Four quick questions. Most quotes come back the same day.
Two things drive most of the volume here. The student quarter, where flats turn over fast and a broken pane needs sorting before the next tenancy starts. And the weather, which in Dunedin means a cold southerly arriving with rain behind it rather than the constant gusts you get further north. Break ins and stray cricket balls make up the rest.
What glass replacement costs
A standard sized single pane runs about $250 to $600 including callout, labour and glass. Larger panes sit between $600 and $1,200. A failed sealed double glazed unit is generally $350 to $800, and oversized panels can reach $1,200.
After hours work carries a callout on top. Toughened and laminated cost more than plain annealed glass, and obscure patterns can add lead time when the pattern has to come from a supplier rather than off the racks.
Safety glass is not a choice in some positions
NZS 4223 sets out where safety glass has to go: in and beside doors, in bathrooms and wet areas, in low level glazing somebody can walk into, and in large panes. If the pane we are replacing sits in one of those spots it goes back toughened or laminated whether or not the original was.
Older Dunedin homes very often have plain annealed glass in positions that would fail the standard today, simply because the rules changed after the house was built. Replacing a broken pane is the one cheap chance you get to fix that.
Matching old and obscure glass
Bathroom and hallway patterns run through a long list, and plenty of the 1960s and 70s ones are no longer made. We carry the current patterns and can usually get close on the rest.
Character homes are a different job. Original villa glass has ripples and slight distortion that modern float glass does not, and coloured leadlight panels need a leadlight specialist rather than a straight pane swap. We will tell you when a like for like match is not possible and show you the nearest option before we order.
Insurance claims
Most house policies cover accidental glass breakage, often with the excess as your only cost. We give you an itemised written quote and invoice listing the glass type, thickness and the standard it meets, which is what insurers ask for.
We do not tell you whether to claim. On a small pane the excess can be more than the job, so get the number first and decide with it in front of you.
How Window and Glass Repair Dunedin handles glass replacement in Dunedin
Most glass jobs are two visits. What happens on the first one decides how quickly the second one can happen and whether the result is compliant.
Identify the position against NZS 4223
Before anything is measured, Window and Glass Repair Dunedin establishes whether the opening is a safety glazing position. Doors, panels beside doors, low level glazing and anything next to a bath or shower all are. A lot of Dunedin housing predates the standard and has ordinary annealed glass in positions that now require toughened or laminated.
Identify what is there now
Existing thickness, whether it is annealed, toughened or laminated, and whether it is a sealed unit. Toughened glass carries a permanent stamp in one corner. Where there is no stamp and the position requires safety glass, the reglaze is the moment to correct it rather than repeat it.
Measure the rebate, never the broken pane
Glass sits inside the frame, so the measurement comes off the rebate with an allowance for edge cover and expansion. A pane cut to the size of the piece that broke will not fit, and in old timber joinery the rebate is rarely square.
Secure the opening if it cannot wait
If the building is insecure or the opening is exposed, Window and Glass Repair Dunedin boards it on the same visit. In a Dunedin winter an open window is not a next week problem, so the board goes on and stays weathertight until the glass arrives.
Order to specification
Standard clear glass in common sizes usually comes back within a day or two. Toughened, laminated, obscure patterns and sealed units are made to order. Window and Glass Repair Dunedin gives you the real date rather than an optimistic one.
Prepare the rebate before glazing
Old putty or tape out, rebate cleaned back, drainage checked and any decay in a timber rebate dealt with. New glass bedded onto old residue or soft timber is a repair with a short life.
Glaze, bead and clean down
Fresh glazing tape or putty, beads refitted properly rather than forced, and every fragment vacuumed from the track, the sill and the floor. Broken glass left in a slider track is what people find later with bare feet.
What makes glass replacement different in Dunedin
Three things about this city change how glass work gets specified.
A lot of the glass here predates the safety standard
In housing this old, original glass sits in positions the current standard would never allow. That is not an urgent hazard in itself, and it does become your decision the moment a pane breaks and gets replaced.
Original glass is worth keeping where it can be
Hand drawn and early float glass has visible ripple and distortion that modern glass does not. On a Victorian or Edwardian house that texture is part of the character, so Window and Glass Repair Dunedin replaces only the broken piece rather than the whole sash where the position allows it.
Cold glass and condensation get confused with leaks
With roughly fifty ground frost days a year, single glazing runs with water most winter mornings. People report it as a leak and reglazing does not change it. Window and Glass Repair Dunedin says so rather than quoting work that will not fix the complaint.
Salt air changes the hardware, not the glass
From St Clair round to Brighton and up the harbour to Port Chalmers, ordinary stays and catches pit within a few years. The glass is unaffected, the things holding it are not, and Window and Glass Repair Dunedin checks them while the sash is apart.
What glass replacement costs in Dunedin and how fast it happens
Glass pricing is driven by the type and the size, and the lead time is driven entirely by whether it has to be made to order.
Standard clear glass
A single pane in a common size typically runs $250 to $600 supplied and fitted. Larger panes, anything above about 1.2 metres in either direction, run $600 to $1,200 because both the glass and the handling change.
Safety glass and sealed units
Toughened and laminated cost more than annealed of the same size and are always made to order. A failed double glazed unit replaced in the existing frame runs roughly $350 to $800 depending on size and specification, and the frame, hardware and finish stay untouched.
Lead times you can plan around
Standard clear in a common size is usually back within twenty four to forty eight hours. Toughened, laminated, obscure patterns and sealed units are made to order, so allow several days and longer for unusual sizes. Window and Glass Repair Dunedin gives the real date at the measure.
What pushes a price up
Height and access, because anything above ground floor needs a ladder or a platform. Heritage putty glazing, because it is slower than beads. And obscure patterns that have to be sourced rather than held in stock.
Choosing the right glass for a Dunedin opening
Four decisions, and only one of them is really about budget.
Annealed, and where it is still allowed
Ordinary float glass, the cheapest option, and legitimate in positions the safety standard does not cover. In a door, beside a door, low to the floor or next to a bath it is not an option regardless of price.
Toughened
Several times stronger and it breaks into small blunt pieces. It cannot be cut or drilled after treatment, so it is made to size. The usual choice for doors, shower screens and low level glazing where a fall through is unlikely.
Laminated
Two panes bonded to an interlayer, so it stays in the frame when broken. Specified overhead, for balustrades, for security on accessible openings, and where UV fading matters. It costs more than toughened and it can be cut, which helps on awkward openings.
Sealed units, and the upgrades worth taking
If a unit is being made anyway, a low emissivity coating, an argon fill and a warm edge spacer add very little to the price. In climate zone 5 they are close to free performance and retrofitting them later means buying the unit twice.
Identifying the right glass for a Dunedin opening
Glass is not one product. Getting the specification right is a code question in some positions and a comfort question in others.
Safety glass positions are set by standard
NZS 4223 sets where toughened or laminated glass is required, including doors, glazing near floor level, bathrooms and areas adjacent to doors. Those positions are not optional and we will not reglaze them in annealed glass.
Toughened against laminated
Toughened is stronger and breaks into small blunt pieces. Laminated holds together in the interlayer when broken, which is why it is used for security, overhead glazing and noise control. They are not interchangeable.
Thickness follows the size and the exposure
A large pane on an exposed elevation needs more thickness than the same pane in a sheltered position. Wind load on the site is part of the calculation rather than a formality.
What happens on a Dunedin glass replacement
From the call to clean glass, most jobs are a two visit process and the first visit matters more.
Measure and secure
We measure the rebate rather than the broken pane, because glass sits inside the frame. If the opening cannot be left to the weather we board it the same day and glaze once the glass is cut.
Lead times differ by product
Standard clear glass in common sizes is usually back in within a day or two. Toughened, laminated and sealed units are made to order, so allow several days and longer for unusual sizes or obscure patterns.
Beads, seals and cleaning up
New glazing tape or putty, the beads refitted properly rather than forced, and every fragment vacuumed from the track and the floor. Broken glass left in a slider track is the thing people find weeks later.

Glass Replacement in Dunedin: common questions
How fast can you replace a broken window?
Common sizes in standard glass are usually measured and glazed within 24 to 48 hours. Toughened, laminated and sealed units are made to order, so allow several days to a week. We board up in the meantime.
Do I have to replace the whole window if one pane is broken?
No. In almost every case we replace the glass and leave the frame alone.
Can you replace glass inside a double glazed unit?
The unit is sealed, so the whole insulated glass unit gets replaced rather than one pane of it. Your frame and sash stay put.
Do you do student flats?
Constantly. We work with a number of property managers in the student quarter and can turn a broken pane around before a new tenancy starts.
Recent Dunedin jobs
Got three quotes for retrofitting the front of the house. Only ones who measured every opening and explained why the south facing rooms needed different glass. Fourteen windows over three days and the difference in the mornings is obvious.
Landlord here. Had four flats assessed before the inspections. Two just needed sashes freed up and stays replaced rather than new joinery, which saved me a fortune. Straight answers and a written report I could hand over.
Slider had been jamming for years and we assumed it needed replacing. Turned out to be rollers and a bent track. Two hours, a fraction of the price we were braced for.
Fogged unit in the lounge, measured on the Tuesday and in by the following Monday. Fair price and they cleaned up after themselves.
