How to hire a window installation & replacement pro in South Africa
- Confirm compliance with SANS 10400-N glazing rules (safety glass in doors and low openings)
- Choose between aluminium (dominant), uPVC (growing) and timber; coastal homes need marine-grade finishes
- Ask for references and physical examples — no licensing exists for the trade
- Get per-window written pricing with disposal, sealing and plaster making-good included
- Check burglar-bar and security-screen integration upfront (standard SA requirement)
- Agree lead times and deposit terms with a written order
Frequently asked questions
Can windows be replaced in winter or bad weather?
Yes — pros replace one opening at a time so the house is never fully open, and cold-weather installation is routine in cold climates. Sealants and foams have temperature limits, so extreme cold or rain may shift a schedule, but winter is often the quieter, cheaper season to book.
What is double glazing and is triple glazing worth it?
Double glazing (two panes with a sealed gas gap) is the modern default. Triple adds insulation and noise benefits that matter most in cold climates and on noisy roads; elsewhere the extra cost rarely pays back. Spend first on installation quality and low-E coatings — a badly fitted triple-glazed unit performs worse than a well-fitted double.
Why is my double glazing misted up between the panes?
The sealed unit has failed and let moist air in. The fix is usually replacing just the glass unit, not the whole frame — a fraction of full replacement cost. Widespread misting across many windows of the same age suggests the batch is failing and full replacement may be better value.
Do new windows need planning permission or permits?
Like-for-like replacement is usually permit-free, but many places regulate windows through energy codes, safety-glass rules, and egress requirements for bedrooms — and heritage/conservation properties almost always need consent for changes. Your installer should know local rules; ask what paperwork you'll receive at completion.
What should a window installation quote include?
Per-window pricing with glazing spec, removal and disposal of old windows, making good internal reveals and external sealing, hardware, and warranty terms for both the unit (often 10 years) and the installation. Cheap quotes commonly exclude making-good — the messiest part.
How much does window replacement cost?
Windows are priced per opening: the unit itself (frame material, glazing spec, size) plus installation labour. A standard-size replacement in an existing opening is the base case; enlarging openings, upper-floor access, bay windows and heritage styles add meaningfully. Whole-house jobs get per-window discounts.
What do replacement windows cost in South Africa?
Standard aluminium windows typically land R2,500-6,000 per window fitted depending on size and spec, with uPVC similar to slightly higher. A typical house full replacement lands R25,000-60,000.
