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 268 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 $600 to $800 per square metre of glass, or $400 to $850 per window in aluminium frames and $800 to $1,200 per window in timber frames. A whole-home retrofit sits between roughly $12,000 and $25,000, while full frame-and-glass replacement can reach $25,000 to $80,000 or more. For a single broken pane in an aluminium frame near ground level, expect around $320 plus GST on average, within a range of $200 to $800 plus GST. These are installer-published figures, and what moves the price is frame type and condition, glass specification such as Low-E coating or argon fill, safety glass requirements, window size and shape, the number of windows, and access: anything above ground-floor height can require scaffolding and will cost substantially more.
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 the coldest zones during 2023, and an alteration to an existing house only has to leave the window performance no worse than before. 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, not glazing. Under Schedule 1 of the Building Act 2004, window work in an existing house of up to two storeys is exempt from a building consent, except where the old window failed the code for durability or where the work affects a specified system, though exempt work must still meet the Building Code; safety glass carrying a permanent NZS 4223.3 mark is mandatory in showers, doors, balustrades and similar risk areas, and there is no glazier licence in New Zealand, though the Window and Glass Association New Zealand is the voluntary industry body and runs a member search.
Should you retrofit double glazing into your existing frames or replace the whole window? expand_more
Retrofit replaces only the glass in your existing frames, leaves the join between the window and the wall undisturbed, takes less time on site, and costs roughly 30 to 60 percent less than full replacement where the frames are sound, which matches what reviewers found: jobs were completed quickly, sites were left tidy, and final costs came in on or close to the quoted figure. Full replacement suits frames that are rotten, corroded, or draughty, and it is the only way to get thermally broken aluminium, uPVC, or new timber frames, which insulate meaningfully better than old plain aluminium because Low-E glass, a thin metallic coating that reflects heat back into the room, performs best when paired with a thermally efficient frame. Double glazing keeps the inner glass surface warmer so condensation is less likely to form, which reviewers noticed immediately, but it does not remove moisture from the air, so ventilation through opening windows and using extractor fans when cooking or showering still matters, especially if old plain aluminium frames remain.
What are the warning signs of a glazier or double glazing company to avoid? expand_more
- –A quote that rises after the measure, with extras only mentioned once the deposit is paid.
- –A long wait between paying the deposit and receiving an installation date, combined with little or no communication during that gap.
- –Sealed units that fog between the panes within a few years and a company that is slow or difficult to reach when you pursue the warranty.
- –Scratched or marked glass left in place, or damaged paintwork, beading and mess left behind after the job.
- –Emergency call-outs that arrive late or charge significantly more than the phone estimate given when you first called.
- –Sales pressure to sign a contract on the day of the quote, before you have had time to compare other options.
What should you ask before hiring a glazier or double glazing installer? expand_more
- –Ask whether your existing frames are sound enough to retrofit or whether rot, corrosion or draughts mean full replacement is the better option.
- –Ask exactly what glass is being quoted: whether it includes a Low-E coating, an argon fill, and safety glass rated to NZS 4223.3 in any door, shower or balustrade panel.
- –Ask how long the wait is from deposit to installation date, since some Dunedin installers run backlogs of several months.
- –Ask what the warranty covers on the sealed units and on the workmanship, and for how many years each applies.
- –Ask whether the price includes making good paint and beading and removing the old glass, so there are no surprise charges after the job.
- –For upper-floor windows, ask whether scaffolding is included in the quote, and for an urgent repair, ask about the call-out fee and whether the opening will be glazed or only boarded on the day.

Retrofit Double Glazing Dunedin (Metro Glass)
★ 4.9 13 reviews Top5 Score 1315★ 12 4★ 1Retrofit Double Glazing Dunedin takes on window retrofits that other glazing businesses have turned down, including cases where ageing aluminium frames were deemed too old to work with, finding solutions where competitors quoted full replacements instead. Gareth, Tania, and the installation crew coordinate the job from initial measure to final fit, and they travel well beyond Dunedin city to carry out on-site quotes.
