Aluminium Security Doors Cost & Installation: Complete Guide for SA Homeowners
🚪 The complete guide to pricing, types, and installation of security doors for your home
Let me share something I’ve learned after helping hundreds of homeowners across Gauteng, Johannesburg, and Pretoria secure their homes. A security door is one of the best investments you can make. It lets you keep your main door open for ventilation while keeping intruders out. It adds a visible deterrent that says “this home is protected.”
But here’s the challenge. Aluminium security doors cost varies enormously – from R3,000 for a basic fixed screen door to R12,000+ for a premium expandable mesh door. And that’s just the supply cost. Installation adds another R1,000-3,000. Understanding what drives these prices is essential for budgeting.
In this complete security door installation guide, I’ll answer how much do aluminium security doors cost, compare different types (expandable mesh, fixed mesh, bar doors), break down costs by size and specification, explain professional installation requirements, and help you choose the right burglar door price for your home.

🛡️ Why You Need a Security Door
A security door is more than just an extra lock – it’s a complete security solution.
Key benefits of security doors:
- Ventilation with security: Leave your main door open while keeping intruders out. Essential for hot South African summers.
- Visible deterrent: Security doors signal that your home is protected. Burglars often move on to easier targets.
- Layered security: Even if someone picks your main door lock, they still face a second barrier.
- Child safety: Stops small children from wandering outside unsupervised.
- Dog/kid friendly: Keeps pets and children inside while allowing airflow.
- Insurance benefits: Many insurers offer premium discounts for approved security doors.
According to SAPS security recommendations and SANS 10400 security door standards, security doors are recommended for all ground floor entrances.
🎁 Pro Tip: The 24/7 Advantage
A major benefit of aluminium security doors is you can leave your main door open all day for fresh air. In our climate, that’s a game-changer. You get the breeze without security worries. For Johannesburg and Pretoria summers, this alone justifies the cost.
🚪 Types of Aluminium Security Doors
Understanding the different types helps you compare security screen doors pricing.
Fixed mesh security doors (economy):
- Rigid aluminium frame with fixed mesh screen
- Mesh is welded or clipped to the frame (doesn’t move)
- Affordable, good ventilation, basic security
- Not as strong as expandable mesh
- Cost: R3,000 – R6,000 supply only
Expandable mesh security doors (popular):
- Mesh expands like an accordion when door is opened
- Stronger than fixed mesh – hardened steel or aluminium mesh
- Trellidor is the most recognised brand (but expensive)
- Excellent security, good ventilation, smooth operation
- Cost: R5,000 – R12,000+ supply only
Bar-type security doors:
- Vertical or horizontal bars (not mesh)
- Strongest option – bars are difficult to cut
- Limited ventilation – large gaps between bars
- Not suitable for areas with small children (heads could fit through bars)
- Cost: R4,000 – R8,000 supply only
Security gate (internal):
- Installed inside the home (e.g., at top of stairs)
- Keeps children or pets contained while allowing airflow
- Lighter construction than external doors
- Cost: R2,000 – R5,000

Size impact: Taller doors (e.g., 2200mm or 2400mm height) add 10-25% to cost. Custom sizes add 15-30%.
🗺️ Aluminium Security Door Prices by Province
Aluminium security doors cost varies by province due to labour rates and competition.
| Province/City | Fixed Mesh (Installed) | Expandable Mesh (Installed) | Notes |
|---|---|---|---|
| Gauteng | R4,500 – R7,500 | R6,500 – R10,000 | Most competitive, many suppliers |
| Johannesburg | R4,200 – R7,200 | R6,200 – R9,800 | Best prices in Gauteng |
| Pretoria | R4,500 – R7,800 | R6,500 – R10,200 | Slightly higher than Johannesburg |
| Sandton | R5,000 – R8,500 | R7,000 – R12,000 | Premium area, higher labour rates |
| Centurion | R4,600 – R8,000 | R6,800 – R10,500 | Similar to Pretoria |
In Gauteng, Johannesburg offers the most competitive security door installation pricing due to many suppliers. For Sandton, expect to pay a premium for labour.
📊 Aluminium vs Trellidor vs Steel – Comparison
The classic debate: which security door offers the best value? Here’s an honest comparison.
| Feature | Aluminium Fixed Mesh | Aluminium Expandable Mesh | Trellidor (Brand) | Steel Bar Door |
|---|---|---|---|---|
| Cost (single, installed) | R4,000 – R8,000 | R6,500 – R10,500 | R10,000 – R15,000+ | R5,200 – R10,500 |
| Security level | Good | Excellent | Excellent | Excellent (but bars can be spread) |
| Ventilation | Excellent | Excellent | Excellent | Poor (bar spacing limits airflow) |
| Child safety | Good (small mesh) | Excellent (small holes when closed) | Excellent | Poor (bars too wide) |
| Corrosion resistance | Good (powder coated) | Good | Good | Poor (rusts in coastal areas) |
| Brand premium | Low | Medium | High | Low |
My recommendation: For most homes, a quality aluminium expandable mesh door (not necessarily Trellidor) offers the best balance of security, ventilation, and cost (R6,500-10,500 installed). Trellidor is excellent but you pay a significant brand premium. Steel bar doors are strong but poor for child safety and ventilation.

🛠️ Security Door Installation – What’s Involved
Professional security door installation ensures proper fit and security. Here’s what’s involved.
Step 1: Site survey and measurement
- Installer measures the door opening
- Checks for square and level
- Assesses wall type (brick, concrete, timber)
Step 2: Door preparation (if not pre-assembled)
- Frame assembly
- Mesh or bar fitting
- Hinge and lock installation
Step 3: Frame fixing
- Frame positioned and levelled
- Secured with appropriate fixings (expanding bolts for brick/concrete)
- Typically 6-8 fixing points per frame
Step 4: Door hanging
- Door attached to frame with security hinges
- Alignment checked and adjusted
- Lock mechanism tested
Step 5: Finishing
- Gaps filled with sealant
- Hardware adjusted for smooth operation
- Cleanup and testing
Installation time: 2-4 hours for a standard single door.
Key to quality installation: The frame must be perfectly level and square. A misaligned frame will cause the door to stick, not close properly, or create gaps that compromise security. Use certified installers only.
🔒 Lock Options & Security Features
The lock is the heart of any security door. Here are your options.
Lock types (from basic to most secure):
- Basic latch (standard): Simple spring latch. Minimal security. Not recommended.
- Keyed cylinder lock (good): Standard key lock – provides reasonable security. Cost included in most doors.
- Deadbolt (better): Separate deadbolt above the handle. Much harder to force. Adds R300-600.
- Multi-point locking (best): One key turn operates 2-3 locking points (top, centre, bottom). Excellent security. Adds R800-1,500.
- Smart lock (premium): Keypad or fingerprint access. Can be integrated with home automation. Adds R1,500-4,000.
Security hinges: Security doors should have hinges with non-removable pins. Standard hinges are a weak point – the door can be lifted off. Security hinges add R200-500.
Recommendation: For external security doors, specify multi-point locking and security hinges. The extra cost (R1,000-2,000) is worth the peace of mind.
Read our locks guide for detailed specifications.
⚠️ Hidden Costs to Watch Out For
⚠️ Warning: These Hidden Costs Inflate Your Security Door Price
Always ask for a detailed breakdown when comparing aluminium security doors cost quotes.
- Installation not included: Many quotes are supply-only. Installation adds R1,000-3,000.
- Removal of old door: If replacing an existing security door, removal fees add R200-500.
- On-site modifications: If the opening isn’t square, preparation work adds R500-1,500.
- Custom colours (powder coating): Standard white or silver included. Custom colours add 20-35%.
- Non-standard sizes: Custom-sized doors add 15-30% to fabrication costs.
- Lock upgrades: Basic locks are included; multi-point locks add R800-1,500.
- Security hinges: Standard hinges included; security hinges add R200-500.
- Door closer: If you want an automatic closer, add R300-800.
- VAT: Some quotes exclude VAT (15%). Always confirm.

🌊 Coastal Considerations – Marine Grade
In coastal areas, standard security doors can corrode quickly.
The problem: Salt spray corrodes standard aluminium and steel. Within 5km of the ocean, standard security doors may show corrosion within 2-3 years.
Solutions for coastal homes:
- Marine-grade powder coating: Thicker, more durable coating. Standard powder coating is 40-60 microns; marine-grade is 80-120 microns. Add 10-15% to cost.
- Stainless steel hardware: All hinges, locks, and screws must be stainless steel (Grade 304 or 316). Standard steel corrodes rapidly. Add 15-25%.
- Aluminium mesh (not steel): For expandable doors, specify aluminium mesh rather than steel.
- Sealed bearings in hinges: Prevents salt ingress.
Recommendation: If you live within 5km of the coast (e.g., Cape Town, Durban, Port Elizabeth), specify marine-grade for your security door. The 20-40% premium is worth it for 10-15+ years of life vs 2-5 years for standard.

🧹 Aluminium Security Door Maintenance & Care
Proper maintenance extends the life of your security screen doors.
Quarterly maintenance:
- Clean mesh/screen with a soft brush and mild soap
- Wipe frames with a damp cloth
- Remove debris from hinges and lock mechanism
- Lubricate hinges and lock with silicone spray (never oil)
Annually:
- Inspect all screws – tighten if loose
- Check weather seals (if installed) – replace if cracked
- Check that the door closes and locks smoothly
- For coastal areas, check for early signs of corrosion
What not to do:
- Never use abrasive cleaners – they scratch powder coating
- Never use oil-based lubricants – they attract dust
- Never force a sticking door – adjust hinges instead

❓ Frequently Asked Questions About Aluminium Security Doors
How much does an aluminium security door cost in South Africa?
Aluminium security doors cost ranges from R4,000-8,000 for a fixed mesh door installed, R6,500-10,500 for a standard expandable mesh door, and R10,000-15,000+ for premium branded doors like Trellidor. Prices are for standard single doors (900mm x 2100mm). Double doors cost 1.5-2x more. Read our price guide for detailed breakdowns.
What is the difference between Trellidor and aluminium security doors?
Trellidor is a specific brand of expandable mesh security door – it’s aluminium, but with a strong brand reputation and premium pricing. Generic aluminium expandable mesh doors offer similar functionality for 30-40% less. Both offer excellent security. Trellidor’s main advantages are brand recognition, warranty, and sometimes better after-sales support. Read our full comparison.
How much does security door installation cost?
Security door installation labour costs R1,000-3,000 for a standard single door. This includes site survey, fitting, levelling, fixing, and testing. Some companies include installation in the quoted price; others quote supply only. Always clarify. DIY installation is not recommended – incorrect fitting compromises security.
Are aluminium security doors strong enough?
Yes – quality aluminium security doors are very strong. The frame is typically 1.5-2mm thick aluminium. The mesh (if expandable) is hardened steel or aluminium that resists cutting. A properly installed aluminium security door with multi-point locking is extremely difficult to breach. For maximum strength, bar-type doors are even stronger but offer less ventilation.
Do I need a security door on every entrance?
At minimum, secure your main entrance (front door), back door, and any side doors. Sliding doors also need security – either a security door installed over the sliding door or security bars/gate on the sliding door itself. Read our security features guide for a full assessment.
Will a security door affect my home insurance?
Yes – many insurers offer premium discounts (5-15%) for homes with approved security doors. Check with your insurer before purchasing – they often have approved supplier lists and specifications. Keep proof of installation for insurance records. The discount often pays for the security door over a few years.
How do I maintain my security door?
Maintenance is minimal: quarterly cleaning of mesh and frames with mild soap and water, annual lubrication of hinges and locks with silicone spray, and checking for loose screws. For coastal areas, inspect for corrosion every 3 months. Never use oil-based lubricants – they attract dust.
How do I find a reliable security door installer?
Use ServiceLink SA’s free quote service to find verified security door specialists. Look for: verified contractors, customer reviews, experience with your chosen door type, transparent pricing, and workmanship guarantees. For Gauteng, Johannesburg, Pretoria, Sandton, or Centurion, ask for local references.
✅ Final Thoughts: A Security Door Is Peace of Mind
After reading this aluminium security doors cost guide, you understand that a security door is one of the best investments you can make for your home.
Yes, R4,000-15,000 is real money. But compare that to the cost of a burglary – stolen goods, damaged property, trauma, insurance claims. A security door is a one-time investment that protects your family and belongings for 10-20+ years.
For most homes, a standard expandable mesh aluminium security door (R6,500-10,500 installed) offers the best value. You get excellent security, great ventilation, and a professional appearance. Upgrade to multi-point locks and security hinges for an extra R1,000-2,000 – money well spent.
Don’t wait until after a break-in to secure your home. The best time to install a security door is today.
