Outside feels closer.
Bifold doors can transform how a rear extension or living space connects with the garden. Whether you're replacing an older door or working from plans for a new opening, the installation details matter just as much as the product.
- 01Fold-away access. Panels stack compactly to one side in suitable configurations.
- 02Considered thresholds. Discuss practical access, drainage, floor build-up and weather performance.
- 03Made to suit the project. Frame choice, glazing, opening layout and structural preparation all need to be considered together.

A better result starts here.
A well-fitted bifold is about much more than the number of panes. These are the choices worth making carefully.
Panel configuration
Choose how much of the wall opens up and where the panels will stack, subject to supplier configurations and opening dimensions.
Finishes and glazing
Explore aluminium profiles, colours and glass options. We confirm the available combinations against the actual supplier range.
Thresholds & seals
Opening preparation, levels, weatherproofing, drainage and careful finishing are essential considerations for a long-lasting installation.
Bifold doors
Panels fold together towards one or both sides, creating a broad opening between the house and garden.
Sliding doors
Larger sliding glass panels can create an uninterrupted view while closed. Another strong option for contemporary projects.

Before you open up.
Straightforward answers about bifold installation, systems, fitting-only work and local enquiries.
Can you install bifold doors I have already purchased?+
Yes. DF Installations welcomes installation-only enquiries. We review the door system, dimensions, structural opening and fitting requirements before confirming whether we can undertake the installation.
Do you supply and fit aluminium bifold doors?+
Yes. We offer supply-and-fit enquiries as well as installation only. We will discuss the opening size, configuration, finish and glazing before preparing a project-specific quote.
How many panels can a bifold door have?+
Three-, four-, five- and six-panel arrangements are among the common options. The available configuration depends on the manufacturer, system, width and how the doors are intended to stack.
Do bifold doors open inwards or outwards?+
Both arrangements can be possible depending on the selected system. Outward opening is common, while inward opening may suit some layouts. Always confirm the actual manufacturer configuration before ordering.
Can bifold doors have a low threshold?+
Many systems offer threshold options, but the right detail depends on exposure, drainage, the floor build-up and accessibility needs. A low threshold should be selected with weather performance in mind.
Can you fit bifold doors into an existing opening?+
Often, yes, subject to a survey and the suitability of the existing opening. Structural alterations, new lintels and building work are assessed separately and are not automatically included in the fitting price.
Are bifold doors better than sliding doors?+
Bifolds can open up more of the width when folded back. Sliding doors often provide larger uninterrupted glass panes when shut. The best choice depends on your available space, views and how you use the opening.
How much does bifold door installation cost in Hertfordshire?+
Costs vary according to the number of panels, dimensions, access, threshold design, material, condition of the opening and whether supply is included. Share photographs and approximate dimensions for a tailored quote.
Which areas do you cover?+
We are based in Hatfield and work across Hertfordshire, Bedfordshire and parts of North London, including enquiries from St Albans, Welwyn Garden City, Stevenage and nearby locations. Share your postcode to confirm coverage.
Can you install bifold doors for builders or developers?+
Yes. We undertake fitting enquiries for homeowners, builders and development projects, including installation-only work where the door system is already supplied.
How long does bifold door installation take?+
The time on site depends on the opening, number of panels, access and finishing requirements. We discuss the proposed installation programme once the specification and site conditions are understood.
