Anodized aluminum patio door installed over copper flashing
I’ve seen some similar questions but thought I’d ask my specific issue.
I have a very large Fleetwood aluminum patio sliding door that was installed over copper flashing with no material in between. The bottom of the window track/frame is anodized with a black coating.
We only learned today about the mistake in not using a true barrier between such as bituthane tape. However the stucco has gone on the outside (browncoat only) and the sheetrock and trim on the inside.
It will be very expensive to remove everything and start again. However it looks like we could gently pry up the bottom rail and insert building paper most of the way back. Or another material (not sticky, that won’t be able to slide under).
This area gets a lot of rain in the winter but is dry for several months (N California).
Question is, can anyone say with any certainty what kind of problems to expect in 5, 10, 20 years? Of course it will be cheaper to address it now while the contractors are still at the jobsite etc. But still a few $K and more delays.
Thank you, community 🙂
