looking to have a hearth and fireback wall built for my new install. I have 2 quotes from masons and the materials cost about $800 and the labor has been from $2000-$3000. One guy told me that he would be in my house working for 96 hours! I just can't believe that this project could take that long? It will be a 54x54 hearth and a 54 " fireback that will be going to the peak at 116" and going down to 91 inches along the 5/12 pitch ceiling. I am definately a guy who has more time than money and want this install to be done right, last a long time, and look right. Is this a DIY project for someone with my skillset. I am pretty handy or at least willing to try and learn how to do projects. Recommend any good books on the subject?
