Cheap bifold doors are tempting when you see the difference in price against a premium set, and sometimes a budget option is the right call. The honest answer is that it depends on what has been cut to hit the low price, because on a bifold the hardware and the fitting matter more than almost any other type of door. This guide explains what usually gets trimmed on a cheap set, where it shows up over time, and when a lower-cost bifold is still a sensible buy.
Why bifolds are so sensitive to cost cutting
A bifold is a set of panels that fold back like a concertina, hung on hinges and running along a track. Every panel has to line up, glide smoothly and seal tight when closed. That only works if the rollers, hinges and track are good quality and the frame is fitted dead level. On a cheap set, the corners tend to get cut on exactly the parts that keep it working, which is why a bargain bifold can feel very different to use within a couple of years.
Where the money usually gets cut
When a bifold is priced well below the rest, the saving normally comes from one or more of these:
Hardware
The rollers, hinges and locking gear are the heart of a bifold. Budget hardware can feel stiff from day one and wears faster, so the doors start to drag or drop on their hinges. Better sets use running gear rated for years of daily use, and it shows in how they glide.
Sealing and weatherproofing
Cheap gaskets and brush seals let in draughts and, in exposed spots, wind-driven rain. On a wide opening facing the Yorkshire weather, poor sealing is something you feel every winter. Quality sets have better weather seals and a threshold designed to keep water out.
Glazing and thermal performance
A low price sometimes means basic glazing units with weaker thermal performance, so the room is colder near the doors and the units can mist earlier in life. Look at the glass spec, not just the frame.
Frame strength
Slim, strong frames need decent aluminium or well-reinforced uPVC. A frame that flexes lets the doors fall out of alignment, which is when the smooth fold turns into a shove.
Where a lower-cost bifold still makes sense
A cheaper bifold is not automatically a bad buy. It can be the right choice when:
- The opening is small, so the doors are lighter and put less strain on the hardware.
- The spot is sheltered, for example onto a covered patio, where sealing is less tested.
- Use is occasional, such as a room you open up in summer rather than every day.
- The budget is fixed and the alternative is no new doors at all.
In those cases, a well-fitted budget set can serve for years. The key word is well-fitted, because even a modest bifold performs far better installed properly than a premium one hung badly.
uPVC versus aluminium on a budget
If cost is the driver, uPVC bifolds are cheaper than aluminium and can work well in smaller openings. The trade-off is chunkier frames and less glass, plus more flex on wider spans. Aluminium costs more but stays slim and rigid, which is why it suits big openings where a cheap uPVC set would struggle. Our aluminium sliding and bifold doors page shows the difference in the flesh.
What to check before you buy a cheap set
- The hardware brand and its guarantee. Good running gear is usually named and warranted.
- The weather seals and threshold. Ask how it keeps draughts and rain out.
- The glazing spec, including the energy rating of the units.
- Who is fitting it, because a level, square frame is what keeps a bifold working.
- The full guarantee, on the doors, the hardware and the fitting.
If a set is cheap because of a factory clearance or a simple spec you genuinely do not need upgraded, that is fair enough. If it is cheap because the running gear and seals have been downgraded, you may pay the difference in draughts and repairs later. Our window and door repairs team sees plenty of budget bifolds that need attention within a few years, which tells its own story.
The bottom line
Cheap bifold doors can be worth buying when the opening is small or sheltered, use is light and the set is fitted well. For a wide, everyday opening onto the garden, spending a bit more on hardware, sealing and fitting usually pays off in doors that still glide and seal years down the line.

FAQs
Are cheap bifold doors any good?
They can be, for small or sheltered openings with light use. The risk is on the parts you cannot see: budget hardware, seals and glazing wear faster, so a bargain set on a wide, exposed opening often disappoints within a few years.
What gets cut to make bifolds cheap?
Usually the running gear, weather seals, glazing spec and frame strength. Those are the exact parts that keep a bifold gliding and sealing, which is why a cheap set can feel very different to use over time.
Are uPVC bifolds cheaper than aluminium?
Yes, uPVC bifolds cost less but have chunkier frames and flex more on wide spans. Aluminium costs more and stays slim and rigid, so it suits larger openings where a cheap uPVC set would struggle.
Is it better to spend more on the doors or the fitting?
Both matter, but a good fit is not optional. Even a modest bifold works well if the frame is dead level and square, while a premium set hung badly will drag and leak. Never skimp on the installation.
