Security Doors questions, answered by experts

Minor modifications like grab bars and threshold ramps can be DIY, but professional services ensure compliance with ADA standards and structural safety.

You want a small gap of 1/8 of an inch between the door and the jamb. However, the gap size depends on the direction the door swings and whether it contains glass. You will also want to aim for the same size gap on all sides of the door, so it opens and closes smoothly.

In most cases, a pre-hung door is a better option, not only because it’s far easier to install as a DIY project, but also because you’ll get a new frame and a new door at the same time for a more complete upgrade. Replacing a door costs more with pre-hung doors, but the additional investment is usually well worth the money. Pre-hung doors require fewer tools and less experience to install properly. With that being said, a slab door might be better if you’re on a tight budget or have a custom wall opening size that a pre-hung door won’t match.

You want plenty of room between your pre-hung door and the framing in your wall to allow for shimming to get the door into the perfect position, so aim for about 1 inch on the top and both sides. That means you should make your rough opening about 1 inch taller and 2 inches wider than your pre-hung door. You’ll then use shims to stabilize and level the door before installing it.

There are a few different reasons why shotgun houses have two separate front doors. Shotgun homes with two front doors are also called double shotgun homes, which can be two individual homes that share a wall. Other reasons include improved ventilation throughout the home and better access to other rooms.
