French doors are elegant, easy to use, and come in various materials and styles, making them a versatile choice for any door inside your home. Many people prize these doors because the glass panel additions allow natural light into the room. There are also frosted glass additions for those who want more privacy. Installing French doors can seem daunting, but the process is not overly complicated with the right tools and knowledge.

Gather Your Tools and Materials

Before installing French doors, it helps to have everything on hand and within reach. You should gather the following tools to ensure you have everything necessary.

• Measuring tape
• Level
• Manual or battery-driven screwdriver
• Wood screws
• Utility knife
• Caulk gun
• Shims
• Door insulation
• Pry bar
• French door kit

When shopping for a French door kit, make sure to purchase one that is pre-hung. Pre-hung doors come with the attached frames and hinges, making the installation much more manageable. Make a checklist of your supplies and tools, and place them in the installation location within easy reach.

Measure the Door Opening

Before installing a French door kit, you must measure the door opening, whether it is a door to a closet or a bedroom. Proper measurements are crucial to installation and ensuring the new door will fit in the space properly.

Measure the doorway at the top, middle, and bottom. If the measurements differ, use the smallest to ensure a uniform opening. Pre-hung door frames will fit into rough openings, though some adjustments may need to be made.

Remove Your Old Door

If replacing a door, you must remove the old one first. Remove the door from its hinges using a manual or automatic screwdriver. Once removed, remove the door frame using a pry bar. Be careful when removing the frame so you do not damage the surrounding wall. Cutting the nails with a utility knife is the most efficient removal if your frame is nailed.

Prep the Opening

After removing the entire door and frame, you must prepare the opening for the new door installation. Use your level to check the opening and ensure it is level. You should also use a carpenter’s square if you have one on hand. Add or remove shims to ensure perfect levelness. The opening must be level to ensure the French doors open and close smoothly.

Dry Fit the Doors

The next step in installing new doors is to dry-fit them in place. Dry fitting means putting the new frame and door into the opening and ensuring it fits securely. Do not secure the door until you confirm there are no gaps or unequal spacing around the doors. Check the opening and doors to ensure they sit correctly. Use shims if necessary to correct any issues before installing the door.

Secure the Door Frame

Securing the door frame is essential for a proper installation. First, place shims where you will install the hinges for a stable connection. Using wood screws and your manual or automatic screwdriver, attach the door frame to the wall through the hinge jamb. Start at the top and work your way down to the bottom. Check leveling as you go, and correct any issues with shims.

Install the Hardware

Follow the door manufacturer’s instructions for installing the hardware. Make sure the lockset aligns with the holes perfectly. Some French doors come with a dummy door handle. Following the manufacturer’s instructions will ensure a proper fit and function. Contact the manufacturer immediately if there are any missing pieces or fit issues.

Insulate the Frame

You will need to insulate the frame, whether it is an interior or exterior door. You can use insulating foam or fiberglass. Ensure you do not overfill the frame edges to prevent the door from bowing. It is essential to be careful with spray foam applications since they expand rapidly. If you overfill, remove some insulation until you achieve a perfect fit.

Caulk the Frame

Your newly installed French doors will not look complete without caulk work. Once you install the installation, apply a thin, continuous bead of caulk in the small gap between the new frame and the wall. If you put too much or make a mistake, wipe it with your finger or a wet cloth to smooth out the caulk. Most caulk varieties will dry within 24 hours, but some can take up to 10 days. Keep this in mind when purchasing and installing caulk. You cannot paint the caulked areas until they are entirely cured.

Test the New Doors

After installing your new French doors, you must test them. You should open and close the doors from both sides, making sure the hardware works correctly and the door does not slide too closely to the frame, causing opening issues. If there is any resistance, make minor adjustments. Your dry-fitting should have made you aware of any problems before installing. If you skipped the dry-fit step, remove the door, frame, and adjust the opening before reinstalling.

After checking the function, make sure the hinges and hardware are all tightened appropriately. Apply any finishing touches like stain or paint, and the door installation is complete. It would help if you periodically made minor adjustments with the hinges and hardware as the door settles, especially in humid environments.

Take the Necessary Steps to Install Your New French Doors

Installing French doors is not overly challenging, even for novices. Before starting, it is important to measure the space for a proper fit and assemble all the tools and materials.

A dry fitting will ensure the French door assembly fits the opening, and you do not need to make any adjustments. Skipping dry fitting can lead to resistance to opening and closing or an improper fit that makes the doors less secure.

Installing new French doors can bring a touch of class to any home. They work well as closet and entrance doors. French doors come in multiple materials and designs. Be careful when installing these doors because of the fragile glass inserts.
