Broken glass in a window or door creates more than a minor inconvenience. It can pose a serious safety risk, reduce your home’s security, and compromise comfort and weather-tightness.
If you are dealing with a cracked or shattered window in Wellington, knowing what to do next helps reduce risk, speed up repairs, and avoid unnecessary costs.
This guide covers:
- The different types of glass and how they break
- Immediate safety steps to take
- What affects repair time and cost
- Why glaziers ask detailed questions
- How to get your repair sorted efficiently
Types of Broken Glass (And Why It Matters)
Different glass types break in different ways. Identifying the glass type helps you stay safe and can make the repair process by your glazier more efficient.
Annealed Glass
Annealed glass breaks into sharp, jagged shards and poses the highest injury risk. This is the most common type of glass in most homes and standard mirrors.
Toughened Safety Glass
Toughened glass shatters into hundreds of small, blunt pieces. It is most commonly used in bathrooms, doors, and low-level glazing where safety matters most.
Laminated Safety Glass
Laminated safety glass contains a plastic interlayer sandwiched between two panes of glass that holds the glass together when it breaks. Cracks form, but the pane usually stays intact, reducing injury risk and improving security.
Tip: Treat broken annealed glass with extreme caution due to its sharp edges.
Safety First: What to Do Immediately
When a window or door breaks, take action as soon as it is safe.
Isolate the Area
Keep people, children and pets away from the broken glass. Close the room off if possible.
Clear Loose Glass Carefully
Use a broom or vacuum while wearing thick gloves. Avoid touching shards directly.
Check Surrounding Areas
Glass fragments can travel some distance if broken by an impact, and be found on or under furniture, behind curtains, or in piles of clothing, toys or books. It’s important to check surrounding areas carefully, both inside and outside.
Stabilise Cracks
If the glass has cracked but remains in place, apply wide tape along the crack to limit movement. Be careful not to apply too much pressure.
Make the Opening Weather-Tight
Cover the opening with thick plastic, cardboard or plywood to protect against wind and rain.
If handling broken glass feels unsafe, contact a professional glazier immediately.
Broken Window Repair: What Affects Time & Cost?
Several factors influence how quickly repairs can happen and how much they cost.
Single vs Double Glazing
Annealed and laminated single glazing can often be replaced the same day in a single visit, using stock glass cut on site. Double-glazed units require recognition of glass types, precise measuring and manufacturing, which typically takes 5–8 working days and requires two visits.
Safety Glass Requirements
Toughened safety glass also requires two visits: one to measure and assess, and one to install after manufacture. Laminated safety glass may sometimes be cut on site, depending on size and specification.
Glass Type and Finish
Privacy, textured, frosted, tinted, or coloured glass costs more than standard clear glass and often requires ordering. Where possible, Wellington Glass & Mirror holds selected options in stock to reduce wait times.
Size, Shape and Weight
Large panes, double-glazed units, or custom shapes increase labour requirements and handling complexity.
Access and Height
Most windows require both external and internal access for glazing. Windows higher than approximately two metres from ground or floor level may need scaffolding or specialised access equipment.
Why We Ask So Many Questions
When you contact a glazier about broken glass, detailed questions help determine whether we can attend immediately or need to assess the glass and access requirements first.
You may be asked:
- Is the glass in a window or a door?
- Is it opening or fixed?
- Is it single or double glazed?
- Is the glass secure or unstable?
- Is it in a bathroom or near stairs, a landing, or a doorway?
- Is it within 1 metre of the floor or ground level?
- Is it clear, obscure, tinted, or coloured?
- What material is the joinery (timber, aluminium, steel, or PVC)?
- What is the approximate size of the glass?
- Is access easy from inside and outside?
Photos Help
Clear photos save time and reduce costs. If possible, send images showing:
- The full window or door from inside and outside
- Height above floor and ground level
- The type of break and glass
- External joinery details, showing a close-up of at least one corner.
This allows the team to arrive prepared with the correct glass and materials.

Frequently Asked Questions: Broken Window Repair in Wellington
How urgent is broken window repair?
Broken windows should be addressed as soon as possible. Even small cracks can worsen quickly in Wellington’s wind and weather. Broken glass also poses safety risks, reduces security, and compromises weather-tightness. We offer fast, professional repairs, with most jobs completed within 1–3 days.
Can broken glass be replaced the same day?
Annealed and many types of laminated safety glass can be replaced the same day. Broken glass poses safety risks, reduces security, and compromises weather-tightness. Even small cracks can worsen quickly in Wellington’s wind and weather. We aim to complete most repairs within 1–3 days, depending on glass type and availability. Double-glazing units and toughened safety glass needs to be precisely measured and then manufactured before it can be replaced, which takes a few days longer. Timeframes are indicative only and not guaranteed.
How long does it take to replace double-glazed glass?
Double-glazed units generally take 5–8 working days to manufacture after accurate measurement. Installation usually happens on a second visit once the unit is ready.
Is safety glass required for all window replacements?
Not all windows require safety glass, but New Zealand Building Code regulations apply in certain situations. Safety glass is typically required in:
- Bathrooms
- Doors
- Low-level windows (within 1 metre of floor or ground level)
- Areas near stairs, landings, or fall hazards
Your glazier will assess this and ensure the replacement glass meets current compliance requirements.
What should I do if the glass is cracked but not shattered?
If the glass is cracked but still in place, you can temporarily stabilise it with wide tape applied gently along the crack. Avoid pressure, and keep people, children and pets away until a professional repair is completed.
Does broken glass always need a site visit first?
Not always. If you can provide clear photos, measurements, and details about the glass, joinery and access, a glazier may be able to attend with the correct materials straight away. More complex jobs, such as double glazing, toughened safety glass, or windows requiring scaffold, elevated work platforms or abseilers usually require a prior assessment.
What information helps speed up a glass repair?
To help your glazier respond efficiently, it is useful to know:
- Whether the glass is in a window or door
- If it is single or double glazed
- The approximate size of the glass
- The joinery type (timber, aluminium, steel, or PVC)
- Whether access is easy or at height
- Whether the glass is clear, frosted, tinted, or textured
Photos from inside and outside are especially helpful.
Do you repair both residential and commercial glass?
Yes. Wellington Glass & Mirror provides glass repair and replacement services for homes, apartments, shops, offices, schools, and community buildings throughout the wider Wellington region.
