I'm starting my first post with a question regarding my concrete patio demolition. The main reason I'm doing this in the first place is the patio slopes toward the house, and in heavy rain (and I live in a temperate rain forest), I am getting some water in my crawl space in that corner, so I want to reslope, redirect the downspouts away from the house, and eventually put pavers down instead of concrete.
The patio sliding door actually sits on the same patio, then just inside that part of the house is on slab,which is maybe 1/4 " higher than the patio (the crawl space begins just to the right of the door).
If I rent a concrete saw, how would I cut it flush with the door, or should I leave a bit of a "threshold" anyway. I just thought it might look funny going from the concrete to pavers.
Any help would be appreciated.
