You can just see the top of the drain pipe sticking out to the left of the shadow.

The contractor that built this addition had a little decorative box there so I never saw this until now. It lasted through two winters with that little box and a bale of straw that was put there for unrelated reasons, but I feel like that was dumb luck.

What would you do? Keeping in mind a tear-out and replace is out of the question before spring now.

Thanks,
