Aluminium Bi‑Fold Doors for Seamless Garden Connections

Free Quote

Bi‑fold doors fold neatly to one side, giving you a completely open wall that connects your kitchen, living area or commercial space directly to the outside.

Our aluminium bi‑folds are designed for slim sightlines, smooth operation and reliable performance, making them ideal for extensions, refurbishments and new builds across Berkshire and the South East.

Tailored to Your Opening

Every set of bi‑folds is made to measure. We’ll help you decide:
– How many panels you need
– Where they should stack
– Whether you want a traffic door for everyday use
– Which threshold detail best suits your floor levels and drainage

The result is a door set that works with how you live, not against it.

Comfort and Security as Standard

Our bi‑fold doors are designed to be used daily, not just admired.

They offer:
– High‑performance double or triple glazing for thermal comfort
– Quality seals and gaskets for weather protection
– Robust locking systems and secure hinges
– Smooth running gear for easy operation, even on wider openings

Frame Design, Colours and Hardware

Aluminium frames are slim yet strong, giving a light, contemporary appearance that sits well in both modern and period homes.

You can choose:
– A refined palette of external and internal colours
– Matching or contrasting handles and hinges
– Glazing bars or more minimal frames to suit the architecture

We’ll guide you through combinations that feel balanced rather than busy.

How we work

From Concept to Installation

Initial conversation

We begin with a discussion about your project, your space, and what matters most to you, whether that is slim frames, thermal performance, ease of access, or budget.

Survey & specification

We carry out a detailed site survey, take accurate measurements, and advise on suitable configurations, frame material, glazing, and finishes. This is where we help you decide between aluminium and uPVC for your specific opening and goals.

Installation & finishing

On installation day we protect surrounding areas, remove old frames where required, install the new sliding doors, and complete all sealing and trims with care. The aim is a neat, weather tight result that feels integrated with the property.

Aftercare

Once the doors are in place we carry out final checks and show you how to operate and look after the system so it continues to perform smoothly.
