How much do bifold doors cost?

Bifold door prices in Australia typically range from $1,650 to $5,500, excluding installation. The final cost depends on the material, size, number of panels, and whether installation is included.

What are bifold doors?

Bifold doors are a type of door system made up of two or more panels that fold back on themselves, concertina-style, along a track. Hinged together, these panels slide and fold neatly to one or both sides, allowing for a wide, unobstructed opening. This makes them an ideal choice for connecting indoor and outdoor living areas or dividing rooms inside the home.

Commonly used as exterior doors opening onto patios, gardens, or balconies, bifold doors are typically constructed from aluminium, timber, or UPVC. They come in a variety of styles, colours, finishes, and panel configurations to suit both modern and traditional homes.

Many bifold doors also incorporate energy-efficient features, such as double-glazed glass, which can help reduce heat transfer and improve thermal performance. If you’re considering installing bifolding doors, speak with local suppliers to explore the styles, sizes, and configurations that best suit your home and lifestyle.

What factors affect bifold door cost?

The total bifold door cost for your home can vary widely depending on several key factors. Understanding these influences will help you plan your budget more accurately and choose the right option for your space.

Size and configuration: Larger openings and doors with more panels generally cost more than smaller, simpler configurations. Custom sizes or unusually shaped openings may also increase the price.

Material: The material you choose has a major impact on bifold door prices. UPVC is usually the most affordable, while aluminium and timber bifold doors tend to cost more due to their durability and premium finish.

Glazing: Double glazed bifold doors are more expensive than single glazed options, but they offer improved energy efficiency and better noise reduction—potentially saving you money on heating and cooling over time.

External vs internal bifold doors: External bifold doors typically cost more than interior ones because they require stronger weatherproofing and more secure locking systems.

Hardware and accessories: The quality and style of bifold door hardware — such as handles, tracks, and locks — can influence the total cost. High-end or custom finishes will generally increase your overall spend.

Installation: Professional bifold door installation is highly recommended and will add to the final cost. However, proper installation ensures the doors function smoothly and are sealed correctly for energy efficiency and security. You can expect to pay anywhere between $1,500 and $4,000 or more for the installation of exterior bifold doors.

Brand: Well-known or premium bifold door brands may charge more, but they often provide better craftsmanship, warranties, and after-sales service.

Location and site access: If your property is difficult to access or if extra structural work is required, expect additional charges for delivery and installation.

Because of these variables, the cost of bifold doors can range from a few thousand dollars to tens of thousands. For the most accurate pricing, it’s best to get tailored quotes from local suppliers and installers.

How to install bifold doors?

Installing bifold doors can be a tricky task, but with some patience and the right tools, you can achieve a quality DIY install. Here are the steps to install bifold doors:

1. Measure the opening

Before you buy your bifold doors, measure the width and height of the opening where you want to install them. Make sure to measure at multiple points to ensure the opening is square.

2. Purchase the doors

The track should be installed at the top of the opening, and once level it needs to be attached to the header with screws.

4. Attach the pivot brackets

The pivot brackets should be attached to the top and bottom of the opening on the hinge side of the doors. Make sure they are level and securely attached.

5. Install the doors

Place the bifold door panels in the track and secure the bottom pivot brackets to the floor with screws.

6. Put on the door handles

Install the door handles on the center of the bifold doors.

7. Adjust the door panels and install the door guides

Ensure the door panels are level and aligned properly before installing the door guides at the bottom of the door opening to keep the panels securely in place.

8. Test the door

Open and close the door a few times to ensure it’s functioning properly.
