How are you other windows installed? Normal procedure is the installer of said window is responseable to seal it up..........................

I agree with your mason. We would have installed that window further to the exterior - far enough to seal it to the brick, hiding the drainage plane. Then you could have the interior trimmed back to the window.

Seriously that window is upside down. Your weep holes are at the top and need to be at the bottom. It will leak 100%. Other than that I agree that trimming in matching aluminum is pretty normal from that point on although it would look different from the rest of your windows. If that bothers you than a new window will need to be ordered fitting closer to the brick opening.

Great catch WD! I missed that. The installers obviously didn’t know what they were doing.

Yes over time the sealant or glazing tape that holds the glass into the frame may loosen up and will make it very easy for water to get between the frame and glass. The weep holes allow it to leak out. Without them or if they're at the top instead, the frame of the window will fill with water and eventually leak to the inside where the stops are. If its winter time the water would freeze and could crack the mainframe....... I once replaced a window that was 5 or 6 years old and had leaked from day one, it was a 3 lite slider and whoever installed it had it in backwards. The weep holes were turned inside facing the living room..... I hope they make it right for you.

Once you see water draining out of those weep holes you know your in trouble.Anyways, I have done a lot of dumb things but not that one.

Good catch on the weepers being upside down. Too funny. The windows usually have stickers on them these days with directional arrows to boot.

Given the apparent overhang, the couple of issues that have been noted (weep holes and drainage plane) are less problematic but more indicative of some skill gaps.

Great comments above, particularly the catch by WD... While there really isn't a hard rule about the depth that window should be set, there's definitely some red flags about the competency of the installers. Maybe they just made a simple mistake, maybe they are total hacks. No idea. I will say though that I'd never leave a window unfinished to the exterior like that. They can set it where the want as far as depth, but they should also be cladding and sealing the opening IMO.

Vinyl windows generally have a depth of 3 1/4". At that point, when installed in an RO as opposed to an existing frame, you have the choice to push it to the interior or exterior. If you push it out there would be a jamb extension or return of some sort extending in. Given that you mentioned tile, they likely pushed the window IN up to the tile in lieu of adding a JE which could be tricky. That just means that the window is inset more and the exterior trim makes up the more shallow depth on the new window.
