How to Install a Prehung Door: A Step-by-Step Guide

Introduction

Prehung doors are an easy and convenient way to upgrade your home’s interior. They come pre-assembled in a frame, making installation simpler and faster. However, proper installation is crucial to ensure the door functions correctly and lasts for years to come. In this article, we’ll cover all the steps and tips you need to know to properly install a prehung door.

Pre-installation preparation guide

Before you begin installing your prehung door, there are a few important preparation steps to follow.

Measuring the opening

To ensure your prehung door fits properly, you’ll need to measure the opening first. Here’s what you’ll need:

  • Tape measure
  • Level
  • Pencil
  • Safety goggles

Use your tape measure to measure the width and height of the opening at three different points: top, middle, and bottom. Take the smallest of these measurements and subtract 1/4-inch from the width and 1/2-inch from the height to get your door’s exact size.

Removing old hardware

Before you install your new prehung door, you’ll need to remove the old door and hardware first. Here are the tools you’ll need:

  • Hammer
  • Screwdriver
  • Pry bar

Use the pry bar to remove the trim around the door frame. Then, use the screwdriver to remove the hinges and latch from the old door. Finally, use the hammer to remove the hinge pins.

Inspecting the frame

Now is the time to inspect the frame to ensure there is no damage or rot. If there are any issues, repair them before proceeding with installation.

Step-by-step instructional guide

Now that you’re prepared, let’s move on to the step-by-step instructions for installing your prehung door.

Creating a level opening

First, you’ll need to make sure the opening is level. Here’s what you’ll need:

  • Shims
  • Level

Use the level to ensure the opening is level both vertically and horizontally. If it’s not, use shims to adjust it. Make sure the shims are placed every 10-12 inches and are not too tight, as this can cause the frame to bow.

Fitting the door into the frame

Next, fit the door into the frame. Here’s what you’ll need:

  • Painters tape

Use the painters tape to temporarily secure the door in place. Then, check to make sure there are no gaps between the door and the frame.

Securing the door in place

Once you’ve checked for gaps, it’s time to secure the door in place. Here’s what you’ll need:

  • Screwdriver

Begin by securing the top hinge, then the middle, and finally the bottom hinge. Make sure the hinges are flush with the door frame and that the screws are tightened securely. Finally, attach the latch to the door frame, making sure it’s flush and secure.

Simple and quick tips guide

These additional tips can help make your prehung door installation more successful.

Using shims

When using shims, make sure they’re not too tight or too loose. You want them to provide support without causing the frame to bow.

Checking the door’s swing

Check the door’s swing by opening and closing it. If it’s not swinging correctly, adjust the hinges until it does.

Proper weatherstripping

Make sure your door is properly weatherstripped to prevent drafts and energy loss. Check the seal around the entire door, including the bottom and sides.

Specific door type guide

Different types of prehung doors may require additional steps. Here are some tips for double-door and storm door installations.

Double-door prehung doors

To install double prehung doors, install one door first and secure the hinges. Then, install the second door by checking the spacing between the two doors and securing the hinges.

Storm doors

To install a storm door, refer to the manufacturer’s instructions for any additional steps. Typically, you’ll need to attach the door hardware and hang the door in place before securing the frame.

Checking the door’s levelness

Make sure the opening is level before installing the door. If you skip this step, the door can become misaligned, making it difficult to open and close.
