What do I do about the hole in the exterior wall? Should I keep the exerior flue in place in case someone wants to use it in the future? This solution avoids repairing the exterior siding and the cutout in the roofline, but I can see people scratching their heads as to a non-functional flue. Removing it all means repairing the interior and exterior of the wall. I'm not sure if I need to address the square cutout in the roof overhang. I'm not DIY so would any contractor who knows how to build a wall be able to do this?

If you want yours removed, I would seek out a reputable handyman that has experience in siding repair, carpentry, roof repair as well as painting. Make sure you check them out pertaining to the experience by getting references and referalls from friends, family, co- workers, etc who have had similar projects done and they are satisfied with that persons work. Make sure they are insured and legal!
