A few things to reinforce the door are, changing screw lengths and replacing the strike plates.

Let’s take a look below at the steps that you can take to reinforce an interior door.

What Are My Steps

When you looking to conduct a project like interior door reinforcement you will want to make sure you follow a few steps. Keep in mind that these steps are in place to ensure you don’t damage the door and the project is completed properly. Let’s take a look:

  1. Door brace – place a door brace up against the door for added protection. There are a variety of door braces that you can use to prop up against the interior of the door. The most common style is a 45-degree angled bar that extends from the door to the floor.
  2. Door frame – change the door frame to a steel frame. This will prevent a burglar from being able to kick down the door. Wood framed doors can splinter when kicked in. Steel doors do not splinter. This type of door frame can also prevent the use of a crowbar to gain access.
  3. Door hinges – replace the door hinges with some stronger hinges. Install multiple hinges that are at least 3 and 1/2 inches in length and 1/10th of an inch thick. Use long screws to secure them to the door frame. This creates added support and less of a chance the door can be kicked in.
  4. Door barricade – install a door bolt barricade bracket on the each side of your door and then add the barricade bolt across the door. The brackets are secured to the door frame with long screws and are wider than the door itself. Once the barricade bolt is extended the door cannot be opened.

Exterior Doors

Exterior doors are important to take a look at as well. This is because you want to make sure you have a heavy-duty door. The idea, as mentioned above, is to keep intruders out. Deadbolt locks are a great way to make the door secure and keep unwanted people from coming into the home.

Other Recommended Maintenance

Now that you understand what are some ways to reinforce your interior doors, it’s important to check on what types of doors you have. You might have a few hollow core doors in your home.
