The siding on this chimney chase had been open to the weather for years. Water got in behind it, and the wood underneath was gone by the time we opened it up.
We stripped the chase down, replaced the rotted sheathing and trim, and ran new siding tight all the way up. New chase cover on top so the water sheds off the wood instead of sitting on it.
A chase is a wood box. Once water is inside it, siding is not a cosmetic issue anymore - it is what is holding the whole thing together.
Chimney chase and chase cover work across Greater St. Louis.
