Before you hire
The same businesses fix a broken pane and double glaze a house, so one list covers both. For retrofit double glazing, ask whether your existing frames are sound enough to keep, what glass is quoted (Low-E and an argon fill cost more and insulate better), and whether doors, bathrooms and low windows are priced with safety glass, which carries a permanent NZS 4223.3 mark. Replacing windows in a house of up to two storeys does not usually need a building consent, unless the old ones leaked. There is no glazier licence in New Zealand; Window & Glass Association New Zealand membership is voluntary.

Drawn from 209 customer reviews collected for this page. The first answer is what it costs.
How much does double glazing or a glass repair cost in New Zealand? expand_more
Retrofit double glazing runs from about $400 to $850 per window in aluminium frames and $800 to $1,200 per window in timber frames, or roughly $600 to $800 per square metre of glass. A whole-home retrofit sits between about $12,000 and $25,000, while full window replacement with new frames costs $25,000 to $80,000 or more. Retrofit is roughly 30 to 60 percent cheaper than full replacement where frames are sound. For a broken single pane in an aluminium frame, expect around $320 plus GST, with a range of $200 to $800 plus GST depending on the job. Frame type and condition, Low-E coating, argon fill, safety glass, window size and shape, the number of windows, and access above ground level (which can require scaffolding) all move the price. These are installer-published figures and no independent New Zealand source publishes glazing prices.
Is double glazing required by law, and does replacing windows need a building consent? expand_more
No law requires an existing home to be double glazed. Building Code clause H1 sets minimum window insulation values only for new housing, starting at R0.37 nationwide from 3 November 2022 and rising to R0.46 or R0.50 in colder climate zones during 2023. An alteration to an existing house only needs to leave the window performance at least as good as before, so replacing a single-glazed window does not force an upgrade. The healthy homes standards for rental properties require ceiling and underfloor insulation, not double glazing, and the Warmer Kiwi Homes programme funds insulation and heat pumps but not windows or glazing. Under Schedule 1 of the Building Act 2004, replacing a window in an existing house of up to two storeys is exempt from a building consent, unless the original window leaked in breach of the durability code or the work affects a specified system, and exempt work must still meet the Building Code. Glass in doors, showers, balustrades and overhead glazing must be safety glass, identifiable by a permanent NZS 4223.3 compliance mark. There is no glazier licence in New Zealand; the Window & Glass Association New Zealand is the voluntary industry body and publishes a member search.
Should you retrofit double glazing into your existing frames or replace the whole window? expand_more
Retrofit makes sense when the frames are structurally sound: it replaces only the glass, leaves the join between window and wall undisturbed, is quicker to complete, and costs substantially less than full replacement. Full replacement is the better choice when frames are rotten, corroded, or draughty, and it is the only route to thermally broken aluminium, uPVC or new timber frames, which insulate better than old plain aluminium because standard aluminium conducts heat even with double-glazed units fitted. Low-E glass has a thin metallic coating that reflects heat back into the room and is worth specifying regardless of which route you take. On condensation, double glazing keeps the inner pane warmer so moisture is less likely to form there, but it does not remove humidity from the air, so ventilating rooms and running extractor fans when cooking or showering still matters. Reviewers across several retrofit installers noted crews arriving on time, cleaning the glass on completion, and tidying up fully, so it is fair to ask any company upfront whether that is standard practice.
What are the warning signs of a glazier or double glazing company to avoid? expand_more
- –Minimum call-out charges or per-tradesperson hourly minimums that are not disclosed before you book, leaving you with a bill far above what a short job would reasonably cost.
- –Missed appointment times with no advance call or message, or repeated rescheduling after a deposit has been paid.
- –Invoices that log more hours than were actually worked on site, especially where the customer was present the whole time.
- –A contact form or email address on the company website that does not work, combined with slow or absent follow-up to enquiries.
- –Dismissive responses to urgent jobs, such as citing a week-plus lead time for a security-critical broken pane without offering a temporary board-up.
- –Incomplete finishes left after installation, such as unfilled holes in exterior cladding or incorrect hardware colours, followed by slow and reluctant remediation.
What should you ask before hiring a glazier or double glazing installer? expand_more
- –Ask whether your existing frames are in sound enough condition for a retrofit or whether they need replacing before any glass work is quoted.
- –Confirm exactly what glass is specified in the quote, including whether it is Low-E, whether it has an argon fill, and whether safety glass is included where it is required by the Building Code.
- –Ask how long the wait is from paying a deposit to the installation date, and what communication to expect if parts are delayed or damaged in transit.
- –Find out what the warranty covers on the sealed units and on the workmanship, how long each warranty runs, and what the process is if a unit fogs between the panes.
- –Check whether the price includes removing and disposing of old glass, making good any paintwork or beading disturbed during installation, and scaffolding for upper-storey windows.
- –For an urgent repair, ask for the call-out fee and any per-tradesperson minimum charges upfront, and confirm whether the opening will be glazed the same day or boarded temporarily.
