Where we work
We build supply before sales: a region opens for measures when a retrofit glazier there is under contract, and not before. Each page says which it is.
Double glazing Auckland
WaitlistAuckland 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.

WaitlistWellington's per-window retrofit prices are the best published in New Zealand, so a Wellington estimate on this site is the closest to a real quote before anyone visits. Wind zone is the local variable that can move it.

WaitlistChristchurch has a deep field of retrofit glaziers and a typical whole-house job at the national figure rather than above it. We have not yet published Christchurch-specific per-window rates, because we have not verified a Christchurch source at the level of Wellington Glass; the national bands apply until we have.

Questions about coverage
Which regions can you work in?
Auckland, Wellington and Christchurch are our first three, because they have the best published local cost data and the deepest field of retrofit glaziers. Each region page says whether measures are open there yet, or whether it is a waitlist.
What does 'waitlist' mean on a region page?
That we have not yet signed a subcontract with a retrofit glazier there. We do not sell a measure we cannot deliver, so until a glazier is under contract the buttons join a list and take no money.
Can I use the calculator if I'm somewhere else?
Yes. The rates behind it are national, so the estimate works anywhere in New Zealand. Only the measure and the quote depend on us having a glazier near you.
When will you cover Waikato, Bay of Plenty or Otago?
When we have both a contracted glazier and published local cost figures we can stand behind. We would rather leave a region off than put up a thin page about a place we cannot serve.
Do prices differ much by region?
Whole-job typicals do: CheckMyBuilder puts Auckland at $18,000, Wellington at $17,000 and Christchurch at $16,000. The per-m² and per-window bands are national.
