thanks for the replies so far. This is a million dollar house with lots of architectural windows over the door so a roof isnt an option. We will be there to address the construction defects as we know it has plenty. The landing which is now filled with what garbage they had laying around will be replaced with a draining stone system. We know the block will be sealed. Here's the interesting part. I spoke with a Dupont engineer and they said their product is the wrong choice for the application. I agree. I would like to see ice & water shield applied to the sheathing below grade, but am also concerned that the wood should breathe some.
So ideally what I am here for is suggestions as to how to protect the below ground (in landing) sheathing.
High end custom homes here use a lot of metal flashing. Especially copper door and window pans. I assume that there is wood framing behind the Tyvek? Was the porch filled with dirt? That wood should off never been trapped behind masonry with just Tyvek to protect it, especially in a wet climate such as yours. The best solution is to provide a roof or cover over the porch. Next best is to remove the door and make a metal pan of at least galvanized sheet metal. All the seams should be soldered and the front should extend down below the bottom of the wood and lap over the concrete foundation. The side of the pan should extend up the door trimmers at least 4in and the pan should also have a lip at the inside of about 1/2in across the bottom, this creates the “pan” and any water that get passed the door, door sill or flashing would be drained to the outside. The majority of the construction defects I see are because of poor waterproofing details and the reliance of materials like Tyvek as a fix all solution. I have a saying that go with that; “its not a submarine” so lets not try to design it as one.
