Hi, I am getting a water leak on the interior part of my sliding door. It's leaking from the wood casing above the door. The exterior is cinder block, then brick. Pretty sure there are weep holes in the brick above the door. Not sure if the weeps are directly above or a few rows of brick, then the weeps. Also is pre cast stone above the door. Last leak was last year, and I put mp1 caulking between the brick and the pre cast stone joint. I only get a leak w heavy rain. Any solution or feedback would be appreciated. Thanks
