Aluminium windows Roodepoort: replacing steel windows
Large parts of Roodepoort, including Florida, Discovery, Horison, Roodepoort North, Wilro Park and Helderkruin, were built from the 1950s to the 1980s. Most of those houses had steel windows. After 40 or more Highveld summers, many of those frames have rusted at the bottom, no longer close properly, or have been painted so often that they stick. Replacing them is the most common aluminium windows Roodepoort job our local customers order for.
Step 1: measure the opening
Ask your installer to measure the opening brick-to-brick, or measure it yourself once the old frame is out. Our windows are made 10 mm smaller than the catalogue size, so a 1 200 × 1 200 mm window fits a 1 200 × 1 200 mm opening with room for packers and sealant. See how to measure aluminium windows.
Step 2: match the opening type
Steel windows in older Roodepoort houses are usually side hung casements with a fixed pane beside them, or top hung vents above. Replace like with like and the room will look and ventilate as it always has. To modernise, a top hung window or a sliding window is the usual upgrade.
Step 3: keep the burglar bars in mind
Many Roodepoort homes have burglar bars fixed inside the window reveal. Check that an opening sash will clear the bars before you choose the type. A top hung window opens outwards, so it usually clears bars mounted on the inside.
The full process is in replace steel windows with aluminium.

Aluminium windows Roodepoort: new homes and estates
The newer parts of Roodepoort, such as Ruimsig, Wilgeheuwel, Little Falls, Strubensvallei, Radiokop and Willowbrook, are mostly estates and cluster homes. These homes have bigger openings and a fixed palette of colours. To get aluminium windows Roodepoort estates will approve:
- Check the architectural guidelines. Most estates specify a frame colour, often Charcoal, Bronze or Black.
- Get approval before you order. Exterior changes usually need the HOA’s or trustees’ approval.
- Plan the access. Give the estate security the driver’s details in advance, or collect the windows yourself.
Aluminium windows Roodepoort: ridge views and exposed walls
Roodepoort sits along the Witwatersrand ridges. Homes on the slopes around Constantia Kloof, Roodekrans and Weltevredenpark often face open views and take summer storms head-on. If your windows face the weather:
- Choose top hung windows for openings that you want to leave open during the day. The sash is angled down and keeps most rain out.
- Keep the drainage slots at the bottom of every frame clear. Most leaks after a storm come from a blocked slot (see aluminium windows leaking).
- Make sure the installer runs a continuous bead of exterior sealant between the frame and the wall.
