The Cost of Internal Bifold Doors

Bifold doors are an excellent statement piece for your home; they’re space saving, excellent at dividing or opening up rooms, and they look fantastic. 

As with any new home addition, it’s important to consider all the factors that influence price – so you can make an informed decision about what you’d like. Bifold doors naturally come with a higher price tag than standard doors – this is due to features like full panel glazing, the track mechanisms, hardware, and other additions that a standard door doesn’t have. 

Here we’ll be breaking down the features that will influence the price of your bifold doors – and give you a few options to choose from. All so that you can make the best decision for your home, wallet, and lifestyle.

Five Factors That Influence The Price of Internal Bifold Doors

Rather than giving your round-about prices for doors and their sizes, we’ve decided to break down the features that you’ll be choosing between to help you decide what is worth the price. Each door comes with their own set of features  that and determine how expensive the final cost is – from glazing to the number of door panels to installation – we’ll cover it all here. 

1. Size

The number of panels will typically influence the cost of the door more than its actual size.

This is due to the cost of the bifolding hardware. A bifold door might have six or more panels, each with a tether not only to their neighbors but also a long rain, along which a carriage runs.  Though the number of panels will determine the price more than the length of the door.For example, our 5+0 panel doors vary in size by almost two metres, but they each cost the same.

At Aspire Doors, you’ll find prices that reflect the number of door panels:

• 2 Panel Bifold Door:  between £400-£700
• 3 Panel Bifold Door: between £500-£800
• 4 Panel Bifold Door: between £800-£1,000
• 5 Panel Bifold Door: between £800-£1,300

2. Installation

Do you just need the door installed? Or do you need to adjust the wall opening as well?

Installation costs usually run between £600-£1,200.

Though this will depend on what your needs are. If you’re fitting a bifold door into an opening that is already available, then the cost of installation will just cover fitting the door.

If you need to enlarge or shrink the opening in your wall to accommodate your door, this can get expensive quickly. If rot or damp is found in the wall, then this could further complicate things. Anything that slows down the actual fitting will increase the cost. 

Factors influencing cost of installation:

• The size of the door: Larger and heavier doors will cost more to install

• Type of door: More complex and heavier materials will cost more to install 

• Where you live: Travel may affect cost to install

• Easy of Access: Installation in difficult-to-reach areas will cost more than average

• General Complexity of Installation: More complex = more expensive

3. Material

Is your door engineered, solid, or veneer timber?

Most quality internal bi-folds are made from timber, with aluminium and uPVC generally being the preserve of external bi-fold doors.  The cost of timber bi-fold doors will vary.  Engineered timber doors, which combine several different lengths of timber into a warp-resistant whole, are the standard – but you might cut costs by going for something less prestigious.  When considering materials, bear in mind that inferior materials will not hold their shape, nor their value, and they’ll require more regular maintenance.

Materials Compared

• Engineered Softwood: Typically less expensive and easier to customise

• Oak Veneer: A more premium material, slightly more expensive with an engineered core. 

The cost between these two won’t vary widely, so it depends on the look and feel that you’re going for.

4. Glazing

Glass will always cost more than solid panels.

Part of the charm of a large, folding door, is that it’ll introduce more glass into the room.  More glass leads to a greater sense of space, and more light dispersal through your home.  The more glazing you use, the more the door will cost – though other factors tend to be more influential.

Glazing Options:

• Clear Glazing: The standard choice for bifold doors. These start from around £400 with standard two panels

• Frosted Glazing: Perfect for increasing light while maintaining privacy. Start from £490

• Mirrored Glass: Ideal for closet and bathroom doors. Start from £719

• Solid Panels: To close off rooms and maintain privacy. Start from £460

5. Finish

Fully Finished will typically cost more than unfinished.

Getting the door fully-finished at factory level will cost a little bit more, but it’ll save you the trouble of having to finish the door yourself.  Factory finishes tend to be more resilient than those you might apply at home, so they’ll save you the long-term cost of touching up your door each time something knocks against it.  

On the other hand, if you’d like to get the job done yourself in a particular way, applying the finish yourself is the only way to proceed! 

• Our Unfinished Pine internal bifolds are one of our more affordable choices, starting at around £300. They’re ready to be stained or painted any colour you’d like!
• Where our fully finished oaks doors are ready to be hung and start at around £500.
• If you prefer something in the middle, our white primed doors are covered in a primer so that they can be coloured with a fresh coat of paint, and start at £400.
