When a glazier visits your home for the first time, you can generally expect them to assess the damage or job at hand, take precise measurements, discuss your options, and provide a quote. It's a straightforward process, but knowing what to prepare can help things go smoothly and get your glass sorted faster.
What the Glazier Will Do on Arrival
Most glaziers will start by having a good look at the window, door, splashback, or glass panel in question. They're checking the extent of any damage, the type of glass currently installed, and the condition of the surrounding frame. Don't be surprised if they ask a few questions about how the damage occurred — this can affect what replacement glass is recommended.
For a straightforward broken window pane, the visit might only take 15–30 minutes. For more complex jobs — like double glazing upgrades, frameless shower screens, or large architectural glass — expect a longer conversation.
Measuring Up
Accurate measurement is critical in glazing. Your glazier will measure the opening or frame dimensions carefully, often taking multiple measurements to account for any variation (older NZ homes in particular can have frames that are out of square). They may also check:
- The rebate depth (the groove the glass sits in)
- The thickness of the existing glass
- Whether the frame is timber, aluminium, or uPVC
- The sight lines and any beading or gaskets that need replacing
Bring up anything you've noticed, like draughts, condensation between panes, or difficulty opening and closing the window — these details help the glazier give you the right solution.
Discussing Glass Options
This is your chance to ask questions. A good glazier will walk you through the options suited to your situation. Common choices in NZ include:
| Glass Type | Common Use | Key Benefit |
|---|---|---|
| Standard float glass | Interior partitions, low-risk areas | Cost-effective |
| Toughened (tempered) safety glass | Doors, bathrooms, low-level glazing | Meets NZ safety requirements |
| Laminated glass | Overhead glazing, security | Holds together when broken |
| Double glazing (IGU) | Windows, doors | Thermal and acoustic performance |
| Low-E glass | Energy-efficient homes | Reduces heat loss |
Under the New Zealand Building Code (specifically clause F4 – Safety of Users), safety glass is required in certain locations — such as near doors, in bathrooms, and in low-level glazing. Your glazier should flag this automatically, but it's worth asking if you're unsure. You can check the requirements at MBIE Building Performance.
Will They Need a Building Consent?
Most like-for-like glass replacements don't require a building consent — they typically fall under Schedule 1 exemptions of the Building Act. However, if you're changing the size of an opening, upgrading to double glazing in a new configuration, or doing significant structural alterations, a consent may be needed. Always confirm with your local council before work begins if you're unsure. Your glazier should be able to advise you based on their experience, but the final call rests with your council.
Getting Your Quote
After measuring and discussing options, the glazier will usually provide a quote — either on the spot or within a day or two, depending on the complexity. A written quote should include:
- The type and thickness of glass specified
- Labour and any call-out fees
- Whether GST is included
- An estimated timeframe for completion
For standard single-pane replacements, some glaziers carry stock and can complete the job on the same visit. For custom-cut, toughened, or double-glazed units, glass typically needs to be ordered and a second visit scheduled.
What to Have Ready Before They Arrive
To make the most of the visit:
- Clear the area around the window or glass panel so the glazier can work safely
- If it's a broken window, leave the broken glass in place if it's safe to do so — it helps with measurement
- Know your frame material if possible (check old paperwork or look at the profile)
- Have a rough idea of your budget and priorities (e.g., energy efficiency vs. cost)
- Note any insurance claim details if the damage is covered — your glazier may be able to assist with documentation
When to Call a Professional
Glazing work — especially involving toughened or laminated safety glass, large panes, or structural glazing — should always be carried out by a qualified glazier. Incorrectly installed glass can be a serious safety hazard, and using the wrong glass type in regulated locations may not comply with the NZ Building Code. For guidance on safe work practices, WorkSafe NZ has useful resources. If your glazing job involves any electrical elements (like heated glass or integrated blinds), a licensed electrician registered with the Electrical Workers Registration Board must carry out that work.
