Hey all, I`ve got a house going up in Wisconsin and it is looking good if I do say so myself. I will try to post pics but first let me work on my typing. Can you help set me strait on pouring my chimney cap?
I have got a wood chase with the top being 3’x5′. It has one flue pipe from a wood burning insert that is 12″ The sides will get natural stone veneer with a poured cap .What is the best way to get a solid and water tight cap? I was thinking 3″ thick. My thoughts are to use the osb cap the carpenters have on there now ,support under as necessary,cut a hole for the pipe and cover the cap with water proof material put something like sillsealer around the pipe, rebar and pour. Then go back and caulk the joint between the pipe and the cap.
What am I forgetting there is always something right? anyway thanks for the feedback.

A poured concrete cap on a chase sounds like a bad idea to me. How are you gonna seal the joint around the metal chimney? Those metal chimneys don't last forever, either. Replacement would be a bear. I'd lean toward a metal chase cover.
You're almost as paranoid as the people that're trying to kill me.
Yep... poured cap would be a bear to work on for replacement... which WILL need to be done at some point in the future.
Stick with the manufactured caps.
Don't forget to include the spark arrestors... don't wanna be settin' your's or your neighbor's house afire.
