How to Install Folding Doors: A Step-By-Step Guide

Doors are the most popular option for creating rooms or separating areas in your home. They provide privacy and reduce noise, which dividers, partitions, and curtains can't offer.

Moreover, doors come in different types, so you don’t need to stick with a classic style if you have a small space.

Folding and partition doors stand out among these options because they don’t take up much space. They slide neatly to the side, perfect for small rooms or open-concept layouts. They come in different materials and colors and are easy to open and close.

They are easy to put up as well. In this article, we’ll share steps and tips on how to install folding doors to ensure you have the ideal new feature in your home.

Preparing Your Home for Folding Door Installation

Installing folding doors is a straightforward process. However, you need to prepare for this project to avoid some missteps.

Below are some tips to help you prepare for installing a folding door:

1. Evaluate the installation area.

If you just had the area for the folding door (or a partition/sliding door, for that matter) built or prepared, you can skip this step. However, if you’re replacing an old door, take the time to check the installation area adequately.

Check the door opening, frame, and jamb to ensure they are still in excellent condition. They should be able to support the weight of the panels.

Sand down the rough edges if the door frame has uneven surfaces. If it has minor damage that can affect the quality of the installation, find out if you can repair it or have a professional handle it.

Also, evaluate the structural condition of the surrounding walls to ensure they can support the door and keep it secure.

2. Check the kit.

After ordering your folding door, check if it has all the parts. It should have the main components, which include the following:

• Main panels
• Lock pro­files
• Half panel
• Lock panel
• Lockset
• Brackets

Use the instruction manual as a reference to confirm that nothing is missing. Ask your supplier for replacements if there are one or more missing parts.

Also, check each part for defects. Damaged tracks or bent hinges can affect the functionality of a folding or sliding door. 

3. Prepare your tools.

Before installing your classic folding door, make sure you have the tools you need to do it.

Some essential tools are:

• Drill
• Drill bits
• Work gloves
• Safety glasses or any protective eyewear
• Wall plug
• Screws
• Level
• Measuring tape

Ensure you have the correct drill bits if you need to bore a hole into a hard surface. You should also have a pencil for marking areas.

Keep all these tools within reach when you’re ready to start working.

4. Clear the installation area.

Remove all furniture, rugs, and other objects near the doorway to have an open, safe workspace. If you’re replacing an old door, carefully take it down along with all the hardware, including its hinges and tracks.

Consider removing paintings and other décor near the surrounding walls to avoid getting dust and debris on them.

If you’re installing folding doors for your closet, remove everything inside it before proceeding to the actual closet door installation.

Once you’re done with these, you can proceed to the next steps.

Installing the Folding Door

Below is a step-by-step guide to installing a folding door:

1. Measure the top of the frame.

Use a measuring tape to measure the top of the frame. Next, use a level to draw a straight line down the center.

2. Position the rail on the frame.

Place the rail on the top of the frame and mark the spot where you will drill the screws.

3. Install the top rail.

Drill the holes in the marked area. Next, install the top rail and drill a screw in the middle.

4. Install the folding door.

Hold the door securely and drill the remaining screws on the rail. Make sure you install all the screws, which depend on the folding door’s width.

5. Install the side rails.

Position the side rails on the frame and drill pilot holes to prevent the wood from splitting. Next, secure the rails with screws. Start from the top and work downward to ensure it is properly aligned.

6. Put the locks.

Align the lock according to the manufacturer’s instructions and drill it into the wall. Next, install the door lock. Test the locks to make sure they are working properly.

7. Apply lubricant on the rail.

Apply a light layer of lubricant along the top rail to reduce friction and prevent squeaking. Wipe off any remaining product to prevent buildup on the rail and panels.

8. Check if the door is working properly.

Gently open and close the folding door several times to test its movement. Make sure it glides smoothly and aligns correctly.

If you’re not too confident about installing your new folding door, let a professional handle it. Ask the seller if they have a team to install it, or look for a trusted contractor.

Maintaining Your Folding Door

Once you’ve installed your folding door, keep it in top shape with the following maintenance tips:

• Wipe the door frames, panels, and locks with a clean microfiber cloth or sponge at least once a week. You can use a mixture of water and gentle dishwashing liquid to clean them, but don’t get the panels too wet if you have a wooden sliding folding door.
• Clean the rail with a vacuum. Use the brush attachment to remove debris from this part.
• Apply lubricating oil on the rails, locks, and door handles every two months to keep them working smoothly.
• Regularly inspect the panels for cracks or structural damage. Call a professional to repair these issues.

Whether you're getting a folding door to save space or to give a room a modern look, this feature will be a great upgrade to your home.
