What You’ll Need

Before you get started, you’ll need to gather a few supplies. You’ll need a tape measure, a level, a drill, a saw (either a circular saw or a hand saw will work), and a few other tools that are specific to your door type. Make sure to consult your door’s installation instructions for a complete list of what you’ll need.

Preparing the Area

The first step is to prepare the area where the door will be installed. This involves removing any existing doors or windows, as well as any trim or molding. Once the area is clear, you’ll need to measure the rough opening and make sure it’s square. If it’s not, you can use a piece of scrap wood to shim it until it is.

Now it’s time to install the door. Start by attaching the door’s track to the rough opening, making sure it’s level. Then, install the door’s roller assembly onto the door, and position it in the track. Once the door is in place, you’ll need to install the door’s handle and lockset.

Finishing Up

Once the door is installed, you can finish up by trimming any excess materials and installing any necessary weather-stripping. Make sure to test the door to ensure it’s operating smoothly before you call the project complete.
