Bespoke Bifold Door FAQs

Here at ATT Fabrications, we get asked questions about our bi-folding doors all the time. You may have some questions about bifold doors and we’re here to help answer. Discover the answers to some of our most common questions below. 


How much are custom bifold doors?

The price of custom bi-folding doors vary depending on the scale and specifications of the project. Our bifold doors, here at ATT Fabrications start at £1,638 for uPVC and for aluminium doors our prices start at £2,005. If you are looking for extra features such as different glass types and extra panels, you can add these on at an extra cost. 

What size opening do I need for a bifold door?

 Here at ATT Fabrications, we offer bi-folding doors in widths that span from 1800mm to 600mm and a height of 1750mm to 2500mm. As long as your opening fits between those size requirements, we can help you!

How do I measure for replacement bifold doors?

Finding the right measurements for your bespoke bi-folding doors needs to be accurate for us to be able to create the doors as well as fit them. So, how do you measure for Bifolding Doors? 


Take your tape measure and hold it at one end of the width and get a friend or family member to hold the other end. You want to ensure that the tape measure is held tight as a dip may leave you with an inaccurate measurement. Note down your width in mm. 


Horizontally measure the external brickwork at 3 or more different places. Take the smallest dimension as openings can vary at different points. Deduct 10mm from the reading to allow for fitting tolerance. This also means that the doors can be packed into the opening level and squared easily.


Ensure that you have a steady footing on a ladder or stool if you cannot reach the top of the frame. Then take your tape measure and place it by the top of the frame and measure to the floor. This will provide you with a reading that you can put into our bespoke designer. 

How long does it take to fit a bifold door?

Fitting time of bifold doors depends on the size of the project and the capabilities of those fitting the fixtures. You should expect the fitting time of bi-folding doors to be around 3-4 hours for regular size projects. If existing doors need to be removed, this can extend the process.
