At-a-glance pricing benchmarks in Gauteng – aluminium window prices
We offer clear, on‑site quotations across Gauteng so you know the full cost before work starts.
Typical unit benchmarks: Standard aluminium windows commonly sit between R1,500 and R5,000 per unit. Standard hinged or sliding doors usually start at about R3,000 and can exceed R15,000 for large or high‑spec panels.
Several key factors drive this range. Size and design raise material use and labour. Upgrades such as double glazing, thicker glass or specialist hardware add cost but improve comfort and security.
| Item | Typical range | Primary drivers |
|---|---|---|
| Standard windows | R1,500 – R5,000 | Size, frame profile, glazing |
| Aluminium doors | R3,000 – R15,000+ | Panels, hardware, glazing |
| Installation allowance | Quoted per job | Access, removals, structural work |
| Optional extras | Variable | Blinds, finishes, security features |
We itemise product, labour and any ancillary works so you see how each element affects the final price. Our onsite assessment refines these benchmarks into a precise proposal for your property.
aluminium window prices: key factors that influence the final cost
Several practical factors determine the final figure you will pay, and we explain each one clearly.
Size and configuration: from standard to oversized spans
Large spans and multi-panel arrangements use more material and often need extra labour or lifting gear.
Standard sizes are cheaper; bespoke dimensions add cutting, reinforcement and longer installation time.
Design and additional features: hardware, colours and specialised finishes
Simple casements cost less than custom shapes or complex mullion layouts.
Upgraded hardware, security fittings, insect screens or special colours increase unit cost but add value.
Glass specification: thickness, double glazing and thermal breaks for efficiency
Thicker panes, laminated safety glass or double glazing raise price but improve comfort and safety.
Thermal break frames give better efficiency and a higher frame cost, but reduce running costs over time.
Installation complexity and site conditions
Removal of old frames, plaster repairs, scaffold or high‑level access all add labour and time.
We assess structural changes and permit requirements so there are no surprises on the final quote.
Location and logistics across Gauteng
Traffic, parking, building access and delivery routes affect timelines and transport costs for projects in Midrand, Centurion and beyond.
We identify every cost driver during our onsite assessment so the quotation reflects real‑world requirements and site conditions.
Common aluminium window sizes in South Africa and how they affect price – aluminium window prices
Knowing standard module sizes helps you choose cost‑effective options and avoids unnecessary cutting.
Typical sliding units range from about 900 mm to 2,100 mm wide and 600–1,500 mm high. Wider sliders need stronger framing and more glass, so they raise the material and labour element of any quote.
Casement and awning openings are usually 500–1,000 mm wide and 600–1,800 mm high (awnings often sit 600–1,200 mm wide by 600–900 mm high). More sashes or heavier hardware increases complexity and cost.
Single and double‑hung frames commonly sit between 600 and 1,200 mm wide and 900–1,800 mm high. Balance mechanisms and safety glass options can nudge the budget higher for high‑use areas.
Fixed panes and shaped units need bespoke cuts. We use a PT series matrix (PT66 to PT2418) to show how small width/height steps alter cost. We measure onsite and advise when standard modules save budget and when custom sizes give a cleaner finish. All glazing is to SANS 10400 Part N; we recommend laminated or safety glass for bathrooms and near‑floor placements.
| Type | Typical W (mm) | Typical H (mm) |
|---|---|---|
| Sliding | 900–2100 | 600–1500 |
| Casement / Awning | 500–1200 | 600–1800 |
| Hung | 600–1200 | 900–1800 |
Finishes, glazing and energy efficiency for peace of mind – aluminium window prices
Selecting the right frame finish and glass can transform comfort, privacy and the look of any room.
We supply a full palette of frame finishes so your openings match façades and interiors. Popular choices are Bronze, White, Black, Natural Silver and Charcoal. We explain anodised versus powder‑coated options and advise where each performs best.
Glass choices and compliance
Choose clear glass for maximum daylight or obscure glass for privacy in bathrooms. All glazing is completed to SANS 10400 Part N for safety and compliance.
Energy upgrades that make a difference
Double glazing reduces heat gain and loss, improves acoustic comfort and helps stabilise indoor temperatures.
Thermal break frames limit heat transfer through the frame and reduce morning condensation. These upgrades improve long‑term comfort and add value.
| Feature | Benefit | Where to use |
|---|---|---|
| Bronze / Charcoal finishes | Strong aesthetic, hides dirt | Façades and modern interiors |
| Powder‑coated vs anodised | Durability vs low maintenance | Coastal or high‑sun exposure |
| Double glazing / Thermal break | Improved efficiency & comfort | Living rooms, bedrooms, noisy streets |
| Obscure glass / laminated | Privacy / safety | Bathrooms, near‑floor glazing |
We coordinate finishes across your aluminium windows doors package, prioritise quality seals and hardware, and confirm lead times so you have peace of mind from order to installation.

What to budget for installation and maintenance over the long term – aluminium window prices
A clear budget for fitting and future care helps you compare options by lifecycle value, not just sticker cost.
We set realistic expectations for installation cost by checking how many units you need, floor levels and access. Complex openings or structural changes increase labour and may extend the schedule.
Durability and low maintenance: The material resists rust and warping, so upkeep is minimal compared with timber. Small routine tasks keep performance high and save money long term.
Typical timelines and where to invest
Simple replacements can finish in a few days. Larger schedules or whole-property works can take one to two weeks or more depending on scope.
- Double glazing and thermal breaks raise upfront cost but cut heating and cooling spend over time.
- Quality gaskets, drainage channels and stainless fixings extend service life.
- Periodic washing and light oiling of hardware keeps moving parts working smoothly.
We plan deliveries, waste removal and finishing to minimise disruption. Warranties and aftercare information are included so you have peace of mind about workmanship and components.
| Item | Typical impact | Why it matters |
|---|---|---|
| Number of units | Directly affects labour & time | More units = longer programme, better bulk pricing |
| Access & floor level | May need scaffolding or lifts | Affects safety, labour hours and permits |
| Energy upgrades | Higher initial cost | Lower running costs and improved comfort |
| Maintenance needs | Low (periodic cleaning & lubrication) | Reduces long-term repairs and repainting |
