Old patio poured too high
I have a 1950's home and the original front door patio was poured too high. It's only at the front door (everywhere else around the house it is minimum 4" above a paved surface or 6" above landscaping.
It's 1" below the front door but the stucco on 2 sides extends all the way down to the concrete patio. During normal rains, this isn't a problem, but during long periods of heavy, blowing rain, the stucco gets very wet and water wicks into the basement. I checked from the basement and the foundation wall terminates a few inches BELOW the top of the patio. This means that when the stucco gets wet, it buries itself in that little channel between the patio and the stucco and eventually gets through the paper and trickles down the inside wall of the basement.
What is the best way to fix this? Removing the patio isn't an option because it's technically the ceiling of the cellar, and then we'd be into serious reconstruction of the structure in that part of the house. Should I cut away the stucco and flash it and then goop the hell out of the bottom/edges of the flashing, then re-stucco the bits i've cut out?
