What Affects Aluminium Bifold Door Costs?
The following are the main factors that affect prices and some professional tips on keeping the cost of your aluminium bifold doors as low as possible:
Door Sizes and the Number of Panels
When determining how much you will pay for the installation services we provide, the first factor will be the size of your space. The door configurations are the most significant criteria in determining bifold door costs, whether you are installing aluminium, timber or UPVC bifolds.
The more panels you need means higher product costs, as the mechanisms are much more complex for a bifold design so the costs can jump up quite rapidly. Larger numbers of panels also increase the installation time, which can also easily push overall bifold door prices higher.
Site Access and Installation Difficulty
If you want to install any kind of sliding doors on a site that is difficult to access you will find the project takes longer and more labour intensive – and therefore pushes prices. A good example might be installing large bifold panels at height, in remote locations or a curved door shape.
Both interior and exterior doors may still prove tricky to install, such as when installing bifold doors on a period property, which may have an uneven floor surface and other imperfections that require greater site preparation. Our team can fit doors for all types of homes.
Colours and Finishes

Although being able to pick your ideal colour with our bifolds, the powder-coated aluminium doors cost a bit more than the uncoated types. Similarly, if you opt for a certain finish, such as a particular door handle, lock or type of patterned or privacy glass, costs can go up further.
We help our customers with our start-to-finish design service, which includes products to suit most budgets. More cost-effective options for finishes, such as lower-cost handles or films that you overlay onto the door panels, are clever strategies for lowering aluminium bifold door costs.
Type of Glazing
Double or triple glazing can increase thermal efficiency but it will be quite a bit more expensive to install triple glazing across a large array of bifold panels. As a result, smart glazing choices can help balance your costs a bit. Large panels can still be very energy efficient with double glazing.
You might even choose a special acoustic glazing, such as when installing bifolds on bedroom balconies in a flat, or even add more layers simply for better thermal performance, but be aware that any type of additional feature of the glazing will push up costs.
Installation Team Quality
Top installation teams not only deliver the best results for high-security, energy-efficient and long-lasting bifold doors, but they also do the work faster and more efficiently. The best installers have processes nailed down and prepare the site for swift installation, resulting in smooth work.
In our own home improvement company, we rely on professional memberships in many trade associations such as AlUK and training on the latest products or installation techniques, which greatly reduces time on site. Less time on site means less expense and lower installation costs.
Supply and Installation vs. Supply-Only Service
A supply-only service, such as the one we provide, can give you the lowest product costs, but this is only suitable for trades or FENSA-certified installers. While competent DIYers can fit many kinds of doors and windows, they typically require additional training, certification or experience.
Sloppy DIY installations can reduce the effectiveness of your bifold doors too, lowering energy efficiency and therefore decreasing your return on investment. A professional installation can therefore affect aluminium bifold door costs over the long term.
Other Tips for Keeping Aluminium Bifold Door Costs Low

Whether you are installing large internal or external bifold doors, there are a couple of tips to make sure you get the lowest possible costs. Professional suggestions include the following:
- Consider UPVC: UPVC bifold doors will be a lot less expensive, and compromising on the door material might mean you do not compromise on a glazing choice, finish or another thing you really want from the installation. UPVC is great for very big projects.
- Try other patio doors: French doors can make a delightful alternative to bifolds if you are worried about how much you could spend. Prices are much lower thanks to their simple design, and they still provide uninterrupted views while in the open position.
If you can make certain compromises then you can still get an incredible home improvement, no matter what your budget or the specifics of your situation.
