How to Install Interior Doors Step-by-Step

If you’re looking to give your home a makeover, learning how to install interior doors is a game-changer. It not only adds style and character to your space but also provides an opportunity to make your rooms more private. By following our comprehensive interior door installation guide, you’ll be able to swap out old, unattractive doors for new ones that reflect your personal taste and style. So, let’s dive right into this DIY interior door install guide and help you achieve your home renovation goals.

Understanding Door Types: Prehung vs. Slab Doors

Before we delve into the steps of how to install an interior door, it’s essential to understand the two main types of doors you’re likely to encounter. These are Prehung doors and Slab doors. These types differ in how they are installed, their cost, and the level of skill required to install them.

Prehung Doors

Prehung doors come with the frame already attached. These doors prove ideal for new construction or situations where the existing door frame is damaged. While the installation process might appear complex and daunting, it’s relatively straightforward when you break it down into manageable steps. A key part of installation is ensuring that the door is level to prevent problems with opening and closing. We’ll discuss leveling door frames a little more later in the guide.

Slab Doors

On the other hand, a slab door is just the door itself, without any frame, handles, or hinges. The benefit of slab doors is that they offer more versatility in terms of design. However, they require more work during installation, especially if the door needs resizing. Understanding how to fit a slab door correctly is important for ensuring ease of operation and the door’s longevity.

An Interior Door Installation Guide: The Step-By-Step Process

Now that we understand the different types of doors, let’s break down the steps on how to install interior doors. For this guide, we’re focusing on prehung doors, as they are the most common for DIYers and relatively easy to install.

Step 1: Prepare the Doorway

Installation begins with preparing the doorway. It’s important to ensure that the floor beneath the door is level and the rough opening is the correct size. Additionally, one should clean and remove any debris in the areas where the door will be installed to prevent any issues during installation.

Step 2: Position the Door

Next, carefully lift the entire door unit and position it into the rough opening to ensure it fits correctly. Brace the door temporarily with a few wedges or shims.

Step 3: Level the Door

This step is crucial in ensuring that your door operates correctly. Use a spirit level to check if the door is plumb in the opening. Adjust the door by adding or removing shims until the level indicates that the door is perfectly vertical. The concept of shimming interior doors will be discussed further in upcoming sections.

Step 4: Secure the Door

Once the door is level, it’s time to secure it. Drill pilot holes through the door frame and into the wall studs. Following this, secure the door using a screwdriver and screws. Make sure the door operates smoothly before moving on to the final steps

Step 5: Insulate and Trim

Insulate around the door frame to eliminate drafts and trim any excess shims. Finally, give the door and the frame a new coat of paint if necessary.

Shimming Interior Doors

Shimming is a key part of the door installation process, especially when ensuring the door fits perfectly within its frame. Shims are thin wedges of material that are used to fill small gaps or spaces between objects, in this instance, the door and its frame. Shimming a door involves inserting these strips at various points to ensure stability and levelness of the door within its frame and adjusting as necessary.

Replacing Interior Doors

If you’re taking on a door replacement project, the process is essentially the same. However, an added step involves removing the existing door. This removal can accompany a few challenges, hence patience, and care is required to avoid causing damage to your walls or flooring during the process.

When installing doors in Miami-Dade or Florida, be sure to check with your local authorities on any building codes and regulations that must be adhered to during the installation process. Following them is necessary to ensure that your home retains its value and remains a safe place to live.
