Only needs about a 5% pitch, and by your level it has an angle and it's in the right direction already.

That looks right to me---pour some water on it and see if it runs off --

Thanks everyone, I'll pour some water on it tomorrow.
My other sills have lots more pitch than this on.
I'll post the result tomorrow.

According to what/who? Did you just pull this out of your rear end?

The industry standard is typically 15%, but it's relatively hard to accomplish, and some don't care for the aesthetics of that much pitch.

We always shoot for 5% MINIMUM. Row lock sills are notorius for leaking backwards at the joints, they're not a pvc waste pipe or concrete slab, so those generalizations don't apply here...........

That specific brick is showing signs of water penetration, then a freeze/thaw cycle happening.

Plan on a few years from now having to replace the entire sill, and at that time you can increase the pitch a few degrees.

bricks will get wet - especially if it rains OR 1 pours water on them,,, i'd worry more about the seal between the brickwork/window,,, looks like caulk to me w/slight loss of adhesion,,, we see that many times on balconies where the typical complaint is leaking water inside the condo,,, we remove the caulk &, if possible, insert some denver foam then seal w/sika np1,,, IF there's no room for foam, we recaulk then seal over the caulk w/np1

still wondering about the 5* myself,,, then again, brickies never seal joints - they use mortar thanks be to God,,, we get called yrs later when it costs MUCH more to repair :smile: life is good
