About NZ Double Glazing
A retrofit double glazing company that publishes its numbers first, measures once, and gives you a fixed written quote under one contract.
NZ Double Glazing prices retrofit double glazing and window replacement window by window online, from published New Zealand rates with their sources shown. One paid measure turns that estimate into a fixed written quote under a single contract with us. A contracted retrofit glazier makes the sealed units and fits them.
Why we exist
Every double glazing company in New Zealand offers a free measure and quote, and none of them will tell you a price before a salesperson has been to your house. Meanwhile the cost guides publish real numbers but cannot do the job. We thought someone should do both: publish the numbers, and take the work at them.
What we actually do
- Publish the market rates we work from, with the source and the date we checked each one, and re-check them quarterly.
- Run a calculator that takes your own window measurements rather than a room count.
- Send a glazier to measure for $149, credited in full against a job you sign within 60 days.
- Write one fixed quote, hold one contract, and sign the work off at the end.
Who fits the glass
Not us. A retrofit glazier we contract in your area makes the sealed units and fits them into your frames, or replaces the window. We name them before they come to your house. That arrangement is on every page of this site rather than buried, because you should know who is standing in your lounge.
How we choose glaziers
- A signed subcontract with us, so the obligations run both ways.
- A current public liability certificate, and our own cover as well.
- Sealed-unit warranty terms in writing, from the manufacturer, not a verbal promise.
- Membership of the Window and Glass Association New Zealand where we can get it, because it comes with a dispute process.
- Trade prices per window type and per m², so we can check our published bands still hold.
Until all of that is in place in a region, that region's page says "waitlist" and the site takes no money for a measure there. Today that is all three of our launch regions.
What we will not claim
- Reviews, ratings or job counts. We have not done a job yet, and inventing either would be the fastest way to deserve none.
- Trade memberships, accreditations or warranties of our own until we hold them.
- Energy savings, payback periods or heat-loss percentages for your house. We quote EECA and BRANZ as they state things, and no further.
- Precise quotes without a measure. The estimator shows ranges, and says so on every screen.
Where we work
Auckland, Wellington, Christchurch are our first three regions, chosen for their published local cost data and their depth of retrofit glaziers. The calculator works anywhere in New Zealand, because its rates are national.
