The short answer
There is no honest one-price-fits-all answer for aluminium windows because every quote combines the frame, opening style, glass, finish, hardware, removal, and installation conditions.
The fastest way to get a useful price is to send clear photos, rough opening sizes, your suburb, and the number of windows you want to replace. That gives the installer enough information for an early estimate, while a site measure confirms the final manufacturing sizes and written quote.
If you are comparing aluminium windows in Krugersdorp, compare the full installed scope rather than the cheapest frame price.
What an aluminium window quote should include
A complete quote should make it clear whether the price includes measurement, manufacturing, glass, hardware, delivery, removal of old frames, installation, sealing, making good around the opening, disposal, and VAT.
Two quotes can look similar at the top and still describe very different jobs. One may be a supply-only frame price, while the other includes the complete removal and replacement.
Before comparing totals, compare these items line by line:
- The exact window style and number of opening sections.
- The aluminium profile or system specified for the opening.
- The frame colour and finish.
- The glass type and thickness.
- Locks, handles, stays, rollers, and restrictors.
- Removal and disposal of the existing window.
- Installation, perimeter sealing, and making good.
- The workmanship guarantee and any product warranties.
The seven factors that move the price
1. The size of the opening
A larger window uses more aluminium and glass, but size is not the only cost driver. A wide fixed pane can be simpler than a smaller window with several opening sections and more hardware.
That is why a price per square metre is only a rough comparison tool and not a final installed quote.
2. The window style
Fixed panes are usually the simplest configuration because they do not need hinges, stays, handles, or moving sashes.
Top-hung aluminium windows add controlled ventilation and are common in bathrooms, kitchens, and passages.
Sliding aluminium windows suit wider openings and rooms where an outward-opening sash would be inconvenient.
Combination windows cost more than a basic fixed pane because every opening section adds framing, hardware, manufacturing time, and adjustment during installation.
3. The glass specification
Clear float glass is not suitable for every opening. The required glass depends on the pane size, height, location, use of the room, and the safety risk around the opening.
Laminated safety glass, toughened glass, obscure glass, tinted glass, low-e glass, and double glazing all solve different problems and carry different costs.
The right question is not simply which glass is cheapest. It is which glass is appropriate for the opening and the result you want.
4. The frame colour and finish
White, charcoal, bronze, and black are common aluminium window colours, but availability and pricing depend on the selected system and finish.
A standard powder-coated colour is generally easier to source than a custom colour matched to an architect, estate, or existing frame schedule.
Confirm the colour in writing because black, charcoal, and bronze are not interchangeable once the frames are installed next to one another.
5. Steel or timber window removal
Replacing an old steel window is not the same as fitting a new frame into a prepared opening. The existing frame must be removed carefully, the opening cleaned and checked, and the new aluminium window fitted, levelled, fixed, sealed, and finished.
Wall condition also matters. Loose plaster, damaged sills, security bars, burglar proofing, tiles, blinds, or built-in finishes can change the labour needed around the opening.
Our guide to replacing steel windows with aluminium explains that process step by step.
6. Hardware and security
Handles, locks, friction stays, restrictors, and multi-point locking are part of how the window works every day.
Cheaper hardware can reduce the quote now and create stiff operation, rattles, or replacement costs later. A good quote identifies the hardware rather than hiding it inside a generic line such as “standard accessories.”
7. Access and site conditions
Ground-floor windows with clear access are simpler than upper-storey windows, tight side passages, windows over counters, or openings affected by scaffolding and security fixtures.
An installer should see those conditions before committing to the final price and programme.
How to compare two aluminium window quotes
Use this comparison instead of looking at the total alone:
| Compare | What to check |
|---|---|
| Scope | Supply only, or complete removal and installation |
| Window schedule | Sizes, styles, fixed sections, and opening sections |
| Aluminium | Profile or system suited to the opening |
| Glass | Type, thickness, tint, privacy, safety, and energy needs |
| Hardware | Locks, handles, stays, rollers, and restrictors |
| Finish | Exact colour and coating or anodised finish |
| Site work | Removal, disposal, sealing, and making good |
| Aftercare | Workmanship guarantee and product warranties |
A quote that leaves several of these blank is difficult to compare and easy to misunderstand.
Should you replace one window or the whole house?
Replacing one failed window can make sense when the rest are sound or when you are testing a frame colour and style before a larger renovation.
A full-home replacement can be more efficient because the site measure, manufacturing schedule, delivery, and installation are planned together. It also gives the exterior a consistent colour, frame line, and glass specification.
If the budget needs to be phased, group windows by elevation or room rather than choosing them at random. That keeps each completed section visually consistent and reduces repeated setup work.
What to send for an accurate early estimate
Send the following on WhatsApp:
- One clear photo of each window from inside or outside.
- The rough width and height of each opening.
- The number of windows you want to replace.
- Your preferred colour, if you already have one.
- Any concerns about privacy, noise, heat, security, or estate rules.
- Your Krugersdorp suburb and the best time for a site measure.
Rough dimensions are enough for an early conversation, but they should never be used as final manufacturing sizes. The installer must measure the actual opening before the frame is made.
Why local measurement matters in Krugersdorp
Older homes around Monument, Krugersdorp North, Kenmare, and the CBD often have steel frames set into openings that are no longer perfectly square. Newer homes and estates around Noordheuwel, Rant en Dal, and Featherbrooke may have colour, sightline, or glazing rules that must be matched.
A site measure catches those details before manufacturing, which is far cheaper than trying to correct the wrong frame on installation day.
