Windscreen chip repair, explained
A windscreen chip is an impact point, often caused by road debris, and left untreated it can quickly spread into a cracked windscreen. We fix small chips by carefully cleaning out dirt, pulling a vacuum to remove air, injecting a liquid acrylic resin, then curing the resin with ultraviolet light so the repair bonds to the glass. The result restores strength, improves clarity and makes the blemish almost invisible, which means a safer, clearer view for you. On average, a chipped windscreen repair takes about half an hour, and in many cases we can complete your appointment within an hour at your chosen location so the interruption to your day is minimal!
Small chips can seem harmless, but vibration, rain and sudden temperature changes can turn a minor chip or crack into a serious fault, so we always recommend booking as soon as you notice any car windscreen damage and we will quickly assess what is repairable to stop further spread.
Chips, cracks and what is repairable
Not every chipped or cracked windscreen can be fixed, and size, depth, location and the type of break decide whether a repair or replacement is safer.
- Repairable in most cases: a windscreen chip smaller than a 10p coin, away from the edge and outside the driver’s line of sight.
- Needs professional assessment: chips with small cracks or a windscreen crack that measures around 3 cm, or any chip or crack that sits close to the edge.
- Likely replacement: chips larger than a £2 coin, larger cracks, damage that runs to the edge, or anything that harms the driver’s view.
MOT rules and legal risks for a cracked windscreen
MOT rules are clear, and it helps to know where you stand before test day. Damage over 10 mm in a 290 mm wide zone centred on the steering wheel can cause an MOT fail, and damage over 40 mm anywhere else on the screen can also fail. Driving with a cracked windscreen that restricts the driver’s view can lead to a fine and three penalty points, and if you have an accident while driving with a damaged windscreen you could face more serious charges.
We help drivers avoid MOT hassle by repairing chips quickly and advising when a full replacement is safer, which means fewer surprises and a smoother test. If your MOT is due and you spot a chip or crack, arrange an appointment and we will deal with it before test day so you can arrive with one less thing to worry about.
Windscreen repair cost, insurance & what you pay
The cost to fix a chipped windscreen is typically between £40 and £118, with many straightforward jobs around £60, and we will always explain the price before we begin. A windscreen replacement can range from £188 to £1,650 depending on your vehicle, the glass specification and sensors, so we will confirm your windscreen repair cost or replacement estimate in advance with no hidden extras, and you can then choose what suits you best.
Windscreen cover is often included in comprehensive car insurance, and many insurers cover repairs with no excess while you usually only pay an excess on a replacement. Claiming for windscreen repair usually does not affect your no claims bonus, and we can handle the claim with your insurer to save you time and admin. Check your insurance policy for the level of cover and any excess, then tell us your policy number and insurer and we will help you make a claim quickly and clearly.
You can claim under your car insurance for windscreen repair or replacement, and windscreen cover may mean you pay nothing for a repair while an excess often applies to a replacement windscreen. If you prefer to pay directly, we keep costs clear and competitive so you can choose the route that saves you money.
Can we fix a crack, or do you need a replacement?
A windscreen crack can sometimes be stabilised if it is short, shallow and away from the edge, but a cracked windscreen usually means replacement, especially when the crack is long, in the driver’s view, or near the screen edge where stress is highest. For complex screens with rain sensors or heating elements, replacing the glass and calibrating systems is often the safest path, and we will explain why so you can make an informed decision.
We will assess the chip or crack, explain the repairable limits in simple terms, then advise on repair or replacement. If you need a full windscreen replacement, we supply the correct glass for your car, including screens with rain sensors and heating elements, and we calibrate where required. If all you need is chip repair, we fix it on the spot so you get your chipped windscreen repaired without delay and with complete reassurance.
The R2V repair process in detail
We start by shielding the area and removing loose dirt so the resin can bond cleanly. A bridge tool seals over the chip, a vacuum draws out trapped air, and resin fills the cavity carefully to reach all micro fractures. Ultraviolet light cures the resin to bond with the surrounding glass, then we level the surface so wipers glide smoothly and the finish looks neat. The repair restores structural strength, prevents moisture ingress and improves clarity, which helps your screen last and your view stay sharp.
Typical timings are straightforward, with set-up and cleaning taking a few minutes, resin injection a few more, curing around ten minutes and finishing a couple of minutes, which is why most appointments complete in about 30 minutes and we can often get your chipped windscreen repaired during a work break.
Replacement windscreens and ADAS
If repair is not an option, we arrange a new windscreen that matches your vehicle specification so safety systems continue to work as designed. Many modern cars embed sensors into the screen, and we fit and, where required, calibrate systems that rely on the glass, including rain sensors and other ADAS features. Heated screens contain fine heating elements that must be matched to the vehicle, and using the correct replacement windscreen prevents faults and protects safety systems.
We provide mobile windscreen replacement across the UK, with careful fitting to manufacturer standards and clear advice on safe drive-away times, along with any calibration checks you may need after replacing the screen.
Mobile service across the UK, with minimal hassle
We come to your home, work or another safe location so you do not need to drive to a garage with a cracked or chipped windscreen, and booking is simple and friendly. Share your vehicle details, describe the chip or crack and tell us your location, then we will confirm availability, give you the windscreen repair cost or replacement price and set an appointment that suits you. Our mobile vans carry professional equipment to fix or replace your screen on site, and we tidy up before we leave so everything feels easy.
Drivers tell us they value a service that saves time and hassle, which is why we deal with the paperwork if you choose to claim, keep you updated about your appointment and make sure the job is finished neatly.
DIY kits, safety limits and why speed matters
A windscreen repair kit can help with very small chips if used correctly and in dry conditions, and kits typically cost £10 to £20. The catch is simple, poor application traps air or dirt, the chip can quickly spread into a larger crack and you might still face a replacement, so for safety we strongly recommend professional assessment before you try to fix a chip yourself, especially near the driver’s view or the edge.
Repairing early is cheaper than replacing later, because a chipped windscreen that is fixed promptly is less likely to become a cracked windscreen, less likely to fail an MOT and more likely to be covered in full by windscreen cover with no excess to pay.
Practical tips to prevent windscreen damage
- Keep a sensible distance from lorries and vans to reduce the risk of road debris striking the glass.
- In cold weather, avoid boiling water on ice. Use an ice scraper and de-icer instead to avoid sudden temperature changes.
- Replace worn wiper blades so grit is not dragged across the screen, and clear rain properly.
- Repair small chips quickly so they do not turn into small cracks or larger cracks.
Repair or replacement: how we help you choose
We assess the chip or crack, measure and photograph it, check the edge zones and evaluate stress points so the advice you receive is based on evidence rather than guesswork. We explain the risks, discuss the cost difference and confirm whether repairable criteria are met, then if repair is safe we fix it there and then, and if replacement is the right call we arrange a full windscreen replacement, source the correct glass and sensors and book fitting at a time that suits you. Either way, you get a clear plan, a fair cost and a job done correctly by people who care about doing it right.
Insurance support that keeps things simple
If you want to claim, tell us your insurer and policy number, and we will confirm coverage, check your excess and process the claim so there is less hassle for you. Windscreen cover on comprehensive car insurance often allows repairs without excess, and replacing a screen usually only requires you to pay the stated excess, but every insurer and insurance policy is different so we confirm details before we start. Our aim is to save you time, money and effort while keeping your vehicle safe, and to keep communication clear at every step.
FAQS
