Looking for new sliding doors for your home? Understanding the costs involved can help you plan your budget and make the right choices. We’re a family run business with 50+ years of experience with aluminium home improvement products.
In this guide, we’ll look at the typical prices of aluminium sliding doors in 2025, along with the factors that affect these prices.
What Makes Up the Cost of Aluminium Sliding Doors?
When homeowners ask about the cost of aluminium sliding doors, there’s rarely a simple answer. The final price depends on several key factors – from the size of your doors to the type of extras you choose. Let’s break down these factors.
Size and Configuration
Size is one of the most significant factors affecting the price of sliding doors. At North East Bifolds, we offer sliding doors in a range of sizes, from modest patio doors to large glass walls that open up entire rooms.
Our doors can be made to measure, with widths ranging from 1.2m to 9m and heights up to 2.5m. Naturally, larger doors with more panels cost more than smaller ones. A standard two-panel door will cost less than a five-panel system that spans the width of your home.
The configuration of your doors also matters. Door systems with multiple panels and tracks tend to cost more due to the additional materials and more complex installation process. If you have larger openings in your home, you’ll typically need more panels, which increases the overall price.
Frame Quality and Materials
The frame is the backbone of any sliding door system, and its quality directly affects both the price and performance. Aluminium frames are priced slightly higher than uPVC alternatives. At North East Bifolds, we only offer aluminium sliding doors, as we feel it is the best material for this product.
Aluminium is an inherently strong material that allows for slimmer frames and larger glass panels than uPVC. This means more natural light and better views from your living space. The slim frames of aluminium doors give them a modern, sleek appearance that many homeowners prefer and suit contemporary properties.
Additionally, aluminium frames are lightweight yet extremely durable. They won’t warp, rot, or rust like other materials might. When properly finished, aluminium can withstand the UK’s variable weather conditions for decades, offering a lifespan of up to 45 years compared to uPVC’s typical 20-30 years.
Our high-quality aluminium frames include thermal breaks, which is a barrier within the frame that reduces heat transfer between the inside and outside of your home. This feature improves the door’s thermal efficiency, potentially lowering your energy bills over time.
Hardware and Security Features
The hardware components of sliding doors include the tracks, rollers, handles, and locking systems. Better quality hardware ensures smooth operation and greater security.
At North East Bifolds, we install the EROS 3 Star Cylinder lock on all our sliding door systems to give you peace of mind. This advanced locking system has achieved the prestigious Sold Secure Diamond 2024 certification, offering comprehensive protection against common break-in methods.
We also offer different hardware and handle finishes in several colours, including black, anthracite grey, white, and brushed chrome, to match your door colour and home design.
Threshold Options
The threshold is the bottom part of the door frame that you step over, and it’s another feature that affects both price and functionality. At North East Bifolds, we offer two main threshold options:
- A stepped threshold that provides extra protection against rain and draughts.
- An upstand threshold that allows for the flooring to be flush with the internal threshold, creating a seamless transition between indoor and outdoor spaces.
Typical Price Ranges for Aluminium Sliding Doors
While every project is unique, and prices can vary based on specific requirements, here’s a general guide to what you might expect to pay for aluminium sliding doors in 2025.
Entry-Level Aluminium Sliding Doors
Price range: £1,500 – £3,000
This price bracket typically covers:
- Smaller two-panel sliding doors (around 1.8m – 2.4m wide)
- Standard double glazing
- Basic handle options
- Standard security features
- Basic, non-RAL colour choices
These entry-level options still provide the core benefits of aluminium sliding doors, including durability, natural light, and access to your outdoor space. They’re a good option for replacing existing patio doors or adding external doors to smaller openings.
Mid-Range Aluminium Sliding Doors
Price range: £3,000 – £6,000
In this middle bracket, you’ll typically find:
- Wider two-panel or three-panel systems (around 2.4m – 4.5m)
- High quality double glazing with better thermal values
- Wider range of colour options
- Potential for some customisation
Mid-range sliding doors represent a good balance of quality and value. They may offer improved thermal efficiency and security compared to entry-level options, but the added price is mainly due to their extra panels and size.
Premium Aluminium Sliding Doors
Price range: £6,000 – £12,000+
At the higher end of the market, you’ll find:
- Large multi-panel systems for wider openings (4.5m – 9m)
- Full colour customisation including RAL and dual colour options
- Optional extras such as integral blinds
These premium systems represent the pinnacle of sliding door technology and design. They’re ideal for architectural projects, large-scale renovations, or anywhere that requires exceptional quality and performance. The large glass panels in these systems flood your living space with natural light and create truly impressive openings to your garden or patio area.
Installation Costs
The prices discussed above typically include standard installation, but certain factors can affect installation costs:
- Structural changes needed to accommodate the doors
- Complex access issues at your property
- Removal and disposal of old doors or windows
At North East Bifolds, our experienced installation team handles projects of all sizes across the North East. We take care to assess any potential challenges during the quotation process so you’ll have a clear understanding of the full cost before work begins.
Customisation Options
Colour Choices
Aluminium sliding doors can be finished in virtually any colour, allowing them to match or contrast with your home’s existing features. At North East Bifolds, we offer:
- Standard colours like white, black, and anthracite grey
- The full range of RAL colours for precise matching
- Dual colour options (different colours inside and out)
While standard colours are usually included in the base price, custom colours and dual colour options typically add to the cost.
Internal Blinds
For homeowners looking for additional privacy and light control, internal blinds are a popular choice. These blinds are housed within the glazing units of your sliding doors, providing a neat and protected solution.
Adding internal blinds will increase the overall cost of your sliding doors, but they offer practical benefits that many homeowners find worthwhile.
The Long-Term Value of Aluminium Sliding Doors
While the initial cost of aluminium sliding doors is higher than uPVC alternatives, they offer excellent long-term value for several reasons:
Durability and Lifespan
Aluminium doors can last up to 45 years with minimal maintenance, compared to 20-30 years for uPVC. This longer lifespan means the higher initial investment is spread over many more years of use.
The material stands the test of time, resisting corrosion, warping, and fading. In coastal areas, salt air can damage other materials, whereas properly finished aluminium remains robust and reliable.
Energy Efficiency
High quality aluminium sliding doors with thermal breaks and thick double glazing can offer excellent energy efficiency. By reducing heat loss in the winter, they can help lower your energy bills year after year.
Added Value to Your Property
Well-designed, high quality sliding doors can add value to your home. The appeal of bright, open living spaces with easy access to gardens or patios is a strong selling point for potential buyers.
The durability and low maintenance of aluminium also appeal to future homeowners, who won’t need to worry about replacing their doors for decades. This added value can offset at least some of the initial investment.
