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.

Paul's Glass & Glazing

When other glaziers said a larger pet door required a full glass replacement, Paul enlarged the existing hole instead, saving customers the cost of new glass entirely.

Drawn from 362 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 is quoted at about $600 to $800 per square metre by one Dunedin installer, and at $400 to $850 per window in aluminium frames or $800 to $1,200 per window in timber frames by a Christchurch installer. A whole-home retrofit runs roughly $12,000 to $25,000, while a 1990s house with ten aluminium windows lands closer to $5,000 to $8,500 installed.
Full window replacement, new frames included, costs $25,000 to $80,000 or more, making retrofit around 30 to 60 percent cheaper where the frames are still sound. For a single broken pane in an aluminium frame near ground level, one Auckland glazier quotes an average of about $320 plus GST, within a range of $200 to $800 plus GST, with timber frames and double-glazed units costing significantly more.
What moves either price is the frame type and condition, the glass specified (Low-E coating, argon fill, laminated, acoustic or safety glass), the window size and shape, the number of windows, travel distance, and access: glass above ground-floor height can require scaffolding, which adds substantially to the bill. These figures come from installer-published price guides, 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
Nothing in New Zealand 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 it was 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 windows. Under Schedule 1 of the Building Act 2004, window work on an existing house of up to two storeys is exempt from a building consent, unless the window being replaced previously failed the Building Code for durability (such as a window that leaked) or the work affects a specified system, though exempt work must still meet the Building Code.
Safety glass carrying a permanent NZS 4223.3 compliance mark is mandatory in showers, glass doors (including those fitted with pet flaps), balustrades, and similar risk areas. There is no glazier licence in New Zealand, but the Window and Glass Association New Zealand is the voluntary industry body and publishes 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 than full replacement when the frames are sound, which is why Nelson reviewers who had whole-house retrofits done in two days reported minimal disruption and tidy sites at the end of each working day. Full replacement is the better choice when frames 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 the frame itself no longer conducts cold from outside to inside. Whichever route you take, ask for Low-E glass, which carries a thin metallic coating that reflects heat back into the room, and bear in mind that double glazing keeps the inner glass surface warmer so condensation is less likely to form, but it does not remove moisture from the air, so you still need to open windows daily and run extractor fans when cooking or showering.
What are the warning signs of a glazier or double glazing company to avoid? expand_more
- –A quote that grows after the measure-up, with add-ons not mentioned on the phone or in the written estimate.
- –Demanding full payment before work begins, which left at least one Nelson customer feeling pressured and uncomfortable in their own home.
- –Long gaps between deposit and installation with little or no communication about where the job sits in the schedule.
- –Sealed double-glazed units that fog between the panes within a few years, combined with a company that is slow or dismissive when you raise a warranty claim.
- –Damaged paintwork, beading, or carpet caused during installation, with staff who blame the homeowner rather than acknowledging a workmanship issue.
- –A company that misrepresents its franchise affiliations or trading name, making it hard to know who you are actually dealing with if a dispute arises.
What should you ask before hiring a glazier or double glazing installer? expand_more
- –Are my existing frames sound enough to retrofit, or do they show rot, corrosion, or air leakage that would make full replacement the better option?
- –Exactly what glass is quoted, specifically whether it includes a Low-E coating, an argon fill, and safety glass (toughened or laminated with an NZS 4223.3 mark) in any door, shower, or balustrade panel?
- –How long is the wait from deposit to installation, and will you receive updates if the timeline shifts?
- –What does the warranty cover on the sealed units and on the workmanship, and for how many years does each part apply?
- –Does the quoted price include removing and disposing of the old glass, making good any paint and beading disturbed during installation, and scaffolding if upper-storey windows are involved?
- –For an urgent repair, what is the call-out fee, and will the opening be fully glazed on the day or temporarily boarded while a replacement pane is ordered?
