My gutter on the rear of my single floor ranch house was damaged and I have found that the wood behind the facia is rotted in several places. I have to replace the gutter and I guess take off the facia and replace the rotted sections of wood? I have never messed with gutters before, but consider myself extremely handy. How tough of a job could this be? What should I look out for? Can I reuse the facia if I am careful when removing it? I want to do this properly, but also want to keep costs down.
