Casement Windows South Africa

Casement Windows South Africa are the side hung windows that swing outwards on hinges, usually with a fixed pane beside them.

Prices JUST UPDATED. Ballpark figures, rounded, excluding VAT. They reflect typical South African aluminium window, door and glazing rates, supplied and installed. They are not our prices or quotations, and no provider is bound by them. Aluminium is MADE TO ORDER, so a firm price follows a site measure rather than a drawing, and the system, the glass and the finish move a quotation further than the size does. Confirm what each quotation includes, such as removing the old frame, making good, and the glass type for every opening.

What a Casement Window Quote Covers

The frame system. The profile range the window is built from. A light residential system and a heavy one look alike in a photograph.
The glass. Thickness, and whether safety glass is required at that height and position.
The finish. Mill finish, anodised or powder coated, each a different price and a different warranty.
Ironmongery. Handles, friction stays and restrictors, which are where a cheap window usually gives itself away.
Removal and making good. Taking the old frame out and repairing the plaster around the new one.

Where Quotes Differ Most

Whether the old frame comes out. A retrofit into an existing opening is a different job from a new build.
Opening sizes. Standard sizes come off a fabricator's regular cutting list. Odd sizes do not.
Glass specification. Safety glass, laminated glass and double glazing can each move the total sharply.
Finish and colour. Powder coating is ordered in, so one colour for the whole house is cheaper than three.
Access. First floor and above means scaffold or a platform, charged separately.

How the Work Runs on Site

The site measure comes first. A firm price follows the measure, not the drawing. Openings are rarely the size they were meant to be.
The frames are made to order. Nothing is pulled off a shelf, which is why lead time is part of the purchase.
The old window comes out. Usually the dustiest part of the job, and worth agreeing who cleans up.
The new frame is fitted and squared. Packed, fixed and checked for square before it is sealed, or the sash will never close evenly.
Sealing and glazing. Sealed to the brickwork outside and glazed, with beads on the inside.

What Affects the Price

The total area of glass. Square metres of opening is the figure every rate is built on.
The system. A heavier profile costs more a metre and is specified for bigger panes and wind load.
The glass. Safety, laminated and double glazed units each step the price.
The finish. Powder coating adds to natural anodised, and a non standard colour adds again.
Whether it is a retrofit. Taking out a steel frame and making good is real work with a real cost.
Where you are. Delivery and travel show up on a job outside a fabricator's usual radius.

What to Include in Your Request

The address. Suburb and town, so an installer knows whether they work there.
The opening sizes. Width and height of each one, even measured roughly with a tape.
What is there now. Steel, timber, older aluminium or a new opening with nothing in it.
The finish you want. Natural, bronze, charcoal or a specific colour.
Photos. One of each opening from the inside and one from the outside saves a visit.
Your timing. Frames are made to order, so lead time belongs in the conversation early.

Before You Appoint a Window Installer

Ask which system is quoted. Two quotes at different prices are often two different profile ranges.
Ask what glass is included. SANS 10400-N sets where safety glass is required, and it is not optional.
Ask who makes good. Plaster, paint and tiling around a new frame are the usual argument.
Ask about the finish warranty. Powder coating carries its own terms, and coastal exposure changes them.
Ask for the lead time in writing. Made to order means a date, and a date that slips costs you a trade.
Ask whether the quote is after a site measure. A price off a sketch is an estimate, not a quotation.

Casement Windows FAQs

How much do aluminium casement windows cost in South Africa?

Roughly R2,200 to R3,400 a square metre in natural anodised finish, supplied and installed, and R2,700 to R4,200 powder coated. A standard bedroom window usually lands between R4,500 and R8,000 fitted. Glass specification and the system move it more than anything else.

Are casement windows better than sliding windows?

They seal better, because the sash closes onto a gasket on all four sides rather than sliding past a brush. That makes them quieter and less draughty. A slider wins where the window opens onto a walkway or a narrow side passage and a swinging sash would be in the way.

Can aluminium windows be fitted into an existing opening?

Yes, and it is the usual job on an older house. The old steel or timber frame is cut out, the new aluminium frame is fitted and packed square, and the plaster is made good around it. Price the removal and the making good as separate items so you can see them.

Do I need safety glass?

It depends on the position and the height of the pane. SANS 10400-N is the part that deals with glazing and sets out where safety glass is required, for example in and beside doors and in low level glazing. Ask the installer to state the glass type for each opening on the quotation.

How long does it take?

The frames are made to order, so the lead time between accepting a quote and the install is usually several weeks. The fitting itself is quick: a small house of eight to twelve openings is commonly done in two to four days once the frames arrive.

Will the colour match my other windows?

Only if the same finish and colour code are specified. Natural anodised and a silver powder coating look similar in a brochure and different on a wall. If you are matching existing frames, say so in the request and send a photograph in daylight.

Casement windows are the opening most people price first, and Aluminium Windows South Africa carries the rest of the aluminium work on a house alongside them.
