💰 Average Aluminium French Door Costs in South Africa
Here’s what you can expect to pay for aluminium french door cost across different quality tiers. French doors are typically more expensive than standard single doors but more affordable than sliding or bifold systems.
| Quality Tier | Per Door (Supply) | Double Door Total (Supply) | Glass Type | Hardware | Best For |

📊 French vs Sliding vs Bifold – Cost Comparison
Understanding how french door price compares to alternatives helps you make an informed decision.
| Door Type | Typical Width | Cost Installed | Opening % | Best For |
|---|---|---|---|---|
| Standard Single Door | 900mm | R8,000 – R15,000 | 100% (opens fully) | Standard entrances |
| French Doors (Double) | 1.8m – 2.4m | R15,000 – R30,000 | 100% (both open) | Patios, garden access, elegant entrances |
| Sliding Doors | 1.8m – 6.0m | R20,000 – R50,000 | 50% | Wide openings, limited wall space |
| Bifold Doors | 2.4m – 6.0m+ | R40,000 – R100,000+ | 95-100% | Maximum opening, stunning views |
Key insight: French doors offer the best value for openings up to 2.4m wide. They open 100% (both doors swing open), cost less than sliding doors of equivalent width, and offer unmatched elegance. For wider openings (3m+), sliding or stacking doors become more practical.
For a detailed comparison, read our aluminium vs steel comparison and brand quality guide.
🪟 How Glass Type Affects Aluminium French Door Cost
French doors are predominantly glass – often 70-80% of the door surface. Your glass choice dramatically impacts both price and performance.
| Glass Type | Cost Premium (per door) | Energy Savings | Noise Reduction | Double Door Cost Impact | Best For |
|---|---|---|---|---|---|
| 4mm Single (Standard) | Included | Poor | Poor | R0 | Budget projects, covered patios |
| 5mm Single Glaze | +R200 – R350 | Fair | Fair | +R400 – R700 | Standard homes, better security |
| Double Glazing (4+4mm) | +R900 – R1,600 | Excellent (40-60%) | Excellent | +R1,800 – R3,200 | Energy efficiency, noisy areas |
| Low-E Coated | +R500 – R900 | Excellent | Good | +R1,000 – R1,800 | Sun-facing doors, heat reduction |
| Laminated Safety Glass | +R400 – R800 | Good | Very Good | +R800 – R1,600 | Security, impact resistance |
For a double French door set (approximately 2.5-3m² of glass), upgrading from 4mm to double glazing adds R1,800 – R3,200 to your aluminium french door cost. This often pays back in energy savings within 3-5 years.
🔧 How Hardware Quality Impacts French Door Price
The hardware on French doors is critical for security and smooth operation. Here’s what affects double door cost.
Hardware Components and Cost Differences:
- Hinges: Standard steel hinges cost R200-400 per door. Stainless steel hinges cost R500-800 – essential for coastal areas.
- Handles: Basic handles cost R200-400. Designer stainless steel handles cost R800-1,500.
- Locks and security: Single-point lock (R300-500) vs multi-point locking system (R1,200-2,500). Multi-point hooks into the frame at 3-5 points for security.
- Shoot bolts (top and bottom): Additional locking points on the inactive door – add R400-800 per door.
- Door closers: For commercial or heavy-use applications – add R500-1,200.
🎁 Pro Tip: Invest in Multi-Point Locks for Security
French doors are beautiful but can be a security weak point if not properly locked. Spend the extra R1,000-2,000 on multi-point locking systems. For coastal areas like Cape Town, stainless steel hardware is essential – standard steel corrodes within 2-3 years. Read our buying checklist for more security tips.
🛠️ Installation Costs – What to Expect
French door installation is straightforward but requires precision. Here’s what affects french door pricing for installation.
Typical Installation Costs Breakdown:
- Basic installation (new builds): R3,000 – R5,000 for double doors – fitting into prepared opening
- Retrofit installation (replacement): R5,000 – R8,000 for double doors – includes old door removal, opening adjustments
- Structural work: If lintel reinforcement or wall modification needed, add R3,000 – R10,000
- Floor levelling: If floors are uneven, French doors won’t close properly – add R1,500 – R4,000 if needed
Why professional installation matters:
- Frames must be perfectly square – French doors won’t close properly if frames are out of alignment
- Threshold must be level – gaps cause air and water leaks
- Weather sealing must be perfect – French doors are more exposed to the elements than other door types
- Security hardware must be correctly installed – misaligned locks don’t secure properly

📐 Configuration Options – Single, Double, Sidelites
French doors come in several configurations, each affecting double door cost differently.
Single French Door:
- One door with frame – can open inward or outward
- Cost: R6,000 – R12,000 installed
- Best for: Side entrances, smaller openings
Double French Doors (Standard):
- Two doors side by side – both can open (or one fixed, one active)

- Most common for patios and garden access
- Best for: Openings 1.5m – 2.4m wide
French Doors with Sidelites:
- Double doors with narrow fixed glass panels on one or both sides
- Cost: Add R4,000 – R10,000 per sidelite
- Creates a grand entrance with more natural light
- Best for: Front entrances, luxury applications
French Doors with Transom (Top Window):
- Doors with a fixed glass panel above
- Cost: Add R3,000 – R8,000 for transom
- Adds height and drama to the entrance

For standard residential applications, double French doors offer the best value. For custom configurations, consult our custom fabrication guide.

🌳 Aluminium vs Wood French Doors – Maintenance & Longevity
Many homeowners ask me about wood vs aluminium French doors. Here’s the honest comparison.
Aluminium French Doors:
- No warping, rotting, or swelling – stable in all weather
- Virtually maintenance-free – just occasional cleaning
- Powder-coated finish lasts 15-20+ years without fading
- Thermal break options available for energy efficiency
- Cost: R15,000 – R30,000 for double doors installed
- Lifespan: 30-50 years
Timber/Wood French Doors:
- Beautiful natural appearance – cannot be replicated perfectly in aluminium
- Requires sanding, painting, or varnishing every 2-5 years
- Can warp, rot, or be damaged by termites
- Less energy efficient unless specialised
- Cost: R25,000 – R50,000+ for quality timber double doors
- Lifespan: 15-25 years with diligent maintenance
My honest advice: If you love the natural look of wood and don’t mind maintenance, timber French doors are beautiful. But for most homeowners, aluminium offers better value – lower upfront cost, zero maintenance, and longer lifespan. Modern powder coating can mimic wood grain finishes if you want the timber look without the work.

❓ Frequently Asked Questions About Aluminium French Door Costs
How much do aluminium french doors cost for a standard double door set?
For a standard double aluminium french door cost (2 x 900mm doors), expect R10,000 – R16,000 supply only, or R13,500 – R21,500 installed. Premium versions with double glazing and multi-point locks cost R17,000 – R27,000+ installed. For coastal areas like Cape Town, add 10-15% for marine-grade stainless steel hardware.
Are aluminium French doors more expensive than wood?
No – french door price for aluminium is typically 30-50% less than quality timber French doors. A standard double aluminium French door costs R13,500 – R21,500 installed vs R25,000 – R50,000+ for timber. Aluminium also requires virtually no maintenance (no sanding, painting, or sealing), making it more cost-effective over time. Read our comparison guide for more.
What affects aluminium french door cost the most?
The biggest factors in how much do aluminium french doors cost are: size (larger doors cost more), glass type (double glazing adds R900-1,600 per door), hardware quality (multi-point locks add R1,200-2,500), and powder coating colour (custom colours add 20-35%). Coastal-grade protection adds 10-15%. Always get detailed quotes breaking down these components.
Can French doors be installed in existing openings?
Yes – retrofit installation is common. Expect to pay R5,000 – R8,000 for double door installation, which includes old door removal and opening adjustments. If your opening isn’t standard size (1.8m, 2.0m, or 2.4m wide), custom sizing adds 15-30% to fabrication costs. Have a fabricator measure your opening before ordering – custom sizes take 2-4 weeks lead time.
Are aluminium French doors energy efficient?
Standard single-glazed aluminium French doors have poor energy efficiency – aluminium conducts heat/cold easily. However, thermal break profiles (polyamide strip between inner and outer frames) and double glazing dramatically improve performance. A thermal break + double glazed French door can achieve 40-60% energy savings compared to standard versions. For energy-conscious homeowners, the upgrade is worth the additional double door cost.
How long do aluminium French doors last?
Quality aluminium french doors last 30-50 years. The aluminium frames themselves last 50+ years. Hardware is the component that may need replacement – standard steel hardware lasts 5-10 years, while stainless steel hardware lasts 15-25+ years. For coastal areas, stainless steel is essential to prevent corrosion. Powder-coated finishes last 15-20+ years without fading or chipping.
Do aluminium French doors need maintenance?
Virtually none – this is one of the biggest advantages over wood. Just occasional cleaning with mild soap and water. Lubricate hinges and locks annually with silicone spray. Powder-coated finishes don’t need painting or sealing. Compare this to timber French doors which need sanding, painting, or varnishing every 2-5 years – the maintenance savings alone often justify the aluminium french door cost.
How can I get the best french door price in South Africa?
To get the best french door price: 1) Get quotes from at least 3 fabricators via ServiceLink SA’s free service. 2) Choose standard sizes (900mm wide per door). 3) Stick to standard colours (white or silver). 4) Consider mid-range hardware – the sweet spot for value. 5) Use our Beat Your Quote guarantee. 6) Install during off-peak season. 7) For coastal areas, invest in marine-grade – cheap coastal doors fail quickly.
✅ Final Thoughts: French Doors – Timeless Elegance at an Affordable Price
Understanding aluminium french door cost reveals why these doors remain one of the most popular choices for South African homeowners.
French doors offer the perfect balance: elegant design that suits any architectural style, 100% opening (both doors swing open), energy efficiency when properly specified, and significantly lower cost than bifold or wide sliding systems. For openings up to 2.4m wide, French doors are often the smartest choice.
