Early damage assessment
Small chip, sensible next step.
A suitable repair can help restore strength and reduce the chance of damage spreading. Suitability depends on the chip’s size, depth, position and condition.
01
Stone chip repair
Professional resin repair for suitable windscreen chips before they develop into larger cracks.
02
Photo assessment
Send a clear close-up and a wider photo showing the chip’s location for faster initial advice.
03
Crack assessment
If the damage has spread, we will explain whether replacement is likely to be the safer option.
04
Mobile repair
Home and workplace appointments may be available where the chip and working conditions are suitable.
05
Cars & vans
Damage assessment for private cars, work vans and selected light commercial vehicles.
06
Clear expectations
Repair is intended to strengthen the damaged area; a small cosmetic mark may remain afterward.
Can it be repaired?
Size matters. Position matters too.
Small chips can often be considered for repair, but long cracks, edge damage, deep contamination or damage in a critical viewing area may require replacement. A photo is useful, but final suitability is confirmed by inspection.
A small, clean chip that has not spread and is positioned where a safe repair can be completed.
Replacement may suit
A spreading crack, edge damage, multiple impacts or damage that affects safety and visibility.
British Standard guidance
Repair zones and safe assessment.
BS AU 242b:2022 is the current BSI code of practice for repairing impact damage to laminated vehicle windscreens. It guides technicians on repairable damage, permitted positions, repair procedures and finished-repair assessment.
Premier Windscreens guide to repair zones. Final suitability is always confirmed by inspection.
Zone A
Directly ahead of the driver
This critical viewing area is centred on the steering wheel and is 400mm wide for cars and light commercial vehicles. Damage must fit within a 20mm-diameter circle to be considered for repair.
Zone B
The remaining swept area
Outside Zone A, suitable damage may be considered when it fits within a 40mm-diameter circle. Size alone does not guarantee that a repair is safe or appropriate.
ADAS area
Camera zones are excluded
Damage in glass that supports, or previously supported, an ADAS component is not repaired. Replacement and the appropriate ADAS calibration will normally be required.
Important: These measurements are a simplified customer guide. Damage type, depth, contamination, distance from the glass edge and the vehicle manufacturer's camera zone must also be assessed by a technician. Read the official BS AU 242b:2022 listing on BSI Knowledge.
Damage size guidance
How large can the damage be?
Under the current two-zone guidance, the maximum size considered for repair depends on where the impact sits. These limits are a starting point only: the damage type, depth, contamination, edge position and camera area must also be assessed.
20mm
Zone A
Damage directly ahead of the driver may be considered when it fits completely inside a 20mm-diameter circle.
40mm
Zone B
Across the remainder of the windscreen, suitable damage may be considered when it fits inside a 40mm-diameter circle.
<10mm
After repair
The finished repair must not interfere with the driver's view and should finish level with the surrounding glass.
Post-repair visibility: the finished result should be invisible or only just detectable, with any remaining visible repair less than 10mm across. Every repair is checked before the vehicle is returned.
From photo to repair
How stone chip repair works.
1
Clean and prepare
The damaged area is inspected, cleaned and dried so that contamination and moisture do not compromise the repair.
2
Inject clear resin
A specialist clear resin is introduced into suitable damage and cured to stabilise the affected area.
3
Inspect the finish
The finished repair is checked for a smooth surface and acceptable result. The impact point may remain visible.
What to expect
A repair strengthens the area—it may not disappear.
Windscreen repair is primarily a structural process designed to stabilise suitable damage and reduce the risk of spreading. The impact point can remain faintly visible, and cosmetic invisibility cannot be guaranteed.
