04Buying guide
Questions to settle before converting
What happens to the burglar bars?
Many South African steel windows have bars built into the frame. They come out with the frame, so plan new burglar bars – we fit them at the same time.
Plaster and paint
We make good the plaster around every frame. Repainting the patched area is quoted separately or done by your painter.
Body corporate approval
In complexes, check the approved frame colour and style first. We can send a specification for the trustees.
Phase it if you need to
Converting room by room spreads the cost, and we keep the same profile and colour throughout.

10FAQs
Window Conversions FAQs
Straight answers to what Kempton Park and Johannesburg customers ask us most.
How much does a window conversion cost in Kempton Park?
From R4,200 per standard window all-in, R6,500 for a large window and R9,800 for a window-to-door conversion. New burglar bars add from R850 per window and double glazing from R950 per m².
Will my walls be damaged when the old windows come out?
Some plaster around the frame always comes away. We cut the old frame out carefully, fit the new window and make good the plaster so it is ready for paint.
My steel windows have built-in burglar bars. What happens to them?
They are part of the frame, so they are removed with it. We fit new burglar bars to the aluminium window at the same visit so the house is never left unprotected.
How long does it take to convert one window?
A standard window is usually removed, replaced and made good in under half a day. A whole house typically takes a few days.
Can I keep the same window size?
Yes. Most conversions use the existing opening. You can also enlarge it or turn a window into a door.
What colours are available?
White, charcoal, black, bronze, natural anodised and timber-look powder coat. In complexes we match the colour your body corporate has approved.
