How hard is it to build a chimney for a wood burning fireplace?

• Tile liner can just be stacked, but it doesn't hurt to mortar them. You must use the "L" shaped brackets (at least in my building code area) You attach it to the existing brick wall, and then the other part of the "L" goes into the mortar of the chimney. Keep the chimney from seperating from the wall. Yes. Built my own. by Ahhhhhhhhh screw it

• Just anecdotal & to add to screwits response. A neighbor added a fireplace & brick exterior chimney himself. Did a beautiful job inside & out, but without a permit. He had to tear it down to the footing ( which passed) , file for a bldg permit & have the work inspected & approved.. Aside from bldg & fire codes it would have voided his homeowner's insurance. Rebuilt exactly the same way & passed. Got the skills , go for it but notify the ins co, get plans approved & work inspected. All about the paperwork. Best regards by split dog
