Window, door & balcony installation

Window, door & balcony installation in South Africa

Updated 4 November 2026

In South Africa a window, door or balcony installation usually costs from about R 2,500 per window supplied and fitted, and balcony aluminium doors in standard sizes are quoted at roughly R 4,500 to R 11,000. Larger jobs or specialist frames can reach R 15,000 per unit or more. The quickest way to current prices is a request on BlaBlaPrice, where the AI looks through local sellers' websites and price lists and shows what it finds.

Local rules to check before ordering

South African building regulations, known as SANS 10400, cover converting a door into a window or a window into a door, so ask the fitter whether your change needs approval. External walls are often load-bearing, so a wider opening may need a structural check before the frame is ordered. Fire-safety rules also limit how close a window can sit to a boundary line, which matters on small plots.

Season and timing

Summer runs from December to February and winter from June to August, and November sits between them. Work booked now can be finished before the December holidays, which many households aim for. Ask the fitter for a firm start date and the number of days the opening stays open, so a summer storm does not catch an unfinished wall.

How installation is bought here

Prices are quoted per window, per door or per unit, and labour-only quotes are separate from supplied-and-fitted quotes. Ask whether the price includes the frame, the glass, removal of the old window, sealing and finishing around the opening. Give sizes in millimetres, width by height, and say which suburb of Johannesburg, Pretoria, Cape Town, Durban or Gqeberha the site is in, because travel can change the quote.

What to write in the request

Say how many windows, doors or balcony doors you need and the size of each. Name the product specification you want, such as frame colour and glass type, and whether you already have the glass. Add who supplies the products, whether extra work such as wall repair or painting is needed, the site address, the deadline and your budget. These details let every fitter quote on the same basis.

Describe the job in your own words in the chat on BlaBlaPrice and add a photo of the opening if you have one. The AI asks for anything missing, such as the site address, then shows prices and businesses it found. Sellers registered on BlaBlaPrice receive the request and reply in the chat with their price, terms and delivery. Your contacts stay hidden until you decide with whom to exchange them.
