French doors are a type of door often used in homes and businesses that consist of two door panels, each with its own handle, hinge, and lock. The doors are opens outward from the center of the door frame and are usually equipped with a security bar or chain to prevent them from being forced open. French doors can be made from a variety of materials, including wood, steel, aluminum, and fiberglass.

What You’ll Need

To open French doors, you will need:
-A drill
-1 inch hole saw
-Jamb saw or handsaw
-Cordless screwdriver or drill
-1/8 inch drill bit
-2 inch screws
-4 inch screws
In this project, you will learn how to open French doors for increased ventilation.

Step One: Check the Door

The first thing you need to do when you want to know how to open French doors is to check the door. There are two types of doors, and each type has a different way of opening. The first type is the single door, and this door has a handle on the inside and outside. The second type is the double door, and this door has two handles, one on the inside and one on the outside. If you have a single door, you will need to use a screwdriver to remove the screws that hold the handle in place. If you have a double door, you will need to use a screwdriver to remove the screws that hold both handles in place.

Step Two: Measure the Door

Before you do anything, you need to measure the door. Measure the width of the door at the top, middle, and bottom. Then, measure the height of the door at the left, middle, and right side. Use a tape measure or a ruler to get accurate measurements.

Step Three: Cut the Hole

Now that you have the rough opening framed and sheathed, it’s time to cut the hole for the door. If you are installing a pair of doors, make sure to mark the left and right door on the rough opening before cutting. This will ensure that you install the doors in the correct order.

To cut the hole, use a circular saw to make two perpendicular cuts through the sheathing, as shown in the image below. Then, use a utility knife or saw to remove the remaining material between the cuts. The hole should be big enough to accommodate your door, plus 1/4 inch on each side for clearance.

Step Four: Install the Hinges

Once you have the door in the correct position, it is time to install the hinges. The most common type of hinge for French doors is a full-mortise hinge. This type of hinge has a leaf that is mortised, or cut out, on both the door and the jamb. Installing this type of hinge is more difficult than installing a surface-mounted hinge, but it results in a much more attractive door.

Begin by holding the hinge in place on the door. Make sure that the knuckle, or joint, of the hinge is flush with the edge of the door. If it is not, you will not be able to close the door properly. Once you have found the correct position for the hinge, use a pencil to mark where the screw holes will go.

Remove the hinge and drill pilot holes for your screws. Be careful not to drill too deeply – you don’t want to damage the door! Finally, screw in your hinges and replace any hardware that was removed earlier.

Step Five: Hang the Door

Now that you have your doorframe and doors hung, it’s time to finish the job by hanging the door. Start by attaching the top hinge to the door. Then, holding the door in place, use a level to make sure it is even. Once you are satisfied with the position of the door, use a drill to screw the hinge into place. Repeat this process for the other hinge. Finally, use screws or other fasteners to secure the doorknob and latch in place.

Step Six: Finish the Door

The final step is to finish the door. If you are using a factory-made door, this will already be done for you. If you are using a door that you have made yourself, you will need to finish it by adding a layer of sealant. Once the sealant has dried, you can then add a layer of paint or varnish.


Now that you know the basics of opening French doors, you’re ready to tackle this project with confidence. Remember to take your time, measure twice and cut once, and use a level when installing your new doors. With these tips in mind, you’ll be enjoying your beautiful new doors in no time.
