Hi, This is my first post here. I have a lot of upcoming projects this year so I hope this site will b helpful :). I am getting ready to install a rear entry door to my house. I have chose to do a prehung door. I measured 3 times width to the studs and 3 times the height. I removed the trim of course to do this and went with the smallest measurement. My concern is the threshold is slanted toward the outside. Will there be a big gap due to this when I got to hang the new door? It's a concrete threshold. Do I have to measure the outside to get the slant measurement? I am a bit confused about this. I have hung interior doors before but not an exterior. So I want to get my measurements right before I take them to Home Depot and buy a door. Thanks for your time and help.

My house is facing west and one of the front window leaks on stormy rainy day. Couple of contractors took a look at it and they could not figure out the source of the leak. The leak is coming from inside top of the window where it meets the wooden frame. The front side of the house is stone veneer covered and there is a window directly above this one which does not leak. Please see the pictures for details. Any help in identifying where the water gets in would be greatly appreciated. Thanks.
