Sliding Windows South Africa

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 Sliding Window Quote Covers

The frame system. Light residential track, or a heavier one for large panels and exposed walls.
The number of panels. Two panel, three panel or four panel, which sets how much of the opening opens.
The glass. Thickness by pane size, and safety glass where the position calls for it.
The finish. Mill finish, anodised or powder coated.
Rollers and the track. The part that decides whether the window still slides easily in five years.

Where Quotes Differ Most

Panel count. A three panel window in the same opening costs more than a two panel one.
Pane size. A large single pane needs thicker glass, and glass is priced by area and thickness.
Track quality. Stainless rollers and a drained track sit at the top of the range for a reason.
Coastal exposure. Within a few kilometres of the sea the sensible finish is a narrower choice.
Whether the old frame comes out. A retrofit carries removal and making good that a new build does not.

How the Work Runs on Site

The site measure. Every opening is measured, because a firm price follows the measure.
The frames are made to order. Cut, assembled and glazed to your sizes, which takes time.
The opening is prepared. The old frame out, the reveal cleaned up and checked for level.
The frame is fitted level. A sliding window that is out of level will drift open or jam, so this is the step that matters.
Sealing and adjustment. Sealed outside, then the rollers are adjusted so the sash closes onto the jamb evenly.

What Affects the Price

The total area. Square metres of opening, as with every window type.
How many panels. More panels means more profile, more rollers and more labour in the same opening.
The glass. Thickness rises with pane size, and safety or laminated glass steps it again.
The track and rollers. The cheapest option is the one that is replaced first.
The finish. Powder coating over natural, and a non standard colour over that.
Access. Anything above ground floor needs a platform or scaffold.

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.
How many panels you want. Or say how much of the opening you need to open, and let them advise.
What is there now. Steel, timber, older aluminium or a bare new opening.
The finish you want. Natural, bronze, charcoal or a specific colour.
Whether you are near the sea. It narrows the sensible finish and belongs in the brief.

Before You Appoint a Window Installer

Ask which system is quoted. The profile range explains most gaps between two prices.
Ask what the track and rollers are. This is the part that wears, and it is rarely itemised unless you ask.
Ask whether the track drains. A sliding track that holds water is a leak into the room below the sill.
Ask what glass is included. Thickness and type per opening, on the quotation.
Ask about the finish warranty. Especially within a few kilometres of the coast.
Ask who makes good. Plaster and paint around the frame, in writing.

Sliding Windows FAQs

How much do aluminium sliding windows cost in South Africa?

Roughly R2,100 to R3,300 a square metre in natural anodised finish, supplied and installed, and R2,600 to R4,100 powder coated. A two panel bedroom window commonly lands between R4,200 and R7,500 fitted, and a wide three panel window between R7,500 and R14,000.

Do sliding windows leak?

A well made one does not, but the track is where the risk sits. Water that blows into the track has to drain out again, so ask whether the system has drainage slots and whether the sill is set to fall outwards. A track with no way to drain will eventually show up as damp on the inside of the wall.

How many panels should I have?

In a two panel window only half the opening opens. A three panel gives you two thirds. More panels means more frame in your view and more cost, so the question is how much ventilation you need against how much glass you want to look through.

Are sliding windows less secure than casements?

Not by much, and it comes down to the lock rather than the type. Look for a multi point lock or a keyed catch rather than a simple lever, and ask whether the sash can be lifted out of the track when it is closed, which is the weakness on a cheap system.

Can I put a fly screen on a sliding window?

Yes. A sliding mesh panel runs on its own track alongside the sash, so it moves with the window rather than blocking it. It is cheaper to order with the window than to retrofit later, because the extra track has to be there.

How long does it take?

Frames are made to order, so expect several weeks of lead time before the install. The fitting itself is fast: a handful of openings is usually a day or two once the frames are on site.

Sliding windows and sliding doors are often bought together, and Aluminium Windows South Africa collects quotes for both in one request.
