Aluminium Door Prices in South Africa — 2026 Complete Guide
Aluminium doors are taking over South African homes — and for good reason. They don't rust, don't warp, and don't need repainting every two years like wooden doors. Aluminium door prices in South Africa range from R3,000–R14,000 for standard entrance doors to R18,000–R20,000 per leaf for folding doors. For aluminium sliding doors, expect R8,000–R20,000. This guide covers every type of aluminium door, what you should pay, and how to avoid overpaying.

Aluminium doors are the smart choice for coastal homes — Cape Town's salt air destroys wooden doors within 5 years — but they're also gaining popularity nationwide for their clean modern look, zero maintenance, and superior durability. Here's the full breakdown of what you'll actually pay in 2026.
Aluminium Door Prices at a Glance
| Door Type | Price Range (Installed) | Notes |
|---|---|---|
| Aluminium entrance / front door | R3,000 – R14,000 | Without frame R3K+, with frame R8K–R14K |
| Aluminium interior door | R2,500 – R7,500 | Similar to hardwood pricing, but zero maintenance |
| Aluminium sliding door (standard) | R8,000 – R20,000 | Includes frame and track, 1,800mm–3,000mm opening |
| Aluminium folding/stacker door | R18,000 – R20,000/leaf | Premium product, needs steel lintel above |
| Aluminium door frame | R2,000 – R6,000 | Frame only, no door leaf |
| Aluminium door installation labour | R1,500 – R3,500 | Per door, replacement in existing opening |
Why Aluminium is Beating Wood in SA (Especially in Cape Town)
The simple reason: salt air. In Cape Town, Durban, PE, and any home within 15km of the coast, wooden doors absorb moisture, swell, rot, and attract wood-boring insects. You'll repaint a wooden front door every 12–18 months in these areas. Aluminium doesn't rust (it oxidises — a thin protective layer forms naturally), doesn't rot, and powder coating lasts 10–15 years without fading. Even in Gauteng, where humidity is lower, aluminium doors are chosen for their clean lines, slim profiles, and the fact that you install them once and forget about them.
Entrance Doors vs Interior Doors — Price Difference Explained
An aluminium entrance or front door costs R3,000–R14,000 — the wide range depends on size, glass, and whether the frame is included. Interior aluminium doors are cheaper at R2,500–R7,500 because they don't need weather sealing, high-security locking, or the same structural strength. If you're replacing an entire house, expect interior doors at R2,500–R7,500 each and the front door at R8,000–R14,000 with frame and high-security lock.
Aluminium Folding Doors — The Premium Option
Aluminium folding doors (also called stacker or bi-fold doors) are running at R18,000–R20,000 per leaf in 2026. A 4-leaf opening covering 3.6m costs R72,000–R80,000 before installation. These doors are becoming standard in new builds and high-end renovations in Cape Town, Johannesburg, and the Winelands. The cost is justified by the engineering — each leaf needs precision hinges, heavy-duty tracks, and multi-point locking. A steel or reinforced concrete lintel above the opening is mandatory and costs R3,000–R8,000 extra if not already in place.
Security Comparison — What Locking System Protects Your Home?
| Locking System | Security Level | Cost Extra | Recommendation |
|---|---|---|---|
| Single-point latch | Low — can be jimmied | Standard (included) | Not recommended for front doors or perimeter doors |
| 2-point locking (top + bottom) | Medium | R300–R800 | Minimum standard for all exterior aluminium doors |
| 3-point locking (top + middle + bottom) | High | R800–R2,000 | Recommended for front/entrance doors |
| Multi-point locking (5+ points) | Very high | R1,500–R3,500 | Best for high-crime areas and folding doors |
| Security hinges (anti-removal) | High | R200–R600 per hinge | Essential — prevents door being lifted off hinges |
The frame anchoring is just as important as the lock. A R3,000 multi-point lock in a frame held by 25mm screws is useless — the frame gets kicked in. Quality installations use 75mm–100mm screws into the brickwork or concrete surround, not just into the wooden door frame. For folding doors, each leaf should have its own locking point top and bottom. Ask your installer to show you the screw length they use for frame fixing.
Wood vs Aluminium — Total Cost Over 15 Years
| Cost Factor | Wooden Door | Aluminium Door |
|---|---|---|
| Upfront purchase (entrance door) | R3,100 – R14,000 | R3,000 – R14,000 |
| Repainting/refinishing (every 2 years) | R500 – R1,500 per time (7× over 15 years = R3,500–R10,500) | R0 – never needed |
| Rust/rot repairs | Likely in coastal areas (R1,000–R3,000 by year 8–10) | R0 — aluminium doesn't rust or rot |
| Warping replacement risk | Moderate — wooden doors can warp in humidity (replacement R3,000–R14,000) | None — aluminium maintains shape |
| 15-year total cost (coastal) | R10,000–R30,000+ | R3,000–R14,000 (one-time cost) |
The numbers are clear: aluminium costs the same or slightly more upfront, but over 15 years in a coastal area like Cape Town, aluminium works out 20–40% cheaper than wood. In Gauteng where humidity is lower and wooden doors last longer, the gap narrows to 10–20% — but aluminium still wins because you never have to paint, seal, or worry about wood-boring insects. In estate homes where HOA rules require a timber aesthetic, aluminium doors with wood-grain powder coating give you the look with none of the maintenance.
Colour and Finish Options — What Costs Extra
Standard powder coating colours (white, silver, bronze, charcoal, black) are included in the door price. Premium finishes cost more: wood-grain effect adds 10–15% (R500–R2,000 per door), anodised silver adds 10–20% (R300–R1,500 per door), and special RAL colours add 5–10% (R200–R1,000 per door). Wood-grain aluminium doors are increasingly popular in estates where HOA rules require a timber look — you get the aesthetic without the maintenance. Anodised finishes are popular in Cape Town coastal areas for their superior corrosion resistance. When getting quotes, ask for a colour chart and check what's included. Some contractors charge extra for any colour except white.
Frequently Asked Questions
Upfront, aluminium doors cost slightly more than comparable wooden doors — R3,000–R14,000 vs R3,100–R14,000 for wooden entrance doors. But aluminium wins on total cost of ownership: no painting or sealing every 2 years (saving R500–R1,500 per maintenance cycle), no rot replacement, and no warping. Over 15 years, aluminium works out 20–40% cheaper than wood, especially in coastal areas.
Aluminium doors with multi-point locking systems offer excellent security — as good or better than wooden doors. The aluminium extrusion itself is very strong, and modern aluminium doors come with security hinges (cannot be removed from the outside) and reinforced strike plates. For front doors, choose a door with at least a 3-point locking system and a quality brand lock (Yale, Era, or similar). The door frame also needs to be properly anchored into the wall — a strong door in a weak frame is just as bad as a weak door.
Standard powder coating colours include white, silver, bronze, charcoal, and black — these are usually included in the price. Premium finishes like wood-grain effect, anodised silver, or special RAL colours cost 10–20% more. The wood-grain effect is popular for estate applications where HOA rules require a timber look, and it's an excellent compromise between aesthetics and zero maintenance.
A standard aluminium door replacement takes 2–4 hours. A new opening takes 1–2 days including lintel installation, brickwork, and finishing. For a full house replacement (6–10 doors), expect 3–5 days. The aluminium doors themselves take 2–4 weeks for manufacturing (standard sizes are quicker, custom sizes take longer).
Replacing an existing door with an aluminium door in the same opening does NOT need building plans — it's a like-for-like replacement. Enlarging an opening, creating a new opening, or changing the structural opening does need approved plans. Check with your municipality and HOA before starting structural work.
Yes, many modern aluminium doors in South Africa now come with thermal break — a polyamide or plastic strip inserted between the interior and exterior aluminium profiles. This prevents heat from conducting through the metal frame, keeping your home cooler in summer and warmer in winter. Thermal break adds 10–15% to the door price (R500–R2,000 per door) and is worth it if your door faces the afternoon sun or you're in an area with significant temperature swings (Gauteng Highveld winters). Without thermal break, an aluminium door frame can get noticeably cold in winter and hot in summer. For folding doors with large glass areas, thermal break is strongly recommended.
Aluminium doors are the best choice for coastal South Africa — Cape Town, Durban, PE, and the Garden Route. Wooden doors in these areas absorb salt-laden moisture, swell, rot, and attract wood-boring insects within 5–8 years. Aluminium naturally forms a protective oxide layer that resists salt corrosion. However, not all aluminium doors are equal — ask for Chromadek or marine-grade finish for the best coastal performance. Standard powder coating is fine for 5–10km inland, but within 5km of the coast, the upgraded coastal-grade finish is worth the 10–15% premium. Avoid anodised finishes within 500m of the ocean — while corrosion-resistant, anodised surfaces can develop 'spotting' in direct coastal salt spray. Powder coating is the better choice for beachfront properties.
