Thank you for reading my question.
I replaced our front door awhile back and everything went ok. It's a 36" exterior door with one side light, prehung.
After the door was in, leveled and screwed in place I realized that the bottom sill (plate?) and the concrete slab had a big gap.
Turns out that the new door has a sill with a slope, but the bottom of the whole prehung door box is flat, but the concrete under the door had a slope.
So now I'm left with a gap. The door is sealed on the bottom on the inside but as the slope grows, so does my gap. I filled the gap with a 1x6 PT cut at an angled the long way, but the gap wary a little from left to right so it's not perfect.
Could I fill this gap with self leveling concrete? Some kind of foam that holds up to the constant stepping on the door sill? Any other ideas?
Thank you for your help!
