1. I have an original 1971 exterior door on the side of my garage I need to replace. The door width is 30" which means it's not stocked at the big box stores so I have to order custom. I decided to go with a pre-hung. When I got a quote for the order, I noticed he put "slab width: 30" but later on it says "rough opening width: 32". So I double-checked the rough opening width of the existing door and it is 31.5". I'm wondering if that RO width in the quote is exact or not? The house has foundation footing on both sides of the door frame so I've got to stay within 31.5".
2. The guy also recommended I check the frame width because standard is 4 5/8". The problem is that I'm not sure where to measure from. There's a brick mold that buts up against the frame on the exterior. I'm wondering if I include the brick mold in the measurement or not. Either way, it's not 4 5/8". The garage is not drywalled so the frame on the interior already juts out beyond the studs so I'm thinking this measurement is not critical as long as its not larger and is at least as wide as the studs.
