How to Prepare for Install Bifold Doors
To prepare for installing your new bifold doors, you should measure and check the dimensions of the door opening to ensure it matches with the size of the doors that you have.

Remove any weatherboards or framework so that the gap where your new bifold doors are going to go is fully accessible.
How to Install Bifold Doors Yourself - Step by Step Guide
Below is a step-by-step guide on how to install bifold doors in your own home:
Step 1
Add damp proofing to the blockwork surrounding the gap where your new door is going to go.

Step 2
Use spirit levels and a series of plastic wedges to build up the bottom of the aperture to ensure that the base of the door is completely level. You should take measurements across the entire width of the opening to ensure that every single part is level.

Step 3
Double-check the measurements of the width of the aperture and then cut the threshold piece to size and attach the end stops. The threshold piece can then be fitted into place on top of the wedges.

Step 4
You then need to construct the outer frame. However, be sure to leave the fixtures loose so that adjustments can be made if needed later on.

Step 5
Then, you can fit the frame into the opening. If it’s quite a tight fit, use a rubber mallet to tap the frame into position with care. Then adjust each vertical pillar, ensuring that it is perfectly upright.

Step 6
Create pilot screw holes at the top of the frame with a metal guard in place to ensure the brickwork isn’t damaged unnecessarily.

Step 7
Using the correct sized drill bit, a larger, more permanent hole needs to be created right through the door frame and into the brickwork where the door can be secured.

Step 8
Wedge any gaps to ensure the pillars remain completely vertical and in place and then insert the fixing screws. Repeat this process on both vertical pillars.

Then, secure the bottom of the pillars in the same way. Continue to check the pillars regularly to ensure that they are completely vertical using a spirit level.
Step 9
Once the frame is securely in place, you can then add the door frames. Start from the furthest end of the master opening door. Simply slide the doors onto their hinges and attach them securely.

Step 10
Next, you will add the glass panes to the door frames. Mount the glass panes onto the door frames one by one and then push them into position so that they’re sitting tightly.

Step 11
Add beading around the glass pane. These simply snap on into the place and form a tight lock keeping the glass pane securely in place. Use a rubber mallet to ensure the beading is tightly in place.

Step 12
Next, insert a rubber trim into the space between the glass and the beading. This acts as a waterproof, soundproof, weatherproof seal around the glass. Push the rubber into position and then trim off any loose ends to give a neat finish.

Step 13
Now that the doors are installed, you can complete any finishing plastering work that needs to be done. Cover up any exposed brickwork and ensure that the gaps around the window frame are nice and neatly plastered.
