Double glazing in Auckland
Auckland has more 1970s–90s aluminium-joinery houses than anywhere else in the country, and a large stock of pre-1940 timber villas and bungalows. Both can usually be retrofitted; which one you have changes the per-window price.
A typical whole-house double glazing job in Auckland costs about $18,000 (CheckMyBuilder, checked 15 Sept 2026). Per window, published New Zealand rates run $550–850 for an aluminium retrofit, $800–1,200 for timber, and $1,500–2,500+ per opening for full replacement.

- Superior Renovations, an Auckland renovation builder, publishes per-opening 'from' prices that lean towards full replacement rather than retrofit, which is part of why Auckland figures read higher than the national retrofit bands. (Superior Renovations)

Why Auckland is a waitlist today
We build supply before sales. Until a retrofit glazier in Auckland has signed a subcontract with us, given us their public liability certificate and put their sealed-unit warranty terms in writing, we will not take your money for a measure we cannot deliver. Join the waitlist and we will email you the day it opens. The calculator works fully in the meantime, because it only shows published market rates.
What the measure checks
- Whether your frames will take a thicker sealed unit at all.
- Frame condition: rot, corrosion, movement, failed seals.
- Hardware that has to carry the extra weight.
- Anything that takes the job outside the consent exemption.
- Exact glass sizes, which is what makes the quote fixed.
What we won't say about your region
We publish no climate-zone claims, no suburb lists and no local installer rankings for Auckland. Where we have a published local figure, it is above with its source. Where we do not, we have left it out rather than filled the space.

Can you do a measure in Auckland now?
Not yet. We have not signed a subcontract with a retrofit glazier in Auckland, and we will not sell a measure we cannot deliver. Join the waitlist and we will email you the day it opens; nothing is charged.
Is retrofit or replacement better for my house?
Retrofit if the joinery is sound and budget matters: $450–800 per m² of glass against $800–1,600 for replacement (CheckMyBuilder). Replacement if the frames have failed or you want thermally broken joinery. The full comparison.
Do I need a building consent?
Usually not in an existing dwelling of up to two storeys, under Schedule 1 Exemption 8, provided the window being replaced hasn't failed its 15-year durability requirement. Your council is the final word. The conditions.
Which suburbs of Auckland do you cover?
The whole of Auckland, once measures are open here. We do not publish suburb lists, because a page of suburb names tells you nothing about whether we can actually get to you.
