If you’ve spotted a small chip on your windscreen this week, you’re not imagining it; spring temperature changes around Ravenhall can put extra stress on an already damaged windscreen. As temperatures shift between cool mornings and warmer afternoons, a small chip can sometimes develop into a larger crack.
This guide covers why that happens, how to check if your chip is at risk, and when it’s time to book windshield repair in Ravenhall before the damage gets worse. We’ll also look at what Victorian roadworthiness requirements say about damaged windscreens, and when a crack means you need more than glass work.
WHY SPRING WEATHER IS HARD ON A CRACKED WINDSCREEN
Glass expands slightly when it warms up and contracts when it cools down. An undamaged windscreen handles this every day without any trouble.
A chip breaks that smooth surface, though. It creates a weak point where stress can build up.
When temperatures swing quickly, like a cold morning followed by a warm afternoon, the glass around that chip expands unevenly. That uneven stress is often enough to turn a small chip into a long crack, sometimes within hours.
This kind of swing isn’t rare in Melbourne’s west. In October 2025, Melbourne’s coolest day reached just 14.0°C, while the warmest day that same month hit 30.1°C, according to the Bureau of Meteorology’s monthly climate summary for Melbourne. A jump like that puts real strain on a windscreen that already has damage.
A few everyday habits make things worse:
- Blasting the demister or heater straight onto cold glass
- Parking in direct sun straight after a cold night
- Driving through a puddle that splashes cold water onto hot glass
- Slamming car doors, which sends a small shock through the whole windscreen
None of these habits cause the original chip. But any one of them can be the final push that turns a small mark into a crack running across your windscreen.
HOW TO TELL IF YOUR CHIP IS AT RISK
Not every chip is a ticking time bomb, but Victoria does have clear legal limits for windscreen damage.
Under VicRoads’ VSI 26 roadworthiness requirements, a laminated windscreen may be rejected if it has a bullseye or star fracture over 16mm in diameter, or a crack over 150mm long, within the area swept by the windscreen wipers. Any crack that penetrates more than one layer of glass is also a rejection point. Even smaller damage can be an issue if it impairs the driver’s vision enough to make the vehicle unsafe.
LIKELY LOWER RISK FOR NOW, BUT STILL WORTH FIXING SOON
- Smaller than 16mm across
- Sitting outside the area your wipers sweep
- Hasn’t reached the edge of the glass
HIGHER RISK — GET IT LOOKED AT STRAIGHT AWAY
- Sitting near the edge of the windscreen
- Has spidery cracks branching out from it (a “star break”)
- Has already grown or changed shape since you first noticed it
- Sits in the driver’s direct line of sight
If you’re not sure, take a photo and arrange an assessment rather than waiting for the chip to grow. Early attention may improve the chance that the damage can be repaired before it spreads.
We’ve covered the full breakdown of repair versus replace in our detailed guide on cracked windscreen repair or replace, which is worth a read if you want to understand your options in more depth.
WHY A CRACKED WINDSCREEN ISN'T JUST A COSMETIC PROBLEM
Your windscreen does more than block the wind. On many vehicles, it’s built into the structural design of the car. Government vehicle construction standards note that if it’s damaged or not properly secured, this can reduce the vehicle’s structural integrity.
There’s a roadworthiness issue too. In Victoria, windscreen damage may result in a vehicle defect notice depending on its severity and its effect on safe driving. The notice will specify when the vehicle must stop being driven and what is required to clear the defect.
A small chip may be repairable if it is assessed early, depending on its size, depth and location. If it’s left for a few weeks of spring weather, it can spread into a crack that’s no longer repairable — only replaceable.
WHAT TO DO WHEN YOU SEE A CHIP
Until you can have the chip professionally assessed, a few simple precautions may help prevent further damage.
- Take a photo. This helps if you need to make an insurance claim later.
- Cover it with clear tape. This keeps dirt and moisture out until you can get it looked at.
- Avoid extreme temperature changes. No boiling water on frosty glass, no full-blast heater aimed straight at cold glass.
- Book an assessment as soon as you reasonably can. The sooner a chip is checked, the better the chance it can be repaired rather than replaced.
- Check your own insurance policy. Cover for windscreen chip repairs varies between insurers, so it’s worth confirming what your policy includes before you book.

WHEN YOU NEED CAR SMASH REPAIR IN RAVENHALL, NOT JUST GLASS WORK
Sometimes a windscreen doesn’t crack from a stone chip. It cracks after a knock, a scrape, or a low-speed bump, maybe reversing out of a driveway near the Western Freeway or backing out of a tight car park in Caroline Springs.
If the windscreen was damaged during an impact, it may be worth having the whole vehicle assessed rather than looking at the glass alone. A car smash repair specialist in Ravenhall can check for related body or structural damage.
If the windscreen cracked during an impact, there may also be damage to nearby panels or structural areas around the windscreen and A-pillar. A broader inspection can help identify any related issues before repairs begin.
A thorough smash repair check should include:
- Panel and bodywork damage assessment
- Frame and chassis alignment check
- Structural inspection around the A-pillar
- Paint matching and surface finishing
- ADAS camera and sensor calibration checks where required
- A final safety and repair-quality inspection before the vehicle is returned
If your car isn’t safe to drive after a knock like this, don’t try to get it home yourself. A reliable towing service in Ravenhall can get your car to a workshop safely, without adding further damage or putting you at risk on the road, and the workshop can then run a proper car smash repair assessment in Ravenhall before any glass work begins.
WHAT PROPER WINDSHIELD REPAIR IN RAVENHALL ACTUALLY INVOLVES
Professional windscreen chip repair in Ravenhall generally follows a clear assessment and repair process.
01 — INSPECTION
The technician checks the size, depth, and location of the damage, and confirms whether repair or replacement is the right call.
02 — CLEANING
Dirt and moisture are removed from the chip. This step matters because trapped contamination can cause a repair to fail.
03 — RESIN INJECTION
A clear resin is injected into the chip to fill the gap and bond with the glass.
04 — CURING
UV light is then used to cure and harden the resin.
05 — FINAL CHECK
The finished repair is checked for clarity and surface finish before the vehicle is returned to you.
All glazing fitted to vehicles in Australia has to meet the Australian Design Rules, the national vehicle safety standards administered by the Department of Infrastructure, Transport, Regional Development, Communications, Sport and the Arts. A proper windshield repair in Ravenhall works within that framework, so your windscreen keeps doing its job as a safety feature, not just a clear pane of glass.

FAQS
QUESTIONS & ANSWERS
Common questions about windscreen chips, cracks, repair and smash repair assessments in Ravenhall.
DOES TEMPERATURE REALLY AFFECT A WINDSCREEN CRACK?
Yes. Glass expands in heat and contracts in cold, and a chip is a weak point in that surface. Quick swings, like a cold morning followed by a warm afternoon, put uneven stress on that weak spot, which is a common reason small chips spread into long cracks during spring.
CAN I LEGALLY DRIVE WITH A SMALL CHIP IN VICTORIA?
It depends on the size and location. Under VicRoads’ roadworthiness requirements, certain bullseye or star fractures up to 16mm and cracks up to 150mm may be allowable within the wiper-swept area, provided they do not impair the driver’s vision to the extent that the vehicle cannot be driven safely. If you’re unsure, have the damage professionally assessed.
HOW QUICKLY SHOULD I GET A CHIP REPAIRED?
As soon as you reasonably can. There’s no fixed cut-off, but chips left exposed to dirt, moisture, and temperature swings are far more likely to spread into a crack that can no longer be repaired.
WHAT IF MY WINDSCREEN CRACKED AFTER A SMALL BUMP OR SCRAPE?
That’s a different situation to a stone chip. A knock can affect the panels and frame of your car, not just the glass, so a full smash repair assessment is the safer option. If the car isn’t safe to drive, a towing service in Ravenhall can get it to a workshop without adding further damage.
WILL A REPAIRED CHIP BE AS STRONG AS THE ORIGINAL GLASS?
A professional chip repair is designed to stabilise the damaged area and improve its appearance, although the glass may not return completely to its original condition.
