Sliding glass doors are a stunning addition to any home, creating a seamless connection between indoor and outdoor spaces.
They allow natural light to flood your home while providing easy access to gardens, patios, or balconies.
Whether you are looking to enhance your home’s aesthetic appeal, increase functionality, or improve energy efficiency, sliding glass doors are a worthwhile investment.
But how much do they cost? The price of sliding glass doors can vary significantly based on factors like material, size, customization options, and installation fees.
Homeowners often find themselves weighing different options to strike the right balance between cost and quality.
This guide will break down everything you need to know about sliding door costs, from base prices to additional expenses, helping you make an informed decision that fits your budget and style preferences.
3 Factors That Affect Sliding Door Cost
1. Material
The material of your sliding glass door is one of the biggest factors influencing cost. Here are the most common materials and their price ranges:
- uPVC: The most budget-friendly option, typically ranging from £400 to £800 for a standard-sized door.
- Aluminium: A sleek, durable, and modern choice, aluminium sliding doors start at around £1,500 and can go beyond £4,000 depending on design and size.
- Timber: Offering a natural aesthetic, timber sliding doors can cost anywhere from £2,000 to £5,000+ depending on the wood type and finish.
2. Size
The larger the sliding glass door, the higher the cost. Standard two-panel doors are more affordable, while wider openings with three or four panels increase the price due to additional materials and complexity in installation. Custom-sized doors can add another 20-50% to the overall cost.
3. Customization Options
Features like energy-efficient glazing, slimline frames, integrated blinds, and premium hardware can raise the price significantly. For example:
- Triple glazing: Adds approximately 20% to the cost compared to double glazing.
- Integrated blinds: Can add £500-£1,000 depending on the mechanism and style.
- Bespoke frame finishes: Choosing custom colours or woodgrain effects increases costs by around 10-30%.
Average Cost of Sliding Doors: What to Expect
A standard sliding glass door (two-panel uPVC) can cost as little as £400-£800 supply-only, whereas high-end aluminium doors like Smart Aluminium Sliding Doors or Korniche Cortizo 4700 can cost upwards of £2,000, especially for larger configurations.
For homeowners looking at premium options, ultra-slim sliding doors like the Cortizo Cor Vision can cost anywhere between £4,000-£6,000, depending on specifications.
Additional Costs to Consider
Installation Fees
The cost to install a sliding patio door varies based on labour rates, door size, and complexity. Typical installation fees range from £500 to £2,500. If structural modifications are required, expect higher costs.
Hardware and Accessories
Handles, locks, and threshold options can also impact price:
- Standard hardware: Included in most door prices
- Premium handles & locks: £50-£200 extra
- Low threshold accessibility options: £200-£500
Structural Modifications
- Widening an opening: If a larger door is needed, structural reinforcements can cost an additional £1,000-£3,000.
- Lintel installation: Required for larger doors, typically costing £500-£1,500.
- Permits and inspections: Depending on local regulations, you may need permits costing £100-£300.
Budgeting for Sliding Doors: How to Save
- Compare different materials: Aluminium offers better longevity and aesthetics than uPVC but at a higher price.
- Opt for supply-only: If you have installation expertise, purchasing a door without fitting can save you hundreds.
- Look for seasonal deals: Many suppliers offer discounts during off-peak seasons.
- Consider standard sizes: Custom doors are more expensive, so sticking to standard dimensions helps keep costs down.
- Work with local installers: Local professionals often offer more competitive pricing than national companies.
- Plan for long-term efficiency: Investing in energy-efficient glazing may have higher upfront costs but will save money on heating bills over time.
Choosing the Right Sliding Door for Your Home
When choosing a sliding door, consider:
- Your home’s aesthetic: Modern aluminium doors suit contemporary homes, while timber works well in traditional settings.
- Glass options: Energy-efficient, self-cleaning, or noise-reducing glass can enhance performance.
- Space availability: If space is limited, sliding doors are a better option than bifold doors.
