**Background:**
20 year old house with original Bilco classic bulkhead door (see image below). Water was leaking in around the metal Sill and rotted the top step and stringer. I removed all the old caulk around the perimeter which was in bad shape and replaced it with a heavy hand of Sika Polyurethane Construction Sealant per the Bilco caulking instructions. Additionally, I purchased and installed the Bilco weather stripping kit for additional protection.

**Problem**
We got some rain recently and water is still penetrating what appears to be under the recently caulked sill (see pictures below). Am I missing something? Is it saturating the concrete and getting under the Sill?
