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 153 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, or $400 to $850 per window in aluminium frames. Timber frames cost more, from $800 to $1,200 per window, and a whole-home retrofit sits between $12,000 and $25,000. Full window replacement, new frames included, jumps to $25,000 to $80,000 or more, making retrofit roughly 30 to 60 percent cheaper where frames are sound. For a broken single pane in an aluminium frame, expect around $320 plus GST, within a range of $200 to $800 plus GST, with timber frames and double-glazed units costing more. Frame type and condition, Low-E coating, argon fill, safety glass, window size and shape, the number of windows, travel distance, and access all move the price. Glass above ground-floor height can require scaffolding, which adds meaningful cost. These figures come from installer-published price guides, not an independent source.
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 zones during 2023. When you alter an existing house, the window only needs to perform at least as well as before, so a like-for-like replacement 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. Under Schedule 1 of the Building Act 2004, replacing a window in an existing house of up to two storeys is exempt from building consent, unless the old window failed the code for durability or the work affects a specified system, though exempt work must still meet the Building Code. Glass in doors, showers, balustrades and similar risk areas must be safety glass, identifiable by a permanent NZS 4223.3 compliance mark. There is no glazier licence or registration in New Zealand; the Window and Glass Association New Zealand is the voluntary industry body and runs a member search if you want to check whether an installer belongs.
Should you retrofit double glazing into your existing frames or replace the whole window? expand_more
Retrofit replaces only the glass inside your existing frames, leaves the join between the window and the wall untouched, and costs substantially less when the frames are sound. Full replacement suits frames that 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 the frame itself no longer conducts cold inward. Low-E glass has a thin metallic coating that reflects heat back into the room, and it can be fitted in either approach. Double glazing keeps the inner glass surface warmer, so condensation is less likely to form there, but it does not remove moisture from the air, meaning ventilation through opening windows and running extractor fans still matters, and a plain aluminium frame can still run with condensation even after a retrofit.
What are the warning signs of a glazier or double glazing company to avoid? expand_more
- –A quote that grows noticeably after the measure-up, with no clear explanation of what changed, is a red flag before work even starts.
- –Missed or very late appointments, especially for a quoted visit, suggests scheduling and communication problems that tend to carry through the whole job.
- –Poor communication between deposit and installation, with little update on lead times or delivery delays, leaves you exposed if something goes wrong with the order.
- –After-hours or emergency call-outs that arrive late or cost far more than the phone estimate point to unreliable pricing and dispatch.
- –A completed job where the wrong material was used, such as the wrong putty colour or finish, and the company is slow or reluctant to return and fix it, signals weak quality control.
- –Silence after a measure-up, where a quote is promised but never arrives despite follow-up, is worth treating as a firm reason to move on to another installer.
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 replacement is the better option, and get the reasoning in writing.
- –Confirm exactly what glass is being quoted: whether it includes a Low-E coating, argon fill, and safety glass in any location where NZS 4223.3 requires it.
- –Ask how long the wait is from deposit to installation, and what happens if the glass arrives damaged or is the wrong size.
- –Find out what the warranty covers on the sealed units and on the workmanship, how long each warranty runs, and who you contact if a unit fogs between the panes.
- –Check whether the price includes removing and disposing of the old glass, making good any paint or beading disturbed during installation, and leaving the site clean.
- –For upper-floor windows, ask whether scaffolding is included or quoted separately, and for an urgent repair, confirm the call-out fee and whether the opening will be boarded or fully glazed on the same visit.
