A wonderful accent to add character and dignity to an interior or exterior of a home, French doors are a pair of doors which are generally equipped with glass panes for most of their length. These doors are unique in that they open outwardly, and close towards one another to form a barrier. In some cases, French doors were considered a safety hazard. But, by way of modern advancements, this is no longer the case. Although they used to be reserved for outdoor spaces, such as the patio, they are now widely used for the interior of homes. As mentioned, installing French doors is a bit of a complex process, and you’ll likely need an extra set of hands for the process.

Firstly, the list of the materials you’ll need is as follows:

• Tape measure;

• Hammer;

• Power drill;

• Regular drill bit; 

• Paddle bit; 

• Hole saw; 

• Philips-head screwdriver; 

• Pry bars; 

• Carpenter's square;

• Chisel;

• Flush cutting saw;

• Rubber mallet;  

• Level (long in length); 

• Safety glasses; 

• Nails; 

• Screws;

• Shims.

You will also need a French door kit and all of the necessary hardware, including doorknobs and latches.

Getting started

Start by removing the old door frame. For this job, you will require the assistance of a hammer and a pry bar as they will help you to avoid damaging the frame that’s in place. It is recommended that you label the trim pieces after removal, as this will help you to decipher where each one will go following their reinstallation.

Using a level as well as a carpenter's square, check the opening of the space where you plan to put your French doors, making sure you have squared it off. Make sure not to skip this step, as paying close attention to these details will make the installation process much easier.

To install the new door frame, hold it up in place and make sure it is level. Use shims to firm it up into place, drilling pilot holes through both the frame and the shims. Following this, drill or drive nails in just deep enough to hold the frame in place.

Now, test fit the new doors to make sure that they remain snuggly in place. It is important to do this step before securing the frame permanently, as you’ll need the doors to be flush with one another while hanging above your floors at the correct height. Make any adjustments necessary, ensuring that the doors open and close correctly.

If you find that everything fits plumb in place, you can now secure the frame permanently. This job can be done using the proper screws for the material of your French doors. Once the door frames are in place, you can allow the doors to hang. Finally, install the hardware that you’ve chosen, or which came alongside your kit. For this part of the process, follow the instructions provided by the manufacturer.
