Window Installers South Africa

Window Installers South Africa are the trade that takes the frame out of the van and leaves it square, sealed and working. It is a separate skill from fabricating, and on a retrofit it is most of the job: cutting out the old frame, packing the new one true and making good the plaster. Say whether you have the frames already or need supply and fit, and get priced quotations to compare.

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 an Installation Quote Covers

Removing what is there. Cutting out a steel or timber frame, and getting rid of it.
Preparing the opening. Checking the opening is square, plumb and the right size.
Fitting and fixing. Packing the frame true and fixing it to the structure.
Sealing. A weather seal outside, which is what keeps water out of the wall.
Making good. Plaster around the reveal, and sometimes paint and sills.

Supply and Fit, or Fit Only

Supply and fit is one responsibility. If the frame is wrong, it is the same company who made it.
Fit only splits the risk. A fitter who did not measure will not carry a frame that does not fit.
Fit only suits frames you already own. An inherited order, a change of mind, or frames bought direct.
Measure before you order. Most fit only problems start with a measurement nobody owned.
Say which you want. The two are quoted differently and are not comparable line for line.

Where Quotes Differ Most

Retrofit or new build. A bare opening in new brickwork is a fraction of the work of a steel removal.
How many openings. A day rate spread over ten windows is cheaper an opening than over two.
What has to be made good. Plaster, paint, tiling and sills are the items that quietly add up.
Access. Upper floors need a platform or scaffold, charged separately.
Whether the openings are square. An old house rarely has openings the size the drawing says.

What Affects the Price

Retrofit or new build. The single biggest difference in an installation price.
How many openings. Mobilisation is spread over the job, so a bigger job is cheaper an opening.
What is being removed. Steel, timber and older aluminium are three different removals.
How much making good. Face brick needs almost none; plastered and painted walls need the most.
Access. Scaffold or a platform on anything above ground floor.
Travel. A job outside the usual radius carries travel and sometimes accommodation.

What to Include in Your Request

The address. Suburb and town.
Whether you have the frames. Supply and fit, or fit only. Say which.
How many openings. And their sizes, even roughly.
What is there now. Steel, timber, older aluminium or a bare opening.
What needs making good. Plaster, paint, tiling or sills.
Photos. Inside and outside of each opening saves a site visit.

Before You Appoint an Installer

Ask who owns the measurement. On fit only work this is the question that prevents the argument.
Ask what making good is included. Plaster is usually in, paint usually is not.
Ask how the frame is sealed. The outside weather seal is what keeps water out of the wall.
Ask about rubble removal. Old steel frames and broken plaster have to leave the site.
Ask what happens if an opening is out of square. It is common in older houses and it belongs in the conversation early.
Ask for public liability cover. Fitting involves cutting into walls, and cover should name that work.

Window Installers FAQs

How much does it cost to fit an aluminium window in South Africa?

Into a bare opening, roughly R650 to R1,600 per window. Into an existing opening where an old frame has to come out, R1,100 to R3,200 per opening once removal and making good are added. A two person installer team typically works at R2,200 to R4,800 a day.

Should I buy supply and fit, or buy frames and hire a fitter?

Supply and fit puts one company behind the measurement, the frame and the installation, which matters when something does not fit. Fit only can be cheaper if you already have the frames or are buying direct, but you take on the risk that the sizes are wrong. If you go that route, have the fitter measure before the order is placed.

How long does it take to replace the windows in a house?

Once the frames are made, a house of eight to twelve openings is commonly done in two to four days. The long part is the lead time on the frames, which is usually several weeks, so book the trades that follow after the frames are confirmed rather than before.

Will they make good the plaster?

Most installers include basic plaster repair around the reveal, and most exclude painting. Tiling, sills and skirting repairs are usually extra. Ask for making good to be listed as its own line so you can see what is and is not in the price.

Can windows be replaced while we live in the house?

Yes, and it is the normal way it is done. The work is room by room, so one or two openings are open at a time. It is dusty, particularly when steel frames are cut out, so cover furniture and expect to clean up afterwards.

Do installers handle upper floor windows?

Yes, but the access has to be priced. That is usually a mobile platform or scaffold, charged by the day, and on a large pane it can be the biggest single item on the quotation. Say how high the openings are in the request.

Fitting is the half of the job that decides whether a window works, and Aluminium Windows South Africa puts installers and fabricators in front of you together.
