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 New Zealand typically run above the national range; smaller towns below it.
How to save

- Be flexible on timing — off-peak slots are often cheaper.
- Bundle related tasks into one visit to spread call-out costs.
- Agree the scope in writing up front to avoid change-order surprises.

Frequently asked questions
How much does a frameless shower screen cost?
Frameless screens use 8-10 mm toughened glass with polished edges and specialist hardware, priced per panel plus installation. Semi-frameless and framed options run meaningfully cheaper. Accurate templating matters — out-of-square walls are why this is not a DIY product.
Where is safety glass legally required?
Almost every country requires safety glass (toughened or laminated) in doors, panels beside doors, low-level glazing, bathrooms and balustrades. Replacing broken glass in these spots with ordinary float glass is illegal and dangerous — a competent glazier will refuse to do it.
How much does mirror installation cost?
Custom-cut mirrors are priced per square metre plus polished edges, holes and fitting. Large wall mirrors need proper bonding or mechanical fixing to structure — a glazier job rather than adhesive strips. Bathroom mirrors should be moisture-backed to prevent edge blackening.
Does home insurance cover broken glass?
Commonly yes — glass breakage is standard in most contents/buildings policies, sometimes with an excess that makes small panes not worth claiming. For shopfronts, glass cover is usually a specific commercial policy item. Photograph the damage and keep the glazier's invoice either way.
What is the difference between toughened and laminated glass?
Toughened (tempered) glass is heat-treated to be several times stronger and crumbles into blunt granules when broken. Laminated glass sandwiches a plastic interlayer so it cracks but stays in place — better for security and overhead glazing. Codes dictate which is required where; laminated also blocks more noise and UV.
Can scratched or chipped glass be repaired instead of replaced?
Shallow scratches can sometimes be polished out of thick glass and small edge chips stabilized, but cracks always spread — a cracked pane needs replacement. For sealed double-glazed units, any crack means replacing the whole unit since the seal is compromised.
What does glass replacement cost in New Zealand?
A standard broken pane runs $150-400; toughened panels $250-600. Retrofit double-glazed units into existing joinery land $350-1,000 per window.
