If you need aluminium windows Randburg-side, Coetz™ makes them to order at Laser Park, a short drive north-west of Randburg. You can price every window online, collect free from the workshop or have the windows delivered. Every window is made in 1–2 days, glazed with 6.38 mm clear laminated safety glass and finished in one of five colours. Randburg is a mix of sectional-title complexes, older freestanding homes and newer estates, and each needs a slightly different approach. This page covers all three, plus prices and delivery.
Coetz™ supplies only. Your builder, your complex’s contractor or a window installer fits the windows (see aluminium window installers).

Aluminium windows for Randburg complexes and townhouses
Ferndale, Windsor, Robindale, Bordeaux, Blairgowrie and Bromhof have a high share of sectional-title complexes and townhouses. Replacing aluminium windows Randburg complexes use is mostly about getting the paperwork right before you order:
Get the trustees’ approval
Under a sectional-title scheme, the outside of the building is common property. Exterior changes, including new windows, usually need the trustees’ approval and must follow the conduct rules. Ask for the approval in writing before you pay for anything.
Match the existing windows
Most complexes want every unit to look the same from outside. Before you order, check three things on the existing windows:
- Colour. White, Bronze or Charcoal cover most Randburg complexes, and all three cost the same.
- Opening type. Match top hung with top hung and sliding with sliding.
- Pane layout. Count the panes and note where the opening sash is.
Order the whole block together
When a body corporate replaces windows across a block, one combined order is easier to deliver and keeps every unit identical. The delivery charge is per order, not per window.

Aluminium windows Randburg: older freestanding homes
Linden, Northcliff, Blairgowrie, Fontainebleau and Kensington B have many freestanding homes from the 1950s to the 1970s. Many still have steel windows. To replace them with aluminium windows Randburg installers can fit:
- Measure the opening brick-to-brick once the old frame is out, and order the next standard size that fits. Our units are made 10 mm smaller than the catalogue size (see how to measure aluminium windows).
- Replace side hung casements with side hung windows to keep the look, or choose top hung windows to modernise.
- Check that the opening sash clears any burglar bars.
The full process is in replace steel windows with aluminium.
Aluminium windows Randburg: Northcliff Hill and exposed homes
Homes on Northcliff Hill and the higher parts of Linden and Blairgowrie look out over the city and catch summer storms and wind. Top hung windows are the safest choice for windows you leave open, because the sash is angled down. Keep the drainage slots at the bottom of the frame clear before the storm season (see aluminium windows leaking).
Aluminium windows Randburg: newer estates in North Riding and Olivedale
North Riding, Olivedale, Jukskei Park, Sundowner and Randpark Ridge have newer estates and cluster developments, often with larger windows and darker frames. Check the estate’s architectural guidelines for the colour (often Charcoal or Black). Then get HOA approval before you order and arrange gate access for the delivery.
