We will break down how long these installations take and explore additional, relevant subjects, such as how to install bifold doors and what issues may arise. Bifold doors are popular due to their flexibility, utility, and capacity to let more natural light in.
Let’s start by looking at a bifold doors price comparison. In this section, we’ll also discuss the labour costs and supply costs specifically, as well as the factors that shape the overall price.
The average cost of fitting a two-metre bifold door is about £2600 to £3400. You’d likely pay between £3600 and £4400 for a three-metre bifold door, or around £5100 to £6000 for a four metre bifold door.
Moving on to the labour cost specifically, a door fitter would likely charge about £150 to £200 a day. In general, a bifold door is usually fitted by two labourers, meaning that the average labour cost will end up at £300 to £400 per day in total.
This would translate to a total trades price of approximately £300 to £800 to fit a regular two or three metre bifold door.
However for a four metre product, expect the installation cost to more likely land between £600 and £1200. These are standard bifold door sizes.
As for the supply only costs, to have a small bifold door installed of two metres in size would cost around £2300 to £2600. Expect to pay approximately £3300 to £3600 for a three metre bifold door, or up to £4500 to £4800 for a four metre bifold door.
How much you’d pay to fit bifold doors will vary depending on a wide range of factors. Firstly, the size/type of bifold door is the most important cost element. Some of the most common bifold door types are uPVC, aluminium, and timber.
Beyond that, where you live and ease of access are also relevant. The reason that location influences the total cost is because labourers charge different rates in different regions of the country. The number of panels is relevant too, as it may be a 3 panel bifold door or a 6 panel bifold door, to give some examples.
|Size of Bifold Doors
|Total Installation Cost
|£300 to £800
|£2300 to £2600
|£2600 to £3400
|£300 to £800
|£3300 to £3600
|£3600 to £4400
|£600 to £1200
|£4500 to £4800
|£5100 to £6000
We’ll now take a closer look at the different bifold doors based on their material. In the following subsections we’ll discuss the features, pros & cons, and costs of different types of bifold doors.
Whether it is solid timber or engineered wood, timber-based bifold doors are a fairly common choice among homeowners. Notably, engineered timber is a stronger option than solid timber.
In general, solid timber bifold doors cost about £2500 to £3500 for frames and approximately £4500 to £5500 should the frames consist of composite timber.
Timber provides a natural aesthetic and one that offers a more traditional look than uPVC or aluminium.
As for the downsides, engineered timber may warp if it is too exposed to moisture or sunrays. In general, timber is not as conductive as metal with lower thermal efficiency.
Further, these types of doors are high-maintenance as compared to metallic of uPVC bifold doors.
✔ Common issue
✔ Natural aesthetic
✔ Engineered timber is especially strong
✖ Expensive as far as bifold doors prices go
✖ Timber is not as conductive as other materials
✖ Timber has lower thermal efficiency
Like with most metallic bifold doors, aluminium bifold doors are almost as costly as timber doors with an aluminium frame costing about £2500 to £3500.
Aluminium is a very strong option, allowing for thinner frames and more glass. In addition, aluminium bifold doors come with a thermal break to help with thermal efficiency.
Beyond that, these doors are often more eco-friendly (particularly as many are made largely of recycled material and sometimes up to 100%), low maintenance, and there is a wide choice of wood-effect finishes and colours available.
✔ Very strong material
✔ Often eco-friendly
✖ Still quite expensive
These doors are just as strong as wooden bifold doors but longer-lasting. They are also the least expensive option with frames costing around £1000 to £2000.
uPVC bifold doors are fairly low-maintenance, though they should be cleaned about once a year. On the other hand, uPVC doors have a low level of thermal efficiency, even less so than wooden bifold doors.
Further, uPVC bifold doors are the least eco-friendly option, they can appear cheap, as well as being a lot wider than timber or aluminium doors. Also, notably, uPVC doors do not fit well on period properties.
✔ A uPVC bifold door is as strong as timber
✖ Low thermal efficiency
✖ Least eco-friendly choice
✖ May appear cheap
We’ll now look at the steps involved in fitting bifold doors. We’ll also touch on additional work that you may choose to pay for.
Unless you decide to fit the bifold doors DIY, the first step involved in the process will be to hire a contractor.
To find the right door fitter, you should contact professionals/companies and acquire at least three quotes.
It’s worth your time also asking for some references to ensure that you’re choosing the right contractor for the job.
On the day of the job, the door fitter will need to ensure that the structure which will be used to attach the top bifold door track is strong enough to support the weight of the doors and frame.
Next, the sill should be prepared for assembly before the frame is assembled.
Then the frame should be added to the opening and made level and square. Packing must be used until the frame is tight and secure, before holes may be drilled into the structure on a given side of the frame to fix the bolts.
Once this is complete, the head and sill should be fitted to make sure that the sill has been made level and the jams are vertical.
As soon as the fixings have been fitted to the frame, the hinges may be attached per the instructions of the manufacturer. Then, the multipoint lock should be added prior to hanging the doors.
After the locks and hinges are fitted, the bottom and top pivot hinges must be adjusted as needed to ensure that the doors are vertical and secure once installed.
Of course during this process, the various parts will be added (if they are not already pre-attached) such as the bifold door handles.
There are many added jobs you may wish to pay for once bifold doors have been installed. For instance, to have a new front door fitted would cost you about £800 to £1200.
For new windows, you may pay somewhere in the range of £500 to £2500, depending largely on the material used.
It may also interest you have a new patio constructed to go with your new bifold doors and on average, this would cost around £1000 to £1750, again also heavily dependent on the material of your choice.
In most cases, it may be too challenging for an average DIY enthusiast to fit bifold doors as the process can be quite complex.
However, if you feel confident in undertaking this task, know exactly what’s involved and have a grasp of any necessary safety precautions, then it is possible to fit bifold doors DIY.
There are building regulations you’ll need to take into account as laid out on the Planning Portal website.
Notably, these regulations apply specifically to England and Wales and the rules in Scotland and Northern Ireland may differ.
It is unlikely that planning permission will be needed, unless in specific circumstances, such as if you live in a listed property or designated area.
Unless specific approval is required, a contractor will not generally need to sign off the work. Among the hazards associated with fitting bifold doors are the risk of injury from carrying large objects like the door frame or other elements of the installation.
Injury could occur if a large part of the door frame fell on top of you or if you strained your back while lifting.
There’s also the less serious but nonetheless undesired risk of a poor installation. If you perform the installation work incorrectly, you’d need to pay more to hire a professional to come out and complete the work for you anyway. So all in all, if in doubt, hire a contractor.
As with having any new fitting added to your home, there are some disadvantages worth considering. Firstly, the work can be quite expensive and disruptive.
If planning permission or/and building regulations approval are required it is unlikely but possible that your application(s) will be rejected.
In this case, you’ll be informed as to why your initial application(s) weren’t approved. Then, you’ll need to apply again with the necessary changes made.
A: This type of door is a single door that folds back in two parts. These sections fold together with one on top of the other thus reducing the apparent size of the door in half, opening up more room once they’re opened. Backdoor bifold doors tend to consist of two doors and four sections in total.
A: You may need to adjust a bifold door if it comes off its track. In order to do so, first, open and close the doors to locate exactly where the issue is.
Try with the lead door to start with. You may find that it's not sitting correctly in the opening or that it's binding to the door jamb. Either way, a horizontal adjustment will be required.
To fix this, adjust the hinges at the threshold or sill using an Allen key. You may adjust the track hinges if required. Keep at it by sliding the doors until they become flush and are fixed comfortably next to the other.
However, if the doors are popping or dragging out of place, you’ll have to adjust the height of the tracking system. To achieve this, the bolt must be extended and then pushed until the doors are lowered to find the perfect balance.
This will be a matter of trial and error. It’s worth trying this yourself before hiring a professional. However, if the issue persists, you should contact a company or labourer.
A: This will depend on the material used. For instance, uPVC bifold doors may last for 25 to 35 years but aluminium bifold doors come with an estimated life expectancy of 40 to 50 years.
A: In most cases, they’re about the same but with very wide sliding doors, the price can quickly accumulate, in a way that isn’t seen with bifold doors.
A: It is just that, a bifold door that has no frame. Though it has edges and tracks, a frameless bifold door is, at first glance, entirely glass.
