Buying Burglar Bars in Constantia — What’s Included
Every opening measured individually, bars fabricated to fit, powder-coated, and mounted into masonry. One quoted price. On Constantia properties we quote the main house and every outbuilding together, because the outbuildings are usually the weak point.
What We See Most Often on Constantia Windows
The tension in Constantia is between security and the view. These are houses bought for their outlook — over vineyards, oaks or up toward the Constantiaberg — and the windows are correspondingly large. Owners are understandably reluctant to put heavy vertical bars across a picture window, and quite often the result is that the window gets no protection at all, which is the worst of both outcomes.
There are better answers. Clear polycarbonate bars give an almost unbroken view while still resisting entry. Slimline steel in a colour matched to the window frame visually disappears at a few metres in a way that raw galvanised does not. On smaller side and bathroom windows, where the view matters less, conventional steel is more cost-effective and we will say so rather than upselling the clear option across the whole house.
The second Constantia issue is timber. A lot of the housing stock here has original or replica timber window frames, and bars fixed into timber are close to decorative — the frame will pull out long before the bar bends. We fix into the masonry reveal around the frame, which on thick old walls means a longer fixing and a more careful setting out, but it is the only mounting that actually holds.
Finally, damp. Mature oaks and heavy planting keep Constantia elevations shaded and slow to dry, and leaf litter traps moisture against steel. Coastal-grade powder coating is included as standard, and on shaded south-facing elevations it is doing genuine work.

Frequently Asked Questions
Can I secure a large picture window without ruining the view?
Yes. Clear polycarbonate bars are the usual answer on view elevations, and colour-matched slimline steel disappears visually at a few metres.
My windows are timber-framed — can you fit bars?
Yes, but we fix into the masonry reveal around the frame rather than into the timber itself. Bars fixed to timber will pull out long before they bend.
Can you quote for the cottage and outbuildings as well?
Yes, and it is worth doing. Outbuilding windows are consistently the least protected openings we find on Constantia properties.
Are the bars fire-safe for bedrooms?
Yes. Quick-release sets are fitted as standard on sleeping rooms.
How much do burglar bars cost to buy?
Cost depends on the number of openings, material and design — clear bars cost more than steel. Call 021 712 0484 for a free assessment.
Is a warranty included?
Yes, covering fabrication, coating, and fixings.
