I could use some advice. We bought a very nice custom 4 year/old custom home a year ago. Whenever it rains, I've noticed some water dripping into the basement from over a basement window. After some heavy rains, I've discovered that the top of the foundation wall is flooded with water and dripping down the interior walls. After the rains stopped, I inspected outside and discovered that there is water flowing between the foundation wall and the flashing for the deck. So there's flowing water behind the flashing, not good. Here's a view from under the deck.
Here's another view looking straight-up at the flashing from the bottom. The dark stuff behind the flashing is water-soaked OSB. The white stuff you see is evidently mold.
The places where the water is leaking seems to be over two sets of sliding glass doors that lead from the house onto the deck. Here's what they look like from the top of the deck.
My guess is that this water is getting sucked under the sill, and entering the basement this way. Needless to say, I'm a little freaked out. Can anybody hazard a guess as to how water is getting behind the flashing and into the basement? And even more important, what do I do now? Many thanks!
