Bi-fold doors are a popular choice for homeowners looking to add both style and functionality to their space. Known for their ability to maximize natural light and seamlessly connect indoor and outdoor areas, bi-fold doors have become a go-to solution for patios, conservatories, and internal room divisions. However, before jumping into an installation, it’s essential to understand key factors like cost, how to install bi-fold doors, how to adjust them, and the differences between internal bi-fold doors and external bi-fold doors.
This comprehensive guide will answer all your questions regarding bi-fold doors, helping you make informed decisions whether you're building new doors or upgrading your existing ones.
How Much Are Bi-Fold Doors?
One of the first questions on anyone’s mind when considering bi-fold doors is: "How much are bi-fold doors?" The cost of bi-fold doors depends on several factors, including material, size, the number of panels, and the type of installation. Here's an overview of the costs involved:
1. Cost Breakdown of Bi-Fold Doors
- Basic Bi-Fold Doors: These typically consist of uPVC or standard aluminum materials. They are ideal for internal bi-fold doors and can cost between £200 and £500 per door, depending on the size and design.
- Mid-Range Bi-Fold Doors: Timber bi-fold doors and aluminum bi-fold doors offer a more premium aesthetic and durability compared to basic uPVC models. You can expect to pay between £500 to £1,000 per door for these types, which are commonly used for internal as well as external bi-fold doors.
- High-End Bi-Fold Doors: For a truly premium look, many homeowners choose aluminum or wooden bi-fold doors with additional features like triple glazing or thermal insulation. These doors generally cost between £1,000 and £2,000 per door or more. Such doors are excellent for creating an elegant, energy-efficient solution for external bi-fold doors.
The price also depends on whether the bi-fold doors are for internal use or as external doors connecting a room with a garden or patio. External bi-fold doors often require higher-end materials due to the exposure to weather elements.
Tip: For long-term value, consider opting for energy-efficient materials like double or triple-glazed bi-fold doors. Though they come at a higher price point, the investment will pay off in terms of energy savings.

How Do You Install Bi-Fold Doors?
The installation of bi-fold doors is a bit more involved than standard hinged doors, but with careful attention, it’s certainly doable. If you're planning on installing your bi-folding doors at home, here’s a step-by-step guide to help you through the process.
1. Measure the Opening
The first step to installing bi-fold doors is ensuring the opening is the correct size. Accurate measurements are crucial for a proper fit. Measure both the height and width of the opening and make sure the dimensions match the specifications of the bi-fold doors you’ve selected.
- Width: The width of the opening should be at least as wide as the combined width of the bi-fold door panels, leaving some extra space for the tracks and hardware.
- Height: The height should be measured from the floor to the ceiling. Keep in mind that the track at the top and the base track will add to the overall height.
2. Prepare the Area
Before installing, make sure the floor and the wall around the door opening are level and free from obstructions. This step is important to ensure that your doors will open and close smoothly without rubbing against the frame or the floor. Additionally, make sure the wall surrounding the opening is structurally sound, as bi-fold doors need secure anchoring.

3. Install the Track
Bi-fold doors operate using top and bottom tracks. The first step is to attach the top track to the ceiling or frame, ensuring it’s perfectly horizontal. Use a level to verify that the track is aligned correctly. Once the top track is securely in place, attach the bottom track along the floor. Make sure both tracks are parallel to each other and well-secured.
4. Hang the Panels
Start by hanging the first panel on the top track. Ensure it is aligned and level, then move on to adding the other panels. Most bi-fold doors come with specific instructions on how to install the panels, and it’s important to follow these carefully to avoid damaging the doors.
5. Install the Door Handles
Once the panels are hung, you can attach the handles or knobs. Many bi-fold doors use specialized handles that allow for easier folding. Make sure the handle placement is at a convenient height for everyone in the household.
6. Final Adjustments
Finally, test the door to ensure it opens and closes smoothly. You may need to make slight adjustments to the tracks or panels to ensure they move freely. Ensure the doors are aligned, and the panels fold properly without obstruction.

7. Professional Installation Option
While DIY installation is possible, if you’re not confident in your skills or you have large or complex bi-fold doors, it’s advisable to consult a professional installer. They can ensure your doors are installed correctly and are functioning optimally.
How to Adjust Bi-Fold Doors
Even after installation, you may need to adjust your bi-fold doors over time due to wear and tear, temperature changes, or shifts in the structure of your home. Here are a few common adjustments you might need to make:
1. Adjusting the Alignment
If your bi-fold doors are out of alignment, they may not close properly. You can adjust the alignment by:
- Loosening the screws on the top and bottom tracks.
- Moving the panels slightly to reposition them.
- Tightening the screws back once the alignment is corrected.
2. Adjusting the Height
If the door is scraping the floor or ceiling, you can adjust its height by altering the positioning of the rollers. Most bi-fold door systems come with adjustable rollers that allow you to raise or lower the panels to ensure they fit snugly in their tracks.
3. Lubricating the Tracks and Hinges
To keep the door moving smoothly, periodically apply a silicone-based lubricant to the tracks and hinges. This helps prevent wear and keeps the door from sticking.
4. Fixing a Sticking Door
If your bi-fold door is sticking or doesn’t fold properly, it may be due to debris or dust in the tracks. Clean the tracks regularly, and if the issue persists, adjust the roller tension or track alignment as needed.
Conclusion
Bi-fold doors are a fantastic addition to any home, providing both aesthetic and functional benefits. Whether you’re considering internal bi-fold doors to divide rooms or external bi-fold doors to create a seamless transition between indoor and outdoor spaces, it’s essential to consider factors like cost, material, installation, and maintenance. By choosing the right doors and keeping them properly adjusted, you’ll enjoy the versatility and beauty of bi-fold doors for many years to come.
