What affects the price
- Job size and scope — bigger or more complex jobs move you up the ranges above.
- Access and condition — hard-to-reach areas, older properties or neglected maintenance add labour time.
- Materials and quality level — where materials are involved, the grade you choose often matters more than labour.
- Urgency — same-day or out-of-hours work usually carries a premium.
- Where you live — large metros in South Africa typically run above the national range; smaller towns below it.

Frequently asked questions
Can draughty windows be fixed?
Yes — new compression seals/weatherstripping, hinge adjustment and lock realignment fix most draughts, and sash specialists rout in brush seals on older windows. It is one of the highest-payback repairs: cheaper heating bills and less noise without replacing anything.
Why is my window stiff, dropping, or not closing properly?
Usually worn friction hinges, tired rollers on sliders, or a dropped sash catching the frame. These are standard parts a repairer replaces in under an hour. Ignoring a dropping casement eventually strains the frame and glass, turning a cheap fix into a big one.
Can misted (fogged) double glazing be fixed without replacing the window?
Yes — the sealed glass unit swaps out of the existing frame, restoring clarity and insulation for far less than a new window. 'Demisting' services that drill the unit are cheaper still but results are mixed and insulation isn't restored; most pros recommend a new sealed unit.
Is it worth repairing a window or should I replace it?
Repair wins when the frame is sound: misted glass units, broken hardware, draughts and stiff sashes are all fixable at a fraction of replacement cost. Replace when frames are rotten through, warped, or repairs recur — or when energy performance is the real goal and the windows are single-glazed anyway.
How much does window repair cost?
Most window repairs are call-out jobs: hardware fixes (handles, hinges, locks, rollers) sit at the low end, replacing a failed double-glazed sealed unit sits mid-range, and structural frame or sash overhauls cost the most. Repair typically runs a quarter to half of replacement — get both numbers quoted when a window is marginal.
What does a sash window overhaul include?
A full overhaul strips the sashes out, replaces cords/springs and beads, eases and adjusts, adds draught brush seals, and re-hangs. It transforms operation and draughts while keeping original glass and joinery — the standard treatment for period timber windows before anyone talks replacement.
Do window repairs come with a warranty?
Reputable repairers warranty parts and labour — typically 1-2 years on hardware and 5-10 years on new sealed glass units. Ask specifically, because warranty length on the sealed unit is a good proxy for the quality of unit they fit.
Can old steel window frames be repaired in South Africa?
Yes — rust treatment, new putty glazing and hardware keep steel frames going for decades, typically R500-1,500 per window versus R3,000+ for aluminium replacement. Full replacement wins only when frames have rusted through.
